A solid surface shower pan is a waterproof, non-porous, one-piece molded acrylic or resin shower base that is installed as part of a shower system. It is a practical and durable alternative to traditional tiled shower floors. Solid surface shower pans are resistant to mold, mildew, and chemicals, making them a hygienic and easy-to-clean choice. They come in a variety of colors and styles, providing design flexibility. Historically, the development of solid surface materials in the 1960s revolutionized the shower industry, leading to the widespread adoption of these pans.
