A shower chair is a type of chair designed for use in a shower or bathtub. It is typically made of plastic or metal and has a seat and backrest, as well as armrests and sometimes a footrest. The chair is designed to provide support and stability while bathing, and may be height adjustable. Some models feature drainage holes or slats to allow water to pass through, while others are waterproof and can be used outside of the shower. Shower chairs are often used by people with limited mobility or those recovering from an injury or surgery.
