Collection: TOTO One-Piece Toilets

TOTO's one-piece toilets: Ultramax and Ultramax Low Profile, Redington, Aurora, Soirée, Promenade II and the dual-flush Aquia IV, in elongated and round bowls.

One-piece means the tank and bowl are cast as a single piece of vitreous china. There is no seam to clean between them and no tank-to-bowl gasket to fail, which is why it is the usual choice for a primary bathroom. The trade-offs are weight — they are awkward to carry upstairs alone — and that damage to either half means replacing the whole fixture.

Most are offered in both 1.28 GPF (WaterSense) and 1.6 GPF, and in Universal Height, TOTO's chair-height bowl that sits roughly two inches taller than a regular-height one and is easier on the knees. Models listed as WASHLET+ Connection are built to hide the supply line for a TOTO bidet seat; those usually ship Less Seat, so the WASHLET is a separate order.

Measure your rough-in before you order — finished wall to the centre of the closet bolts, 12" standard. Free Ontario delivery.
