Need toilet and bidet and Aquia questions

Hi - Getting ready to put a new toilet and bidet in a new house - any suggestions? I love my toto promenade toilet but since it does not have a matching bidet we are looking at the Clayton's. Any feedback or other suggestios? We can't use the Carlyle because of the way the plumbing was roughed in.

Also - my daughter wants a dual flush and I see Aquia's I, II, and III. any differences??
Thanks

You want to match the Clayton bidet with the Promenade toilet or you are changing to a Clayton toilet and bidet?

Clayton is a "Traditional" looking 2 piece toilet (G-max flush)
Carlyle is a more "Contempory" 1 piece Skirted toilet (G-max)

If you are looking for a Traditional Non-skirted toilet with matching bidet than the Clayton is your best bet.

Aquia I is a Plastic p/trap Dual flush 15-1/4"
Aquia II is a China p/trap Dual flush 15-1/4"
Aquia III is a China p/trap Dual flush 16-1/8" (some cosmetic changes)
