A good tub seat should be designed to resist rusting, be durable and should be an appropriate size. The shower seat needs to fit inside the tub, while also being wide enough and tall enough for the user to sit in, according to Wal-Mart.
Tub or shower seats are chairs intended to provide the users a place to sit while washing themselves in the shower. A tub seat helps elderly individuals who have trouble standing for long enough to shower. These seats are also a good idea for those recovering from surgery, such as a knee replacement. Those recovering from knee surgery may want to look for a chair that also has a foot stool to elevate the leg, according to Mayo Clinic.
Tub chairs are made with molded plastic or coated steel and feature rubber tips to keep the chair from slipping in the shower, according to Just Home Medical. Adjustable legs are an added plus that allows users to set the height to their specific needs. Most tub seats support individuals up to 250 pounds, but there are bariatric chairs available with higher weight limits.
Chairs can have solid plastic or cushioned seats. The seats are usually made with drainage holes to allow water to pass through easily and keep the user clean. Some chairs have arm rests and removable arm rests, which may make it easier to stand after a shower.
