The best 2 compartment sink with a drainboard depends on available space, bowl size, and whether you need one or two landing areas. The 72-inch KoolMore model is best for kitchens needing drainboards on both sides, while the Kratos suits buyers seeking 18-by-18-inch bowls and a backsplash. Compact KoolMore options provide smaller bowls for tighter work areas.

| KoolMore 57-inch | Right-side landing space | One 18-inch right drainboard |
| Kratos 29N-006 | 18-inch bowls with backsplash | Two 18-inch drainboards |
| KoolMore SB121610-16R3 | Compact work areas | One 16-inch left drainboard |
| KoolMore SB151512-15R3 | Mid-size bowls | One 15-inch right drainboard |
KoolMore 72-Inch Sink With Two Drainboards
Best for: Commercial kitchens that need landing space on both sides of the bowls. This model has two 18-by-18-by-14-inch compartments and two 18-inch drainboards, supporting separate areas for drying, stacking, or food preparation.
Its listed material is 304-type, 18-gauge stainless steel. The drainboards have slanted surfaces to help excess water drain away. The two bowls can support simultaneous work, such as washing and rinsing.
Limitation: At 72 inches long, it requires more installation space than the other selected sinks. Measure the intended location and access path before choosing it.
KoolMore 57-Inch Sink With Right Drainboard
Best for: Buyers who want two large bowls and a dedicated right-side landing area. The bowls measure 18 by 18 by 14 inches, and the product listing specifies an 18-inch right drainboard for drying dishes or holding items during preparation.
The sink is made from 16-gauge stainless steel. Its two bowls are suited to tasks such as rinsing, washing, thawing, and prep work, with room for two staff members to work at the sink.
Limitation: The listed configuration provides a right-side drainboard, not one on each side. Confirm that the drainboard orientation fits the room’s workflow.
Kratos 29N-006 With Backsplash
Best for: Commercial buyers looking for two 18-inch drainboards, two 18-by-18-by-12-inch bowls, and a backsplash. The backsplash helps limit water splashing onto nearby walls or floors, while the listed pre-punched faucet centers are spaced 8 inches apart.
This option is selected for its clearly specified bowl dimensions and two-sided drainboard layout. The bowls provide room for washing and drying tools, according to the product details.
Limitation: The listed warranty is void if the sink is used in a residential setting. The listing specifies a 90-day limited warranty for food trucks or mobile applications.
KoolMore SB121610 With Left Drainboard
Best for: Work areas that need a shorter sink with two compartments and one landing zone. Its listed overall dimensions are 43 inches long by 22 inches wide by 44.5 inches high. The bowls are listed as 12 by 16 by 10 inches, with a 16-inch left drainboard.
The sink uses 304-type, 18-gauge stainless steel. Its slanted drainboard is designed to shed excess water and can be used for drying dishes or holding food during preparation.
Limitation: The smaller bowls may be less suitable for large pots or bulky items than the 18-inch-bowl models. Check the bowl dimensions against the items you wash most often.
KoolMore SB151512 With Right Drainboard
Best for: Buyers who want a middle-ground bowl size and a right-side drying area. The listing gives two 15-by-15-by-12-inch bowls and a 15-inch right drainboard, with overall dimensions of 48 by 22 by 44.5 inches.
Its 304-type, 18-gauge stainless steel construction is described as rust- and corrosion-resistant. The two bowls can help separate tasks, while the sloped drainboard provides space for drying dishes or staging food.
Limitation: It has one drainboard, on the right. Choose a different configuration if you need landing space on both sides or specifically need a left-side board.
Buying Guide: How to Choose a Two-Compartment Sink
What bowl size do you need?
Compare the interior bowl dimensions with the largest pans, utensils, or equipment you expect to wash. The selected options range from 12-by-16-inch bowls to 18-by-18-inch bowls. Deeper bowls may also matter when soaking items, so compare bowl height as well as width and length.
Do you need one drainboard or two?
A single drainboard can be sufficient when the sink sits against a wall or when workflow favors one landing area. Choose dual drainboards when you need separate staging or drying space on both sides. Check whether a single board is left- or right-sided before ordering.
Will the sink fit the room?
Measure the available floor and wall space, including room for plumbing and normal staff movement. Compare the product’s overall dimensions—not just its bowls—with the installation area. A long sink can provide more staging space but may limit circulation in a narrow kitchen.
Which material and features should you compare?
Review the stated stainless-steel type and gauge, backsplash, faucet-center spacing, and drainboard slope. Product descriptions vary, so verify each detail for the specific model. For commercial use, also confirm that the sink’s intended setting and any listed warranty terms fit your operation.
Frequently Asked Questions
What is a two-compartment sink used for?
It provides two separate bowls for tasks such as washing and rinsing, or for separating different stages of prep and cleanup.
Is a drainboard necessary?
A drainboard provides nearby space for drying dishes or staging items. The right configuration depends on your workflow and available room.
Should I choose a left- or right-side drainboard?
Choose the side that best matches your work sequence and surrounding counters, equipment, and traffic. Confirm the orientation in the product details.
Are all selected sinks the same size?
No. Their bowl sizes and overall lengths differ. Compare both measurements with your cookware and installation area before buying.
Can a commercial sink be used at home?
Use depends on the specific product terms and installation requirements. The Kratos listing says its warranty is void for residential use, so review the applicable product details before choosing it.
