How do I Tell the Difference Between Fiberglass & Acrylic Tubs?

Updated July 19, 2017

There are two main types of tubs: acrylic and fibreglass. Both are smooth and glossy. Both are able to be repaired, should that need arise.


Acrylic bathtubs are warm. They will scratch if an abrasive cleanser is used. Acrylic tubs are moulded from one piece and sometimes reinforced with fibreglass for added stability. They are nonporous.


Fibreglass tubs are created by spraying bits of glass onto a gel coating. They are strong and are also porous.

How to Tell the Difference

Fibreglass tubs are typically thicker than acrylic tubs. Acrylic tubs tend to get thin around the edges, where the mould bends. Acrylic tubs tend to come in more colours than fibreglass tubs.
