I'm pretty sure that the Ultramax (standard height) is the toilet that I want but it is not available with CEFIONTECT in bone. The Carlyle is the skirted version of the Ultramax and it is available with Sanagaloss in bone. I'm in Canada and the price for the Carlyle is about $140 more than the Ultramax. Is the CEFIONTECT worth the extra money? I don't understand why CEFIONTECT isn't available on more toilets.
