Swiss Madison Avancer review (2026)
- Integrated tankless smart toilet — heated seat, warm-water bidet, dryer, and touchless flush in one unit
- Priced roughly $700–$1,000, a fraction of premium Japanese smart toilets
- Standard 12-inch rough-in; needs a grounded GFCI outlet nearby
- Best-loved features: warm seat and instant warm water; weakest: the air dryer
A sleek, tankless one-piece smart toilet that packs heated-seat, warm-water bidet, and touchless flushing into a price most luxury Japanese brands can't touch.
Style-conscious buyers who want a fully integrated smart toilet — heated seat, warm-water bidet, touchless flush, night light — without paying $4,000+ for a Toto Washlet or Kohler Numi. Best for a 12-inch rough-in bathroom that already has (or can easily add) a grounded outlet near the toilet.
Features & performance
Tankless dual Vortex flush (1.1/1.6 GPF)
A direct water-line, tankless design with a cyclonic dual-flush — 1.1 gallons for liquids, 1.6 for solids — that keeps the bowl clean while sipping water. The tankless body is what gives it that low-profile, modern look.
Warm-water bidet with heated seat and dryer
Adjustable front and rear wash with on-demand warm water (temperature, pressure, and nozzle position all adjustable), plus a heated seat that warms instantly and a self-cleaning nozzle. A warm-air dryer is included, though it's the unit's slowest feature.
Touchless and hands-free flushing
Flush by standing up (auto off-seat), waving over the foot sensor, or using the wireless remote. A 9V battery backup lets you flush during a power outage, so a blackout never leaves the toilet unusable.
LED night light and remote control
A built-in night light gently illuminates the bowl for middle-of-the-night trips, and an included wireless remote controls wash, dryer, seat heat, and water settings — no fumbling for buttons in the dark.
Pros
- Integrated smart-toilet features (heated seat, warm-water bidet, dryer, night light, touchless flush) at hundreds less than premium brands
- Clean tankless one-piece silhouette that looks high-end and is easier to wipe down
- Genuinely warm seat and instant-on warm water, not a tepid reservoir
- Multiple flush options including hands-free auto and foot sensor, with a battery backup for power outages
Cons
- Warm-air dryer is widely called slow and weak — most owners still reach for paper
- Needs a nearby GFCI outlet; if you don't have one, budget for an electrician
- Big elongated footprint won't suit tight or small bathrooms
- Newer brand without the decades-long reliability track record of Toto or Kohler
What owners say
Owners praise
- Owners call it a "game changer" and rave that the seat is warm instantly and the rinse water is warm and adjustable — comfort that feels far above the price
- Many highlight the all-in-one value: heated seat, warm-water wash, night light, and self-cleaning nozzle for hundreds less than premium brands
- Several report straightforward installation (once an outlet is in place) and like the clean, modern tankless look
Common complaints
- The air dryer is the most common gripe — reviewers say it's slow and weak, taking several minutes and leaving most people reaching for paper anyway
- Some note the electrical requirement caught them off guard and they had to arrange a GFCI outlet before they could use it
- A few wish the dryer had stronger speed/heat settings
Who it's for
Buy it if: Buyers who want the full integrated smart-toilet experience — warm seat, warm-water bidet, touchless flush, night light — on a realistic budget, and who have a standard 12-inch rough-in plus a grounded outlet (or are willing to add one). It's ideal for a style upgrade where the warm-water comfort and clean tankless look matter more than having the absolute strongest dryer on the market.
Skip it if: Skip it if you rely heavily on the air dryer to go truly paper-free — premium models dry far better. Also skip if your bathroom can't fit a roughly 27-inch-deep elongated bowl, if you have no way to add a GFCI outlet near the toilet, or if you specifically want the multi-decade reliability record of a Toto or Kohler and are willing to pay several times more for it.
Alternatives to consider
- TOTO Washlet S550e (with compatible bowl). The luxury benchmark — auto open/close lid, EWATER+ electrolyzed self-cleaning, premium air deodorizer and a far better dryer. Costs several times more and the seat is often sold separately from the bowl, but it's the reliability and performance leader.
- Swiss Madison Plaisir Smart Toilet (B0DVH8SJ1F). Same brand, step up in convenience — adds automatic lid open/close and an LED display on top of the bidet, auto flush, and foot sensor. Worth comparing if hands-free lid operation is a must-have for you.
Our verdict
Frequently asked questions
Is the Swiss Madison Avancer a full smart toilet or just a bidet seat?
It's a fully integrated smart toilet — the tankless one-piece bowl and the bidet electronics are built into a single unit. You're not adding a seat to an existing toilet; you replace the whole fixture. The heated seat, warm-water wash, dryer, night light, and touchless flush all come built in.
Do I need an electrical outlet to use it?
Yes. The bidet, heated seat, dryer, and electronics need a grounded GFCI outlet (standard 120V) near the toilet. There's a 9V battery backup so you can still flush during a power outage, but the smart features won't run on battery. If you don't have an outlet nearby, plan for an electrician before installing.
How does it compare to a Toto Washlet?
The Avancer covers the same core experience — warm seat, warm-water bidet, touchless flush — for a fraction of the price. Where Toto pulls ahead is in extras and refinement: a stronger dryer, advanced self-cleaning like EWATER+, and a long, proven reliability record. If you want luxury-grade performance and don't mind paying several times more, go Toto; if you want the smart-toilet essentials and great value, the Avancer makes the case.
