Here is the inside of the shower vanity again. That little maple door swings open to allow access to the plumbing. I can get to the tank vent, shower sump discharge, shower plumbing, watermaker auxiliary tank float switch, (it shuts off the watermaker when full) and the wiring for the LectraSan control panel. Note that I didn't say I could get any work done. If anything more than tightening a hose clamp is needed, the panel the door is mounted on has to come out. Haven't had to do it,,,,yet.
