Hi, I am trying to install a new Toilet on a slab in a remodel. I would like to put the toilet on a diagonal to the corner but it would require a narrow tank and a 10" rough in to fit (closet flange is already set). Looks like a Toto CST412MF.1 would work (15 3/8 wide on 10" rough in)..... are there other toilets that would work that would be less money? Thanks
