Should you choose TOTO Aimes or Carlyle II?
These two are as close as TOTO one-piece ranges get. Both are skirted, both flush 1.28 gallons with TORNADO FLUSH, both use CEFIONTECT glaze and both sit at universal ADA height.
The practical difference is price and availability. Carlyle II can be bought as a plain toilet at $1,145; Aimes cannot be bought without a washlet at all.
At matched washlet tiers Carlyle II is cheaper throughout: $239 less at S2, $275 at S5, $419 at S7 and $426 at S7A.
That is a real gap for two toilets with the same specification, so it is worth looking at both in photographs. The shapes differ in profile and tank proportion even though the numbers match.
Unless you specifically prefer the look of the Aimes, the Carlyle II is the more sensible buy. Same flush, same glaze, same height, less money.
