All Wet

Illustration: "Water" (1793), William Blake

I see a lot of ads for walk-in bathtubs. These tubs have a little door that you are supposed to open, walk in and sit down. In theory, the closed door is sealed so the tub won't leak when you fill it. These seem to be aimed at seniors (and perhaps people with disabilities).

You're going to have to sit there (maybe in a cold bathroom) while the tub fills. Then, when you've finished your bath, you've got to wait (wet and possibly shivering) while the tub drains, before you can open the door and leave. This does not seem like a good idea. I have seen at least one brand that claims to have a fast-draining system and a heated seat so you won't get chilled while waiting. They suggest "multi tasking" by rinsing (won't that add more water?) while draining.

A more practical solution to bathing for the mobility-impaired is a walk-in shower with a chair or stool and a hand-held spray. This lets you get in and out quickly and does not require prolonged standing. For those who really can't stand or walk, there are shower/commode wheelchairs designed to roll into a shower or perch over a toilet.
