Big decisions!

We start our attic renovation tomorrow at 7:30am! But we have some major decisions to make in the next few days. The first: which toilet!?! I want a concealed trapway (see how they all have smooth sides, you don't see the outline of the waste pipe nor is there a little shelf for hair and dust to collect on?), comfort height toilet.

The Studio: round bowl, I like that it is dual flush.

 The Town Square: elongated bowl, I like the fancy business on the front of the base.

 The Tropic: elongated bowl, one piece toilet. The internet says one piece is better because it is easier to keep clean. Not sure I care.

Which toilet do you prefer?
