Boutique Collection tubs, sinks and shower bases are constructed using a material that MTI calls "Engineered Solid Stone®”, because that's what it is. "ESS®" is a mixture of ground natural minerals and binding agents that are liquefied, poured and then hardened. The result is molded stone. Solid through-and-through, with no layers, hollow or void areas.

There are a number of products on the market that may appear to be made in the same way as those in MTI's Boutique Collection, but in reality they are quite different. Products such as these are generally referred to as "solid-surface" or "composite". They may be constructed using cultured marble, limestone or something similar. There may also be hollow areas in the product, and frequently surface coating.

MTI's Boutique Collection products are more than solid-surface. They are consistently solid all the way through, with no voids and no surface coating. The material is also quite "Green", with approximately 65% of the material being organic minerals mined from the earth. They are non-porous, stain, mold and mildew-resistant. All of which makes them easy to clean and maintain for many years of enjoyment and service.

And best of all, they are all manufactured and individually handcrafted in the USA. See Boutique Tubs, Sinks and Shower Bases.
