We renovated a closet under the stairs into a powder room. The toilet has to go under the staircase part slighlty, but not all the way otherwise you'll hit your head. My question is am I restricted to the kind of toilet I can have because all the pipes will come out of the floor? Can I get a standard toilet with a water hookup under the tank on the left? Do I need a freestanding 1 pc toilet and tank? Do they make them so the pipes can run under the toilet? I know nothing, please advise. Thanks
