What is a commode chair used for? A commode chair, known in British English simply as a commode, is a type of chair used by someone who needs help going to the toilet due to illness, injury or disability. A commode chair sometimes has wheels to allow easy transport to the bathroom or shower. A toilet is a fixed bathroom fixture used for the disposal of human waste. It's typically made of ceramic and is a permanent part of modern bathrooms. On the other hand, a commode can refer to a portable toilet or a chair with a container underneath, used for the same purpose but is more versatile and movable. price model may vary, depends on availability call and check
