Top 10 Stone Resin Bathtub Manufacturers & Brands

Stone resin bathtubs are the most luxurious and comfortable bathroom fixtures, gaining momentum in sales and becoming popular amongst middle-class households. Brands are now focusing on stone resin bathtubs' features, such as their seamless design, which is an excellent alternative to other porous, high-maintenance materials like fiberglass, acrylic, and traditional cast iron.

One of the key features that makes stone resin bathtubs stand out amongst other bathing fixtures is their ability to retain heat. Stone resin is a composite material that consists of natural stone particles and resin. It offers low conductivity, ranging from 0.25 to 0.35. Owing to its high-thermal capacity, it allows water to stay at a comfortable temperature for 30 to 40minutes depending on the ambient conditions.
