Bathtubs and showers are generally designed based on the existing locations of plumbing connections and drains in residential, commercial, and institutional bathrooms. Bathtub and shower doors and shower pans help trap and drain water and protect against damage to walls and floor. Faucet systems and panels mount to walls and include showerheads and temperature controls. Bathtub spouts and fillers deliver hot and cold water to bathtubs. Fixed and handheld showerheads enhance the showering experience. Bathtub and shower repair parts are used to repair or replace worn, lost, or damaged parts.
