WOODBRIDGE B0970S Smart Tankless Toilet Review: Bidet, Heated Seat, and Tankless Power Flush in One Minimalist Package

The WOODBRIDGE B0970S is an integrated smart bidet toilet that folds a warm-water wash, a heated seat, a warm air dryer, and a tankless power flush into a single skirted one-piece body. It targets buyers who want the function of a Japanese-style washlet without bolting a separate seat onto an existing bowl. Our take reflects manufacturer specifications, retailer listings, and patterns owners report, not a hands-on plumbing test.

WOODBRIDGE has built its reputation on feature-dense fixtures that undercut premium Japanese brands, and the B0970S sits near the top of that lineup. If you are weighing the wider catalog first, our Woodbridge brand guide maps how the smart models differ from the company's standard gravity toilets.

What the WOODBRIDGE B0970S actually is

Physically, the B0970S is an elongated, one-piece toilet with a fully skirted trapway and no visible tank. The seat is molded into the unit and carries the electronics, so there is no aftermarket seat to buy. Seat height measures 17.3 inches from floor to seat, which lands inside the 17 to 19 inch ADA comfort-height range and reads as chair height for most adults.

Everything runs on mains electricity. The manufacturer lists a 110 to 120 volt, 50 to 60 Hz supply, so the toilet needs a nearby GFCI outlet. A 9 volt battery backup, sold separately, allows a manual flush during a power outage. Control is handled through an integrated multi-function remote, side buttons, and a foot sensor that triggers the flush without a handle.

Because it is tankless, the B0970S has no refill cycle to wait on and no tank sweating to manage in humid bathrooms. The trade-off is that it depends on line pressure and electricity rather than stored water, which shapes both its strengths and its limits.

How the tankless power flush works

Instead of dropping stored tank water into the bowl, the B0970S draws water directly from the supply line and drives it with a built-in booster pump. That pump is the reason a tankless toilet can flush hard without a large gravity head above the bowl. WOODBRIDGE positions the pump specifically to hold flush strength steady where household pressure is low or inconsistent.

The flush is a dual system rated at 1.6 gallons per flush for the full flush and 1.0 gallon for the reduced flush, which the manufacturer averages to 1.28 gallons per flush. That 1.6 gallon full flush matches the federal maximum for toilets, so the B0970S is not the ultra-lean 1.28 gallon single-flush design you find on many gravity models. If the difference matters to your water bill or code, our breakdown of 1.28 GPF vs 1.6 GPF explains what each number does in real use.

Pressure is the one spec to check before buying. The manufacturer lists a minimum dynamic water pressure of 0.07 MPa for correct operation. Homes on very weak wells or old, undersized supply lines should confirm they clear that floor, because a tankless bowl cannot fall back on a reservoir of stored water the way a gravity tank can.

WOODBRIDGE does not publish a MaP flush score for the B0970S, and we do not assign one it has not been given. MaP testing measures how many grams of solid waste a flush clears in a single cycle, and it is the cleanest way to compare bulk-clearing power across gravity toilets. If that metric is new to you, our explainer on what a MaP score means shows why the number matters and where a published figure would normally appear.

Bidet, heated seat, and comfort features

The washlet side is where the B0970S earns its smart label. The self-cleaning wand delivers a posterior wash, a feminine wash, and a pulsating wash, with adjustable water pressure so the spray can be tuned from gentle to firm. Water temperature runs across six levels, from ambient up to a warm setting, and the wand retracts and rinses itself between uses.

Comfort features stack up around the wash. The seat is heated with six temperature levels, which is the single feature most owners cite for cold-climate bathrooms. A warm air dryer follows the wash so paper use drops, and an intelligent LED night light makes the bowl easy to find after dark without flipping on the overhead.

Odor control uses a lightless catalyst deodorizer that pulls air through a catalytic reaction rather than a scented cartridge you replace. Hygiene automation rounds it out with foot-sensor and automatic flushing, so hands never touch a handle. The remote consolidates wash, dry, seat, and flush controls in one place, which keeps the toilet itself visually clean and buttonless from the front.

On paperwork, the B0970S is certified by ICC-ES to ASME A112.4.2 / CSA B45.16 and ASME A112.19.2 / CSA B45.1, and listings note compliance with IPC, IRC, UPC, and NPC codes. WOODBRIDGE backs the unit with a one year limited warranty against defects in material and workmanship, which is shorter than the multi-year coverage on some standard ceramic toilets and worth factoring into a smart-electronics purchase.

WOODBRIDGE B0970S spec comparison

The table below places the B0970S next to its tank-equipped WOODBRIDGE sibling and two benchmark high-efficiency gravity toilets, so you can see the smart-versus-standard trade clearly. Every value is drawn from manufacturer or verified listing data.

The comparison makes the choice concrete. If raw, documented bulk-clearing power and water certification lead your list, the gravity benchmarks publish a 1,000 gram MaP score and carry WaterSense at 1.28 gallons. If a warm wash, heated seat, and dryer lead your list, the B0970S delivers a feature set those standard bowls cannot touch without an add-on seat. The tankless B0970S also differs from its own B0930S sibling by dropping the tank and the auto open-close lid in favor of a lower, more minimalist profile.

Pros and cons

• All-in-one washlet: warm-water bidet, heated seat, warm air dryer, and deodorizer are integrated, so there is no separate seat to source or wire.
• Booster-pump flush: the tankless pump is designed to hold flush strength where household pressure is low or uneven.
• Minimalist one-piece form: the skirted, tankless body is easy to wipe down and reads clean in small or modern bathrooms.
• Chair-height and ADA-range seat: 17.3 inches suits most adults and easier sit-to-stand movement.
• Hands-free hygiene: foot-sensor and automatic flushing plus a self-cleaning wand reduce touch points.
• Pressure dependent: a tankless bowl needs the manufacturer minimum dynamic pressure and has no stored water to fall back on.
• Needs power: a GFCI outlet is required, and outage flushing relies on a separately sold 9 volt battery.
• No published MaP and 1.6 gallon full flush: the full flush is not WaterSense-lean, and there is no MaP figure to compare bulk clearing head to head.
• One year limited warranty: shorter than the coverage on many standard ceramic toilets.

Who should buy the WOODBRIDGE B0970S

The B0970S makes sense for buyers who specifically want a full washlet experience in one fixture and have a bathroom with a nearby outlet and normal household water pressure. If you have wanted a heated seat, a warm-water wash, and a dryer but do not want to shop for a compatible aftermarket bidet seat, this consolidates all of it into a single unit with a clean, tankless look.

It is a weaker fit for a few situations. Homes on marginal well pressure should confirm they clear the dynamic pressure minimum first, since the tankless design cannot rely on stored water. Buyers whose top priority is a documented, maximum bulk-clearing gravity flush with WaterSense certification will be better served by a standard high-efficiency bowl, and our roundup of the best flushing toilets covers those gravity options in depth.

For everyone else, the pitch is straightforward. You are paying for integrated comfort and hygiene automation, not for a record-setting flush spec, and the B0970S is built around that priority. If it matches your bathroom and pressure, it is one of the more complete smart bidet toilets in the WOODBRIDGE range.
