The generous Elise soaking tub(PDF) anchors the new Boutique Collection of high-end solid-surface bath fixtures. In addition to Elise, the collection includes four handmade sink styles. Each piece is constructed of the maker's ESS (engineered solid surface) composite material, made of a mixture of ground natural minerals and binding agents. The resulting product is nonporous and resists stains, mold, and mildew. 800-783-8827.
