One-Piece Toilets

This collection covers one-piece toilets from Duravit, DXV and Toto. It includes Duravit DuraStyle and ME by Starck dual-flush and rimless elongated models, DXV St. George, Cossu and Modulus chair-height toilets with seats, and Toto Eco Soiree, Eco Guinevere and NEOREST one-piece toilets with 0.8 to 1.32 gallon flushes.

Measure the rough-in distance from the finished wall to the flange center, usually 12 inches, before ordering. Decide between elongated and round bowls and standard or chair height for comfort and accessibility. Check the flush volume against local requirements, whether a seat is included, and whether the model needs electrical power.

A one-piece toilet has the tank and bowl cast as a single piece, so there is no tank-to-bowl gasket or bolts to leak, and the smooth sides are easier to clean than a two-piece model. The trade-off is weight: a one-piece toilet is heavier to carry and set.

Frequently asked questions

What rough-in do I need for a one-piece toilet?

Measure from the finished wall to the center of the floor flange. Most homes use a 12 inch rough-in; check the rough-in listed on each toilet before ordering.

Is a seat included?

It depends on the model. Several DXV toilets include a seat; check each listing title and description.

What does gpf mean?

Gallons per flush. WaterSense toilets use 1.28 gpf or less, and dual-flush models offer a lower flush for liquids.
