Restaurant 1-Compartment Sink with Left 18" Drainboard - 39" Stainless Steel - Will Call Pickup at 11 US Warehouses
1-Compartment Commercial Sink with Left-Side 18-Inch Drainboard (39" Overall, 18x18x12 Bowl)
This 1-compartment commercial sink gives small kitchens, prep stations, and bar back-of-house a single 18 by 18 by 12 inch bowl with an 18 inch drainboard on the left side. Overall footprint is 39 inches wide by 24 inches deep, and 44-1/2 inches tall to the top of the rear backsplash. The entire bowl, deck, drainboard, and backsplash are formed from one sheet of 18-gauge stainless steel, fused and polished into a single sanitary unit. Galvanized legs and adjustable ABS bullet feet keep the sink stable on uneven kitchen floors.
The left-hand drainboard is creased and angled to direct water back into the bowl, which keeps the deck cleaner and reduces standing water around the prep area. Large radius corners both vertically and horizontally make the bowl easy to wipe down, and all exposed welds are ground smooth and polished to blend into the satin finish. The sink ships NSF listed for commercial foodservice use and carries a 90-day workmanship warranty. Faucets are sold separately. This unit may be damaged during standard freight shipping, so pickup is the recommended fulfillment method.

Best Use Cases for a 1-Compartment Sink with Left Drainboard
- Bar back-of-house glass and bottle rinsing where staff approach from the right and stage rinsed items to the left
- Compact prep stations washing produce, herbs, and small batch ingredients
- Coffee shop and cafe rinse stations for milk pitchers, blender jars, and steam wand cloths
- Pizzeria and sandwich shop hand-prep washing under 39 inches of wall space
- Food truck commissary rinse and pre-rinse stations where space and orientation are tight
- Catering and concession trailers needing a single bowl with a left landing zone
- School, church, and small-volume kitchen produce-rinse and pot-fill duty
- Retail bakery decorating and tool-rinse stations next to a worktable on the right
Why Left Drainboard Orientation Matters
The "L" in MRSA-1-L means the 18 inch drainboard sits on the left side of the bowl when you face the sink. Drainboard orientation should match how staff move through the prep zone. If the dish or product flow runs right to left, with dirty items entering from the right and rinsed items staging to the left, this left-drainboard layout shortens reach and keeps water headed back into the bowl rather than across the deck. If your flow runs the opposite direction, the right-drainboard variant is the better fit.
The drainboard itself is creased and angled, which means the deck slopes back toward the bowl so rinse water and any debris drain into the compartment rather than pooling on the work surface or running off the front edge.
Bowl Capacity and What Fits in 18 by 18 by 12
The 18 by 18 by 12 inch bowl holds approximately 14 gallons of water at the rim, or about 117 pounds of water at full capacity. In practical terms the bowl will accept a full-size 18 by 26 inch sheet pan on a slight diagonal, two half-size 13 by 18 sheet pans flat, a 12 by 20 hotel pan with room to spare, stockpots up to roughly 16 inches in diameter, and standard bus tubs and gray dish boxes. The 12 inch depth gives enough clearance to fully submerge most prep cookware without water sloshing over the rear backsplash.
One-Piece 18-Gauge Stainless Construction
The bowl, deck, drainboard, and 9 inch rear backsplash are drawn from a single sheet of 18-gauge stainless steel. There are no welded seams along the bowl-to-deck transition, so there is no joint for grease, soap residue, or food particles to collect in. All exposed welds at the legs and corners are ground smooth and polished to match the satin finish on the deck. Vertical and horizontal corners are formed with a large radius, which makes the bowl interior easier to wipe down and meets the radius-corner requirements common in NSF and local health code reviews.
Legs, Feet, and Working Height
Legs are galvanized steel at 22-1/2 inches, which puts the deck working height at approximately 34-3/4 inches off the floor. Feet are adjustable ABS bullet feet that thread up and down for floor leveling. The 22-1/2 inch leg standard is shared across the Mix Rite single-bowl line, so this sink will sit at the same deck height as adjacent compartment sinks, drainboards, and worktables of the same series.
Faucet Holes and Drain Hardware
The rear backsplash is pre-punched for a deck-mount faucet on 8 inch centers behind the bowl. Faucets are sold separately, which is standard for commercial compartment sinks because operators usually have a preferred spout length, swing radius, and pre-rinse style for the application. Drain hardware is also not included with this unit, so plan to purchase a basket strainer, a lever-handle waste valve, or a rotary-handle drain to match local plumbing code and your kitchen's grease management setup. Most operators specify a 1-1/2 inch lever drain for prep applications and a 2 inch drain for higher-volume rinse duty.

Installation and Plumbing Notes
This is a freestanding floor-mounted compartment sink, not a wall-hung unit. Position the sink with at least 6 inches of clearance behind the backsplash and adjacent to a floor sink or floor drain so the waste line can air-gap to the floor sink rather than drain directly into the building waste line. An air gap is required by most local plumbing codes for any sink used to wash food contact surfaces or food product.
Plumbing Rough-In Checklist
- Hot and cold supply lines stubbed within reach of the 8 inch faucet centers behind the bowl
- Floor sink or hub drain located within the discharge throw of the 1-1/2 or 2 inch waste tailpiece
- Air gap maintained between the waste tailpiece and the floor sink rim
- Backflow prevention on the supply side per local plumbing code
- Shutoff valves at each supply line for service access
Floor and Clearance Requirements
- Floor must be level enough that bullet-foot adjustment can compensate for variation
- Allow side clearance for elbow room and a wash bucket or trash on the bowl side
- Allow front clearance for a worker to stand and lean into the bowl without hitting another fixture
- Plan rear clearance for plumbing service and to keep the backsplash off finished wall surfaces
Will Call Pickup Locations
This sink is sold as will call pickup only. Standard freight carriers tend to bend or dent the drainboard or backsplash on a single-bowl unit of this size, so we limit fulfillment to local pickup at 11 US warehouse locations. Buyers within reasonable driving distance of any of these warehouses can pick up directly. Buyers outside that radius should order the BK Resources nationwide-shipped equivalent linked above.

Need It Shipped Anywhere in the US? Order This Instead
The BK Resources BKS-1-18-12-18L 1-compartment sink with left drainboard is the closest direct equivalent built for nationwide LTL freight delivery. It uses the same 18 by 18 by 12 inch bowl size with an 18 inch left drainboard and lands at a similar overall footprint. The BK version steps up to T-304 stainless steel, includes BKDR-4 drain hardware, and is engineered with rounded corners and reinforced backsplash for freight handling. If you need this sink shipped to a job site, a buildout, or a city outside our 11 pickup locations, that is the one to order.
Frequently Asked Questions
What does the L in MRSA-1-L stand for?
The L indicates the drainboard is on the left side of the bowl as you face the sink. The matching right-drainboard model is MRSA-1-R, and the dual-drainboard model is MRSA-1-D.
How is this different from MRSA-1-D?
MRSA-1-D has two 18 inch drainboards, one on each side of the bowl, for a total overall length of 54 inches. MRSA-1-L has one 18 inch drainboard on the left only, for a 39 inch overall length. Choose the L variant when wall space is tight or when only one staging zone is needed.
Why is this sink will call only?
Single-bowl stainless sinks with a drainboard are prone to bending and denting along the drainboard and backsplash during standard LTL freight handling. Rather than ship a unit that may arrive damaged, we limit this product to local pickup at 11 US warehouses. The BK Resources equivalent is engineered for freight and is the right choice for shipped orders.
Can I drive to a pickup location from out of state?
Yes. Buyers regularly drive to the closest warehouse, especially for sink and worktable orders where freight risk is high. Confirm pickup hours and bring a vehicle large enough to accept a 39 inch by 24 inch crated unit.
Are faucets and drains included?
No. Faucets are sold separately, which is standard for commercial compartment sinks. Drain hardware is also not included, so plan to purchase basket strainers and lever or rotary waste valves to match the application.
What is the working deck height?
Approximately 34-3/4 inches off the floor with the 22-1/2 inch galvanized legs and standard bullet-foot extension. Adjust the bullet feet to fine tune for floor variation.
Is this sink NSF certified?
Yes. The unit is NSF listed for commercial foodservice use and meets the radius-corner and one-piece sanitary construction requirements common in health code reviews.
What size faucet should I order?
The backsplash is pre-punched on 8 inch centers, so order a deck-mount commercial faucet with 8 inch centers and a spout long enough to reach the center of the bowl. A 12 inch swing spout is a common starting point for an 18 inch wide bowl.
What gauge is the stainless steel?
18 gauge across the entire one-piece body, including the bowl, deck, drainboard, and rear backsplash. 18 gauge is the standard specification for commercial prep and rinse sinks.
How much does the sink weigh?
Net weight is 39 pounds. Two people can comfortably move and set the sink during install.
What is the warranty?
90 days on workmanship. Faucets, drains, and other separately purchased components carry their own manufacturer warranties.
Does the drainboard have a raised edge?
The drainboard has a creased and angled surface that directs water back toward the bowl. The perimeter has a rolled edge with a large radius transition where it meets the bowl deck and the rear backsplash.
Can I use this sink as a hand sink?
An 18 by 18 by 12 inch bowl is larger than a dedicated hand sink and the sink is designed for prep, rinse, and pot duty rather than handwashing. Most health codes require a separate, dedicated handwash sink in food prep zones, so use this unit for its intended prep and rinse role.
