24 x 36 inch sink/shower stall, smart jon is removable to give more room to shower. Drained by pumping the water from the bottom to a shower water storage tank with 12v pump. Most of the stuff in my van was purchase on Amazon, links to the items are on my web site http://tgfoto.com/camp.html Also our blog is on our web site. As of this writing the shower water is ran through that orange pump sitting there, it's put in to the kitchen sink that is full of warm water. The high roof transit van allows for standing in the shower. If you're 5'7" of so.
