TOTO オーロラ vs アクアIV

Should you choose TOTO Aurora or Aquia IV?

Both are skirted one-piece-capable ranges with CEFIONTECT glaze and universal ADA height, so the daily experience is comparable.

The choice is between a single flush that is always 1.0 gallons and a dual flush that is 1.28 or 0.9 depending on the button.

An Aurora 1G uses 1.0 gallons every time with no decision to make. An Aquia IV uses 0.9 on the light setting and 1.28 on the full one, so its real average depends on how the household uses it.

Aquia IV is the broader range by a wide margin: 20 models against four, in one-piece and two-piece, with Arc and Cube styling variants and a lower entry price of $1,089.

Aurora is four models, one-piece only, and its washlet versions let you choose the seat tier at checkout rather than listing each combination.

Choose Aurora if you want a guaranteed 1.0 gallon flush and prefer a single button. Choose Aquia IV if you want more configurations, a styling variant, or a lower entry price.
