it is limited on the wall i have. plus its already built out. all i have to do is pull the moulding. stand is already built to size, all is cut to size, plumbing is in place. plus i like the size. its 24 deep which is about as deep as im willing to go (to reach bottom, im in up to my pits, literally), 5 ft across the front (no 6 footer but not 4 either) and 18 inches front to back. i wouldnt mind 24 inches to the back, but to make it that deep, i have to pull down the new walls and doors i built in the back room and build them again. that would make that room smaller.
