Double Bowl Kitchen Sink with Stainless Steel Undershelf

Heavy-Gauge Double Bowl Kitchen Sink with Storage Undershelf

Two equal wash bays sit on a fully welded 304 stainless frame, with a tubular undershelf below for pots, trays, and chemical caddies. Buyers fitting out restaurants, central kitchens, or hotel back-of-house pick this unit when they need wash capacity and pan storage in a single freestanding footprint — no walls to drill, no cabinetry to coordinate.

Built for Wash-and-Stash Workstations

Most back-of-house layouts lose square meters because storage and washing get separated. This double bowl kitchen sink keeps both jobs on one footprint: deep twin basins above, an open pipe rack below sized for #20 stockpots or full-size sheet pans. The open-pipe undershelf drains naturally — no standing water, no rust pockets where solid shelves usually fail.

Where Procurement Teams Spec This Unit

• Independent restaurants and bistro chains (dish-side wash + warewash storage)

• Hotel banquet kitchens and pastry sections (pre-rinse + bulk pan staging)

• Bakeries, central commissaries, butcher rooms (heavy pan rotation)

• School cafeterias, staff canteens, and labor-camp kitchens (durable utility station)

• Outdoor catering yards and BBQ restaurants (with optional 316 upgrade for coastal/saline air)

Construction & Material Specifications

We weld this sink from a single-pour 304 stainless coil, finished to a #4 satin brushed surface that hides scratches and resists fingerprinting. Coved internal corners eliminate bacteria traps. For projects shipping to Gulf coastlines or chemical-heavy environments, 316L is available as a paid upgrade; for budget-driven domestic markets, 201 keeps unit cost down without changing the silhouette.

Why a Tubular Undershelf Instead of a Solid One

Solid sheet shelves trap drip water against the bottom seam, where rust starts within 18 months in a busy kitchen. Open-pipe construction lets water fall through, dries faster after wash-down, and weighs less for re-positioning. It also passes NSF clean-out inspection more easily because every surface is reachable with a brush.

Customization Workflow for Project Buyers

Step 1 — Drawing & Shop Approval

Send your kitchen layout (PDF/DWG) or rough sketch with target dimensions. Our drafting team returns a 2D shop drawing within 3 working days, and a 3D render on request for tender submissions.

Step 2 — Configuration Lock

Confirm bowl count, bowl depth (commonly 250 / 300 / 350 mm), faucet hole pattern (1, 3, or 4-hole), splash height, and undershelf style. Pre-drill positions for soap dispensers or pre-rinse spray arms get recorded here.

Step 3 — Sample or Pilot Run

For first-time buyers we recommend one paid sample before bulk PO. Pilot orders of 5–20 units use the same tooling as production runs — what you approve is what ships.

Step 4 — Production & QC

Standard lead time is 6 weeks for fully custom configurations from PO confirmation, including in-line weld inspection, leak test on every bowl, and packaging in 5-layer export cartons with foam corner blocks.

Quality Control & Compliance

Each finished unit goes through a four-point check before crating:

1. Weld integrity — visual + dye-penetrant on bowl-to-deck seams

2. Water retention test — fill both bowls, hold 30 minutes, inspect underside

3. Surface uniformity — grain direction, scratch-free deck, even satin

4. Dimensional accuracy — ±2 mm tolerance on length and basin opening

Xinhe holds NSF/ANSI 2, cUPC, CE, WaterMark, ISO 9001, and SGS factory audits. Certificate copies and material mill test reports (MTR) ship with every export shipment on request.
