Atosa USA MRSA-1-D Prep Sink 18 Gauge Stainless Steel 1 Compartment Sink with Drainboards WILL CALL ONLY

MRSA-1-D 1-Compartment Prep Sink with Dual 18" Drainboards (Will-Call Pickup Only)

The MRSA-1-D is a one-compartment stainless steel commercial prep sink with one 18" x 18" x 12" deep bowl flanked by dual 18" drainboards on the left and right. Overall length runs 54" with a 24" front-to-back depth and a 44-1/2" overall height. The entire sink deck and bowl is formed from a single sheet of 18-gauge stainless steel, fused and polished into a one-piece sanitary unit, with all exposed welds ground smooth and polished to a satin finish for hygienic food-contact surfaces. Galvanized legs and adjustable ABS bullet feet support the unit at standard prep-sink working height, with a large radius on all corners both vertically and horizontally for easy cleaning and code-compliant smoothness. NSF listed.

Important: Will-Call Pickup Only

This sink is available for will-call pickup only at warehouse locations in Los Angeles, San Francisco, Orlando, Chicago, Denver, Dallas, Boston, Newark, Atlanta, Houston, and Cleveland. The MRSA-1-D ships from the manufacturer in packaging that does not survive standard freight transit at full reliability - the unit can arrive damaged when shipped via standard freight carriers, so freight shipping is not offered to protect customers from damage claims, return logistics, and replacement delays. Local pickup at any of the 11 warehouse locations above is the only way to take delivery of this specific unit.

Need It Shipped Anywhere in the US? Order This Instead

If the operation is not within driving range of one of the 11 will-call warehouse locations, or if freight shipping is required, order the BK Resources BKS-1-18-12-18T instead. The BKS-1-18-12-18T is the same configuration as the MRSA-1-D - one 18" x 18" x 12" deep bowl, dual 18" drainboards, 54" overall length, 18-gauge T-304 stainless steel, galvanized legs, NSF listed - packaged by BK Resources in freight-rated cartons that ship undamaged to any address in the continental United States via standard LTL freight. Same bowl size, same drainboard configuration, same 54" footprint, ship-anywhere availability. The BKS-1-18-12-18T includes a basket drain (BKDR-4) in the carton, has a 9" backsplash, T-304 grade stainless steel deck and bowl (vs. standard 18/304 here), and adjustable high-impact corrosion-resistant feet rather than ABS bullet feet. Choose the MRSA-1-D when local will-call pickup works for the operation; choose the BKS-1-18-12-18T when the unit needs to ship to the install location.

Best Uses for the MRSA-1-D

• Single-compartment prep sinks in commercial kitchens for produce wash, hand-rinse, and general prep work alongside a primary 3-compartment dish line
• Bar prep stations and beverage rinse where a dedicated sink keeps the bartop wash separate from food-contact wash
• Bakery and pastry prep wash for mixing bowls, sheet pans on a slight diagonal soak, and proofing equipment
• Food truck commissary and central kitchens needing a compact 1-compartment prep sink with dual staging within a 54" wall run
• Cafe, sandwich shop, and quick-service kitchens where a single bowl plus dual drainboards covers all auxiliary wash workflow without occupying the footprint of a 3-compartment line
• Garde-manger and salad station prep where the cold side of the kitchen needs a dedicated wash separate from the hot line
• Catering kitchens and event venues running batch prep where dual drainboards stage soiled-in landings and clean-out drying alongside the wash bowl
• School foodservice, daycare, and institutional kitchens needing a compact prep sink with NSF certification for permitted facilities

One-Piece Sanitary Construction

The entire sink deck, bowl, and drainboards are formed from a single sheet of 18-gauge stainless steel, fused and polished into a one-piece sanitary unit. All exposed welds are ground smooth and polished to blend with adjacent surfaces, providing a continuous satin finish across the deck. The large radius on all corners - both vertically (where the bowl walls meet the deck) and horizontally (where the bowl bottom meets the bowl walls) - eliminates sharp interior corners where food residue, grease, or biofilm can accumulate, which is why NSF lists the unit for commercial food-service use. The 18-gauge thickness (about 1.2 mm) is the commercial standard for prep sinks and survives daily abuse from sheet pan corners, scrub brushes, and cleaning chemicals without denting or warping under normal commercial use.

The dual 18" drainboards on each side of the bowl are creased and angled to direct water runoff back toward the bowl during wash cycles, which keeps water and food debris from running off the front of the sink onto the kitchen floor or pooling on the working surface during high-volume prep. The bright satin finish on the entire deck simplifies daily cleaning - no recessed seams, no welded joints to scrub around, no hidden pockets for residue.

18" x 18" x 12" Bowl Capacity

The 18" wide by 18" front-to-back by 12" deep bowl accepts standard commercial prep loads: full-size 12" x 20" hotel pans (laid on edge or diagonal, since 18" front-to-back does not allow flat lay), 1/2-size sheet pans (13" x 18") on a slight angle, mixing bowls from 12-quart and 20-quart counter mixers, 5-gallon buckets, standard prep tubs, and most produce-wash and protein-rinse loads. The 12" depth submerges most prep equipment under wash water without overflowing during agitation. For applications that need full-flat hotel pan submersion or 14" depth for tall stockpots, the 18-12 bowl is undersized - those operations need the 24" front-to-back, 14"-depth bowl variants instead.

Galvanized Legs and Adjustable ABS Bullet Feet

The unit ships with four galvanized steel legs at 22-1/2" leg height, supporting the 18-gauge stainless deck and bowl at standard prep-sink working height. Adjustable ABS bullet feet at the base of each leg allow leveling on uneven floors, a quarter-inch to a half-inch of vertical adjustment per foot, which matters because 1-compartment sinks installed in older kitchens often sit on slabs that have settled or pitched toward floor drains. The bullet feet also absorb impact from delivery carts, pallet jacks, mop buckets, and cleaning equipment that occasionally hits the leg base during daily operations. ABS plastic at the foot resists corrosion from cleaning chemicals and standing water that splashes off mop buckets and cleaning operations, where bare steel feet would corrode and stain over time.

Specifications

Will-Call Pickup Locations

Pickup is available at the following 11 warehouse locations: Los Angeles, San Francisco, Orlando, Chicago, Denver, Dallas, Boston, Newark, Atlanta, Houston, and Cleveland. After ordering online, customers receive will-call pickup instructions with the warehouse address, hours, and pickup procedure for the selected location. Bring the order confirmation and a photo ID for pickup. Forklift loading or hand-cart assistance is typically available at each warehouse during posted hours - confirm with the local warehouse before arrival if a specific loading method is needed. Buyers outside reasonable driving range of these 11 locations should order the BK Resources BKS-1-18-12-18T instead, which ships nationwide via standard LTL freight with no will-call restriction.

Installation, Plumbing, and Clearance Requirements

The MRSA-1-D ships fully assembled - no field assembly of legs or drainboards required. At 54" overall length and 24" front-to-back, the unit fits through standard 36"-wide commercial doorways with the 24" dimension leading and clears most service corridors and elevators. The 44-1/2" overall height clears ceiling soffits, sprinkler heads, and overhead piping in nearly every commercial kitchen. Set the sink against a wall, level the four adjustable ABS bullet feet on the floor, and confirm the deck reads level both left-to-right and front-to-back across the full 54" run before plumbing the supply or drain lines. The galvanized legs accept standard commercial undershelves and crossbraces if additional storage is desired below the deck.

Faucets are sold separately. The bowl drain is a single drain opening centered in the bowl bottom; connect to a standard 1-1/2" 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. The 12" bowl depth at full water capacity holds approximately 17 gallons - water weight at 8.34 lb per gallon means a fully filled bowl carries roughly 140 lb of water plus the load weight of pans and equipment, which the four-leg galvanized chassis supports without issue under normal commercial use.

Frequently Asked Questions

Why is the MRSA-1-D will-call pickup only?

The unit ships from the manufacturer in packaging that does not consistently survive standard LTL freight transit at full reliability - the sink can arrive damaged when shipped via standard freight carriers due to the way the manufacturer packs the unit for outbound. Rather than ship a unit that has a meaningful chance of arriving damaged (and creating return logistics, replacement delays, and damage claims for customers), the sink is offered for will-call pickup only at the 11 warehouse locations where the unit can be hand-loaded directly into the customer's vehicle without going through freight handling. Customers who need the unit shipped should order the BK Resources BKS-1-18-12-18T instead - same configuration, packed for freight, ships nationwide without damage.

Where can I pick up the MRSA-1-D?

Pickup is available at warehouse locations in Los Angeles, San Francisco, Orlando, Chicago, Denver, Dallas, Boston, Newark, Atlanta, Houston, and Cleveland. After ordering online, the order confirmation includes will-call pickup instructions with the warehouse address, hours of operation, and pickup procedure for the selected location. Bring the order confirmation and a photo ID for pickup.

Can the MRSA-1-D be shipped via standard LTL freight if I am willing to accept the damage risk?

No. Freight shipping is not offered for this unit because the damage rate is high enough that shipping it would create unacceptable customer experience and return logistics. Customers who want this configuration shipped should order the BK Resources BKS-1-18-12-18T instead - same 18 x 18 x 12 bowl, dual 18 inch drainboards, 54 inch footprint, packed by the manufacturer for freight transit, ships undamaged to any address in the continental US.

What is the difference between the MRSA-1-D and the BK Resources BKS-1-18-12-18T?

Both units share the same overall configuration: one 18 x 18 x 12 bowl, dual 18 inch drainboards, 54 inch overall length, 18-gauge stainless steel, galvanized legs, NSF listed. The MRSA-1-D is one-piece construction (single sheet fused and polished) at 24 inch front-to-back, 44-1/2 inch overall height, with ABS bullet feet, no drain included, faucets sold separately, 45 lb net weight, will-call pickup only. The BKS-1-18-12-18T is welded T-304 stainless construction at 23-13/16 inch front-to-back, 43-3/4 inch overall height with a 9 inch backsplash, adjustable high-impact corrosion-resistant feet, BKDR-4 basket drain included, faucets sold separately, 47 lb net weight, ships nationwide via LTL freight. Functionally interchangeable for prep-sink applications - choose based on whether will-call pickup or freight shipping fits the operation.

What size pans, mixing bowls, and equipment fit in the 18 x 18 x 12 bowl?

The bowl accepts 1/2-size sheet pans (13 x 18 inch) on a slight angle, mixing bowls from 12-quart and 20-quart counter mixers, 5-gallon buckets, standard prep tubs, full-size 12 x 20 hotel pans on edge or diagonal (the 18 inch front-to-back does not allow flat lay of full-size hotel pans), and most produce-wash and protein-rinse loads. The 12 inch depth submerges most prep equipment under wash water without overflowing during agitation. For applications needing full-flat 12 x 20 hotel pan submersion or 14 inch depth for tall stockpots, this bowl is undersized.

Are the drainboards usable as work surfaces?

Yes. Each 18 inch drainboard provides a stainless work surface alongside the bowl for staging soiled-in items on the left and clean-out items on the right, or for use as auxiliary prep space when the bowl is not actively running a wash cycle. The drainboards are creased and angled to direct water back toward the bowl, so any water that lands on the drainboard runs into the sink rather than pooling on the deck or running off the front edge.

Is a faucet included?

No. Faucets are sold separately. The unit accepts standard commercial 8-inch on-center splash-mount faucets with the faucet hub centered on the rear backsplash above the bowl. Pre-rinse units, gooseneck spouts, and add-on dish sprayers all fit standard 8-inch on-center hub spacing.

Is a basket drain included?

No. The bowl ships with a single drain opening but no basket drain or drain hardware in the carton - basket drains are sold separately. For installs that need the drain hardware included in the carton (chrome-plated brass basket drain, gasket, lockring), the BK Resources BKS-1-18-12-18T ships with a BKDR-4 basket drain in the carton standard.

Is the MRSA-1-D 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. The one-piece construction with large-radius corners, ground-smooth welds, and satin finish meets the NSF criteria for cleanability and food-contact surface integrity.

What warranty applies to the MRSA-1-D?

The manufacturer covers the unit under a 90-day workmanship warranty against defects in materials and assembly from the date of purchase. Damage from shipping (which is why the unit is will-call only), improper installation, abuse, neglect, or normal wear is not covered. Keep the order confirmation and pickup documentation for warranty claim records.

Will the MRSA-1-D fit through a standard 36-inch doorway?

Yes. The unit is 54 inches long by 24 inches front-to-back, so the 24-inch dimension passes through a 36-inch doorway when the unit is upright. The 54-inch length will navigate most service corridors but may need angling around tight 90-degree turns. The 44-1/2 inch overall height clears most ceiling soffits, sprinkler heads, and overhead piping along the path from the warehouse loading dock to the install location. Confirm clearances at the install site before pickup, particularly if the kitchen is in a basement or has narrow service corridors.

Can the unit be modified or upgraded after purchase?

The one-piece construction means the bowl, drainboards, and deck cannot be reconfigured after manufacture - the unit ships in the factory configuration. The galvanized legs accept standard commercial sink undershelves, crossbraces, and slant-rack shelves (sold separately) for additional below-deck storage. End splashes are not factory-installed but can be added if the install location requires water containment at the drainboard ends.

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.
