: Hi I have a comercial toilet in my apartment, that uses a Sloan Flushometer. My problem is this, I am trying to replace the bowl. The bowl has a rough in size of 8 3/4. Is there any manufacturers that make a bowl that small in the back?? I am wondering if it was originally 10" and the previous owner of the apartment added tile changing the dimension of the rough in. Currently there is a crane toilet, and no local dealers carry that brand. Any Ideas????
