A drop-in whirlpool bathtub can add targeted water massage to a bathroom, but the right choice depends on more than jet count. You’ll also want to check the tub’s dimensions, drain location, step-over height, seating features, and any installation requirements. These five Kohler models offer different combinations of adjustable jets, comfort details, and heated surfaces; compare the listed specifications with your space before choosing.

Our Picks: Best Drop In Whirlpool Bathtub reviews
1. Kohler Devonshire: A Balanced 60-by-32-Inch Option
The Kohler Devonshire combines a familiar 60-by-32-inch footprint with eight adjustable whirlpool jets. You can control the flow and direction at each jet, so the massage is adjustable rather than fixed to one pattern. Its reversible drain may also give you more flexibility when planning the tub layout.
The comfort details include molded lumbar support, armrests, and a textured bottom surface. These features address different parts of the bathing experience: back support, a place to rest your arms, and added surface texture underfoot. The Devonshire collection connection may be useful if you’re coordinating other bathroom fixtures or products in the same style family.
Compared with the Archer, the Devonshire has a similar listed footprint and jet count but does not list the Archer’s 19-inch step-over height or slotted overflow. It’s a straightforward choice if those Archer-specific features are not priorities. Before ordering, confirm that the tub’s dimensions, drain setup, and installation needs work with your planned deck and plumbing.
Pros:
- Eight adjustable jets with controllable flow and direction
- Reversible drain offers layout flexibility
- Molded lumbar support, armrests, and textured bottom
- Listed 60-by-32-inch size makes it easier to compare with available space
Cons:
- No heated surface is listed for this model
- Does not list the Archer’s lower step-over design
Verdict: Choose the Devonshire if you want an eight-jet whirlpool with comfort features and a reversible drain in a listed 60-by-32-inch size.
2. Kohler Archer: Comfort Depth and a Slotted Overflow
The Kohler Archer is another 60-by-32-inch drop-in whirlpool with eight adjustable jets. As with the Devonshire, you can adjust each jet’s flow and direction. Its most distinctive listed feature is Comfort Depth: Kohler describes a 19-inch step-over height while retaining the depth of a standard 21-inch bath.
The Archer also has integral lumbar support and a slotted overflow. Those details may appeal if back support and the tub’s overflow design are part of your planning checklist. A textured bottom surface is included as well. These features make the Archer a more specialized alternative to the Devonshire, even though both share the same listed dimensions and jet count.
This model may suit a bathroom where a lower step-over height is a priority, but a 19-inch step-over is still a substantial step for some people. Check the product dimensions and installation documentation against your bathroom plan, and consider who will use the tub. The listing does not describe a heated surface, so look to the Archer with Bask if warming features matter to you.
Pros:
- Eight adjustable jets with individual flow and direction control
- Comfort Depth design lists a 19-inch step-over height
- Integral lumbar support and textured bottom
- Slotted overflow is a distinguishing design feature
Cons:
- The lower step-over is not the same as a low-entry or walk-in tub
- No heated surface is listed for this version
Verdict: The Archer is a strong fit if you want eight adjustable jets and the listed Comfort Depth design, especially if its step-over specification suits the people who will use it.
3. Kohler K-1124: A Basic Eight-Jet Acrylic Whirlpool
The Kohler K-1124 is a white acrylic drop-in whirlpool listed with eight jets and a drain. Its product information is much less detailed than that of the Devonshire, Archer, or Sunward, so it’s best viewed as a simpler option to investigate rather than a model with a clearly documented set of comfort extras.
The available description does not specify the tub’s dimensions, jet adjustability, drain position, support features, or step-over height. Those details can affect fit and daily use, so check the complete product listing and manufacturer documentation before making a decision. In particular, do not assume it shares the 60-by-32-inch footprint or reversible drain of the other Kohler models in this guide.
Its appeal is the core combination stated in the product title: an acrylic drop-in tub with eight jets and a drain. If you need detailed fit information or want features such as lumbar support, adjustable jets, or a heated surface, the other listed models provide clearer specifications for comparison.
Pros:
- Eight jets are identified in the product title
- Acrylic drop-in design in white
- Drain is included in the product title
Cons:
- Available details do not establish its dimensions or drain position
- Jet adjustability and comfort features are not specified
Verdict: Consider the K-1124 only after confirming its dimensions, drain location, and installation details; it has the basic features stated, but less information is available for comparing fit and comfort.
4. Kohler Sunward: A Wider Tub with Six Adjustable Jets
The Kohler Sunward stands out for its listed 60-by-42-inch dimensions, which make it wider than the 60-by-32-inch Devonshire and Archer. It has an end drain and six adjustable jets, with flow and direction control listed at each jet. Molded lumbar support, armrests, and a textured bottom round out its stated comfort features.
Its ExoCrylic construction is described as offering 30% lighter product weight than Kohler-brand acrylic FRP. That may make handling and mounting easier during installation, according to the product description, but you’ll still need to plan for the tub’s overall size and installation requirements. The Sunward’s wider footprint may be a benefit if it fits your room, but it can rule out layouts designed around a narrower tub.
Compared with the eight-jet choices, this model has two fewer listed jets. The tradeoff is its wider format and lighter-weight construction claim. Check the end-drain location carefully against your plumbing plan, since it differs from the reversible-drain models.
Pros:
- Listed 60-by-42-inch footprint for a wider installation
- Six adjustable jets with flow and direction control
- Molded lumbar support, armrests, and textured bottom
- ExoCrylic is described as lighter than Kohler acrylic FRP
Cons:
- Wider dimensions require more room than the 60-by-32-inch options
- Has six listed jets rather than eight
Verdict: Pick the Sunward if your bathroom can accommodate its wider footprint and you prefer its end drain and lighter-weight construction claim over having eight jets.
5. Kohler Archer with Bask: Eight Jets and a Heated Surface
This Archer pairs an eight-jet whirlpool with Kohler’s Bask heated surface. The product description says the surface warms the back and neck and offers three heat settings. It also lists adjustable jets and the Comfort Depth design, which has a stated 19-inch step-over height while retaining the depth of a standard 21-inch bath.
The heated surface is the main reason to consider this version over the standard Archer. It adds a warmth feature beyond the water massage, but also makes it important to verify the installation requirements for the specific model. The product information identifies a reversible drain, so check that option against your planned plumbing layout.
Compared with the Devonshire, this tub adds the listed heated surface and Comfort Depth design. Compared with the Sunward, it has eight rather than six listed jets, but the Sunward has a stated 60-by-42-inch size and ExoCrylic construction detail. Choose based on your bathroom dimensions and whether surface heat matters more to you than the Sunward’s wider format.
Pros:
- Bask heated surface is described as warming the back and neck
- Three heat settings are listed
- Eight adjustable jets with flow and direction control
- Comfort Depth design and reversible drain are listed
Cons:
- Additional heated-surface features make installation details especially important to verify
- The listed step-over height may still be difficult for some users
Verdict: Choose the Archer with Bask if a heated surface is a priority and its Comfort Depth design, drain arrangement, and installation needs suit your bathroom.
How to Choose a Drop-In Whirlpool Bathtub
Measure the opening and surrounding deck
Start with the space available for the tub, not the features you would like to have. The Devonshire and one Archer model are listed at 60 by 32 inches, while the Sunward is listed at 60 by 42 inches. The K-1124 and Archer with Bask descriptions here do not provide dimensions, so confirm their full specifications before comparing them with your room. Also account for the deck or surround that will frame a drop-in tub.
Match the drain to your plumbing plan
Drain design can affect how easily a tub fits your existing or planned plumbing. The Devonshire and Archer with Bask list reversible drains, while the Sunward has an end drain. The basic K-1124 description does not state the drain position. Verify the exact drain location and configuration for the model you choose rather than assuming that two tubs from the same brand use the same layout.
Compare jet count and adjustability
Four models in this guide list eight jets, while the Sunward lists six. The Devonshire, both Archer models, and Sunward also specify that their jets are adjustable; the descriptions say flow and direction can be controlled at each jet. The K-1124 listing identifies eight jets but does not explain whether they can be adjusted. More jets alone do not establish that a tub will feel better to you, so consider the controls and the placement details available for the exact model.
Think about entry height and support
The two Archer models list Comfort Depth, with a 19-inch step-over height and the depth of a standard 21-inch bath. That design may be worth comparing if entry height matters, but it is not a walk-in feature. The Devonshire, standard Archer, and Sunward list lumbar support; the Devonshire and Sunward also list armrests. Consider who will use the tub and whether these features fit their needs.
Decide whether a heated surface is worth prioritizing
The Archer with Bask is the only model here that lists a heated surface. Its description says the surface warms the back and neck and has three settings. If that feature matters to you, confirm the requirements for the exact model as part of installation planning. If you mainly want adjustable water jets and a simpler feature set, compare it with the standard Archer or Devonshire instead.
Confirm materials and installation details
The K-1124 is identified as acrylic, and the Sunward uses ExoCrylic, which the listing describes as 30% lighter than Kohler-brand acrylic FRP. These details may help you compare handling and construction, but they do not replace the manufacturer’s installation instructions. Before purchasing, confirm the tub’s full specifications, included components, required support, and any electrical or plumbing requirements with the product documentation or a qualified installer.
Check current listing details before planning a purchase
Product availability and listing details can change. Confirm the exact model number, dimensions, drain arrangement, included parts, and availability on the product page before ordering or scheduling installation. This is especially important for the K-1124 and Archer with Bask, where the information provided here does not include a complete dimension set.
Frequently Asked Questions
What is the difference between a drop-in tub and a whirlpool tub?
“Drop-in” describes how the tub is installed within a surrounding deck or structure. “Whirlpool” describes the water-jet feature. A tub can be both drop-in and whirlpool, as all five products in this guide are described.
Which of these tubs has the most jets?
The Devonshire, both Archer models, and the K-1124 list eight jets. The Sunward lists six adjustable jets. Jet count is only one comparison point; dimensions, adjustability, drain position, and comfort features matter too.
Which model has a heated surface?
The Kohler Archer with Bask is the only model here that lists a heated surface. Its product description says it warms the back and neck and provides three heat settings.
Are the two Archer tubs the same?
No. Both list eight adjustable jets and Comfort Depth, but the Archer with Bask adds a heated surface and lists a reversible drain. Compare the exact model numbers and full product details before choosing between them.
Which tubs have a reversible drain?
The Devonshire and Archer with Bask list reversible drains. The Sunward has an end drain. The standard Archer description mentions a slotted overflow but does not specify a reversible drain.
Is a 19-inch step-over height suitable for everyone?
Not necessarily. A 19-inch step-over may still be challenging for some people, and it is not the same as a walk-in tub. Consider the needs of everyone who will use the bathtub and check the full product dimensions before deciding.
What should I verify before ordering?
Check the exact model number, tub dimensions, drain position, included parts, and installation requirements. Confirm that the tub fits your planned deck and plumbing. For the Archer with Bask, review the specific requirements for the heated surface as well.
Final Recommendation
For a balanced combination of eight adjustable jets, lumbar support, armrests, and a reversible drain, the Kohler Devonshire is the clearest all-around choice when its 60-by-32-inch footprint fits your space. Choose the standard Archer if the listed Comfort Depth design and slotted overflow matter most, or the Archer with Bask if you want a heated surface. The Sunward is the option to compare for a wider layout, while the K-1124 requires extra specification checks because fewer details are provided. Confirm current availability and installation requirements before making your final choice.
