Best Toilets With Heated Seat Included (Combo Units)

The Aquia IV and WASHLET+ S7 seat represents the highest-performing combination on this list, with a verified 1,000-gram MaP score, 1.0/0.8 GPF dual-flush operation certified by EPA WaterSense, and one of the most feature-rich heated seats sold in North America.

The Aquia IV uses TOTO's Tornado Flush technology, which replaces conventional rim holes with two nozzles that create a cyclonic rinse across the entire bowl surface. Owner reviews consistently note fewer cleaning sessions needed because the centrifugal water action prevents residue accumulation. The CEFIONTECT glaze, an ion-barrier ceramic treatment, further repels waste from bonding to the porcelain.

The WASHLET+ S7 seat connects to the Aquia IV through a shared supply line routed behind the fixture, eliminating the external T-valve most aftermarket bidet seats require. Seat surface temperature across the five settings spans from a gentle 82 degrees Fahrenheit up to 97 degrees, and the tank stores enough warm water to handle consecutive uses. The auto-open/close lid and auto-flush via remote add further convenience but are optional features buyers can ignore if they prefer manual operation.

The Drake II is among the most frequently sold toilets in North America, carrying a proven 1,000-gram MaP score and dual-flush operation at 1.28/0.9 GPF. Pairing it with TOTO's WASHLET+ C5 delivers three seat warmth levels, a warm-air dryer, and the hidden supply line integration that distinguishes WASHLET+ from standard WASHLET seats.

Drake II's Double Cyclone flushing -- two nozzles generating a continuous 360-degree rinse -- was TOTO's flagship residential technology before Tornado Flush arrived with newer models. In practice, the 1,000-gram MaP score tells the whole story: it removes the maximum test load in a single flush. Plumbers consistently recommend this model for households with heavy usage because the trapway and flush valve are overbuilt relative to most residential alternatives. See our TOTO Drake series guide for model comparisons across the full Drake lineup.

The WASHLET+ C5 seat covers the core heated-seat needs -- three surface temperature settings, oscillating and pulsating wash, adjustable water temperature, and a warm-air dryer. The remote or side-panel controls are intuitive, and owners with arthritis or reduced hand strength frequently cite the ease of operation as a significant plus. Seat power draw is approximately 540 watts during active wash, requiring a dedicated GFCI outlet.

The UltraMax II is TOTO's one-piece answer to the Drake II's flush power, carrying the same 1,000-gram MaP score in a single-unit form factor that is easier to clean around the base. The S500e seat adds eWater+ electrolyzed water misting, five warmth levels, and auto-open/close functionality.

One-piece toilets eliminate the gasket between tank and bowl that can harbor mildew in two-piece designs. Owner reviews for the UltraMax II consistently cite the cleaning ease as a standout benefit, and the Tornado Flush + CEFIONTECT glaze combination means the bowl surface resists staining between cleanings. The 1.0 GPF rating is among the lowest available while still achieving the maximum MaP score, which means long-term water savings are meaningful -- a household of four can save several thousand gallons annually compared to an older 1.6 GPF unit.

The S500e's eWater+ system uses electrolyzed water to mist the bowl before and after each use, suppressing odor-causing bacteria at the source. This feature, combined with the UV light sanitization of the wand, addresses the hygiene concerns some owners have about bidet wands. The auto-open lid -- triggered by proximity detection -- and auto-flush add true hands-free convenience. See our TOTO UltraMax series comparison for the full family breakdown.

The Woodbridge T-0001 is a modern one-piece toilet with dual-flush operation at 1.28/0.8 GPF and EPA WaterSense certification. Its bundled B0690S bidet seat offers three heated-seat levels, warm-water wash, and a dryer -- covering all the bases most users need.

The T-0001's skirted trapway design gives it a clean, modern aesthetic that costs significantly more in competing brands. The one-piece form means no exposed bolts at the tank base. Flush performance at 800 MaP grams is solid for most residential households -- the real-world difference between 800 and 1,000 grams becomes apparent only with very heavy or thick-material waste. For typical use, most owners report zero clogs over extended ownership periods.

The B0690S bidet seat uses an instant-heating system rather than a storage tank, which means no waiting for warm water but also a slightly higher peak electrical draw. The remote-control design is clean on the side panel, and the auto-close feature -- standard on this seat -- prevents the lid from crashing. At its price point, this is the combo that makes the most sense for guest bathrooms, rental properties, or cost-sensitive renovations.

The Kohler Veil is a fully integrated intelligent toilet -- the seat and toilet are one factory-assembled unit, not a pairing of two products. It offers dual-flush at 1.28/0.6 GPF, front and rear heated wash, adjustable seat warmth, night lighting, and Bluetooth connectivity for personalized user profiles.

The Veil's 600-gram MaP score is the primary tradeoff buyers must accept. For households with normal waste loads and no recurring clog issues with existing toilets, 600 grams is workable -- particularly since the ultra-low 0.6 GPF partial flush can be bypassed by using the full 1.28 GPF flush when needed. Households with known heavy-load situations or thick-material toilet paper should look at higher MaP options.

Where Kohler excels is the design execution and smart-home integration. The Konnect app stores up to six user profiles, each with personalized wash temperature, seat temperature, and water pressure preferences. The Veil is also available in several Kohler finishes beyond standard Cotton White, making it the choice for design-forward bathrooms where the toilet is a visual focal point.

Swiss Madison's Ivy series delivers a skirted-trapway profile with dual-flush at 1.28/0.8 GPF and EPA WaterSense certification. The bundled smart seat adds three heated warmth settings, rear and front wash, and a dryer -- a solid feature set at a price below most TOTO pairings.

Swiss Madison has positioned itself as the design-forward alternative to American Standard and Woodbridge, with cleaner lines and a European-influenced aesthetic that blends well in modern or minimalist bathrooms. The Ivy's skirted trapway removes the exposed curves at the toilet base that trap dust and grime, making floor cleaning easier. The 800-gram MaP score is appropriate for most residential households as long as thick or heavy toilet paper is not the household norm.

The smart seat's remote control operates seat temperature, water temperature, and pressure independently, with child settings reducing water pressure for smaller family members. Owners note that installation is straightforward -- about 30 to 45 minutes for most DIY-capable buyers -- because the seat ships pre-wired with a standard plug. The main risk noted in long-term reviews is inconsistent quality control on the bidet wand components, which is worth verifying at initial installation.

American Standard's Acticlean series features the brand's EverClean antimicrobial surface treatment and the Champion 4 flush system pedigree, producing a 1.28 GPF single-flush toilet with a 700-gram MaP score. The bundled heated seat offers three warmth levels but does not include a dryer -- a notable omission at this tier.

American Standard's comfort height dimension places the rim at 16.5 to 17 inches from the floor, matching standard chair seat height and meeting ADA guidelines for accessible design. For users with knee replacements, hip issues, or any condition affecting ease of rising from a seated position, this dimension matters practically every day. The EverClean surface is certified to inhibit bacterial growth on the china, which extends useful cleaning intervals.

The heated seat adds a meaningful comfort layer for users in cold climates or those with conditions like Raynaud's phenomenon, where cold surfaces cause discomfort. The absence of a dryer means users still need toilet paper for drying after wash use -- a minor but real limitation if the goal is fully reducing paper consumption. American Standard's service network is an advantage for buyers in smaller markets where TOTO or Kohler support may be less accessible. See our American Standard toilet reviews for the broader lineup.

The TOTO Nexus is a slim-profile one-piece toilet with a 1,000-gram MaP score at 1.28/0.9 GPF dual-flush and EPA WaterSense certification. The WASHLET+ C2 seat -- TOTO's entry-level WASHLET+ -- provides three heated-seat levels and warm-water wash, though it lacks a dryer, making it TOTO's most accessible combo price-wise.

The Nexus delivers TOTO's full flush technology -- Tornado Flush, CEFIONTECT glaze, 1,000-gram MaP -- in a body that sits noticeably lower and more compact than the UltraMax II. For bathrooms with limited clearance to the vanity or where the visual bulk of a taller tank is unwanted, the Nexus resolves that without sacrificing flush performance. The one-piece skirted design also makes floor cleaning easier than exposed two-piece trapways.

The C2 is TOTO's base WASHLET+ offering and provides the core heated-seat experience: three warmth settings, adjustable water temperature for the posterior wash wand, and soft-close lid. Users who find the dryer feature non-essential -- or who use it as a starting point before upgrading the seat later -- often cite the C2 as good value within the TOTO ecosystem. The WASHLET+ compatibility means upgrading to a C5 or S7 seat later is a direct swap with the same supply line connection.
