D-tub Shower

Showering off before getting in a tub is the most sanitary way to use a hot tub.  Also, rinsing off after getting out of the tub is nice to wash the chlorine out of your hair, not to mention that it, too, is a pleasing part of the cleansing ritual.

The D-tub has a full-size hot shower base, 48" x 30", a 100 gallon fresh water tank, and 60 gallon grey water.  Underneath the shower is the biodiesel-powered heater, which should provide some radiant floor heating.  There is also a small sit-down changing area, as well as a dry location to place clothes and towel hangers.

The hot shower water will be is powered from a 12 gallon marine hot water heater, with the heater glycol loop (heated by the biodiesel heater) running through the shower hot water heater.

There will also be a three-way valve so that users can shower with chlorinated tub water, just in case we run out of fresh water, to insure that a sanitary tub is maintained as long as there is water in the system.
