In addition to being lightweight and affordable, there is a reason this material has a bit of an edge when compared to other commonplace bathtub materials such as acrylic, fiberglass, porcelain and cast iron. The material will not warp overtime unlike fiberglass and acrylic, nor will it break, shatter or chip due to heavy impacts from accidental drops or falls like porcelain will and, as stated before, the material is as durable as cast iron with being four times lighter than it. It is non-porous, meaning it will not absorb water unlike fiberglass and acrylic, which means the structural integrity of it will never change, it also has excellent heat retention on par with higher end materials like enameled steel and copper. And lastly, stone resin is very eco-friendly, made from recycled materials with an entirely green production model. With the added benefit of being a durable material, it will also not create waste as stone resin bathtubs will last several lifetimes.
