Hi volks, kind of an off-season upgrade, but I just finished putting in a hot shower setup in my westy.  This is my 2nd one of these, and I think I have it dialed in now.  A great compromise between space, cost, simplicity, and convenience.

I posted pics at the bottom of this samba forum post.  Let me know what you think.

I used a solenoid valve to control temperature and heat the water tank from the rear heater hoses and fits perfectly under the rear seat.  I may have to take a trip to Baja and check it out.

P.S. I know I didn't invent new anything here, I have seen other shower setups, but none with this simple of an installation.
