TOTO Aquia IV Toilets in Canada

The Aquia IV is the dual-flush model in TOTO's range, and the one people choose when they want the fixture to look clean and modern as well as work well. The skirted body hides the trapway, so the outside is a smooth sweep with no ridges to trap dust behind the bowl.

What makes it different
  • Dual flush, 1.28 / 0.9 GPF — a full flush and a reduced one on the same toilet. Over a household's year that difference is real, and it is the main reason to pick the Aquia over a single-flush model.
  • Skirted design — no exposed trapway. Better looking, and far quicker to wipe down.
  • One-piece or two-piece — the Aquia IV comes both ways, which is unusual. See one-piece and two-piece.
  • Height — Regular Height, or Universal Height, which sits closer to chair height. Our guide to standard versus universal height covers which suits which household.
  • WASHLET+ versions — bowls built to conceal a bidet seat's supply line, and complete units already paired with a WASHLET — C2, C5, S2, S5, S7 and S7A.
Measure your rough-in before ordering

Measure from the finished wall to the centre of the bolts at the base of your current toilet. Twelve inches is standard in Canada; 10 inches needs a toilet built for it. This cannot be corrected after delivery — the rough-in size guide shows how to take the measurement.
