In this guide
simplehuman's Liquid Sensor Pump in the 9 fl. oz. size is the company's rechargeable, touch-free soap dispenser for a bathroom or kitchen sink. The brushed stainless steel version is $70 direct from simplehuman, matte black, white, brass, polished, matte gold and oiled bronze are $80, and a Katie Merz artist edition is $90. At research time the brushed unit was marked as shipping the same day with free delivery.
The design brief is short and the engineering claims are specific: a tubing pump that pushes soap through an airtight tube in a fraction of a second, a silicone valve that closes the spout between uses, a sensor that reads hand distance to decide how much to pour, and a housing sealed well enough to rinse. simplehuman rates the mechanism for 150,000 cycles and one charge for up to four months. Those numbers are why it costs $70, and whether they matter rests on how hard your sink gets used.
Our verdict
A well-engineered sensor pump for a kitchen or bathroom sink that gets heavy use, with a charge interval measured in months and a cycle rating measured in years; overkill for a guest bath, and its long-term happiness depends on refilling with thin, gel-type soap.
- A good fit for
- A household that washes hands at the same sink many times a day, hates the crusted nozzle of a manual pump, and would use the four-month charge interval to forget the thing exists.
- We would skip it if
- You want to run thick or foaming soap through it, you dislike charging anything in a bathroom, or $70 for a soap dispenser sounds absurd no matter how it is built.
Reasons to consider it
- Rated for 150,000 dispense cycles, with a warranty of two years from simplehuman
- Charge interval quoted at up to four months, using an included charging puck; 3–4 hours to full
- Dispense volume set by hand distance, a silicone valve against drips, and a waterproof body you can rinse
The compromises
- simplehuman steers you to its own liquid soap for best performance, at $12 a bottle on the same page
- The battery is built in, so when it eventually fades the pump goes with it; simplehuman does not list a replacement
- The 9 oz. reservoir is the small one; the 14 oz. version costs $120 and the caddy version $100
What we have not verified: The pump was not filled for this piece. Whether dish soap or thicker third-party liquids clog it, how loud the motor is, and how the sensor behaves in bright sunlight were not assessed. simplehuman's spec list says four months per charge while its own product description says three; the four-month figure is the one in the specifications and in the feature copy.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.

Liquid Sensor Pump, 9 oz., Brushed Stainless Steel
A 150,000-cycle rating, a months-long charge interval with an included puck, variable dispense by hand distance, a drip-stopping silicone valve and a wide refill opening, all in a rinsable stainless body at $70 in brushed.
Before you buy: Built-in battery with no listed replacement, a strong nudge toward simplehuman's own $12 soap, and a 9 oz. tank that a large household will refill often.
Price checked September 11, 2026. Retailer prices can change.A tubing pump, a silicone valve, and a sensor that measures distance
Most cheap sensor dispensers use a small gear or diaphragm pump that dribbles after each shot and gums up when the soap dries. simplehuman's answer is a peristaltic-style tubing pump: soap is forced through a closed, airtight tube, the shot lands in a fraction of a second, and a silicone valve at the spout shuts so nothing hangs off the nozzle afterward. The company calls the tube clog-proof, which is marketing, but the mechanism is the reason it can put a 150,000-cycle figure on the page.
The other trick is variable dispense. Hold your hand close to the sensor window and you get a little soap; hold it farther away and you get more. There is no menu and no button for it. A wide refill opening under the lid takes a full bottle without a funnel, a QR code inside the lid reorders soap, and the housing is described as waterproof so the whole unit can be rinsed at the sink. It also runs hand sanitizer, which is thinner than soap and easier on the pump.
Four months per charge, from a puck, in three to four hours
Power comes from a built-in rechargeable cell that simplehuman rates at four months per charge in the specifications, with a charging port on the back of the unit. Charging is by an included puck that connects to the base; a white light pulses while charging and goes solid when full, which the FAQ puts at three to four hours. A solid red light means it is time to plug in. simplehuman's own description text on the same page says three months, so treat the interval as three to four months and expect less on a sink that runs all day.
The cell is not user-replaceable and simplehuman does not list a replacement on the page, so the pump's lifespan is the battery's lifespan. At 150,000 rated cycles and even 50 pumps a day, the mechanism is specified for around eight years; a sealed rechargeable cell recharged every few months will not be the first thing to wear out, but it will be the thing that ends it. The FAQ notes that the puck must sit logo-up to charge, and that the puck's adapter has to match its rating, which reads like the two support calls they get most.
Nine ounces, seven finishes, and what the extra sizes cost
The dimension drawing puts the pump at a width of 2.8 inches, 4.4 inches deep including the spout and 6.4 inches tall, or 7.0 by 11.2 by 16.3 cm. The 9 fl. oz. capacity is the smaller of simplehuman's two liquid sizes and the one the company labels as ideal for handwashing. Brushed stainless is $70, the six other plain finishes are $80, and the artist edition is $90. Adding UV-printed text and an icon costs $10 more, limits you to seven characters, and makes the unit final sale.
If 9 oz. sounds small for a kitchen, simplehuman's 14 oz. Liquid Sensor Pump is $120 in brushed, and a 9 oz. Sensor Pump Dish with a caddy for a sponge is $100. simplehuman's own liquid hand soap, which simplehuman says the pump is optimized for, is $12 a bottle in six scents on the same page. That soap nudge matters: simplehuman's coverage leaves out the contents themselves, and thick or foaming refills are the most likely way to make a tubing pump sulk.
Two years covered, thirty days to change your mind
The pump carries a warranty of two years, which simplehuman describes as covering manufacturing faults in ordinary home use, with the clock starting at purchase or delivery. The remedy is new or refurbished parts, an equivalent replacement, or merchandise credit if no equivalent exists, and a dated receipt plus photos or video of the defect may be requested. The exclusions are the ones to read for a soap pump: hard-water scale buildup, prolonged dampness, the soap itself, commercial use, and anything bought from third-party marketplace sellers on Amazon or eBay.
Returns are simpler. Anything bought direct from simplehuman.com qualifies for a refund in the month after receipt, return postage is covered through FedEx, and the refund takes up to 10 business days to appear. Personalized units are final sale, so add the engraving only after you have decided the pump belongs on your counter. Both policies are for US domestic orders; territories and APO addresses are excluded.
Skip it for a guest bathroom or a foaming soap habit
A sensor pump earns $70 when the sink is busy: a kitchen where hands get washed between raw chicken and the cutting board, or a family bathroom with three people brushing teeth at once. In a powder room used twice a week, a $12 bottle with a manual pump does the job and never needs a puck. The 150,000-cycle rating and the four-month charge are the entire case, and a low-traffic sink never cashes either one.
Walk away as well if your soap is foam. simplehuman sells a separate Sensor Pump Foam at $80 for that, and this liquid model is specified for gel-type liquid soap and sanitizer. And if the thought of one more rechargeable object in the bathroom bothers you, simplehuman's manual Pulse Pump is $50 with no sensor and no charging. The Liquid Sensor Pump is the right answer to a specific problem, and the problem is a sink that gets used a lot.
