How to Tell What Your Bathtub is Made Of

Bathtub design and manufacturing have changed so much over the years. From acrylic and fiberglass to steel and cast iron, there are so many types of bathtubs, and these days, a lot of them mimic each other’s appearance. Because of that, it may be hard to tell what material your bathtub is, especially if you’ve had your bathtub for a long time or the bathtub was installed by whoever owned your home before you. Luckily, there are some tricks to help you narrow it down and find out what it’s made from. Team Tundraland can help walk you through these tricks, but first, it’s worth knowing why it’s important to find out what your bathtub is made of.

Why Should You Want to Find Out What Type of Bathtub You Have?

Trying out some of the following methods to help you discover what your bathtub is made of would be smart, and not just for the simple knowledge of what the answer is. It’s just as much about what the answer means for your bathtub’s lifespan, maintenance requirements, and any issues it has. Because not every type of bathtub lasts the same amount of time, nor does the same maintenance regimen work for every bathtub material.

Finding out what material your bathtub is made of can tell you when you should expect it to need replacing, and it can give you a chance to figure out an upkeep plan that keeps it looking its best and, in turn, prolongs its lifespan. And along those lines, knowing what type of bathtub you have can tell you whether you’ll be able to do anything about any stains, chips, cracks, or other issues that your bathtub has run into over time.

Grab a Magnet

Find a strong magnet and hold it against the wall of your bathtub. If it sticks, then your tub is made of steel or cast iron. Unlike metal, acrylic and fiberglass bathtubs are not magnetic.

Press on Your Bathtub

Firmly press your hand against the side of your bathtub. If it has a little give, it is made of acrylic or fiberglass. These materials have a little give or flexibility. Meanwhile, steel or cast iron will not have any give when pressed on.

Surface Damages

Surface damage differs by tub material. If your tub has chips or is rusty, it is made of some type of metal. However, if it has any scratches or cracks around it, it should be made of acrylic or fiberglass. Fiberglass bathtubs are also known for staining and fading over time. Acrylic bathtubs won’t fade.

Extra Supports

From removing panels and framing to looking in the crawl space or basement underneath the bathtub, there are many ways to see your bathtub’s support system. Cast iron bathtubs are extremely heavy and often feature extra supports underneath them. Most claw foot tubs are cast iron. Here’s what to look for:

  • Cast iron has supports that look pebbly.
  • Steel supports look metallic.
  • Fiberglass supports look like a bunch of strings.
  • Acrylic supports appear to be smooth.
