Born from the fine-stone trade, Northeast Ohio’s Regal Building Products makes porcelain wall-panel systems for showers and other wet areas. Its Synthesis and next-generation Touchstone systems bond real large-format porcelain to a waterproof backer and mount it on a patented mechanical track, allowing a full surround to be installed in a day without thinset or grout. Regal designs, kits, and ships its systems from the Cleveland area, pairing the products with hands-on factory training and technical support.
