BK Resources BKS-3-1824-14-18T 90" 3-Compartment Sink with 18x24x14 Deep Bowls and Dual 18" Drainboards, NSF

BK Resources BKS-3-1824-14-18T 3-Compartment Sink with 18" x 24" x 14" Deep Bowls and Dual 18" Drainboards

The BK Resources BKS-3-1824-14-18T is a deep-bowl three-compartment stainless steel commercial sink with three 18" wide x 24" front-to-back x 14" deep bowls and dual 18" drainboards on the left and right. Overall length runs 90" with a 29-13/16" front-to-back depth and a 43-3/4" overall height including the 9" rear backsplash. The 36" working deck height accommodates standard commercial faucets, pre-rinse units, and gooseneck spouts mounted in the 8"-on-center splash-mount layout positioned across the bowl run. The 24" front-to-back bowl depth is the standard step-up from 18" front-to-back bowls when the kitchen handles full-size 12" x 20" hotel pans laid flat, sheet pans on a flat soak instead of diagonal, larger stockpots, and high-volume scratch-cooking ware that smaller bowls cannot accept without rotating or partial submersion.

T-304 18-gauge stainless steel deck and bowls, galvanized 1-5/8" round legs with adjustable high-impact corrosion-resistant feet, 1-1/2" rounded front and side edges, 1/4"-pitched drainboards for proper drainage, and three basket drains (BKDR-4) included in the carton make this a true commercial-duty wash unit ready for full code-required wash, rinse, and sanitize service in scratch kitchens with deep-pan and stockpot loads. Pre-punched 8"-on-center faucet holes accept any standard 8" OC commercial faucet. NSF listed.

Best Uses for the BKS-3-1824-14-18T

• Code-required 3-compartment wash, rinse, and sanitize stations as the primary manual ware-washing line in permitted commercial kitchens handling deep pans and stockpots
• Scratch-cooking restaurants where full-size 12" x 20" hotel pans need to lay flat in the bowl during soak and wash cycles instead of standing on edge
• Bakery and pastry operations washing full-size sheet pans (18" x 26") on a flat or near-flat soak, plus large mixing bowls from 20-quart and larger floor mixers
• Stockpot and braising pan kitchens where 12" depth bowls force tipping and the 14" depth submerges 13"-tall commercial stockpots fully upright
• Catering and banquet operations washing oversize chafer pans, full-size insulated transport containers, and Cambro food storage boxes on a 3-compartment wash line
• Butcher and protein prep wash where the 18" wide x 24" front-to-back bowl accepts whole primal cuts laid flat and large brining containers fully submerged
• Brewery, distillery, and beverage production wash for kegs, fermentation vessels, large kettles, and oversize processing equipment requiring full 3-compartment cycling
• High-volume scratch kitchens replacing an existing 18-12-18T 3-compartment line that cannot keep up with deep-pan and stockpot wash throughput

Three-Compartment Wash, Rinse, Sanitize Workflow with Dual Drainboards

The BKS-3-1824-14-18T puts three 18" x 24" x 14" bowls in a left-to-right line with an 18" drainboard on the left for soiled-in staging and an 18" drainboard on the right for clean-out air drying. That layout supports the standard code-required wash, rinse, sanitize cycle for primary manual ware-washing in any permitted commercial kitchen: dirty pans, hotel pans, stockpots, and tools land on the left drainboard, get scraped and pre-rinsed there or in the wash bowl, wash in bowl one with hot water and detergent, rinse in bowl two with clean water to remove detergent residue, sanitize in bowl three with sanitizing solution at code-specified concentration for the code-required dwell time, then air dry on the right drainboard. Three separate bowls supporting wash, rinse, and sanitize is what most local health codes require for a primary manual ware-washing station - this configuration meets that requirement and the deeper 14" bowl with 24" front-to-back footprint accommodates the heavier loads that scratch kitchens, bakeries, and stockpot operations push through the wash line.

Each 18" wide by 24" front-to-back by 14" deep bowl accepts a 12" x 20" full-size hotel pan laid completely flat with clearance on all sides for water circulation around the pan, a full-size sheet pan (18" x 26") on a near-flat soak with corners angled into the bowl walls, two 1/2-size sheet pans (13" x 18") laid flat side by side, a stockpot up to 17" diameter standing upright, and large mixing bowls from 20-quart and 30-quart commercial floor mixers without rotating the load. Three bowls in line at 18" wide each plus dividers totals approximately 54" of bowl run inside the 90" overall length, with the remaining length split between the two 18" drainboards.

18" x 24" x 14" Deep Bowls - Hotel Pan Flat Lay and Stockpot Capacity

The 24" front-to-back bowl depth (vs. 18" on the BKS-3-18-12-18T variant) is what changes daily wash workflow in deep-pan kitchens. A 12" x 20" full-size hotel pan lays completely flat in the bowl with water circulating on all sides instead of standing on edge or laying diagonal across an 18" footprint. That changes soak quality - flat pans submerge under water with even contact across the bottom and sides instead of trapping food residue along the corners that ride above the water line in narrower bowls. Sheet pans (18" x 26") sit at a much shallower angle in a 24" front-to-back bowl than in an 18" front-to-back bowl, which means water reaches more of the pan surface during a wash cycle without manual flipping mid-soak.

The 14" depth (vs. 12" on the standard 18-12-18T variant) matters for full submersion of tall items: a 12" deep bowl partially submerges 13"-14" tall stockpots, full-size hotel pans on edge, and tall mixing bowls. The 14" depth fully submerges a 12" x 20" x 4" or 12" x 20" x 6" hotel pan flat under wash, rinse, or sanitize water without overflowing, fully submerges a 13" tall commercial stockpot upright, and accepts brining containers, marinade tubs, and proofing baskets that exceed standard 12" depth bowl capacity. Each bowl holds approximately 26 gallons of water when filled to the rim - water weight at 8.34 lb per gallon means a fully filled bowl carries roughly 220 lb of water on top of the load weight, which is why BK Resources specs the 1-5/8" galvanized legs with adjustable high-impact corrosion-resistant feet rated for the loaded weight of three deep bowls plus dual drainboards at full capacity.

T-304 18-Gauge Stainless Construction

The deck and three bowls are formed from T-304 18-gauge stainless steel - the same grade used in restaurant prep tables, work tables, and food-contact equipment for its corrosion resistance and food-safe surface. The 18-gauge thickness (about 1.2 mm) is the commercial standard for compartment sinks and survives daily abuse from heavy stockpots, sheet pan corners, knife edges, and wire-bristle scrub brushes without denting or warping. The galvanized 1-5/8" round legs handle the load of three deep-bowl compartments plus dual drainboards with adjustable corrosion-resistant feet that allow leveling on uneven floors and absorb impact from delivery carts, pallet jacks, and cleaning equipment. The "TS" stainless-leg variant (BKS-3-1824-14-18TS) offers stainless legs with stainless end bracing and stainless-over-plastic adjustable bullet feet for high-humidity dishrooms, brewery wash zones, butcher rooms, and chemical-splash environments where galvanized leg corrosion would shorten service life.

The 1-1/2" rounded front and side edges serve two purposes: they stiffen the deck so it does not flex under the load of three filled deep-bowl compartments, and they create a containment lip that keeps water and food debris from running off the sink onto floors or adjacent equipment during high-volume wash cycles. The 9" rear backsplash protects the wall behind the sink and provides the mounting surface for the splash-mount faucet positioned above the bowl run.

Faucet Holes and Drain Hardware

The backsplash includes one set of pre-punched 8"-on-center faucet holes (1" diameter per the spec sheet) positioned above the bowl run so a single splash-mount faucet with a swing-arm gooseneck spout can serve all three compartments. That accepts any standard commercial 8" OC splash-mount faucet, including pre-rinse units sized for high-volume operations, gooseneck spouts that swing across the three-bowl span, and add-on dish sprayers. Three 3-1/2" basket drains (BK Resources BKDR-4) ship with the unit - one for each bowl. Install each drain in its bowl drain opening with plumber's putty or the included gasket and connect each to a standard 1-1/2" drain trap below. Stainless steel basket drains (BKDR-4-304) are available as an upgrade if the install location runs hotter water, harsher chemicals, or longer service intervals between basket cleanouts. Lever drains are also available as an option for hands-free draining between wash, rinse, and sanitize cycles - particularly useful in high-volume kitchens where staff cycle the bowls dozens of times per shift.

Specifications

Installation, Plumbing, and Clearance Requirements

The BKS-3-1824-14-18T ships with bolt-together legs and crossbracing depending on freight configuration; check the carton on receipt before delivery to confirm. At 90" overall length and 29-13/16" front-to-back, the unit will not move through standard 36"-wide commercial doorways without tipping or angling and will not turn corners in narrow service corridors - measure the entire delivery path before scheduling freight, including service elevators, dock-to-kitchen corridors, and the final install opening. The 90" overall length also means the install location needs a clear 7-1/2-foot run of wall plus end clearance for the drainboard ends. Set the sink against a wall with the 9" backsplash flush to the wall surface, level the four adjustable feet on the floor (two legs across the front, two across the back), and confirm the deck reads level both left-to-right and front-to-back across the full 90" run before plumbing the supply or drain lines. The 1-5/8" round galvanized legs accept standard commercial undershelves and crossbraces if additional storage is desired below the deck.

Faucet supply lines connect to the splash-mount faucet body installed through the 8"-on-center backsplash holes - run hot and cold supply lines up the wall behind the sink with shut-off valves accessible for service. Each basket drain installs in its bowl drain opening with the included gasket; connect each 1-1/2" tailpiece to a P-trap and run the trap waste lines to a floor drain or to the building waste stack per local code. Most jurisdictions require an indirect-waste air gap between the sink drains and the floor drain when the sink is used for food contact - confirm with the local health authority before final connection. With three deep-bowl compartments at roughly 26 gallons each plus the deck and frame weight, the loaded unit places significant point loads on the four feet - confirm the floor surface at the install location supports the loaded weight (over 800 lb fully filled with water plus equipment loads) and adjust the feet on uneven slabs to keep the deck level under load.

Frequently Asked Questions

What size pans, stockpots, and equipment fit in each 18 x 24 x 14 bowl?

Each bowl accepts a 12" x 20" full-size hotel pan laid completely flat with clearance on all sides, a full-size sheet pan (18" x 26") on a near-flat soak with corners angled into the bowl walls, two 1/2-size sheet pans (13" x 18") laid flat side by side, a stockpot up to 17" diameter standing fully upright, and 20-quart and 30-quart mixing bowls from commercial floor mixers. The 14" depth fully submerges 12" x 20" hotel pans flat, 13"-tall commercial stockpots upright, brining tubs, marinade containers, and proofing baskets under wash, rinse, or sanitize water without overflowing during agitation. Each bowl holds approximately 26 gallons of water when filled to the rim.

How much does a fully filled BKS-3-1824-14-18T weigh?

The empty unit weighs 103 lb. Each 18 x 24 x 14 bowl holds approximately 26 gallons of water, and water weighs 8.34 lb per gallon, so each bowl filled to the rim carries roughly 220 lb of water. Three bowls fully filled add about 660 lb of water weight on top of the 103 lb empty unit weight, plus the load weight of pots, pans, and equipment in the bowls. Confirm the floor surface at the install location supports the loaded weight and that the four adjustable feet sit on a stable, level slab.

Does the BKS-3-1824-14-18T meet 3-compartment sink requirements for a commercial kitchen?

Yes. The BKS-3-1824-14-18T has three separate bowls supporting wash, rinse, and sanitize cycles, which is what most local health codes require for primary manual ware-washing in any permitted commercial kitchen. The dual 18" drainboards provide soiled-in landing on the left and clean-out air drying on the right, which is the standard layout most health inspectors expect on a 3-compartment wash line. Confirm with the local health authority whether the specific bowl size and drainboard configuration meet the requirements for the operation type and volume - some jurisdictions have minimum bowl size requirements based on the largest piece of equipment or pan that needs to be washed at the station.

What is the difference between BKS-3-1824-14-18T and the BKS-3-18-12-18T?

Both units share the same 90" overall length, 18" wide bowl footprint left-to-right, dual 18" drainboards, 36" working deck, 9" backsplash, and dual-drainboard layout. The difference is bowl depth and front-to-back footprint. The BKS-3-18-12-18T has 18" x 18" x 12" bowls (23-13/16" front-to-back overall, 85 lb) for general 3-compartment wash with sheet pans, mixing bowls, and standard pots. The BKS-3-1824-14-18T (this unit) has 18" x 24" x 14" bowls (29-13/16" front-to-back overall, 103 lb) for kitchens that need 12 x 20 hotel pans laid flat, deeper stockpot submersion, and full-size sheet pans on a near-flat soak. The deeper unit is 6" deeper front-to-back and 18 lb heavier with the same dual-drainboard 90" footprint.

What is the difference between BKS-3-1824-14-18T (dual 18" drainboards) and BKS-3-1824-14-24T (dual 24" drainboards)?

Both units share the same three 18" x 24" x 14" deep bowls, 29-13/16" front-to-back depth, 36" working deck, 9" backsplash, T-304 stainless deck and bowls, and BKDR-4 drains included. The difference is drainboard width and overall length. The BKS-3-1824-14-18T (this unit) has 18" drainboards on each side for a 90" overall footprint and weighs 103 lb. The BKS-3-1824-14-24T has 24" drainboards on each side for a 102" overall footprint and weighs 110 lb - 6" wider drainboards on each side and 12" longer overall for kitchens with more soiled-in and clean-out staging volume.

What faucet fits the BKS-3-1824-14-18T?

Any commercial 8"-on-center splash-mount faucet positioned above the three-bowl run. That includes deck-mount commercial faucets with 8" hub-to-hub spacing, gooseneck spouts that swing across all three bowls, pre-rinse units sized for high-volume operations, and add-on dish sprayers. The 1" diameter faucet holes accommodate standard commercial faucet hubs. The faucet is not included with the sink - purchase separately based on application. For deep-bowl 18 x 24 compartments specifically, a longer-reach gooseneck or pre-rinse spout helps reach the far corners of each bowl for rinse-down.

Are the basket drains included or a separate purchase?

Three standard chrome-plated brass basket drains (BK Resources BKDR-4, one per bowl) are included in the carton. Stainless steel basket drains (BKDR-4-304) are available as an upgrade for harsher service environments, longer service intervals, or installations where chrome plating is not acceptable. Lever drains are also available as an option for hands-free draining between wash, rinse, and sanitize cycles, particularly useful in high-volume kitchens where staff cycle the bowls dozens of times per shift.

What is the difference between the BKS-3-1824-14-18T and the BKS-3-1824-14-18TS?

The "T" model has galvanized steel legs and standard adjustable feet at 103 lb. The "TS" model upgrades to stainless steel legs, stainless steel end bracing, and stainless-over-plastic adjustable bullet feet at 112 lb - the same deck, three deep bowls, and dual drainboards but a higher-grade chassis for environments where galvanized leg corrosion would be a problem (high-humidity dishrooms, brewery and beverage production wash zones, butcher rooms, cleaning-chemical splash zones, outdoor or covered-patio installs).

Are the drainboards pitched for drainage?

Yes. Each 18" drainboard pitches 1/4" back toward the adjacent bowl so wash water and rinse runoff drain into the compartments instead of pooling on the working surface or running off the front of the sink. The 1-1/2" rounded front and side edges contain splash and runoff inside the deck perimeter.

Will the BKS-3-1824-14-18T fit through a standard 36" doorway?

Not without significant tipping or angling. The unit is 90" long by 29-13/16" front-to-back, so the 29-13/16" dimension passes through a 36" doorway when the unit is upright, but the 90" overall length will not turn most corners in service corridors, the 43-3/4" overall height plus crated freight height needs to clear ceiling soffits, sprinkler heads, and overhead piping along the delivery path, and the 90" length combined with the 29-13/16" depth means the unit needs a long, straight delivery path with no tight turns. Measure the full path from dock to install location before scheduling freight, including service elevators, kitchen door swings, ceiling clearance, and the final install opening.

Can I install undershelves or crossbraces under the sink?

Yes. The 1-5/8" round galvanized legs accept standard commercial sink undershelves, crossbraces, and slant-rack shelves like the BK-SSH (sold separately). Undershelves add storage for cleaning chemicals, scrub buckets, glass racks, and bus tubs while keeping the deck clear for active wash work. End splashes (BKS-RES) are also available as an option to contain water at the ends of the dual drainboards in installations where the sink is not flush against side walls.

Does the sink require an indirect-waste air gap?

Most local health codes require an indirect-waste air gap between each sink drain and the floor drain or building waste stack when the sink is used for food contact. The exact air gap distance varies by jurisdiction. Confirm with the local health authority and a licensed plumber before final connection - retrofitting an air gap after the sink is in place is significantly more expensive than building it into the original install.

Is the BKS-3-1824-14-18T NSF-listed?

Yes. The unit is NSF listed for commercial food-service use, which is required by most local health authorities for any sink installed in a permitted commercial kitchen, bar, or food-service operation.
