BK Resources BKS-2-18-12-18T Stainless Steel 2-Compartment Sink with Dual 18" Drainboards, 18×18×12 Bowls, NSF
BK Resources BKS-2-18-12-18T 2-Compartment Sink with Dual 18" Drainboards
The BK Resources BKS-2-18-12-18T is a two-compartment stainless steel commercial sink with dual 18" drainboards on the left and right of two 18" x 18" x 12" deep bowls. Overall length runs 72" with a 23-13/16" 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 between the two bowls. Two bowls flanked by drainboards is the standard underbar wash footprint, the standard auxiliary prep wash for kitchens running a separate 3-compartment dish line, and the code-approved layout for operations that local health authorities permit to run a 2-bowl wash-and-sanitize cycle in place of a full 3-compartment line.

Two-Bowl Wash Workflow with Dual Drainboards
The BKS-2-18-12-18T puts two 18" x 18" x 12" 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 underbar wash workflow used in commercial bars and the code-approved 2-compartment cycle some local health authorities permit: dirty glassware, tools, or pots 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 and sanitize in bowl two with sanitizing solution at code-specified concentration for the code-required dwell time, then air dry on the right drainboard. Most jurisdictions still require a full 3-compartment sink for primary manual ware-washing in any permitted commercial kitchen - confirm with the local health authority whether a 2-compartment sink is acceptable as the primary wash station or only as auxiliary equipment.
Each 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 fully submerges a sheet pan or hotel pan under wash, rinse, or sanitize water without overflowing during agitation. Two bowls in line at 18" each plus dividers totals approximately 36" of bowl run inside the 72" overall length, with the remaining length split between the two 18" drainboards.
18" x 18" x 12" Deep Bowls - Bar and Prep Capacity
The 12" bowl depth matters: shallower 10"-deep bar sinks force operators to soak tall items in two flips, which slows underbar service and doubles labor on a busy line. A 12" depth gives enough water column to fully submerge a cocktail shaker, mixing tin set, blender pitcher, or large bar tool under wash or sanitize without overflowing during agitation. The 18" front-to-back bowl width gives enough working room for two-handed scrubbing of pans and bar equipment without banging knuckles against the bowl walls, and the 18" left-to-right width accepts most commercial wash bus tubs lowered straight into the bowl for tool-and-utensil presoak.
T-304 18-Gauge Stainless Construction
The deck and two 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 pots, knife edges, and wire-bristle scrub brushes without denting or warping. The galvanized 1-5/8" round legs handle the load of two full bowls plus dual drainboards with adjustable corrosion-resistant feet that allow leveling on uneven floors and absorb impact from delivery carts and cleaning equipment. The "TS" stainless-leg variant (BKS-2-18-12-18TS) offers stainless legs with stainless end bracing and stainless-over-plastic adjustable bullet feet for high-humidity dishrooms, underbar splash zones, 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 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 centered between the two bowls.
Faucet Holes and Drain Hardware
The backsplash includes one set of pre-punched 8"-on-center faucet holes positioned between the two bowls so a single splash-mount faucet with a swing-arm gooseneck spout can serve both compartments. That accepts any standard commercial 8" OC splash-mount faucet, including pre-rinse units, gooseneck spouts that swing to either bowl, and add-on dish sprayers. Two 3-1/2" basket drains (BK Resources BKDR-4) ship with the unit - one for each bowl. Install each drain in the 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 and sanitize cycles - particularly useful in underbar installs where bartenders cycle the bowls dozens of times per shift.

Installation, Plumbing, and Clearance Requirements
The BKS-2-18-12-18T ships with bolt-together legs and crossbracing depending on freight configuration; check the carton on receipt before delivery to confirm. At 72" overall length, the unit will not move through standard 36"-wide commercial doorways without tipping or angling - measure the delivery path before scheduling freight, including service elevators, dock-to-kitchen corridors, and the final install opening. 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 72" 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 between the two bowls - 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. For underbar installs, confirm that the sink front projects no further into the customer-side bar than the bartender working aisle allows, and that the rear of the sink leaves room for refrigeration, glass storage, or speed rails behind the working position.

Frequently Asked Questions
What size pans, glassware, and tools fit in each 18 x 18 x 12 bowl?
Each 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, blender pitchers, mixing tin sets, large bar tools, and most commercial bus tubs and prep buckets. The 12" depth fully submerges tall items under wash or sanitize water without overflowing during agitation.
Does the BKS-2-18-12-18T meet 3-compartment sink requirements for a commercial kitchen?
No. Most local health codes require a full 3-compartment sink for primary manual ware-washing in any permitted commercial kitchen, with three separate bowls supporting wash, rinse, and sanitize cycles. The BKS-2-18-12-18T is a two-compartment sink intended for underbar wash, auxiliary prep wash, produce wash, or as a secondary station alongside a 3-compartment dish line. Some jurisdictions allow a 2-compartment wash-and-sanitize cycle for limited-service operations (bars, coffee bars, beverage stations) - confirm with the local health authority before installing this unit as a primary wash station.
What is the difference between BKS-2-18-12-18T and the other 2-compartment dual-drainboard models?
BK Resources offers 2-compartment dual-drainboard sinks in several bowl sizes. The BKS-2-1620-12-18T has 16" x 20" x 12" bowls (68" overall, 66 lb). The BKS-2-18-12-18T has 18" x 18" x 12" bowls (72" overall, 67 lb). The BKS-2-20-12-18T has 20" x 20" x 12" bowls (76" overall, 71 lb). The BKS-2-24-14-24T steps up to 24" x 24" x 14" bowls with 24" drainboards (96" overall, 96 lb) for stockpot and large-vessel applications. Choose the 18-12-18T for the standard 18×18×12 bowl footprint that matches single-compartment 18×18 sinks and the 18×18 3-compartment line for matched bowl size across stations.
What faucet fits the BKS-2-18-12-18T?
Any commercial 8"-on-center splash-mount faucet positioned between the two bowls. That includes deck-mount commercial faucets with 8" hub-to-hub spacing, gooseneck spouts that swing to either bowl, pre-rinse units, and add-on dish sprayers. The faucet is not included with the sink - purchase separately based on application.
Are the basket drains included or a separate purchase?
Two 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 and sanitize cycles, particularly useful in underbar installs where bartenders cycle the bowls dozens of times per shift.
What is the difference between the BKS-2-18-12-18T and the BKS-2-18-12-18TS?
The "T" model has galvanized steel legs and standard adjustable feet at 67 lb. The "TS" model upgrades to stainless steel legs, stainless steel end bracing, and stainless-over-plastic adjustable bullet feet at 76 lb - the same deck, two bowls, and dual drainboards but a higher-grade chassis for environments where galvanized leg corrosion would be a problem (high-humidity dishrooms, underbar splash zones, 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-2-18-12-18T fit through a standard 36" doorway?
Not without angling or tipping. The unit is 72" long by 23-13/16" front-to-back, so the 23-13/16" dimension passes through a 36" doorway easily - but the 72" overall length will not turn corners in tight service corridors, and the 43-3/4" overall height plus crated freight height needs to clear ceiling soffits, sprinkler heads, and overhead piping along the delivery path. Measure the full path from dock to install location before scheduling freight, including service elevators, kitchen door swings, and the final install opening.
Can the BKS-2-18-12-18T be used as an underbar wash sink?
Yes. The 72" overall length, 23-13/16" front-to-back depth, and 36" working deck height fit standard underbar runs in most commercial bar build-outs. Two bowls flanked by 18" drainboards is the classic underbar wash layout - one bowl for wash, one for sanitize, with drainboards for soiled-in glassware and clean-out air drying. Confirm front-of-bar projection and rear clearance for refrigeration, speed rails, and glass storage before final placement. For underbar installs in high-splash environments, the stainless-leg "TS" variant resists corrosion better than galvanized over time.
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-2-18-12-18T 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.
