A built-in foaming soap dispenser can clear a countertop and make handwashing or dishwashing more convenient, but the fit and refill setup matter as much as the foam. The picks below include three dispensers designed to produce foam and two conventional built-in soap dispensers for shoppers who would rather use regular liquid soap. Check your counter thickness and the space under your sink before choosing.

Our Picks: Best Built In Foaming Soap Dispenser For Kitchen Sink reviews
1. Bchunlucve: A Foaming Pump with a Large Refillable Bottle
The Bchunlucve is a built-in pump made to dispense foam directly from the nozzle. Its under-counter bottle keeps the sink deck clear, and the included 22-ounce capacity is a practical advantage if your household uses soap often.
The dispenser has stainless steel construction and is described as suitable for kitchen or bathroom use. For foaming, the listed mixing guidance is three parts liquid or gel soap to seven parts water. Users also report that the pump head rotates a full turn and that two tubes are included for different countertop thicknesses. Those details may help with positioning, though it is still wise to check the hardware and clearance against your own sink.
Compared with the other foaming choices here, its stated bottle capacity makes it the clearest option for shoppers who want fewer refills. The main trade-off is that you must prepare diluted soap rather than simply pouring in standard-strength soap. The listed dimensions also make checking your available under-sink space worthwhile.
Pros:
- Dispenses foam with each press
- Includes a 22-ounce refillable bottle with a wide opening
- Stainless steel construction suits kitchen or bathroom use
- Two tube options are reported to help with different counter thicknesses
Cons:
- Requires diluted soap for foaming
- Check under-sink clearance and installation fit before buying
Verdict: Choose the Bchunlucve if you want a built-in foaming pump with a clearly stated, generous bottle capacity and are comfortable mixing soap with water.
2. HAIOLORPRO: A Foaming Dispenser with Two Tube Options
This HAIOLORPRO model is an under-counter dispenser designed to make foam with each press. Its main installation feature is a pair of spiral tubes: the shorter option is listed for surfaces up to 1.57 inches thick, while the longer one is listed for surfaces up to 3.15 inches. The longer tube also needs enough room below the counter.
The pump bottle has a wide opening, and the product description highlights rubber gaskets and a reinforced nut intended to help keep the mounting stable and limit leaks. The bottle’s exact capacity is not stated in the supplied product details, so shoppers comparing refill intervals should not assume it holds as much as the Bchunlucve’s listed 22-ounce bottle.
Everyday experiences appear mixed: some users find installation straightforward, while others report a stiff or catching pump action and a stream that can travel across the sink. If you choose this model, consider where the nozzle points and whether the pump will be comfortable for everyone who uses it.
Pros:
- Designed to dispense foam in one press
- Includes two tube lengths for different counter thicknesses
- Wide-mouth bottle is designed for easier refilling
- Gaskets and a reinforced nut are included in the leak-protection design
Cons:
- Some users report a stiff or catching pump action
- Soap may project across the sink depending on nozzle direction
Verdict: The HAIOLORPRO is worth considering when the two mounting lengths suit your counter, but the reported pump feel makes it a less certain pick for households that prefer a light, smooth press.
3. COLAYERIST: A Flexible-Fit Foam Pump for Kitchen or Bath
The COLAYERIST is another built-in pump intended to create foam with each press. It comes with short and long spiral tube options. The product description lists the shorter tube for surfaces up to 1.57 inches thick and the longer one for surfaces up to 3.15 inches, with adequate under-sink clearance needed for the longer option.
The wide-mouth bottle is designed to make refilling easier, and the dispenser is described as suitable for dish soap, hand soap, and bath soap. The suggested mixture is three parts liquid or gel soap to seven parts water. As with any built-in dispenser, confirm the included mounting parts can be installed in your counter before starting; one user with a thick surface reported that installation was not possible with the hardware they had.
Some users find it works much like a typical built-in sink pump while producing foam, and one person described a workaround for installing it behind a deep sink. That does not guarantee an easy fit in every setup, especially where access below the sink is tight. Compared with the Bchunlucve, the COLAYERIST has more clearly described tube-fit ranges, while the Bchunlucve lists its bottle capacity.
Pros:
- Designed to dispense foam directly
- Two spiral tube lengths accommodate different listed surface thicknesses
- Wide bottle opening helps simplify refilling
- Can be used with several types of liquid soap when diluted as directed
Cons:
- Installation fit may be a concern on some thick counters
- Requires a soap-and-water mixture for foaming
Verdict: Consider the COLAYERIST if its listed tube lengths match your counter and you want a foaming dispenser, but verify the mounting setup before ordering.
4. GAGALIFE: A Top-Refill Dispenser for Regular Liquid Soap
This GAGALIFE model is not a foaming dispenser. It is a built-in pump for regular liquid soap, lotion, or detergent, with a 17-ounce bottle that refills from the top. That top-refill setup can be more convenient than reaching under the sink, but it does not offer the direct foam dispensing that the first three picks are designed for.
The brushed-nickel model is made from ABS plastic, and the pump head swivels to meet different angles of use. The manufacturer says it fits sink holes from 1 to 1.5 inches in diameter and surfaces up to 2.17 inches thick. Confirm both measurements before purchasing, since a compatible hole and counter thickness are essential for a built-in installation.
Users often describe the installation as quick and the appearance as a good fit for the sink area. For anyone who specifically wants foam, however, this is a different kind of product: it dispenses liquid soap rather than converting it to foam.
Pros:
- Top-refill design avoids routine refilling under the sink
- 17-ounce bottle holds liquid soap or detergent
- Swiveling pump head allows different dispensing angles
- Listed hole and counter-thickness limits help shoppers check fit
Cons:
- Dispenses regular liquid, not foam
- Only fits within the stated sink-hole and surface-thickness limits
Verdict: Pick this GAGALIFE if convenient top refills matter more than foam; skip it if a foaming pump is a must-have.
5. GAGALIFE with Extension Tube: Draw Soap from a Larger Bottle
This GAGALIFE set is a conventional liquid soap dispenser, not a foaming pump. Its key difference is a 40-inch food-grade silicone tube that connects the dispenser to a larger soap bottle under the sink. Instead of refilling a small attached reservoir, you can use a compatible full-size bottle as the supply.
The pump head is described as brushed nickel brass, and the kit includes two bottle stoppers intended to fit a range of bottle necks. Its longer tube can reduce the need to refill a built-in reservoir, but you will need space below the sink for the soap bottle and a clear route for the tube. The set includes installation instructions, and users commonly find the setup manageable.
Compared with the top-refill GAGALIFE model, this one shifts the refill work below the sink and uses an external bottle. That may suit a busy kitchen, but it is not the right choice if you want a compact foaming setup or do not have room for a soap container in the cabinet.
Pros:
- 40-inch tube draws soap from a larger bottle
- Brass pump head with a brushed-nickel finish
- Includes two stoppers for different bottle necks
- Designed for DIY installation with instructions included
Cons:
- Dispenses regular liquid soap rather than foam
- Requires room under the sink for the soap bottle and tubing
Verdict: Choose this set if you want a built-in liquid soap pump supplied by a larger bottle; for direct foam dispensing, choose one of the first three products instead.
How to Choose a Built-In Foaming Soap Dispenser
Check Whether You Want Foam or Regular Liquid Soap
A foaming dispenser is built to create foam as you pump, while a standard sink dispenser delivers liquid soap. The first three products in this guide are presented as foaming pumps; the two GAGALIFE options are for regular liquid soap. Choose based on how you want soap to come out, not just on the dispenser’s built-in appearance.
Measure the Counter and Sink Hole
Measure the thickness of the counter where the dispenser will sit, and check the diameter of the existing hole if you plan to use one. The HAIOLORPRO and COLAYERIST list two tube lengths with maximum surface thicknesses, while the GAGALIFE top-refill model states both a hole-size range and a surface-thickness limit. Do not assume one model’s mounting parts will fit another model’s requirements.
Look at the Space Under the Sink
Built-in pumps use hardware and, in most cases, a bottle or tube below the counter. Check for plumbing, drawers, disposal equipment, and storage that could block installation or bottle access. The longer mounting tubes on some models require enough clearance below the sink, and an extension-tube kit needs room for its separate soap bottle.
Consider the Soap Mix and Refill Routine
Foaming dispensers may need diluted soap rather than soap straight from the bottle. The Bchunlucve and COLAYERIST descriptions specify a three-to-seven ratio of soap to water. Follow the instructions for the dispenser you select rather than assuming every pump uses the same mix. If you prefer not to dilute soap, a conventional liquid dispenser may be a better match.
Compare Bottle Capacity and Refill Access
A larger bottle can mean fewer refills, but bottle capacity is not listed for every pick. The Bchunlucve includes a stated 22-ounce bottle, and the top-refill GAGALIFE has a stated 17-ounce bottle. A top-refill design lets you add soap from above, while an extension tube draws from a larger bottle below the sink. Think about which refill method is easiest in your kitchen.
Think About Pump Feel and Nozzle Direction
The pump should be comfortable to press and should direct soap into the sink or onto your hands without splashing. One HAIOLORPRO user experience points to a pump that can feel stiff or catch, along with a stream that may travel across the sink. These reports are a reason to pay attention to nozzle placement and return options when comparing products.
Frequently Asked Questions
Do built-in foaming soap dispensers use regular dish soap?
Some are designed to use liquid or gel soap mixed with water. The Bchunlucve and COLAYERIST descriptions give a three-parts-soap-to-seven-parts-water ratio. Check the instructions for your chosen dispenser before filling it.
Can I use a regular liquid soap dispenser to make foam?
No. A conventional liquid dispenser, such as either GAGALIFE model here, delivers liquid soap rather than creating foam. Choose a product specifically described as a foaming dispenser if foam is your priority.
How do I know whether a dispenser will fit my countertop?
Measure the counter thickness where the pump will mount and check the hole diameter. Compare those measurements with the product’s stated limits and tube options. Also make sure you can reach the mounting hardware from below.
Will a built-in dispenser fit beside any kitchen sink?
Not necessarily. The dispenser needs a suitable mounting hole or a surface that can be drilled, plus enough under-sink space for its bottle and hardware. Plumbing and other items in the cabinet may also limit where it can go.
Which pick has the largest stated bottle capacity?
The Bchunlucve includes a 22-ounce bottle. The top-refill GAGALIFE lists a 17-ounce bottle. Capacity is not stated in the supplied details for the other dispensers.
Are the GAGALIFE models foaming dispensers?
No. Both GAGALIFE products in this guide are intended for regular liquid soap. One has a top-refill bottle; the other uses an extension tube to draw soap from a larger bottle.
Final Recommendation
For a true built-in foaming pump, the Bchunlucve is the most straightforward choice if you value a stated 22-ounce bottle and are willing to dilute soap. The HAIOLORPRO and COLAYERIST offer two tube lengths for different counter setups, but careful fit checks matter, and the HAIOLORPRO has some reports of a stiff pump. If foam is not essential, the GAGALIFE top-refill model offers a simpler refill routine, while its extension-tube counterpart can draw from a larger bottle below the sink.
