HI! We just bought a house! But we hate the toilets. Probably 20 years old, same as the house. They seem to use a lot of water and do a poor job flushing...So I want to replace them.

Looking at the toto drake 2 and the AS champion 4.

Have a couple questions:
1. Our half bath is small. The front of the current toilet is about 26.5" from the wall. This led me to the smaller AS Champion 4 Round version, but the schematic looks like its 28.5" (the same size as the toto drake 2?). Is this the case? Can anyone recommend a great toilet that will fit into the current space?

2. Will I want to use the same toilet throughout the house for aesthetic purposes? I was hoping to use elongated toilets in the other 2 full baths.
