Best Toilet and Bidet Bundle Deals of 2026

The Drake II and S500e Washlet represent TOTO's most proven pairing: the toilet holds a verified MaP score of 1,000 grams and uses just 1.28 GPF, while the Washlet adds on-demand warm water wash, warm air drying, ewater+ pre-mist, and a heated seat -- all controlled by a wired remote.

The Drake II has been a contractor favorite for over a decade. Its siphon jet flushing action and 2.125-inch fully glazed trapway channel waste cleanly without the partial clogs that plague narrower passageways. Published MaP test data at map-testing.com confirms the 1,000-gram maximum score across multiple test years, making it one of the most consistently verified toilets in any price range.

The S500e Washlet pairs naturally. Its instantaneous water heating eliminates the waiting that older tank-based washlets required, and the ewater+ electrolyzed water pre-mist coats the bowl before every use, reducing the adhesion of waste. Aggregated owner reviews consistently cite the warm air dryer and adjustable wand position as the features that convert first-time users into permanent bidet converts.

The Aquia IV adds a dual-flush system on top of TOTO's proven siphon-jet platform, making it the best water-saving bundle in this list -- its 0.8/1.0 GPF dual flush has been independently verified to achieve 1,000 grams on the full flush by MaP testing.

California Title 20 regulations and similar state-level water restrictions have made 0.8 GPF toilets increasingly important for homeowners in drought-prone areas. The Aquia IV qualifies for many municipal water rebate programs because it exceeds EPA WaterSense requirements at both flush volumes. See our guide on best dual flush toilets for a full comparison of dual-flush mechanisms across brands.

The C200 Washlet is a mid-range seat that delivers the core washlet functions without the premium features of the S500e. Its heated seat and wired remote panel will satisfy most users who are new to bidet seats. The tank reservoir holds roughly a liter of pre-heated water, which is adequate for a single wash cycle in most use cases.

Kohler's Highline Classic is one of the most widely installed toilets in North America, and pairing it with the C3-230 bidet seat creates a reliable, easily serviced bundle backed by Kohler's one-year limited warranty on both pieces.

The Highline Classic's 800-gram MaP score is solid but noticeably below the Drake II's 1,000-gram certification. For typical household use, 800 grams is more than adequate -- MaP testing guidelines classify any score above 500 grams as sufficient for residential use. The shortfall only matters to buyers with specific concerns about heavy-use or waste-heavy flushing performance.

The C3-230 bidet seat is Kohler's mid-tier offering. It covers the core functions: adjustable water temperature, adjustable nozzle position, heated seat, and slow-close lid. What it does not include -- warm air drying -- is a feature that pushes some buyers toward TOTO's Washlet line instead. For users comfortable with minimal toilet paper for drying, the C3-230 is a fully functional and competitively priced seat.

The Champion 4's 4-inch flush valve and 2.375-inch fully glazed trapway -- the largest trapway diameter on this list -- combined with the Brondell Swash 1400's full electronic bidet functions, creates a bundle specifically suited to high-demand bathrooms where clog avoidance is the top priority.

The Champion 4's 4-inch wide flush valve moves 70% more water in the initial flush surge compared to standard 2-inch valves. Combined with the 2.375-inch trapway, this creates what American Standard describes as the widest waste channel in its residential lineup. Published MaP results confirm 1,000 grams, placing it at the ceiling of certified performance despite the slightly older 1.6 GPF water volume. For buyers in households where the toilet regularly handles heavy waste loads, this specification difference is meaningful. Learn more about clog-resistant design in our guide to no-clog toilets.

The Brondell Swash 1400 is an independent bidet seat that fits American Standard's elongated bowl dimensions reliably. It offers stainless steel nozzles, dual wash modes, warm air drying, and a night light function. While Brondell and American Standard are separate companies, the Swash 1400 has strong compatibility documentation for the Champion 4 bowl geometry, and Brondell maintains a dedicated compatibility chart on their support site.

The Woodbridge T-0001's dual-flush operation and clean-skirted design offer a modern aesthetic at an accessible price point, and the Bio Bidet BB-600 delivers core electronic bidet functions -- warm water, heated seat, and remote control -- to complete a capable entry-level bundle.

Woodbridge entered the North American market as a direct-to-consumer brand and has gained traction among buyers who prioritize design over brand legacy. The T-0001's skirted bowl hides the trapway entirely, giving it a sleek modern appearance that is typically only found at higher price points. Its MaP-certified 1,000-gram flush score at dual-flush operation is a verified result, not a marketing claim, which places it in the same performance tier as toilets at significantly higher prices.

The Bio Bidet BB-600 fills out the bundle competently. Its three wash modes (posterior, vortex, and feminine), adjustable water temperature, and wireless remote cover the core bidet functions. The seat's nozzle self-cleaning function reduces maintenance requirements. For buyers transitioning from toilet paper for the first time, the BB-600 provides the features most likely to make that transition comfortable and permanent.

The UltraMax II's seamless one-piece body combined with the S550e Washlet's auto-open and auto-close lid creates a cohesive, near-automatic experience that approaches smart toilet functionality at a fraction of a fully integrated unit's cost.

The UltraMax II's one-piece construction eliminates the hardware joint between tank and bowl that is the most common site for leaks in two-piece toilets. Its lower profile also makes it easier to clean around the base. For master bathrooms where aesthetics matter as much as function, the seamless silhouette of the UltraMax II is a significant design advantage. For a full comparison of the two designs, see our article on best flushing one-piece toilets.

The S550e is TOTO's flagship Washlet seat and the top-of-range model in this roundup. Its proximity sensor detects when a user approaches and automatically opens the lid -- and closes it after departure. The integrated deodorizer runs continuously while seated, and the pre-mist function ensures the bowl surface is wetted before use, which TOTO's internal data shows reduces bowl staining between cleanings. Aggregated owner reviews routinely cite the S550e as the product that most changes daily bathroom habits, largely due to the auto-open function eliminating the last manual step in the process.

The Swiss Madison Ivy's contemporary skirted design pairs with the Luxe Neo 320's non-electric dual-nozzle bidet attachment to create the only fully non-electric bundle on this list -- no outlet, no installation permit, and no electricity cost required.

Many bathrooms in older homes and apartments were built without an outlet near the toilet, and running new electrical service is expensive. The Swiss Madison Ivy + Luxe Neo 320 combination bypasses that problem entirely. The Luxe Neo 320 bidet attachment runs entirely on household water pressure, with a dual nozzle (posterior and feminine) and a pressure adjustment dial. Water temperature is ambient -- cold in winter, slightly warmer in summer -- which is the primary comfort trade-off versus electric seats.

Swiss Madison has published EPA WaterSense certification for the Ivy at its 1.1 GPF flush volume, making it eligible for municipal water rebates in cities including Los Angeles, Phoenix, and Las Vegas. The 800-gram MaP score is adequate for residential use. For renters, the combination of a non-invasive bidet attachment and a water-efficient toilet creates a meaningful bathroom upgrade without any lease-violating modifications. Our Swiss Madison toilet guide covers the full range of their certified models.
