The WASHLET+ AP is the only wall-hung pick in the pool. It includes the wall-hung elongated bowl, a WASHLET C5 bidet seat, and the DuoFit in-wall tank with dual-flush 0.9 and 1.28 GPF modes, so it bundles the parts that usually have to be sourced separately.

The Nexus is the second conventional two-piece floor-mount option, and its listing bundles an S7 Contemporary Bidet Seat rather than the S7A auto-flush seat.

How the picks were chosen
The pool for this article contains 3 complete TOTO WASHLET+ configurations, each listing a toilet and bidet seat combination. To shortlist, we kept only new, complete kits from an established maker, then compared the stated specifications: flush type, gallons per flush, bowl shape, piece configuration, wall-hung compatibility, and smart features. Prices on this page are read live from the store listing and can change. We did not test the units; every specification in this guide comes from the seller's listing or the maker's published product name.
Picking the right one for you
Flush type: dual flush versus single flush
All three picks state a flush volume of 1.28 GPF or lower. Two of the three list dual-flush modes: 1.28 gallons per flush for the full flush and 0.9 GPF for the reduced flush. The AP lists them as 0.9 and 1.28 GPF, while the Aquia lists them as 1.28 and 0.9 GPF. The Nexus listing mentions only a 1.28 GPF flush volume, so it does not state a reduced-flush mode. The EPA notes that WaterSense labeled toilets use 1.28 GPF or less while meeting performance criteria, and a dual-flush reduced mode can lower water use further for liquid waste.
Elongated bowls and clearances
Every pick here has an elongated bowl. Elongated bowls are common in current toilets, but they take more front-to-back space than round bowls. Before ordering, measure the bathroom clearances. If the space must meet accessibility standards, the ADA Standards set minimum requirements for newly designed and altered facilities; check the clear floor space and fixture sections of the standards for your project.
Wall-hung versus floor-mounted
The AP kit is the only wall-hung configuration in the pool. It includes a DuoFit in-wall tank, so the bowl hangs from a wall and the tank sits inside the wall. The Aquia and Nexus are two-piece floor-mounted toilets. Choose wall-hung only if the wall and plumbing can support an in-wall tank; otherwise a two-piece floor mount is the more conventional route.
Bidet seat and smart features
All three listings include a WASHLET bidet seat, but the seat models differ: the Aquia includes the S7A auto-flush seat, the AP includes the WASHLET C5, and the Nexus includes the S7 Contemporary Bidet Seat. The pool does not state power or water connection requirements for the seats. Ask the maker or your installer whether an outlet and water supply line need to be added before finalizing a kit.
WaterSense and efficiency
EPA's residential toilet page notes that toilets are by far the main source of water use in the home, accounting for nearly 30 percent of an average home's indoor water consumption. WaterSense labeled toilets are independently certified to use 1.28 GPF or less and meet EPA performance criteria. The listings here do not state a WaterSense label, so verify the label on the product box if it matters for a rebate.
Questions
What does GPF mean?
GPF stands for gallons per flush. Flush volumes listed in this guide are 1.28 GPF for full flush and 0.9 GPF for reduced flush on the dual-flush models. By comparison, the federal standard for new toilets is 1.6 GPF, and WaterSense labeled models use 1.28 GPF or less. A lower GPF means less water per flush, but performance also matters; WaterSense certification includes flush performance testing.
What is the difference between dual flush and single flush?
A dual-flush toilet has two modes: a full flush for solid waste and a reduced flush for liquid waste. In the Aquia and AP kits, the full flush is 1.28 GPF and the reduced flush is 0.9 GPF. The Nexus product name states 1.28 GPF and does not mention a reduced-flush mode, so the seller has not listed dual-flush operation for that model.
Do these toilets include bidet seats?
Yes. All three picks are WASHLET+ kits. The Aquia includes an auto-flush S7A seat, the AP includes a WASHLET C5, and the Nexus includes an S7 Contemporary Bidet Seat. The seller does not state the electrical or water connection requirements for these seats; confirm those before installation.
What should I check before choosing a wall-hung model?
The AP is the wall-hung pick and uses a DuoFit in-wall tank. This means the bowl is mounted to the wall and the tank is concealed inside it. You need a wall construction that can support the bowl, an in-wall tank, and plumbing access. A two-piece floor-mounted toilet like the Aquia or Nexus avoids that wall work.
Are these toilets WaterSense labeled?
The listings do not say WaterSense explicitly. They state flush volumes of 1.28 GPF, and the dual-flush models also list a 0.9 GPF reduced mode, which matches the efficiency level WaterSense targets. Independent certification is required for the WaterSense label. Check the product box or ask the seller for the label if you need it for rebates.
