Choosing a TOTO One-Piece Toilet

A TOTO one-piece toilet has an integrated ceramic tank and bowl. Compare the exact model number, dimensions, flush volume and included seat before ordering: one-piece construction alone does not determine bowl height, footprint or bidet-seat compatibility.

Start with the installation

• Rough-in: measure from the finished wall to the centre of the floor drain. Check the model's specification sheet and any separately required adapter.
• Room size: compare the full projection and width, plus the clearances needed around the toilet. A one-piece toilet is not automatically shorter than a two-piece model.
• Height and bowl shape: check the actual dimensions, whether the bowl is elongated or round, and the finished seat height.
• What is included: confirm the seat, installation fittings and any optional bidet equipment in the selected listing.

Which model should I compare?

Browse the available UltraMax, UltraMax II, Aquia IV, Carlyle II, Legato and Nexus configurations below. These are model families: flush volume, seat package and connection details can differ between versions. Drake is a two-piece toilet family; compare it in our TOTO two-piece toilet collection.

Can I add a TOTO WASHLET?

A WASHLET is an electronic bidet seat. WASHLET+ uses a compatible toilet and seat designed to conceal the supply connections. Confirm both model numbers and the installation requirements before choosing a combination. A WASHLET+ connection does not mean a bidet seat is included.

Does every model have the same warranty?

No blanket five-year warranty applies to this collection. Check the manufacturer's warranty for the exact toilet and any electronic seat; terms and coverage may differ. Ask Golzar Home to confirm the documentation for your selection.

Shop online or contact our Vaughan showroom with your rough-in measurement, room dimensions and preferred features. Confirm current availability and delivery timing for the selected item before scheduling installation.
