BK Resources BKS-1-18-12 One-Compartment Stainless Steel Sink, 18" x 18" x 12" Bowl, No Drainboards, NSF
BK Resources BKS-1-18-12 1-Compartment Sink (No Drainboards)
The BK Resources BKS-1-18-12 is a one-compartment stainless steel commercial sink with no drainboards - the smallest footprint in the BKS-1-18-12 family at 23-1/2" overall length, 23-13/16" front-to-back depth, and 43-3/4" working height including the 9" rear backsplash. The deep 18" x 18" x 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 no-drainboard layout keeps the entire unit under 24" wide so it slots into galley alcoves, undercounter gaps between reach-in equipment, corner installs, food trucks, concession stands, and any kitchen where a 38-1/2" single-drainboard or 54" dual-drainboard sink simply will not fit.

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, 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
- Bar and back-bar wash sinks for glassware, mixing tins, and bar tools where width is at a premium
- Food trucks, concession trailers, and pop-up operations with strict footprint limits
- Galley-style and corner kitchens where any drainboard footprint will not clear adjacent walls or appliances
- Undercounter alcoves between reach-in refrigerators, prep tables, and ware-washing equipment
- Coffee shops, smoothie bars, and juice operations needing a single-bowl wash in a tight bar build-out
- Auxiliary wash stations supplementing a main 3-compartment dish line where staging happens on a separate prep table
- Bakeries and butcher shops where pan and tool soaking dominates and dedicated drying rack space already exists nearby
- Mop, prep, or utility installs in service corridors and back-of-house storage rooms
No-Drainboard Layout - Smallest Footprint in the Family
The BKS-1-18-12 is the no-drainboard variant of the BKS-1-18-12 family. The bowl runs flush to both ends of the deck with no drying space attached - overall length is 23-1/2", which is roughly the same as the bowl plus the rolled-edge perimeter and nothing else. That makes it the only variant in the family that fits a 24"-wide alcove or undercounter opening. Operators who need staging space for soiled-in or clean-out items typically pair this sink with an adjacent prep table, bus tub, drying rack, or transfer cart instead of a built-on drainboard - the tradeoff is footprint versus integrated drying surface.
That tradeoff matters because in a tight build-out, the difference between a 23-1/2" sink and a 38-1/2" single-drainboard sink is the difference between fitting the unit at all and re-engineering the kitchen plan. Food trucks, concession trailers, mobile commissary trailers, and small bar build-outs frequently need the wash bowl but cannot spare 15 additional inches of width for an attached drainboard. The 1-1/2" rolled 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 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. The bowl in the no-drainboard BKS-1-18-12 is identical to the bowl in the 18L, 18R, and 18T variants - same depth, same capacity, same plumbing requirements - only the surrounding deck differs.
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. If desired, holes can be drilled through the riser turn-up section to fasten the sink to the wall - fasteners are not included.
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 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. Optional wall-mount holes can be drilled through the backsplash riser turn-up section to fasten the sink to the wall (fasteners not included) - useful in food trucks and other mobile installs where vibration could shift the unit.
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.
What is the difference between BKS-1-18-12, BKS-1-18-12-18L, BKS-1-18-12-18R, and BKS-1-18-12-18T?
All four variants share the same 18" x 18" x 12" bowl and 23-13/16" front-to-back depth. The BKS-1-18-12 has no drainboards (23-1/2" overall length, smallest footprint). The 18L adds a single 18" left drainboard (38-1/2" overall, left-to-right workflow). The 18R adds a single 18" right drainboard (38-1/2" overall, right-to-left workflow). The 18T adds drainboards on both sides (54" overall, dual-side workflow with the most drying space). Choose the no-drainboard BKS-1-18-12 when footprint is the binding constraint and an adjacent prep table, bus tub, or drying rack handles staging.
How do I stage soiled or clean items without a drainboard?
Operators typically place a stainless prep table, bus tub on a rack, or wire drying rack adjacent to the sink to handle soiled-in and clean-out staging. In a food truck or compact bar, a wall-mount drying rack above the sink or a sliding cutting board across the bowl can substitute for an integrated drainboard. The no-drainboard footprint trades integrated drying space for the smallest possible width - operators who already have prep table or bus tub staging near the sink lose nothing by choosing this variant.
Does the BKS-1-18-12 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 is a one-compartment sink intended for prep, bar service, auxiliary wash, pot-and-utensil duty, mop and utility service, 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?
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 the BKS-1-18-12 and the BKS-1-18-12-S?
The standard model has galvanized steel legs and standard adjustable feet at 32 lb. The "S" model upgrades to stainless steel legs, stainless steel end bracing, and stainless-over-plastic adjustable bullet feet at 41 lb - the same deck and bowl but a higher-grade chassis for environments where galvanized leg corrosion would be a problem (high-humidity dishrooms, cleaning-chemical splash zones, food trucks subject to road salt, outdoor or covered-patio installs).
Can the sink be wall-mounted or attached to a wall?
Yes, optionally. Holes can be drilled through the backsplash riser turn-up section to fasten the sink to the wall. Fasteners are not included with the unit. Wall fastening is recommended for food truck installs, mobile concession trailers, high-vibration locations (next to ware-washing equipment, near loading dock walls), and any install where the sink might shift during heavy active use.
Will the BKS-1-18-12 fit in a food truck or concession trailer?
Yes - the 23-1/2" 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 34-3/4" working deck height before committing the layout. Many mobile operators wall-mount the unit through the backsplash riser turn-up section to prevent shifting during transit.
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.
Is the BKS-1-18-12 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.
