Tub Drain Dam

This Idea was inspired by [TomP]'s "Toe Sprayer", and is a much simpler alternative.

This device is a gadget that plugs into a bathtub drain-hole, but it has a drain-hole in it. Think of it as a simple piece of flexible tubing just big enough in diameter to tightly fit in the tub-drain. A mere centimeter-or-so of its length sticks above the tub-floor.

Now when you take a shower, the tub can't drain until enough water collects (that is, a centimeter-or-so of water depth) to go over the top if the tubing/"dam" and thence down the drain.

Your toes, of course, can get a thorough soaking in that "reservoir" of water while you wash the rest of your body under the shower.

When done --or almost done-- you simply pull the tubing out of the drain hole, let the shallow reservoir empty, and rinse your feet. The way they brag about how various soaps can lift dirt right off of whatever-you-want-to-clean, and assuming you use that sort of soap, then you might now indeed be done cleaning yourself, including the toes.
