We have a half bath off of kitchen. This is the location we had our cats litter box. My wife and I really cannot stand cleaning the box so we looked into alternatives to make living fulltime in are camper easier. Ordered the catgenie with a dome. Installed a pex tee with a ball valve to shut the water supply off when necessary and drilled a hole in the sink drain plumbing just below the vent to intall a threaded 90° elbow for the catgenie drain. The threaded 90° was spun in and I used JBweld white waterweld to seal it to the abs drain pipe. We did drill a small hole in the face of the vanity cabinet to feed the water supply and drain line through for appearance. 120v power cord is plugged in to a brown extension cord and is tucked away around the window box and isn't really noticeable. We hardly ever have to touch this litter box other than changing a sanitizer/deodorizer cartridge and adding some plastic litter to it. If you have a cat and hate dealing with the mess this could be a option for you. There are 4 things needed: Space, its kind of big- water supply-a drain and a 120v recepticle nearby.
