I wanted to make the most comfortable bathroom as possible using natural marble and keeping bright. It has the water heater controls. There are two led eyeball cans, as well as an led fan light combo. The fan is connected to automatic moisture sensor, and lights are on a motion sensor. I also put the shower mixer outside actual shower, just cause I have a 7 yr old son and every time I bath him and lean in to turn on the water, i get blasted. The compost toilet can be switched easily, this model is off-grid so it can go anywhere. All water in the Haus is hooked up to gray water drainage system. I built this bathroom the way I’d like it, I hope you do too.
