Cast Iron or Acrylic Clawfoot Bathtub

Acrylic Versus Cast Iron Clawfoot Bathtub

Customers often ask us which is better, a Cast Iron Clawfoot Bathtub or an Acrylic Clawfoot Bathtub? It's a legitimate question that is not quite so easy to answer. Many articles exist online comparing these two types of stand alone bathtubs but it can still be hard to make an informed decision. Both Acrylic and Cast Iron Clawfoot Tubs have pros and cons depending on your situation.

Freestanding Clawfoot Tubs

Take a minute to read through this article and learn how to determine which is best for you. At the end of the article you will read some quotes collected from many places around the web. They are real quotes that real people left as comments on various home improvement discussion forums. Our goal was to collect this information together in one place to help make your decision a bit easier. Articles like this one can inevitably come off like a sales pitch. That is not our intention, hence the real user quotes. Our goal here at is to help you find the right Tub for you, not to convince you to buy something you don't need or want.

That being said, at we do have over 40 years' experience in the plumbing industry. Using our expertise we put together this article to provide you with the information you need to compare and decide for yourself. If however you don't have time to read the entire article, below is the long and short of it from our perspective. Read on for more detailed information and additional comparison points.

Cast Iron Clawfoot Tubs

Cast Iron Clawfoot Tubs feel nicer, are sturdier, last longer (think generations), and retain heat better allowing for longer soaking time. If you plan to mount additional hardware like a Clawfoot Tub Shower directly to your Tub, you may need to go Cast Iron in order to support the extra weight of these fixtures. The downside is Cast Iron Tubs are heavy, making them sometimes unsuitable for upstairs bathrooms. A Cast Iron tub will definitely make your contractor complain as it may take four people to lift. Cast Iron Tubs are also more expensive than Acrylic, but in recent years prices have come down a bit due to high demand.

Acrylic Clawfoot Tubs

Acrylic Clawfoot Tubs are lighter and easier to move around and install. They are great for upstairs bathrooms. Acrylic Tubs are warmer on the initial touch and unlike Cast Iron Tubs, they do not need to be filled with hot water in order to heat up (they basically maintain the same temperature as the room). Acrylic is less expensive, so if you are on a budget an Acrylic Clawfoot Tub is the way to go. The downside is that Acrylic Tubs do not retain heat as well as Cast Iron Tubs (although this is somewhat up for debate). They also do not add the same value to your home since high-end bathroom plans pretty much exclusively demand real Cast Iron Tubs.

With so many options and decisions when doing a remodel or building a new home it can be complicated and overwhelming to decide which Tub will be best for you. To keep it SUPER simple, ask yourself these two (in our opinion) most important questions:

  • Is my bathroom upstairs? If yes, we'd recommend Acrylic. If no, go Cast Iron - you won't regret it.
  • Does my budget have space for Cast Iron? If yes, we'd recommend Cast Iron. If no, go Acrylic and you will still be very happy.

Bottom Line is that either type of Tub will be very enjoyable, look great, and last for many years. A bit later in this guide there will be more details on the differences between Cast Iron and Acrylic. However first let's look at some of the positive features offered by both types of Free Standing Clawfoot Tubs. Remember, these two types of Tubs do not exist in a vacuum. There are also those normal, small, built-into-the-wall type of Tubs. Both Cast Iron and Acrylic Freestanding Clawfoot Tubs are definitely better than that...But let's try not to get too far off topic.

Slipper Clawfoot Tub

Slipper style tubs are raised at one end. The raised end provides a back and head support allowing you to really sink into it. Slipper claw foot tubs are distinguished by their high-back construction which provides a more comfortable seating position. If you like lounging in a tub and being able to rest your head, a slipper style tub is for you! The Clawfoot Tub Faucet and Drain install at the lower end of the tub so they will be out of your way as you lay back.

Double Ended Clawfoot Tub

Double Ended Tubs are rounded for your choice of bathing position. They feature a center drain configuration and a Faucet mounted on the long side of the Bathtub. This allows both short ends to be free from hardware and available for relaxing. Depending on your room configuration a Double Ended Claw Foot Tub can be great. Especially if you want to place the tub in a more central location, this style of Clawfoot Tub allows it to really become a focal point of the room.

Double Slipper Tubs offer the best of the Slipper Tub and the Best of the Double Ended Tub. The central drain placement and side-mounted Tub Faucet allow the bather to take advantage of both high ended head rests. The larger size Double Slipper Tubs can accommodate two people, offering comfortable head and back rests for both. Large Double Slipper Clawfoot Tubs represent the height of comfort and luxury and offer a wonderfully relaxing experience.

Pedestal Freestanding Bathtubs

Pedestal tubs mimic 1920s and 1930s art-deco style Free Standing Tubs. Rather than having "feet" like a normal Claw Foot Tub, the Pedestal Tub sits on a wide base. Pedestal Tubs offer a more modern take on a Classic ClawFoot Tub while still preserving its best qualities. These large, deep soaking Tubs offer the same great relaxing features as a Claw Foot Tub but offer you a chance to get creative with your bathroom design.

Classic Roll Top Clawfoot Tub

The original and basic Clawfoot Tub with one flat end and one rounded end. The rim of the tub is a roll top style creating a smooth edge. Faucets are typically mounted on flat end of the tub. This is the quintessential style of Clawfoot Tub. Produced using Cast Iron, large numbers of these tubs were made in the early 1900s, many of which are still around today, and are often sold as vintage or refurbished. This timeless design is classic hasn't changed much over the years. New Tubs in this style are available only in high-quality Cast Iron, just like in the old days.

Cast Iron versus Acrylic Clawfoot Tubs

Now that you are familiar with some of the different types of Clawfoot Tub, we will discuss a bit more about the difference between Acrylic Clawfoot Tubs and Cast Iron Clawfoot Tubs. As mentioned above there are good and not-so-good aspects of both. You need to consider your specific situation and decide which will work best for you.

Clawfoot Tub Heat Retention

Heat Retention seems to be the most debated topic when it comes Acrylic versus Cast Iron Bathtubs. Because Acrylic tubs are essentially plastic, they have a more even temperature. This means if you touch an Acrylic Tub before it's filled with water, it will feel basically the same temperature as the room. Cast Iron Tubs on the other hand will likely feel cold to the touch before being filled with water. Acrylic Claw Foot Tubs are usually a better insulator against heat transmission than Cast Iron Claw Foot Tubs (that is to say that they warm up faster than a Cast Iron Tub). Although once heated, a Cast Iron Tub will tend to keep water warmer longer than an Acrylic Tub because of the greater thermal mass of the Cast Iron Tub. The user comments below seems to indicate that this is the case.

A Cast Iron Clawfoot Tub is made of Iron. The Iron heats up when you add warm water. Since once Iron is hot it can hold that heat, it will keep the water in the tub warm for a long time. It will radiate that heat back into the water and into the room. Cast iron tubs hold heat extremely well, making them the ideal tub for a user who likes to sit and soak for extended periods of time. This is not to say that Acrylic Clawfoot Tubs do a bad job. In fact newer techniques for manufacturing Acrylic Tubs allow them to hold heat for a long time as well. Cast Iron Tubs really are still a bit better in this regard but remember, you can only stay in a Tub for so long before you start looking like a raisin so this issue may be less important than it seems. Both types of Tub offer a large, deep-water soaking experience, sure to be enjoyable for your whole family!

Clawfoot Tub Weight

With regards to weight it is a clear win for Acrylic or is it? Certainly weight is an issue that must be considered. If you plan to install your Clawfoot Tub on the second floor you should make sure you have spoken to a professional and know that the room can support the weight. Whether you go Acrylic or Cast Iron, weight is a factor that must be considered when purchasing a Clawfoot Tub. Regardless of the weight of the Tub itself, you have to contend with the weight of water. At 8 pounds per gallon a 60 gallon tub full would weigh 480 pounds just from water. Add to that a person (or two) plus the weight of the tub. Cast Iron Tubs typically weigh around 300 pounds vs. an Acrylic Clawfoot Tub averaging around 120 pounds. So you can see that weight is definitely something that must be considered.

This also means that simply moving the tub into place can be a real project. You may need 4 people to lift a Cast Iron Tub and get it placed where you want. An Acrylic Tub only requires 2 people to lift. It's a bit like moving a couch - not so much heavy as bulky so you need more than one person. On the other hand, once your Tub is in place, you will likely never move it again and the heavier weight may actually be a benefit once you start using it. The most important thing to take home from this weight discussion is that you need to make sure the surface you wish to place the tub on can handle the weight (especially applicable in second story bathrooms).

Clawfoot Tub Durability

Durability is another issue you must think about. Both types of Tub have some good and bad aspects. Cast Iron Tubs are undoubtedly more durable on a base level. With proper maintenance Cast Iron Bathtubs can last for generations. They require less upkeep than acrylic and may be the proper choice for bathrooms that receive a lot of traffic. Cast Iron Claw-foot tubs are made to last: Stories abound of people restoring old homes and keeping the original Clawfoot Bathtubs that came with the home because they're still in perfectly good condition.

Cast Iron Tubs are coated on the interior with a layer of Porcelain. The Porcelain interior provides excellent abrasion, stain, and wear resistance, often better than metals. This is very nice but it can be subject to cracking (for example if you drop something heavy) and may require re-glazing or resurfacing to repair. Acrylic Clawfoot Tubs on the other hand will never crack. Cast Iron's Porcelain surface resists scratches while Acrylic Tubs are more subject to scratching over time. To repair scratches on an Acrylic Tubs is relatively easy as most can be easily sanded and then buffed away to restore the shine. With proper care, scratching of Acrylic Tubs is not really a big issue.

Clawfoot Tub Cleaning

Cleaning is another area these two types of Tub differ. Because Acrylic bathtubs are more prone to staining than Cast Iron Bathtubs a more rigorous cleaning schedule should be followed. The surface of an Acrylic Tub is very easy to keep clean. There are no pores for dirt to penetrate, so dirt will just rinse off. For sanitary purposes, you should clean your Bathtub with a non-abrasive soap. Dishwashing detergent such as Joy®, Palmolive®, Ivory®, etc and a soft sponge or cloth is all that you need. If you spill something on the bathtub and need something stronger, the following are SAFE to use: Fantastic®, Tackle®, Top Job®, Formula 409®, ScrubFree®, Calgon Bath®, Windex®, Clorox Bleach®, Spiffits® Bath, Glass Plus®, and Spic & Span Powder®.

DO NOT Clean Your Acrylic Bathtub with Paint Thinner, Goof OFF®, Scrubbing Bubbles®, Acetone, Lacquer Thinner, M.E.K. ® or other chemicals that attack the structural integrity of Acrylic plastics (including, but not limited to, acetones).

The Porcelain layer that lines the interior of a Cast Iron Clawfoot Tub resists stains and is a good choice for bathrooms with heavy use. We recommend using a mild, non-abrasive cleanser for the routine cleaning of any tub with a Porcelain interior. We also recommend you dry the porcelain interior after each use. For tougher stains, you may use a cleanser such as Bon Ami® or ZUD®. Zud is a non-abrasive cleanser that dissolves rust, mineral stains, hard water deposits, and soap scum. Make sure to fix a leaky right away as water deposits can build up and be hard to remove.

Of course Price is an ever important consideration. Cast Iron Tubs are almost always more expensive than their Acrylic counterparts. Cast Iron Tubs require more work and more expensive raw materials to properly manufacture. The end product is very nice but like anything, cost must always be considered. If your budget prohibits purchasing a Cast Iron Tub, an Acrylic Tub may be a wonderful compromise.

Cast Iron Vs. Acrylic Tub Price

When comparing Cast Iron vs Acrylic Clawfoot Bathtubs it may be hard to decide but remember, you could be comparing a relaxing deep Clawfoot Tub with a normal drop-in Tub. Either Cast Iron or Acrylic will obviously be MUCH better than a normal tub. If you are working with a tight budget an Acrylic Tub may be a great way to get the experience of a wonderful Soaking Clawfoot Tub without the high price of Cast Iron. Paired with the proper Clawfoot Tub Hardware, a Clawfoot Tub creates a stunning look and a very useful and enjoyable function!

Quotes from Clawfoot Tub Users Around the Web

The above information should give you a pretty solid breakdown about the technical differences between different types of Clawfoot Tubs and the differences between the materials used in their construction. Comparing the pros and cons of the different types of Clawfoot Tub is something many people struggle with. We scoured the web looking for discussions about Clawfoot Tubs. Specifically we looked for topics where users were discussing which they prefer,Cast Iron Clawfoot Tubs or Acrylic Clawfoot TubsAcrylic Clawfoot Tubs. Below you will find some quotes from real people, many of whom are actual users of a Clawfoot Tub. This might give you some idea as to how people generally view the difference. Please feel free to add your own input or questions in the comment section below. It would be great to get some additional input, so if you have an opinion or thought, definitely leave us a comment!

"We have a cast iron tub (replaced a fiberglass tub/surround), and it is very easy to live with, easy to clean, ends up nice and clean and shiny every time. I much prefer the solidity of cast iron"

"Here is why people love them: They are deep. You can sit in hot water up to your chest without bending your knees. They are ideal for long soaks, because the cast iron holds the heat from the water longer than other materials. Acrylic tubs don't do that. There is just no comparison to the quality of bath you can get in an Cast Iron Bathtubsold cast-iron clawfoot tub. They also look really cool. If I could make just one change to my current house, I would put one in. Well, that and a fireplace, but definitely a cast-iron clawfoot tub."

"My main question was wrt toughness, actually, since the next tub we need will be in a kids' bathroom. For *toughness's* sake, I'm thinking cast iron, even though it's second floor. Maybe I will change my mind when it comes to actually getting the thing UP the stairs..."

"The acrylic ones seem so tiny and cheap-looking in comparison; they make me think of my daughter's Playmobil tub. Imitations of the real thing are rarely durably popular; everybody knows an acrylic claw-foot is a cheap substitute, and you will have a disposable item instead of something that could probably be coaxed into lasting another century."

"Cast iron is heavier, more expensive to purchase and install, will wear better and unlikely to move. Acrylic Clawfoot TubsAcrylic cost less, is less expensive to purchase and install, can get dinged and scratched and will move easily on the floor depending on how the tub filler and drain is installed. This can be a benefit since it can be moved and cleaned under and around."

"Besides from the pros and cons mentioned above, it depends on the FMV of your house. Cast iron is expected in more expensive homes. In less expensive homes, cast iron may be appreciated but acrylic would be acceptable."

"I had gone back and forth about acrylic vs cast iron. I can't remember all the pros and cons of each but I do remember wondering if the cast iron would be worth it for all the delays it caused us getting it and trouble for the GC getting it in. Now that we have it, I am so glad I didn't talk myself out of it. I just love the solid feel of it and how it radiates the heat back once you fill it up."

"I currently have an acrylic tub, but am planning a remodel and I have been following the threads on this forum having to do with cast iron vs acrylic tubs. I was in a hotel this past week and the cast iron tub itself was COLD! This was San Diego and the room temp was normal. I understand that cast iron will hold hot water hot longer, but what about when you first get in and touch the sides? Does this have to do with lack of insulation? Obviously this made me worry about cast iron in my old house during the snowy winter."

"A cast iron tub will feel cold until it is filled with hot water and then it will warm up and hold the heat keeping the water warmer longer. It will also radiate the heat back from the sides that are above the water line. Did you get in the hotel tub before it was full of water? It may take a couple of minutes before the iron heats up, but I've always found that by the time the tub was full the walls of the tub were warm."

"I did get in right away, as I am usually in a hurry to get going. Sometimes there is occasion for a leisurely soak, but not daily. For my part, I could adjust and wait just a little to get in for the tradeoff benefit of the solid feel of the cast iron, which I strongly prefer to acrylic. But the bath will be the only one in the house, and will be used as a shower for my husband, who often uses tepid or barely warm water. So I'm considering how much it matters that the tub will be cold to the touch for him too."

"I'm an interior designer, and I see a lot of statements that are very wrong. Even though acrylic can begin to look dull, there are way more pros than cons to having an acrylic tub. Acrylic tubs are lighter, stronger and easier to install than cast iron tubs. A cast iron tub requires more floor support, more labor to install and is more expensive to transport. Also, the natural warmth and thickness of acrylic tubs combine to preserve heat much longer than a cast iron tub. Someone stated above that cast iron holds more heat, not true. These days, acrylic tubs are being made of many different layers, allowing them to hold heat for longer periods of time. The only real benefit of a cast iron tub is that its overall look will last."

61-inch Small Cast Iron White Slipper Clawfoot Bathtub with Oil Rubbed Bronze Feet

"Cookware for ages has been made from cast iron - it is highly prized for it's heat retention capacities - it's elementary physics"

"We bought a new cast iron tub for our old house and love it. It holds the heat and scratches less than acrylic. The only thing we regret is not getting a double sloped tub with a center faucet to fit 2 people. Also, you should try out the tub in the showroom-they come in different sizes and since some people are taller/shorter than others, the tub length is important."

"Do you guys with Cast Iron ever worry about weight on the 2nd floor? I know it's heavy getting up there...but, with water and one person we are talking about around 1000lbs "

"You really can't top porcelain fired on cast iron for durability. But today's acrylic finishes are pretty good. The secret is in the cleaning. You must not use harsh cleaners, and you must clean regularly. If you let soap buildup/mineral deposits accumulate, you will damage the finish trying to clean it."

"It depends on the size of the tub. Cast iron is better and will retain its appearance a lot longer, but the larger tubs are not made in cast iron because they would be too difficult to cast correctly, and installing them would be very difficult."

"We are looking at the same decision. One problem with acrylic is how light the tub is. I assume you are talking freestanding. If so, you'll notice that if you bump into an acrylic tub with your leg you can knock it across the room. They just seem flimsy to me.

Cast iron is nice, but really heavy and expensive. I mean, if the tub is 500 pounds and you have negotiate it up a stairway (as we do) you want to think twice about it. Also, I worry about having that much weight on an upper floor. 500lb tub, plus 70-90 gallons of water, plus a person (or two) is a lot of weight, if you ask me."

"There's no question about it, cast iron."

"I don't know if the "holds heat" thing is true or not, but I do know that my Cast Iron Bathtubs cast iron holds heat quite well, this means that it holds cold quite well too. I usually have to have the bath planned out. I fill it with hotter water than I will bath with, and then it will warm the metal up. I bet the Acrylic Clawfoot Tubsacrylic warms up faster, but that probably means it dissipates the heat from the tub quite well too.... ahh, the decisions we have to make. "

"I have a salvaged tub. The cost to refinish it and paint the outside was close to $800. I found a new one for about $1300. To me, getting the new one might be a better idea."

72-inch Large Cast Iron Double Ended White Pedestal Freestanding Bath Tub

"I would do everything you can to hold on to it (Your Cast Iron Clawfoot Tub). They are actually surprisingly valuable - if you want to sell it, getting rid of it is not going to be a problem. Keeping it in place, though, not only adds value to your home (people love them) but it's by far the easiest solution: getting it out of the bathroom is going to be a beast. I don't know anything about refinishing them but if I were you, I would definitely look into fixing it rather than getting rid of it. I got rid of one in Baltimore - a half tub, at that; it's been a planter at my ex MILs in WV ever since, sigh - and I have regretted it ever since."

"You'd have to be nuts to replace a real clawfoot tub with an acrylic simulacrum of a clawfoot tub."

"i love my clawfoot tub - it makes the fact that i have the world's tiniest bathroom bearable. in fact, a clawfoot tub was one of the things at the top of my list when i was looking to buy a house."

"People love those things (Cast Iron Clawfoot Bathtubs). They hold heat better than a modern tub and also are actually deep enough for an adult to bathe in. Plus they add character."

Hi Helen, sounds like you have had a very tough experience. Really sorry it has been so difficult. Unfortunately it’s difficult to get good information about clawfoot tubs and the corresponding hardware as sometimes jobsite restrictions limit your options. Specific restrictions in your bathroom may mean the contractors options are simply limited. Often a cast iron tub will be too heavy for use on the second floor. Choosing an acrylic clawfoot tub seems like a sensible idea, but I see now you have now run into problems with the hardware not fitting. I think that if the contractors cannot figure out a work around, you may have to go back to vintage tub and bath and order the clawfoot tub faucet they recommended (Randolph Morris) to use with their tub. I know that Kingston Brass faucets do absolutely work on Acrylic tubs (Kingston Brass also sells tubs themselves), but it could be that the tub you have is just particularly thick, and outside of the design scope of the Kingston Brass products. To be honest, I have not heard of a case where a Kingston Brass clawfoot tub faucet wouldn’t fit an acrylic tub (even one made by another manufacturer). However, it could be that there are just some specifics about your tub that fall outside of the “standard” range. It may be worth it to push your contractor a little to understand why exactly the parts Kingston Brass recommended on the phone to accommodate the extra thickness won’t work in your case. If it is true that there is really nothing to be done to adapt the Kingston Brass faucet, you may need to order the Randolph Morris parts. It might be worth it to get another plumber out there to take a look. However, I understand you may want to just be done with the project, and I’d say ordering what Vintage Tub and Bath recommended might just be the easiest way to put this saga behind you. Hopefully it will all work out in the end, and I’m so sorry to hear how difficult this has been. I hope your comment will help other’s shopping for a clawfoot tub and faucet hardware. There are a lot of variables to consider with clawfoot tubs, and speaking to your contractor/plumber before ordering (or at least before the products are unreturnable) is a good idea. Best of luck to you and I sure hope everything turns out ok!

Dear Nick,
I thank you for this article. I am rather distraught at the moment as I had retained the original clawfoot tub to from our home circa 1905 and had planned to get it refinished by a local tub refinisher who has been in the business for 35 years. I never gave it a thought that we no longer had the feet as I had seen so many vintage repo fixture places that I thought I could just purchase new ones when it came time to refinish and install it in the main bathroom. This tub refinisher told me to discard the tub if I no longer had the feet. He said feet are made for the tub and you cannot purchase new ones. It was not an expense that I was expecting but I followed his advice and had the tub removed and set to replacing it with a new cast iron tub from Wayfair… who offered delivery to room of choice. But, the local Wayfair delivery team in Pittsburgh refused to deliver the tub… many different excuses. I would not ask my contractors to carry the tub upstairs as they are not professional movers so I canceled the order and decided to purchase an acrylic tub from Vintage Tub and Bath. Definitely not a the same quality as a cast iron tub and even the feet were not of the quality that the photo depicted. But it was custom painted and there was nothing I could do but keep the $1400 tub. It had the same tub wall faucet drillings as the cast iron tub from Wayfair so I didn’t even consider that there would be an issue with the Kingston Brass tub wall mounted shower and hand held spray system that I purchased. My Contractors cannot install the faucet to the water supply lines because the mounting fixture “stem” is about 1/4” too short to have enough threads to tighten the fixture. The contractor is telling me that Acrylic tubs are thicker than cast iron tubs and that is why this doesn’t fit.
I called Kingston Brass and they initially told me that their faucets work on both cast iron and acrylic tubs. And sent specs on couple of parts that could be used to accommodate the difference in the thickness. The contractor said these will not work. When I called Kingston Brass back they said they do not support installing it on acrylic tubs.
Vintage Tub and Bath has a very similar system (with a few minor differences) manufactured by Randolph Morris same as tub and they said that these are guranteed to work.

Fortunately I am able to get a refund on the fixture from Wayfair, but I am just confused at why this standard faucet would not work on this Acrylic tub, but would on a cast iron tub.

Do You have any words of wisdom or experience at installing faucets that mount on the tub wall on acrylic tubs? I am not sure that this team has installed fixtures for clawfoot tubs before.
Many thanks… and so sorry for the novel.

Hi Ellen, that is an interesting question and I will try to offer some guidance. An acrylic clawfoot tub is actually quite heavy, weighing around 120lbs (this may vary by manufacturer). This means that there’s not much danger of the tub tipping over if you just put your hand on the edge while getting in. In addition, the tub is actually secured to the ground via the drain which makes it very unlikely to tip unless you were to put enough force to overcome both the weight of the tub and also to literally rip the drain out of place. However I would not recommend sitting on the edge of a clawfoot tub. There is a whole set of accessibility products designed for people have trouble getting in and out of a tub. This is because the danger of sitting and slipping off somehow is even greater than the tub itself tipping. If you felt you actually needed the support and want to be able to sit on the tub edge, I would recommend a product called a Bath Shower Transfer Bench (You can see what I mean here on Amazon: ). Regardless of whether you have a cast iron freestanding tub, an acrylic freestanding tub, or just a standard bathtub, a product like this will make getting in and out safer than sitting on the tub edge. Hope this helps and good luck with your project!

I am considering buying an acrylic, clawfoot tub. Is there any danger in them turning over if you sat on the edge. Or put your hands on the edge, when stepping over the rim.

Cast iron conducts heat acrylic insulates ,so iron will radiate heat back but consume more energy than acrylic and will stay warm longer once the iron has heated up

Hi Pamela, Thanks for your comment. Cast Iron tubs are are really great but sometimes an acrylic tub just makes more sense. It just kind of depends on your particular situation. We tried to share everything we could find about the differences to help people make an informed choice. In the end both types of tubs will be very enjoyable – especially when compared to a tiny standard bathtub! If you are able to save an old vintage cast iron tub that would be wonderful! Very cool :)

Have been torn between salvaging the cast iron claw foot tub I have or getting an acrylic one. This article on tubs was very helpful. I do need new fixtures, so I am glad I found the this site. Oh yes, I have decided to keep my cast iron tub. It most definitely holds the heat better than an acrylic tub. I fill it with hot water only and it heats up the tub quite nicely.
