Wave, Press or Pump Through the Sink Deck? Best Soap Dispenser Styles Compared

As an Amazon Associate, we earn from qualifying purchases. This doesn’t change our recommendations or the price you pay.

The best soap dispenser depends on where it sits and how you use it. A touchless sensor model keeps messy hands off the pump while you cook, a sink-mounted pump clears the counter, and a refillable foaming bottle stretches a jug of hand soap. They solve different problems, and the listings describe them in different terms.

We compared six dispensers sold by Amazon.com or the brand’s own Amazon store, all in stock when we checked: two touchless sensor pumps, a built-in sink dispenser, two countertop pumps and a two-pack of foaming bottles. For each, we quote capacity, power source, dispensing controls and warranty exactly as the listing gives them, and we flag the gaps, such as a missing capacity or an empty weight field.

Any germ or hygiene claim below belongs to the brand, not to us. A dispenser only delivers the soap; the washing still does the work.

1. simplehuman Liquid Sensor Pump, 9 oz: Best Overall Touchless

simplehuman’s Liquid Sensor Pump is a countertop dispenser that releases liquid soap when a motion sensor sees your hand under the spout. Nothing has to be pressed, so the pump stays clean while your hands are covered in raw chicken or garden dirt. simplehuman markets it as “touchless, germ-free,” saying clean hands stay clean and dirty hands don’t spread germs; treat that as the brand’s pitch, not a measured result.

Dosing works by distance. The listing says to hold your hand close for a little soap and farther away for more, so there are no buttons or dials to set. A precision nozzle is meant to stop cleanly between dispenses, which simplehuman says keeps the counter free of soap residue and sticky rings.

Power comes from a built-in rechargeable battery rather than disposable cells. A magnetic charging puck attaches to the pump, and the brand says one charge lasts up to three months. The body is high-grade brushed stainless steel that simplehuman says resists rust, fingerprints and water spots, and the listing gives it an IP67 rating for easy cleaning. It holds 9 ounces and measures 4.4 x 2.8 x 6.4 inches at 0.88 pounds, per the specs.

It suits a busy kitchen sink or a shared family bathroom where the pump gets used dozens of times a day and nobody wants to buy AA batteries. The listing says it pairs with simplehuman’s own liquid hand soap, though it doesn’t say other liquid soaps won’t work.

Why we like it

• No batteries to buy
• Distance-based dosing
• IP67-rated stainless body

Watch out for

At 9 ounces it needs refilling more often than the 17-ounce PZOTRUF, and the warranty field is empty.

2. Moen 3942SRS Kitchen Soap Dispenser: Best Built-In Sink Dispenser

Moen’s 3942SRS is a built-in kitchen soap dispenser: the pump head sits on the sink deck, and an 18-ounce bottle hangs below the counter. Amazon files it under Built In Soap Dispensers, the type that uses a spare hole, often the one left over from an old sprayer, so the pump looks like part of the faucet set.

Refilling is done from above. The listing says the top lifts off the pump so you can pour more soap into the bottle without crawling under the sink. Moen says it can hold either soap or lotion, which makes it useful at a bar sink or laundry sink as well as the main kitchen sink.

The finish is Moen’s Spot Resist Stainless, which the brand says resists fingerprints and water spots, and Moen says it coordinates with its other stainless products. Installation is described only as “hassle-free”; the listing doesn’t give the mounting hole diameter or the maximum countertop thickness, so check both against your sink before you order. The warranty field reads “Limited lifetime warranty,” matching the bullet about Moen’s Limited Lifetime Warranty.

It suits kitchens where a soap bottle on the ledge always looks cluttered, and owners pairing it with a stainless Moen faucet. Renters should ask before drilling or reusing a sink hole.

Why we like it

• Biggest stated bottle
• Refills from the top
• Stated lifetime warranty

Watch out for

Confirm your sink has a usable hole and check the hole size with Moen before buying, since the listing skips it.

3. OXO Good Grips Stainless Steel Soap Dispenser: Best Countertop Pump

OXO’s Good Grips Stainless Steel Countertop Soap Dispenser is a straightforward pump bottle built around the brand’s focus on easy handling. The listing says it was designed with busy cooks in mind, so you can pump soap with one hand and move on to the next step of a recipe.

Two features make that possible. A nonslip base holds the dispenser in place, so it doesn’t skate across the counter when you press down. The pump head is soft and cushioned, and OXO says the spout is angled for pumping soap onto a sponge, into your hands or into the sink.

Refills are simple. A clear window at the base shows how much soap is left, and a wide mouth with a MAX fill line helps you pour without overfilling. The body is brushed stainless steel that OXO calls fingerprint-proof. The specs list it at 3 x 3.5 x 7.5 inches and 0.33 pounds. The listing doesn’t state the capacity in ounces, so check the box or OXO’s site if volume matters.

It suits kitchen sinks where the dispenser does double duty for hand soap and dish soap, and bathrooms where a heavy, tippy bottle has been a nuisance. No batteries, no charging and nothing to program.

Why we like it

• Stays put while pumping
• See-through level window
• Nothing to charge

Watch out for

The listing never gives a capacity, so you can’t compare volume against the other picks.

4. Casabella Sink Sider Solo: Best Pump and Sponge Caddy

Casabella’s Sink Sider Solo combines a soap pump with a sponge caddy, so the two things you reach for when hand-washing dishes share one footprint by the sink. The listing calls it a 2-in-1 dishwashing solution and includes a sponge so you can start right away.

In daily use you press the pump to put soap straight onto the sponge with one hand, then drop the sponge back into the caddy. Casabella says the open-top caddy lets wet sponges or scrub brushes dry more efficiently, which keeps the area tidier than a sponge left flat on the counter.

Refilling is a matter of pulling a tab up to remove the pump and pouring soap into the wide-opening bottle. The pump also comes off the base for cleaning. Casabella lists the size as 5.75 x 4.75 x 9.25 inches with a 14.5-fluid-ounce reservoir, and the specs give 0.65 pounds. The brand suggests it for kitchens, bathrooms and laundry rooms.

It suits people who wash dishes by hand every night, small kitchens without a sink caddy, and anyone tired of a soggy sponge sitting in a puddle. If you only need hand soap at a bathroom sink, the caddy is extra bulk.

Why we like it

• Sponge storage built in
• Removable pump
• 14.5 fl oz reservoir

Watch out for

It takes more counter space than any other pick, and its sales rank trails the rest.

5. PZOTRUF Automatic Soap Dispenser, 17 oz: Best Large-Capacity Touchless

PZOTRUF’s Automatic Soap Dispenser is a battery-powered touchless pump with a large, clear reservoir. An infrared sensor detects your hand within 0 to 2.36 inches of the spout, according to the listing, and releases soap without contact. PZOTRUF notes that hands or light-colored objects work best with the sensor.

The 17-ounce (500 ml) tank has a wide opening and a transparent body, so you can see the level and know when to refill. Output is adjustable in five levels using “+/-” buttons, from a small drop to a full dose, and the brand says the no-drip spout minimizes clogging. If no liquid comes out, the listing says to clean the nozzle promptly.

The body is brushed aluminum that PZOTRUF calls non-rust, with IPX4 waterproofing and a sealing ring meant to keep soap and water away from the circuit board. A non-slip base keeps it in place. It runs on four AA alkaline batteries, which aren’t included, so it doesn’t need an outlet. The specs list it at 6.37 x 3.34 x 7.4 inches; the weight field is empty.

It suits a kitchen or family bathroom where a small dispenser runs dry every few days. It also works anywhere without a nearby outlet, since there’s no charger.

Why we like it

• Big see-through tank
• Five output settings
• Strong sales rank

Watch out for

Budget for AA batteries, and note the listing gives no warranty terms.

6. UUJOLY Foaming Soap Dispenser, 2-Pack: Best Refillable Foaming Bottles

UUJOLY’s Foaming Soap Dispenser is a pair of refillable 15-ounce plastic pump bottles that turn diluted liquid soap into foam. The brand’s pitch is economy: add water to your soap at a ratio of 1 part soap to 3 to 5 parts water, and the foaming pump whips it into lather, so a bottle of regular hand soap goes further.

Use is simple. Fill with your soap-and-water mix, screw the pump back on, and press. The listing explains that a plastic safety buckle sits between the pump top and the screw cap for shipping; remove it and the plunger moves freely. The pump head is plastic and reusable.

The bottles are made of PETG, which UUJOLY describes as high quality and not easy to break, a sensible choice for a tub ledge or a child’s bathroom. Each measures 2.64 x 2.64 x 7.48 inches. The brand suggests them for kitchens, bathrooms and laundry rooms, and for shower gel and shampoo as well as hand soap. The model and weight fields are empty in the specs.

They suit households that buy hand soap by the jug, anyone who likes the feel of foam, and homes that want matching bottles at two sinks. The listing we checked is the amber version.

Why we like it

• Two bottles per pack
• Stretches liquid soap
• Shatter-resistant plastic

Watch out for

Foaming pumps need thin, diluted soap; thick gel soap poured in straight may not foam well.

How We Chose the Best Soap Dispensers

Every pick was in stock and sold by Amazon.com or the brand’s own Amazon store when we checked. From there, we compared what each listing actually states:

• Dispensing style: touchless sensor, manual countertop pump, built-in sink pump or foaming pump.
• Capacity: ounces as listed, and a flag where the listing omits it.
• Power and controls: rechargeable or AA batteries, adjustable output, sensor range.
• Refilling and cleaning: wide mouths, lift-off tops, level windows and removable pumps.
• Warranty and popularity: the warranty field, seller and Amazon sales rank.

We kept one product per brand and skipped listings from sellers we couldn’t tie to the brand.

Soap Dispenser Buying Guide

Best Automatic Soap Dispenser: Rechargeable or AA?

Both touchless picks use a sensor under the spout, but they power it differently. The simplehuman pump has a built-in battery and a magnetic charging puck, and the brand says a charge lasts up to three months. The PZOTRUF runs on four AA alkaline batteries that you buy separately. Rechargeable means no battery runs; AA power means you can set it anywhere and swap cells in seconds.

Best Touchless Soap Dispenser: Dosing and Sensor Range

Adjustable output keeps a touchless pump from dumping too much soap. simplehuman varies the dose by how far your hand is from the sensor, while PZOTRUF uses five button-set levels and lists a detection range of 0 to 2.36 inches. If you share the sink with kids, a fixed button setting is easier to keep consistent.

Best Kitchen Sink Soap Dispenser

At the kitchen sink you have three options. A built-in dispenser like the Moen 3942SRS hides an 18-ounce bottle under the counter and frees up the ledge, but it needs a spare hole; if you’re replacing a faucet anyway, our guide to the best kitchen faucet covers models with matching finishes. A countertop pump like the OXO needs no installation. The Casabella Sink Sider Solo adds a sponge caddy for hand-washing dishes.

Best Foaming Soap Dispenser

Foaming pumps mix air into diluted soap. UUJOLY suggests 1 part soap to 3 to 5 parts water, which stretches a bottle of liquid soap. Don’t pour thick liquid soap into a foaming pump undiluted, and don’t put foaming mix into a liquid pump; each pump is built for its own consistency.

Best Refillable Soap Dispenser: Capacity and Refills

Stated capacities among our picks run from 9 ounces (simplehuman) to 18 ounces (Moen), with Casabella at 14.5, UUJOLY at 15 per bottle and PZOTRUF at 17. OXO doesn’t list one. Bigger tanks mean fewer refills, but a wide mouth or lift-off top matters just as much: OXO and PZOTRUF list wide openings, Moen fills from above, and Casabella’s pump pulls out.

Matching the Bathroom Sink

In a bathroom, footprint and finish usually matter more than capacity. A slim bottle like the UUJOLY or OXO leaves room on a small vanity, and stainless or brushed finishes hide water spots. Pair it with a matching holder from our best toothbrush holder guide, and if you’re redoing the whole vanity, see our best bathroom sink picks.

Handwashing Basics and a Drier Sink Area

The dispenser is only the start. The CDC’s handwashing page lists five steps: wet your hands with clean, running water, apply soap, lather the backs of your hands, between your fingers and under your nails, scrub for at least 20 seconds, rinse well and dry with a clean towel or air dryer. It also notes that if soap and water aren’t readily available, a hand sanitizer with at least 60% alcohol is the fallback.

Soap drips on a counter or floor are slippery, so wipe them up, and check a built-in dispenser’s bottle under the sink now and then for leaks onto the cabinet floor. Touchless and no-drip claims on these listings are the brands’ own descriptions, not something we measured.

Frequently Asked Questions

What is the best soap dispenser for most homes?

The simplehuman Liquid Sensor Pump is our top overall pick. It’s touchless, rechargeable with up to three months per charge per simplehuman, lists an IP67 rating and is sold by Amazon.com. For a lower-cost touchless option, the PZOTRUF has the best sales rank among our picks.

What is the best automatic soap dispenser that doesn’t need batteries?

The simplehuman Liquid Sensor Pump uses a built-in rechargeable battery and a magnetic charging puck instead of disposable batteries. The PZOTRUF, our other touchless pick, needs four AA alkaline batteries that aren’t included.

Do touchless soap dispensers kill germs?

No dispenser washes your hands for you. simplehuman markets its pump as “touchless, germ-free,” meaning you don’t touch the pump, but that’s a brand claim. The CDC’s handwashing steps, including scrubbing for at least 20 seconds, are what matter.

Can I put regular liquid soap in a foaming dispenser?

Dilute it first. UUJOLY recommends a ratio of 1 part soap to 3 to 5 parts water for its foaming bottles. Thick, undiluted soap may not foam properly in a foaming pump.

How do I install a built-in kitchen sink soap dispenser?

A built-in dispenser like the Moen 3942SRS drops through a spare hole in the sink or countertop, with the bottle hanging below. Moen’s listing doesn’t state the hole size, so check the installation sheet or Moen’s site against your sink before buying.

The Bottom Line

For most kitchens and baths, the simplehuman Liquid Sensor Pump is the best soap dispenser: touchless, rechargeable and stainless. The PZOTRUF gives you a bigger touchless tank on AA batteries, the Moen 3942SRS hides 18 ounces under the sink with a stated lifetime warranty, and the OXO Good Grips is the simple one-handed pump. Hand-wash dishes nightly? The Casabella Sink Sider Solo keeps soap and sponge together, and the UUJOLY two-pack turns bulk liquid soap into foam.
