Should you choose TOTO Aimes or Aquia IV?

Aquia IV is the broader and cheaper range by a clear margin. It has 20 models against four, it can be bought bare from $1,089, and at every washlet tier it undercuts Aimes by $366 to $393.

The functional difference is the flush. Aimes gives you one button and 1.28 gallons. Aquia IV gives you two, 1.28 for solids and 0.9 for liquids.

Whether that saves water depends on the household actually using the smaller button. If it does, an Aquia IV will average under a gallon per flush. If it does not, the two are equivalent.

Aquia IV also offers Arc and Cube styling variants and both one-piece and two-piece construction. Aimes is one-piece in a single design.

What Aimes offers is simplicity. Four models, all one-piece, all with the seat already fitted, so there is very little to decide beyond which washlet tier you want.

For most buyers the Aquia IV is the better value. Choose Aimes if you specifically want its look and are happy to pay for the smaller, simpler range.
