Getting in and out of the bath can be quite a balancing act for any of us. A bath and shower board is a secure bench over the bath, that you can sit on while you swing your legs in, before settling down into the water to stretch out and soak. Or you use it to sit over your bath to wash, or as a seat if you have an over bath shower. Being able to sit can greatly reduce your chance of slipping over.
This bath board has locking brackets and is easily adjusted to fit the majority of baths safely. See the video below.
