I purchased a walk-in tub for my grandma, and it has been one of the best investments I have made since I started taking care of her. My grandma has very limited health problems, but she complains about aging, and how sometimes it just hurts to get around.
She uses a cane for walking, but often has problems bending at the knees. Simple tasks like sitting down, standing up, or lifting a leg over the bathtub are a real challenge for her. Unfortunately, not only is it physically challenging for my grandma, but it has also caused emotional distress. She gets upset with herself because she is not physically able to do things easily anymore.
