BK Resources BKS-2-18-12 41" 2-Compartment Sink with 18×18×12 Bowls, NSF
BK Resources BKS-2-18-12 2-Compartment Sink (No Drainboards)
The BK Resources BKS-2-18-12 is a two-compartment stainless steel commercial sink with two 18" x 18" x 12" deep bowls and no drainboards. Overall length runs 41" 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 in line with no attached drainboards is the smallest 2-compartment footprint in the BK Resources lineup at this bowl size, which makes it the choice for tight underbar wash bays, food trucks, concession trailers, galley kitchens, corner installs, and any operation that needs a code-friendly two-bowl wash without giving up wall length to integrated drainboards.
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, and two basket drains (BKDR-4) included in the carton make this a true commercial-duty sink ready for daily front-of-bar 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-2-18-12
- Underbar and back-bar 2-compartment wash sinks for glassware, mixing tins, ice scoops, and bar tools where wall length is at a premium
- Food trucks, concession trailers, and pop-up operations with strict footprint limits but real two-bowl wash demand
- Auxiliary prep and produce wash stations alongside a main 3-compartment dish line
- Coffee bars, smoothie operations, and juice bars using the dual-bowl wash for blenders, processing tools, and pitchers
- Compact bar build-outs where a 72" dual-drainboard 2-compartment sink will not fit
- Pot and utensil soak stations supplementing a main wash line during peak service
- Mop and utility wash where two compartments separate cleaning chemicals from rinse water
- Vegetable wash and dedicated produce prep where local code permits a 2-bowl wash-and-sanitize cycle
No-Drainboard Layout - Smallest 2-Bowl 18×18 Footprint
The BKS-2-18-12 puts two 18" x 18" x 12" bowls flush to both ends of a 41" deck with no drainboards attached. That is the shortest 2-compartment configuration BK Resources offers at this bowl size - a full 31" shorter than the equivalent dual-drainboard variant (BKS-2-18-12-18T at 72" overall) and 35" shorter than the dual-drainboard footprint with both 18" drainboards in place. Operators who need staging for soiled-in or clean-out items typically pair this sink with an adjacent prep table, bus tub on a rack, drying rack, glass rack, or transfer cart - the tradeoff is footprint versus integrated drying surface. End splashes (BKS-RES) are available as an option to contain water at the ends of the bowl line in installations where the sink is not flush against side walls.
That tradeoff matters because in a tight build-out, the difference between a 41" sink and a 72" sink is the difference between fitting the unit at all and re-engineering the bar plan. Compact bar build-outs, food trucks, concession trailers, and small commissary operations frequently need the two-bowl wash but cannot spare 31 additional inches of length for attached drainboards. The 1-1/2" rounded front and side edges still contain splash inside the deck perimeter, and the 9" rear backsplash protects the wall behind the unit, so the no-drainboard layout still behaves like a self-contained wash station - just without the integrated drying real estate.
18" x 18" x 12" Deep Bowls - Bar and Prep Capacity
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, blender pitchers, mixing tin sets, large bar tools, and most commercial bus tubs and prep buckets. The 12" 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, or large bar tool under wash or sanitize without overflowing during agitation. The bowls in the no-drainboard BKS-2-18-12 are identical to the bowls in the dual-drainboard 18-12-18T variant - same depth, same capacity, same plumbing requirements - only the surrounding deck differs.
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 with adjustable corrosion-resistant feet that allow leveling on uneven floors and absorb impact from delivery carts and cleaning equipment. The "S" stainless-leg variant (BKS-2-18-12S) 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 ships fully assembled or with bolt-together legs depending on freight configuration; check the carton on receipt before delivery to confirm. At 41" overall length and 23-13/16" front-to-back, the unit will pass through standard 36"-wide commercial doorways on its end - confirm the delivery path 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, 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 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 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 is a two-compartment sink intended for underbar wash, auxiliary prep wash, produce wash, mop and utility 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, BKS-2-1620-12, and BKS-2-24-14?
All three are 2-compartment no-drainboard sinks. The BKS-2-1620-12 has 16" x 20" x 12" bowls (37" overall, 25-13/16" front-to-back, 51 lb). The BKS-2-18-12 has 18" x 18" x 12" bowls (41" overall, 23-13/16" front-to-back, 51 lb) - the same bowl size as the popular 18×18×12 single- and 3-compartment lines for matched bowl size across stations. The BKS-2-24-14 steps up to 24" x 24" x 14" bowls (53" overall, 29-13/16" front-to-back, 74 lb) for stockpot, full hotel pan, and large-vessel applications. Choose the BKS-2-18-12 when the 18×18 bowl footprint matches your other sinks and underbar bowl wash demand fits within an 11"-12" diameter pot capacity.
What is the difference between BKS-2-18-12 (no drainboards) and BKS-2-18-12-18T (dual drainboards)?
Both share the same two 18" x 18" x 12" bowls and 23-13/16" front-to-back depth. The no-drainboard BKS-2-18-12 is 41" overall length. The dual-drainboard BKS-2-18-12-18T adds 18" drainboards on both sides of the bowl line, taking the unit to 72" overall length. Choose the no-drainboard variant when wall length is the binding constraint and an adjacent prep table, bus tub, glass rack, or transfer cart handles soiled-in and clean-out staging. Choose the dual-drainboard variant when integrated drying space matters more than minimizing footprint.
What faucet fits the BKS-2-18-12?
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 and the BKS-2-18-12S?
The standard model has galvanized steel legs and standard adjustable feet at 51 lb. The S model upgrades to stainless steel legs, stainless steel end bracing, and stainless-over-plastic adjustable bullet feet at 60 lb - the same deck and two bowls 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, food trucks subject to road salt, outdoor or covered-patio installs).
How do I stage soiled or clean items without drainboards?
Operators typically place a stainless prep table, bus tub on a rack, glass drying rack, transfer cart, or wire drying rack adjacent to the sink to handle soiled-in and clean-out staging. End splashes (BKS-RES) are available as an option to contain water at the ends of the bowl line where the sink is not flush against side walls. The no-drainboard layout trades integrated drying space for the smallest possible 2-compartment 18×18 footprint - operators who already have prep table, bus tub, or glass rack staging near the sink lose nothing by choosing this variant.
Can the BKS-2-18-12 be used as an underbar wash sink in a tight bar build-out?
Yes. The 41" overall length, 23-13/16" front-to-back depth, and 36" working deck height fit underbar runs in compact bar build-outs where a 72" dual-drainboard 2-compartment sink will not. Two bowls in line is the classic underbar wash layout - one bowl for wash, one for sanitize - and pairing the no-drainboard variant with an adjacent glass rack or speed-rail station gives the same workflow without the wall-length cost. For underbar installs in high-splash environments, the stainless-leg "S" variant resists corrosion better than galvanized over time.
Will the BKS-2-18-12 fit in a food truck or concession trailer?
The 41" overall length and 23-13/16" front-to-back depth fit most food truck and concession trailer wash bays where a wider drainboard sink will not. Confirm interior clearances against the 43-3/4" overall height (with backsplash) and the 36" working deck height before committing the layout. Food trucks typically wall-mount the unit through the backsplash riser turn-up section to prevent shifting during transit - fasteners are not included.
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.
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 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.
