3-Compartment Sink 120"W with Dual 24" Drainboards, 24x24x14 Bowls, 18-Gauge Stainless
Three-Compartment Commercial Sink with Dual 24-Inch Drainboards (120-Inch Overall, Three 24x24x14 Bowls, Stainless Legs)
This three-compartment commercial sink pairs three full-size 24 by 24 by 14 inch bowls with two 24 inch drainboards in a 120 inch overall footprint, giving back-of-house teams a true wash, rinse, and sanitize line plus generous integrated landing zones on both ends. Overall dimensions are 120 inches wide by 29-1/2 inches deep, and 43-3/4 inches tall to the top of the rear backsplash. Each bowl runs 24 inches square, which accepts a full-size 18 by 26 inch sheet pan flat with room around the perimeter and stockpots up to roughly 22 inches in diameter. The bowls, deck, drainboards, and rear backsplash are formed from a single sheet of 18-gauge type 304 stainless steel, fused and polished into a one-piece sanitary unit.
The drainboards are creased and angled toward the bowls so rinse water and pre-wash residue drain directly into the wash bay rather than pooling on the deck. Large radius corners both vertically and horizontally make each bowl easy to wipe down, and all exposed welds are ground smooth and polished to blend into the satin finish on the deck. Each bowl ships with a 3.5 inch drain basket included. Stainless steel legs and sockets with 1 inch adjustable bullet feet keep the sink stable on uneven kitchen floors. The unit is NSF listed for commercial foodservice use and carries a 90-day workmanship warranty. Faucets are sold separately.

Best Use Cases for a Three-Compartment Sink with 24-Inch Bowls
- Three-bay warewashing lines that need maximum bowl capacity for full-size sheet pans, hotel pans, and tall stockpots
- BBQ, smokehouse, and barbeque catering kitchens washing oversized racks, drip pans, and rotisserie hardware in three bays
- Pizzeria and stockpot operations that need 14 inch bowl depth and 24 inch square footprint for tall pots and full-size hotel pans flat
- High-volume catering kitchens and commissaries running pan, rack, and utensil wash cycles back to back
- Bakeries and donut shops washing full-size 18 by 26 inch sheet pans, proofing tubs, and oversized mixer bowls
- Health code zones that require a dedicated three-compartment sink separate from prep and handwash sinks
- Buildouts that have at least 120 inches of wall length available and want generous 24 inch drainboards on both ends
- Schools, healthcare kitchens, and institutional foodservice running standardized three-bay protocols at full scale
Why Choose 24x24x14 Bowls With 24-Inch Drainboards
The 24 by 24 by 14 inch bowl is the largest standard compartment bowl size and the right choice when staff routinely wash full-size sheet pans, full-size hotel pans, or 20-quart-plus stockpots in a single bowl. The 14 inch depth lets a tall stockpot sit fully submerged with several inches of water clearance above the rim, and the 24 inch square footprint accepts an 18 by 26 inch sheet pan flat without diagonal angling.
The 24 inch drainboards on each end give a full sheet pan worth of staging space for incoming soiled items on the left and outgoing clean items on the right. That extra 6 inches of drainboard length per side over an 18-inch-drainboard variant matters when staff are staging multiple sheet pans or full-size hotel pans at once during a rush. The trade-off is overall length climbs to 120 inches, so the buildout needs at least 10 feet of clear wall to fit this sink.
Bowl Capacity and What Fits in 24 by 24 by 14
Each 24 by 24 by 14 inch bowl holds approximately 35 gallons of water at the rim, or about 290 pounds of water at full capacity. With three bowls in line, total water capacity is roughly 105 gallons split into three independent bays for wash, rinse, and sanitize. In practical terms each bowl will accept a full-size 18 by 26 inch sheet pan flat with room around the perimeter, a 12 by 20 hotel pan flat with room for a second pan, stockpots up to roughly 22 inches in diameter, full-size 18 by 26 cooling racks, and oversized cookware that simply will not fit in an 18 inch bowl. The 14 inch depth gives enough clearance to fully submerge most sheet pans, hotel pans, and tall stockpots without water sloshing over the rear backsplash.
One-Piece 18-Gauge 304 Stainless Construction
The three bowls, the deck between them, both 24 inch drainboards, and the rear backsplash are drawn from a single sheet of 18-gauge type 304 stainless steel. Type 304 is the standard food-grade stainless alloy and offers better corrosion resistance than 430-series stainless used on entry-level sinks. There are no welded seams along the bowl-to-deck or deck-to-drainboard transitions, so there is no joint for grease, soap residue, or food particles to collect in. All exposed welds at the legs and corners are ground smooth and polished to match the satin finish on the deck. Vertical and horizontal corners are formed with a 3/4 inch radius, which makes each bowl interior easier to wipe down and meets the radius-corner requirements common in NSF and local health code reviews.
Drainboard Design and Slope
Both drainboards measure 24 inches and are creased and angled toward the bowls so water drains back into the wash bay rather than pooling on the deck. The crease pattern keeps rinse water on a controlled path even when staff stage rinsed pans and racks across the full drainboard surface. The drainboards are part of the same one-piece body as the bowls, which means there is no welded seam along the bowl-to-drainboard transition for grease and soap to collect in.
The left drainboard is generally used as the soiled landing zone for items entering the wash sequence, and the right drainboard is used as the clean landing zone for items exiting the sanitize bay. This left-soiled-to-right-clean flow is the standard three-bay protocol in most health code training programs.
Stainless Legs, Sockets, and Working Height
Legs are stainless steel at 22-1/2 inches with stainless steel sockets, an upgrade from the galvanized legs used on entry-level commercial sinks. Stainless legs handle wet floor and detergent splash environments better over the long run and resist the rust streaks that galvanized legs can develop in busy prep zones. Feet are 1 inch adjustable bullet feet that thread up and down for floor leveling.
The 22-1/2 inch leg standard puts the deck working height at approximately 33-3/4 inches off the floor with the 14 inch bowl, which is the comfortable working height for a deep-bowl wash setup. Plan adjacent worktable, dish landing table, and drainboard table heights to match.
Faucet Holes, Drain Baskets, and Plumbing Hardware
The rear backsplash is pre-punched for deck-mount faucets on 8 inch centers behind the bowls. Faucets are sold separately, which is standard for commercial compartment sinks because operators usually have a preferred spout length, swing radius, and pre-rinse style for the application. Most three-bay setups run one deck-mount commercial faucet behind the wash bay and a second behind the rinse bay, leaving the sanitize bay to fill from the rinse bay or from a separate sanitizer dispensing line. A 12 to 14 inch swing spout long enough to swing across two adjacent bowls is a common starting point for a 24 inch wide bowl.
Each bowl ships with a 3.5 inch drain basket included, which is the standard drain size for a 24 by 24 bowl. This is a notable inclusion at this price point and saves operators the cost of buying drains separately. Lever-handle waste valves or rotary-handle drains can be added if the local plumbing code or the operator's preference requires them, but the included basket strainers will satisfy most standard installs.

Installation and Plumbing Notes
This is a freestanding floor-mounted three-compartment sink, not a wall-hung unit. Position the sink with at least 6 inches of clearance behind the backsplash and adjacent to a floor sink or floor drain so the waste lines can air-gap to the floor sink rather than drain directly into the building waste line. An air gap is required by most local plumbing codes for any sink used to wash food contact surfaces or food product.
Plumbing Rough-In Checklist
- Hot and cold supply lines stubbed within reach of the 8 inch faucet centers behind the bowls
- Two faucet rough-ins planned, one each behind the wash and rinse bays
- Floor sink or hub drain located within the discharge throw of the 1-1/2 or 2 inch waste tailpieces
- Air gap maintained between each waste tailpiece and the floor sink rim
- Backflow prevention on the supply side per local plumbing code
- Shutoff valves at each supply line for service access
Floor and Clearance Requirements
- Floor must be level enough that bullet-foot adjustment can compensate for variation
- Allow side clearance for a worker to swing a sheet pan from the soiled drainboard into the wash bay
- Allow front clearance for a worker to stand and lean into each of the three bowls without hitting another fixture
- Plan rear clearance for plumbing service and to keep the backsplash off finished wall surfaces
- 10 feet of clear wall length minimum to accept the full 120 inch sink without crowding adjacent fixtures
Three-Bay Wash, Rinse, Sanitize Setup
- Left drainboard staged as the soiled landing zone for incoming pans, racks, and utensils
- Wash bay filled with hot water and detergent to manufacturer-specified concentration
- Rinse bay filled with clean hot water and refilled as it gets soapy
- Sanitize bay filled with sanitizer solution at the concentration specified on the sanitizer label
- Right drainboard staged as the clean landing zone for items exiting the sanitize bay to air dry
- Test strips on hand to verify sanitizer concentration during shift
Will Call Pickup Locations
This sink is sold as will call pickup only. Standard freight carriers tend to bend or dent the backsplash, drainboards, and bowl rims on a 120 inch three-bay unit, so we limit fulfillment to local pickup at 11 US warehouse locations. Buyers within reasonable driving distance of any of these warehouses can pick up directly. Buyers outside that radius should order the BK Resources nationwide-shipped equivalent linked above.

Frequently Asked Questions
What does the F31D24 in SS2424F31D24 mean?
F31 indicates a three-compartment configuration with full-depth bowls. D24 indicates dual 24 inch drainboards, one on each end of the sink. The leading SS2424 indicates a 24 inch wide by 24 inch front-to-back bowl size.
How is this different from the SS2424F31N no-drainboard model?
SS2424F31N is 77 inches overall with three 24 by 24 by 14 inch bowls and no drainboards. SS2424F31D24 keeps the same three 24-inch bowls and adds two 24 inch drainboards, bringing overall length to 120 inches. Choose SS2424F31D24 when integrated landing zones on both ends matter and 10 feet of wall length is available.
How is this different from the 18x24x14 SS1824F31D18?
SS1824F31D18 has three 18 by 24 by 14 inch bowls with dual 18 inch drainboards in a 90 inch overall length. SS2424F31D24 steps up to three 24 by 24 by 14 inch bowls with dual 24 inch drainboards in a 120 inch overall length. Choose this 2424 model when stockpots over 18 inches in diameter or larger sheet-pan staging is part of the workflow and wall space allows.
Why are the faucets sold separately?
Operators usually have a preferred spout length, swing radius, and pre-rinse style for the application. Most three-bay setups use two faucets, one each behind the wash and rinse bays. Selling faucets separately lets the operator match the sink to the workflow rather than ship a generic faucet that may not fit the install.
Are the drains included?
Yes. Each bowl ships with a 3.5 inch drain basket included. This is a notable inclusion at this price point. Faucets remain sold separately.
Why is this sink will call only?
A 120 inch three-bay sink with two drainboards is prone to bending and denting along the backsplash, drainboards, and bowl rims during standard LTL freight handling. Rather than ship a unit that may arrive damaged, we limit this product to local pickup at 11 US warehouses. The BK Resources equivalent is engineered for freight.
Can I drive to a pickup location from out of state?
Yes. Buyers regularly drive to the closest warehouse, especially for sink and worktable orders where freight risk is high. Confirm pickup hours and bring a vehicle long enough to accept a 120 inch by 29-1/2 inch crated unit.
What is the working deck height?
Approximately 33-3/4 inches off the floor with the 22-1/2 inch stainless legs and standard 1 inch bullet-foot extension. Adjust the bullet feet to fine tune for floor variation.
Is this sink NSF certified?
Yes. The unit is NSF listed for commercial foodservice use and meets radius-corner and one-piece sanitary construction requirements common in health code reviews.
What size faucet should I order?
The backsplash is pre-punched on 8 inch centers. Order deck-mount commercial faucets with 8 inch centers and a spout long enough to swing across two adjacent bowls. A 12 to 14 inch swing spout is a common starting point.
What gauge is the stainless steel?
18 gauge type 304 across the entire one-piece body, including all three bowls, the deck, both drainboards, and the rear backsplash.
Why does this sink have stainless legs instead of galvanized?
Stainless legs and sockets handle wet floor and detergent splash environments better than galvanized legs over the long run. They resist rust streaks that galvanized legs can develop in busy prep zones and match the food-grade alloy of the bowls. This is an upgrade over entry-level commercial sinks.
How much does the sink weigh?
Net weight is 122.57 pounds and gross crated weight is 145.72 pounds. Two-person handling is recommended for plumbing connection and final positioning on a sink this size.
What is the warranty?
90 days on workmanship. Faucets and other separately purchased components carry their own manufacturer warranties.
Can I use this sink as a prep sink?
A three-compartment commercial sink is designed for ware washing. Most health codes require a separate dedicated prep sink for food preparation and a separate dedicated handwash sink for hand washing.
