I need to add a second toilet in the same bath room.
Instead of buying a condo costing $100,000 for second bathroom and second (not needed bedroom). Our one bathroom condo has a large sink/cabinet, regular toilet, a shower stall good size and a whirl pool (tub size). Have any of you plumbers out there heard of using the shower as a second place to install a toilet ,changing out the doors to double hinged for privacy. I need help before the flooring goes down. Does the sewage need to go to a special spot? Also we have neighbors below us. Any ideas would be helpful!
