A deep stainless steel sink with a drainboard gives you room to wash larger items and a nearby place to set them down to dry. The right choice depends on your available space, how many basins you need, the sink’s material and gauge, and whether you want a faucet included. These picks range from compact commercial-style sinks to a larger freestanding utility station. One option does not list an integrated drainboard, so we call that out clearly.

Our Picks: Best Deep Stainless Steel Sink With Drainboard reviews
1. GRIDMANN: Compact Commercial Sink With a Left Drainboard
The GRIDMANN is a straightforward commercial-style choice for someone who wants one deep bowl and a drainboard without moving up to a large two-basin unit. Its 18 × 18-inch bowl is 12 inches deep, and the attached drainboard sits on the left. Check your room layout before ordering, since the fixed drainboard position may not suit every installation.
The sink is made from 18-gauge #304 stainless steel, and the product is listed as NSF certified for professional use. It has a 10-inch backsplash with faucet mounting holes, adjustable leveling feet, and a basket strainer with a drain assembly. The plumbing trap is not included, so plan for that separately.
This model makes sense for a compact prep area, utility room, or commercial setting where a single basin is enough. Its listed bowl depth is useful for washing items that need more room than a shallow hand sink offers. Compared with the wider options here, it takes a simpler approach and has a left-side work surface rather than a right-side one.
Pros:
- 18-gauge #304 stainless steel construction
- 12-inch-deep, 18 × 18-inch bowl
- Left drainboard and 10-inch backsplash
- Includes a basket strainer and drain assembly
Cons:
- The drainboard is fixed on the left
- Plumbing trap is not included
Verdict: Choose the GRIDMANN if you want a compact, NSF-certified single-bowl sink with a left drainboard and a clearly specified deep basin.
2. KoolMore: Two Basins for Separate Washing Tasks
The KoolMore provides two 15-inch-wide bowls and a right-side drainboard, making it the most task-focused option in this group. Separate compartments can help you keep washing and rinsing tasks apart, or let two people work at the sink at once. Its listed overall dimensions are 48 inches long by 22 inches wide, so measure carefully before choosing it.
This sink uses 18-gauge 304 stainless steel and has a 10-inch backsplash with faucet mounting holes on 8-inch centers. The drainboard is sloped to direct water away, and raised edges are intended to help contain splashes. The faucet is not included. The product information also recommends securing the sink to a wall for optimal stability.
Compared with the GRIDMANN, the KoolMore takes up more length but adds a second bowl. It may suit a busy prep or wash area where multiple tasks happen at once; it is less appealing if you need one especially large, uninterrupted basin. The supplied details do not state bowl depth, so confirm that measurement if basin depth is a deciding factor.
Pros:
- Two 15-inch-wide bowls for separate tasks
- 18-gauge 304 stainless steel construction
- Right-side sloped drainboard with raised edges
- Adjustable feet and a 10-inch backsplash
Cons:
- Faucet is not included
- Its 48-inch length requires substantial space
Verdict: Pick the KoolMore if you need two compartments and have room for a longer sink, but verify bowl depth and plan to provide a faucet.
3. BJTDLLX: Large Utility Basin With a Pull-Out Faucet
The BJTDLLX is a freestanding single-bowl utility sink with a large basin listed at about 35.8 × 21.8 inches. Its product information describes a pull-out faucet for hot and cold water, plus a base area for placing items such as pots, bowls, or washbasins. The smooth surface and rounded basin design are presented as features intended to make cleaning easier.
There is an important trade-off for this roundup: the supplied product details do not list an integrated drainboard. If a drainboard is essential, this is not a direct match for the other picks. Its stated 201 stainless steel also differs from the 304 steel listed for several alternatives, and the description does not provide a steel gauge. Check the manufacturer’s specifications and care instructions for your intended setting.
This model may suit someone who values a broad, freestanding basin and a pull-out faucet more than a built-in drying area. The reinforced frame and leveling approach described in the listing are aimed at stability, but the product details do not provide the exact bowl depth. Compare its measurements with your available space and your largest cleaning items before buying.
Pros:
- Large single basin for utility and washing tasks
- Pull-out faucet described for hot and cold water
- Base area provides a place for supplies or wash items
- Freestanding design with pre-drilled faucet and drain openings
Cons:
- An integrated drainboard is not listed
- Steel gauge and exact basin depth are not specified
Verdict: Consider the BJTDLLX only if a large utility basin and pull-out faucet matter more to you than having an integrated drainboard.
4. STMHOM: Freestanding Sink With a Right Drainboard and Shelf
The STMHOM is a larger freestanding utility sink with a single basin, a right-side sloped drainboard, and an open slotted shelf below. Its overall size is listed as 40 × 24 × 36 inches. The product description says the basin is designed for oversized cookware, grill grates, and laundry, but it does not give a specific bowl-depth measurement.
The sink is made from 304 stainless steel and includes a pull-out sprayer, hot- and cold-water supply hoses, a strainer basket, and a drying rack. Its backsplash is intended to protect the wall, while adjustable foot pads help level the unit. The lower shelf adds storage, but its open design may not suit shoppers who want a cabinet or concealed storage.
This model suits a utility room, garage, garden workspace, or other area where the larger footprint and included faucet accessories are useful. Compared with the compact GRIDMANN and Krollen Industrial sinks, it takes up more floor space and offers more storage and washing-area flexibility. Confirm that the right-side drainboard and listed overall dimensions fit your layout.
Pros:
- 304 stainless steel construction
- Right-side sloped drainboard and rear backsplash
- Includes a pull-out sprayer, hoses, strainer basket, and drying rack
- Open lower shelf and adjustable foot pads
Cons:
- Its 40 × 24-inch footprint needs room
- Exact basin depth is not specified in the supplied details
Verdict: Choose the STMHOM if you want a roomy freestanding utility station with a drainboard, pull-out sprayer, and open storage shelf.
5. Krollen Industrial: Deep Single Bowl With an Included Faucet
The Krollen Industrial pairs an 18 × 18-inch bowl with a listed depth of 14 inches and an 18-inch drainboard. Its approximate overall size is 36 × 18 inches, giving it a useful work surface without the longer footprint of the KoolMore. The product description identifies the steel as 16-gauge Type 430 and describes it as durable and corrosion resistant.
An included gooseneck faucet with hot and cold handles is a practical difference from the GRIDMANN and KoolMore, which do not list a faucet as included. The angled drainboard has raised edges to direct water back toward the sink. Adjustable galvanized legs are designed to help level the unit, and the listing gives 8-inch faucet centers and a 1½-inch IPS drain connection for installation planning.
This is a strong fit if you want a single, relatively deep basin and a built-in drying area in a compact commercial-style sink. Its Type 430 steel differs from the 304 stainless steel used by some other picks, so compare material requirements for your environment rather than assuming the grades are interchangeable. The listing provides useful connection details, but you will still need to confirm that your existing plumbing and installation space match.
Pros:
- 14-inch-deep, 18 × 18-inch bowl
- 16-gauge Type 430 stainless steel
- 18-inch drainboard with angled surface and raised edges
- Gooseneck faucet with hot and cold handles is included
Cons:
- Uses Type 430 steel rather than the 304 grade listed for several other picks
- Check faucet and drain connection details against your plumbing
Verdict: The Krollen Industrial is a practical option if a 14-inch-deep bowl, compact drainboard, and included faucet are your priorities.
How to Choose a Deep Stainless Steel Sink With Drainboard
Measure the Full Sink and Your Installation Area
Check the sink’s total width and depth, not only the bowl dimensions. A drainboard adds to the overall length, and a backsplash or faucet may affect how the sink fits against a wall. Also consider the space needed to stand and work in front of a freestanding unit. The options here range from compact models to a 48-inch-long two-basin sink.
Match Basin Depth and Shape to Your Tasks
A deeper bowl can provide more room for pots, tools, or laundry, but depth alone does not tell you how much the sink can hold. Compare the bowl’s width, length, and depth with the items you clean most often. Some product listings give precise bowl dimensions; others describe a large or deep basin without stating its depth, so look for confirmation if that measurement is important.
Choose the Right Number of Bowls
A single bowl gives you one open area for larger items. Two bowls can help separate washing, rinsing, or preparation tasks, and may let two people work at once. The trade-off is that divided bowls may provide less uninterrupted space for oversized cookware. Think about your normal routine before deciding whether a second compartment is useful.
Check Drainboard Position and Drainage Design
Drainboards in this group sit on either the left or right side, so choose a layout that works with your counters, walls, and usual workflow. A sloped surface can guide water back toward the sink, while raised edges can help contain splashes. Check which features are specified and do not assume a product has an integrated drainboard if its listing does not say so.
Compare Steel Grade and Gauge
The listed materials include 304 stainless steel in 18-gauge or unspecified-gauge models, plus 16-gauge Type 430 and 201 stainless steel options. Consider both the grade and gauge when comparing construction, and consult the seller or manufacturer about care and suitability for your setting. Do not rely on the phrase “stainless steel” alone to make the comparison.
Confirm What Comes in the Box
Included parts vary. Some models list a basket strainer or drain assembly, while others include a faucet, hoses, or drying rack. A drain assembly is not necessarily the same as a complete plumbing setup: the GRIDMANN listing, for example, says the plumbing trap is not included. Check faucet mounting details, water connections, drain size, and any parts you may need to provide separately.
Consider Height, Stability, and Storage
Freestanding sinks can be useful where there is no built-in counter, but their listed height and leveling features matter. Adjustable feet can help with uneven floors, and some listings recommend securing the unit to a wall. A lower shelf can add useful storage, while an open design leaves items visible. Make sure the sink’s height and frame suit the people and tasks it will serve.
Frequently Asked Questions
What is the advantage of a deep sink with a drainboard?
A deeper bowl can give you more room to wash larger items, while the drainboard provides a nearby place to set washed items or tools. The amount of usable space depends on the bowl and drainboard dimensions.
Which of these sinks has the deepest listed bowl?
The Krollen Industrial listing specifies a 14-inch-deep bowl. GRIDMANN lists a 12-inch depth. The supplied details for the other models do not provide an exact bowl-depth measurement.
Does the BJTDLLX sink have a drainboard?
The supplied description does not list an integrated drainboard for the BJTDLLX. If you need one attached to the sink, consider one of the other models or confirm the product’s current configuration before ordering.
Which sinks include a faucet?
The Krollen Industrial listing includes a gooseneck faucet with hot and cold handles. The STMHOM lists a pull-out sprayer and supply hoses, and the BJTDLLX title and description identify a pull-out faucet. The GRIDMANN and KoolMore descriptions do not list an included faucet.
Is 304 stainless steel the only suitable choice?
Not necessarily. The products list different stainless steel grades, and suitability depends on your use and care needs. Compare the stated grade and gauge, and check the manufacturer’s guidance for the environment where you plan to install the sink.
Do these sinks include all the plumbing parts needed for installation?
Not always. Included components vary by model, and some listings specify only certain fittings or assemblies. The GRIDMANN description states that its plumbing trap is not included. Check the product details against your faucet, drain, and water-supply setup before ordering.
Final Recommendation
For a compact commercial-style sink with a defined 12-inch bowl depth and left drainboard, the GRIDMANN is a well-specified choice. The Krollen Industrial offers the deepest listed bowl, a drainboard, and an included faucet, while the KoolMore makes more sense if you need two separate basins. For a larger freestanding work area with a pull-out sprayer and storage shelf, consider the STMHOM. The BJTDLLX may suit a utility space, but its supplied details do not list a drainboard, so it is not the closest match for this specific need.
