A bath chair is a special chair that you can use to sit in when you take a bath. It's different from a regular chair because it's made specifically for taking a bath, and it's designed to keep you safe and comfortable in the tub.
The bath chair typically has a seat and a backrest, and sometimes it also has armrests or a footrest. It's usually made of plastic or metal, and it's designed to be waterproof, so it won't get damaged when you use it in the bathtub.
The bath chair usually sits on the bottom of the tub, and it has suction cups on the bottom that help it stay in place. You sit in the chair while you take a bath, and you can use it to help you stay upright and balanced while you wash yourself.
The bath chair is a great tool for people who have trouble sitting in the bathtub or who are at risk of falling while taking a bath. It can help you stay safe and comfortable, and it can make bathing much easier and more enjoyable.
