I think you need to decide if you just want to get cleaned off, in which case the shower would be enough, or if you have pain and want to use it to help ease your pain, in which case the walk in tub could help do that. I'm thinking my friend said she got some help (from medicare?) on the cost. If you're wanting one, check with medicare and your doctor before you get one. She also said hers fills and drains real quick. She starts drying her arms and goes from there by the time she gets to her legs its empty.
