I want to optimize space in my shop. The tank of a commode adds an additional foot to the size of the bathroom in the place where I want it located. I intend to be ADA compliant with this bathroom so that it will fit a wheelchair. After some research, I found a Japanese toilet that has the tank embedded in the wall. The bowl is mounted to the wall and it leaves a very clean look. A narrow sink and waterless urinal (not shown) complete the outfit.
