What is the Best Bathtub Material?

Selecting the best bathtub for your bathroom is one of the many decisions you need to make when remodeling your bathroom. From faucets, finishes, and accessories the list goes on.

A major part of the process is deciding which bathtub material will best suit your bathing needs. We will explore a few of the more common bathtub materials with some positive and negatives.

What are bathtubs made out of?

Bathtubs have really evolved over time, a decision that was once pretty simple has now become overwhelming. Some materials are porous,  stain resistant, while others are brilliant at retaining the heat of the water for a long time.

In this segment we will break down a handful of the most popular options from Cast Iron, Acrylic, Stone Composite, Copper and Fiberglass.

Cast Iron

PROS: Cast Iron is an extremely durable material. A cast iron bathtub is made from porcelain and iron and then coated with enamel to prevent chipping.  This material will stand the test of time.

It is also non-porous, meaning that air cannot move through the surface. It is fully sealed and smooth.

The result of a non-porous material? It is more hygienic since it can be cleaned properly. This also means that it will retain the heat of the water for a longer bath.

CONS: Cast Iron is extremely heavy. It would be recommended to reinforce your floors before installing a Cast Iron Bathtub. This material is more expensive as well.

Stone Resin

PROS: Stone Resin imitates the look and feel of a luxury stone finish. It is non-porous, which is mold and mildew resistant and retains the heat of the water much like a Cast Iron Bathtub.

It has an incredibly long life-span and minor chips or scratches can easily be repaired. They have a gel-coat surface that increases their resistance to scratches, or minor damages that can occur during installation.

CONS:  Stone Resin Bathtubs tend to be more expensive than Acrylic or Fiberglass.
