BK Resources BKS-1-18-12-18T 1-Compartment Stainless Steel Sink - 18x18x12 Bowl, 54" with Dual 18" Drainboards
BK Resources BKS-1-18-12-18T 1-Compartment Sink with Dual 18" Drainboards
The BK Resources BKS-1-18-12-18T is a one-compartment stainless steel commercial sink with dual 18" drainboards on the left and right of an 18" x 18" x 12" bowl. Overall length runs 54" with a 23-13/16" front-to-back depth and a 43-3/4" working height including the 9" rear backsplash. The deep 12"-bowl handles full sheet pans, hotel pans, sauce pots, prep boards, and stockpot soaks that a shallower 10"-deep restaurant sink will not accommodate, and the dual drainboards give cooks and dishwashers dedicated landing zones for soiled-in and clean-out staging on either side of the wash bowl.
Prefer to pick up locally? Will call pickup is available at 11 US warehouses (Los Angeles, San Francisco, Orlando, Chicago, Denver, Dallas, Boston, Newark, Atlanta, Houston, Cleveland) on the 54" 1-compartment will-call sink. This BK Resources sink ships nationwide.
T-304 18-gauge stainless steel deck and bowl, galvanized steel legs with adjustable high-impact corrosion-resistant feet, 1-1/2" rolled front and side edges, 1/4"-pitched drainboards for proper drainage, and a basket drain (BKDR-4) included in the carton make this a true commercial-duty sink ready for daily front-of-house and back-of-house service. Pre-punched 8"-on-center splash-mount faucet holes accept any standard 8" OC commercial faucet. NSF listed.
Best Uses for the BKS-1-18-12-18T
- Bar and back-bar wash sinks for glassware, mixing tins, and bar tools
- Prep stations for vegetable washing, marination, and produce staging
- Pot and utensil sinks in tight kitchens where a 3-compartment sink will not fit
- Coffee shops, smoothie bars, and juice operations needing single-bowl wash with drying space

- Bakeries, butcher shops, and meat-processing rooms where pan and tool soaking dominates
- Concession stands, food trucks, and pop-up operations with limited width but real wash demand
Single-Compartment Sink with Dual Drainboards Workflow
A single-compartment sink with drainboards on both sides creates a continuous left-to-right or right-to-left workflow that a single-board sink does not. Soiled items land on one drainboard, get scraped and pre-rinsed there, drop into the bowl for the wash, lift out onto the opposite drainboard for air-drying or transfer to a sanitizer, and clear the station for the next batch. That continuous flow keeps water and food debris contained inside the rolled-edge perimeter, protects adjacent counters and walls from splash, and prevents cross-contamination between dirty and clean items moving across the same surface.
Each 18" drainboard pitches 1/4" toward the bowl so wash water and rinse runoff drain back into the compartment instead of pooling on the working surface. Combined with the 1-1/2" rolled front and side edges that contain splash inside the deck, the BKS-1-18-12-18T behaves like a self-contained wash station with no surrounding water management required - drop it against a wall, plumb it, and the surface manages its own drainage.
18" x 18" x 12" Deep Bowl - Full Sheet Pan Capacity
The 18" wide by 18" front-to-back by 12" deep bowl is sized to accept a full-size sheet pan (18" x 26") on a diagonal soak, a 12" x 20" hotel pan flat, a stockpot up to 11"-12" diameter standing upright, and most commercial bus tubs and prep buckets. The 12" depth matters: shallower 10"-deep bar sinks force dishwashers to soak tall items in two flips, which doubles labor on a busy line. A 12" depth also gives enough water column to fully submerge a sheet pan or sauce pot under suds or sanitizer without overflowing during agitation.
T-304 18-Gauge Stainless Construction
The deck and bowl 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 pots, knife edges, and wire-bristle scrub brushes without denting or warping. The galvanized 1-5/8" round legs handle the load with adjustable corrosion-resistant feet that allow leveling on uneven floors and absorb impact from delivery carts and cleaning equipment.
The 1-1/2" rolled front and side edges serve two purposes: they stiffen the deck so it does not flex under load, and they create a containment lip that keeps water and food debris from running off the sink onto floors or adjacent equipment. The 9" rear backsplash protects the wall behind the sink and provides the mounting surface for the splash-mount faucet, keeping the faucet body, hose, and supply lines out of the working area on the deck.
Faucet Holes and Drain Hardware
The backsplash includes pre-punched 8"-on-center faucet holes that accept any standard commercial 8" OC splash-mount faucet - including pre-rinse units, gooseneck spouts, and add-on dish sprayers. A 3-1/2" basket drain (BK Resources BKDR-4) ships with the unit; install it in the bowl with plumber's putty or the included gasket and connect to a standard 1-1/2" drain trap below. A stainless steel basket drain (BKDR-4-304) is available as an upgrade if the install location runs hotter water, harsher chemicals, or longer service intervals between basket cleanouts.

Installation, Plumbing, and Clearance Requirements
The BKS-1-18-12-18T ships fully assembled or with bolt-together legs depending on freight configuration; check the carton on receipt before delivery to confirm. Set the sink against a wall with the 9" backsplash flush to the wall surface, level the four adjustable feet on the floor, and confirm the deck reads level both left-to-right and front-to-back 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. The basket drain installs in the bowl drain opening with the included gasket; connect the 1-1/2" tailpiece to a P-trap and run the trap waste line to a floor drain or to the building waste stack per local code. Most jurisdictions require an indirect-waste air gap between the sink drain and the floor drain when the sink is used for food contact - confirm with the local health authority before final connection. Allow at least 6" of clearance behind the unit between the backsplash and the wall finish for plumbing service access if drainage is run through the wall instead of down through the floor.

Frequently Asked Questions
What size pans and pots fit in the 18" x 18" x 12" bowl?
The bowl accepts a full-size sheet pan (18" x 26") on a diagonal soak, a 12" x 20" hotel pan flat, a 1/2-size sheet pan flat with room to spare, a stockpot up to 11"-12" diameter standing upright, and most commercial bus tubs and prep buckets. The 12" depth fully submerges a sheet pan under wash water without overflowing during agitation.
Does the BKS-1-18-12-18T meet 3-compartment sink requirements for a commercial kitchen?
No. Most local health codes require a separate 3-compartment sink for wash, rinse, and sanitize when manual ware-washing is the primary dish-cleaning method. The BKS-1-18-12-18T is a one-compartment sink intended for prep, bar service, auxiliary wash, pot-and-utensil duty, or as a secondary station alongside a 3-compartment line. Confirm requirements with the local health authority before relying on this unit as a primary dish sink.
What faucet fits the BKS-1-18-12-18T?
Any commercial 8"-on-center splash-mount faucet. That includes deck-mount commercial faucets with 8" hub-to-hub spacing, gooseneck spouts, pre-rinse units, and add-on dish sprayers. The faucet is not included with the sink - purchase separately based on application.
Is the basket drain included or a separate purchase?
The standard chrome-plated brass basket drain (BK Resources BKDR-4) is included in the carton. A stainless steel basket drain (BKDR-4-304) is available as an upgrade for harsher service environments, longer service intervals, or installations where chrome plating is not acceptable.
What is the difference between BKS-1-18-12-18T and BKS-1-18-12-18TS?
The "T" model has galvanized steel legs and standard adjustable feet at 47 lb. The "TS" model upgrades to stainless steel legs, stainless steel end bracing, and stainless-over-plastic adjustable bullet feet at 56 lb - the same deck, bowl, and drainboards but a higher-grade chassis for environments where galvanized leg corrosion would be a problem (high-humidity dishrooms, cleaning-chemical splash zones, outdoor or covered-patio installs).
Are the drainboards pitched for drainage?
Yes. Both 18" drainboards pitch 1/4" back toward the bowl so wash water and rinse runoff drain into the compartment instead of pooling on the working surface or running off the front of the sink. The 1-1/2" rolled front and side edges contain splash and runoff inside the deck perimeter.
Can I install an undershelf or crossbrace 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, and bus tubs while keeping the deck clear for active wash work.
Does the sink require an indirect-waste air gap?
Most local health codes require an indirect-waste air gap between the 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.
What clearance is required behind the sink?
Allow at least 6" of clearance between the rear of the backsplash and the wall finish for plumbing service access if drain and supply lines run up through the wall. If the sink is installed against a finished wall with no rear access, drainage must run down through the floor and supply lines must enter through the deck or the side wall via a service chase.
Is the BKS-1-18-12-18T 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.
Can the BKS-1-18-12-18T be used as a hand sink?
No. Hand sinks require dedicated NSF-listed hand sink units with hands-free operation (knee, foot pedal, or sensor activation) per most health codes. The BKS-1-18-12-18T is a utility/wash sink with manual faucet operation and does not satisfy hand-washing-only requirements. Pair it with a separate dedicated hand sink in any permitted commercial kitchen.
