I live in a 1954 house with original tile in the bathrooms (including wall tile 0, I had the tile sprayed white several years ago. Now, I'm needing to replace both toilets. They were installed in the early 1970's and one has a crack in between the tank and bowl, thus leaking. They are large though and the tile was not sprayed behind or underneath. I need to find a toilet that is larger or same size as current. Measurements areTank width=21.5", height=29", base=8" width, 12 "rough in. Any thoughts on a decent toilet that would cover this?
