It did not fit over the top of a Glacier Bay toilet that has buttons on top of the tank. We took the legs back off and wall mounted it since it had to be attached to the wall anyways because it is so rickety. If you have a narrow space you can’t screw in the bottom brace as it is two long screws in from each side. Instructions are not intuitive - I installed Part E incorrectly twice because of the bad graphics. Screws for cam locks don’t have receivers in the MDF so they wobble and chew it up - I would suggest adding glue or more screws to the unit. Finished product had no stickers or plugs to cover cams and nothing to cover the wall bracket holes so I think I will take some melamine from the legs and glue it on as finish trim.
