My toilet rough-in is 13.5 inches. I purchased a Toto Drake and it looks there will be a 3.125 inch space from the wall to the tank, which doesn't look good. Does anyone know if I would be able to use a Toto Vespin with the 14" unifit instead? How much room would there be from the tank to the wall? Are there any other choices? Thanks for your help.
