And of course, space matters, so be sure to read our guide to bathtub sizes and dimensions to ensure you’re getting the right one.
Types of Bathtub Material and Why it is Important
With bathtubs, the material really does matter. Some retain heat for longer while others are simpler to install, and built to last for decades. If you love long soaks, you probably want a material that holds heat well too.
But perhaps you’re just in search of something that’s more low maintenance, quick to clean and budget friendly where materials such as acrylic does the job well.
How much maintenance is needed will also depend on the material you choose. Some tubs of wood or copper are absolutely beautiful, but require more maintenance. It all comes down to a trade-off between comfort, cost and upkeep.
Common Bathtub Types Summary
1. Acrylic Bathtubs
Plexiglass tubs are popular for a reason, they’re lightweight, simple to install, and you get more for what you pay for. Acrylic is non-porous, so it is also resistant to mold and mildew, which means less scrubbing.
The material retains heat quite nicely, as well, so you won’t need to worry about getting cold as quickly during your bath. And we can’t neglect the diversity. Acrylic tubs have a million shapes and sizes so you shouldn’t have a problem finding something to fit your bathroom.
Pros:
- Lightweight and quick to install
- Good heat retention
- Affordable
- Easy to clean and maintain
Cons:
- Can scratch over time
- Not durability like cast iron
Perfect For: Anyone on a tight budget, that wants a variety of possibilities.
2. Cast Iron Bathtubs
Now, if you prioritize durability, cast iron tubs would be hard to beat. These things are made to last, and they’re great for anyone who wants something that will outlast all its competitors. Cast iron retains heat very well, so half way through your bath, you won’t find yourself trying to keep the water warm.
And they look so classic and timeless. They don’t go out of style. But I can tell you they are heavy, just so you know. A cast iron tub is not for the faint of heart. It’s an investment, but it’s an investment that has the potential to last you a lifetime.
Pros:
- Extremely durable and long-lasting
- Fantastic heat retention
- Classic, timeless appeal
Cons:
- Quite heavy and not simple to install
- Expensive
Best For: People who are seeking a tub that is both durable and makes a statement in their bathroom.
3. Fiberglass Bathtubs
Fiberglass is the most economical choice if you need to save money. It’s lightweight, easy to install and available in many shapes. But it’s less durable than some other materials.
Fiberglass shows scratches, staining and fading more readily than other materials, so you may find yourself having to replace your fiberglass shower sooner than you would any other showering option. But if it’s a fast, cheap fix you’re after, fiberglass gets the job done without emptying your pocketbook.
Pros:
- Very budget-friendly
- Easy installation
- Lightweight
Cons:
- Susceptible to scratches, stains, and fading
- Not as durable as other
Best For: Homeowners on a budget who need a simple solution now and won’t mind coming back to replace it in a few years.
4. Porcelain-Enameled Steel Bathtubs
Durable steel construction with porcelain enamel offers even heating. You’re looking for something that will last and is easy to maintain. The finish is shiny and looks nice, and the tub is fairly sturdy.
That being said, steel does not hold heat as well as other materials, so your bath water may cool down more quickly. Oh, and steel dents and scratches are easier than you probably realize, too, so you’ll definitely want to be a bit grittier.
Pros:
- Durable and long-lasting
- Glossy finish
Cons:
- Poor heat retention
- More prone to breaking or scratching
Best For: Folks searching for a tough tub, but don't mind sacrificing some heat retention.
5. Stone Resin Bathtubs
Stone resin baths are the height of luxury. Constructed of natural stone and resin, these tubs have a modern, clean appearance you won’t find elsewhere. They’re not just beautiful, but they hold heat really well, so you can enjoy a warm, soothing bath. The quality is second to none, and these tubs are made to last.
Of course, they come with a high price tag, and their weight can make them difficult to install. But if you’re seeking a luxury experience, then you’ll want to steer yourself towards stone resin.
Pros:
- Modern, luxurious appearance
- Excellent heat retention
- Extremely durable
Cons:
- Expensive
- Heavy and harder to install
Best For: People who want to feel like they’re at a luxury spa in their bath.
6. Copper Bathtubs
Copper tubs are a real have-the-show-stopper piece. They also happen to be beautiful and antibacterial, which is a boon for germophobes. Copper gains a lovely patina with age, making it even more attractive.
They’re very good at retaining heat as well, so your bath will remain warm and relaxing. Just be aware that copper tubs are expensive and need regular scrubbing to maintain that lovely sheen.
Pros:
- Antimicrobial properties
- Lovely patina that takes time to form
- Excellent heat retention
Cons:
- Very expensive
- Needs an occasional polish to prevent tarnish
Best For: Those who want something that looks a little more special and expensive, with some health benefits to boot.
7. Wooden Bathtubs
Wooden bathtubs have a warm, woodsy beauty that you won’t get from other tub materials. They are made from beautiful woods such as teak and give you a warm, spa-like bath experience.
But just keep in mind that wooden tubs require more maintenance than most. And you’ll have to reseal them regularly to prevent water damage. Even so, if you like the idea of a spa-like, nature-inspired bathroom, a wooden tub might be just what you need.
Pros:
- Unique, natural aesthetic
- Spa-like, luxurious feel
Cons:
- High-maintenance
- Requires regular sealing to avoid staining
Best For: Anyone who wants a sumptuous natural look, and is willing to put in some effort to care for them.
What Kind of Material Should You Choose For Your Needs?
Selecting the best bathtub material really comes down to what works for your lifestyle and bathroom needs. If you want something durable and ageless in beauty, cast iron and stone resin are options to consider. But if you have a smaller budget to work with, or want a quick fix, acrylic or fiberglass will still get you a comfortable bath without the colossal price.
Consider how much upkeep you’re willing to commit to and what works with your bathroom’s aesthetic. A wooden tub might be beautiful, but it also requires some extra labor. But on the flip side, acrylic is super low-maintenance.
