Types of Bathtubs
Acrylic
A lightweight, modern option made from moulded plastic. Acrylic tubs are warm to the touch and are commonly found in newer homes or recent remodels. They're known for being easy to install and available in a variety of shapes and sizes.
Pressed Enamel Steel
These are made from pressed steel coated with a smooth enamel layer. They have a hard, durable surface and are often mistaken for cast iron because of their glossy finish. However, they're much lighter and easier to remove.
Cast Iron
The heaviest and most solid of all tub types. Cast iron tubs are made from molten iron and coated in thick enamel. These tubs are built to last and are often found in older homes or those with a vintage-inspired design.
How to Identify Your Bathtub Type
Not sure what kind of tub you have? Here are expert tips to help you figure out what type of bathtub you have:
Try the Knock Test
One of the easiest ways to get a clue about your tub's material is by knocking on it with your knuckles. This quick sound test can give you a lot of insight.
Acrylic tubs produce a dull, muffled thud and feel slightly soft and warm to the touch.
Pressed enamel steel tubs sound hollow, like tapping on a tin can, and feel cool and metallic.
Cast iron tubs sound solid and heavy, more like knocking on a rock, with minimal vibration.
Consider the Weight
Weight is another big clue. The weight of your tub can help you tell what it's made of.
Acrylic tubs are lightweight and may shift slightly if not fully secured.
Pressed enamel steel tubs are heavier but manageable for two people to move.
Cast iron tubs are extremely heavy and often require specialized equipment for removal.
Look at the Finish
The finish of the tub can also help you figure out what you're working with.
Acrylic tubs feel smooth, slightly flexible, and warm.
Pressed enamel steel tubs have a hard, glossy finish similar to cast iron but with a thinner feel.
Cast-iron tubs feature a thick enamel coating and are commonly found in vintage styles.
