If you are in your forever home, and want to make sure you are able to stay living at home as you get older, a walkin shower is an excellent idea. Unless there are young children in the home who still need a bathtub, you can replace a tub with a walk in or roll in shower to retain your independence as long as possible. Most people in older communities are replacing bathtubs with a step in or barrier free shower while they still have a choice.
