Stainless Steel Sink with Drainboard · Model DD8050
Single Bowl Drop-In Stainless Steel Sink with Drainboard
A stainless steel sink with drainboard made for kitchens that wash and dry in the same place. The body is drawn in one piece, so the 415 × 350 mm bowl and the ribbed drainboard share a single surface with no welded seam between them. The overall footprint is 800 × 500 mm, the bowl is 145 mm deep, and three pre-drilled holes on the rear ledge take a faucet, a soap dispenser or a water-purifier tap. Supplied as a top-mount drop-in unit for OEM and ODM orders from 500 pcs.

Why Buyers Specify This Single Bowl Sink with Drainboard
Six design decisions behind the DD8050, each written as Feature → Advantage → Benefit so you can match them against your own project requirements.
One-Piece Deep Drawn Body
Feature — Bowl and drainboard are formed in a single stamping from one stainless steel blank.
Advantage — There is no weld line where the bowl meets the drainboard, and no overlap joint along the rim.
Benefit — Nothing catches food residue at a seam, and there is no joint that can open up and leak after years of use.
Ribbed Drainboard, Self-Returning Runoff
Feature — Press-formed ribs run across the full length of the drainboard.
Advantage — Water from drying plates and glasses follows the grooves back into the bowl instead of spreading across the surface.
Benefit — Tableware dries where it stands and the countertop around the sink stays dry.
Rear Back-Splash Lip
Feature — A raised lip is formed along the rear rim of the sink deck.
Advantage — It blocks water from running backwards toward the cabinet opening.
Benefit — The cabinet board and the wall behind the sink stay protected from standing water.
3-Hole Faucet Ledge
Feature — Three pre-drilled holes on the rear deck, plus a prepared soap-dispenser position.
Advantage — A faucet, soap dispenser or water-purifier tap can be fitted in any combination, and American-style faucets drop straight in.
Benefit — One sink covers washing, dispensing and filtered water without extra drilling on site.
Wide Flat Rim for Drop-In Fitting
Feature — A wide, flat rim with a 28 mm raised edge, pre-punched with three faucet holes, sized to sit over a 767 × 470 mm countertop cutout.
Advantage — The rim simply rests on the countertop over the cutout, with no mounting clips or brackets, and the flat landing covers small cutout irregularities.
Benefit — Faster and cleaner installation on site, and the sink can be lifted out later for service or replacement without damaging the counter.
Sloped Bowl Bottom and Sound Pad
Feature — The bowl base is sloped toward the drain, with a sound-deadening pad fitted to the back of the bowl.
Advantage — Water runs off completely rather than pooling in the corners, and the bowl rings quieter under a running tap.
Benefit — Less wiping-down after use and a noticeably calmer kitchen or utility room.

Where This Stainless Utility Sink with Drainboard Fits
The single bowl plus drainboard layout suits any wash-and-dry station where countertop space is limited and tableware needs somewhere to stand.
Bright island kitchens — the drainboard takes over the drying job so the countertop stays clear.Compact and patterned-tile kitchens — a 800 mm footprint fits where a double bowl sink will not.Everyday prep corners — rinse, drain and stack in one continuous movement.
How This Drop-In Drainboard Sink Is Built
Construction details that affect how the sink performs after installation — from the drawn bowl geometry to the surface treatment applied to the finished body.
One drawn body: bowl, drainboard, rim and rear back-splash lip formed from a single blank.
Smooth Rounded Corners
The bowl is drawn with generous radii and no sharp internal edges, so food residue lifts off with a cloth and there is nothing to catch a hand during washing.
Rim and Back-Splash
A formed rim stiffens the whole sink body and keeps the unit flat against the countertop after installation, while the raised rear lip stops water running back toward the cabinet.
Bottom Slope and Drain Position
The bowl base slopes toward a centred drain, so water leaves completely and the bowl does not need to be wiped out after every use.
Satin Finish (Standard)
The default surface for the DD8050. A fine brushed grain hides fingerprints and water marks far better than a polished surface, which suits busy kitchens and utility areas.
Mirror Polish / Electropolished (On Request)
Both finishes can be specified for the same body. Mirror polish gives a bright reflective face for display-led kitchens; electropolishing leaves a smoother, more corrosion-resistant skin for harsher environments.

Frequently Asked Questions
What is a top-mount sink, and is the DD8050 a drop-in model?
A top-mount sink — also called a drop-in or inset sink — sits on top of the countertop with its rim resting on the surface, rather than being fixed underneath the worktop the way an undermount sink is. The DD8050 is a top-mount design with a wide flat rim, so it is dropped into a 767 × 470 mm cutout from above. That means no under-counter brackets, no exposed cut edge to seal from below, and the sink can be lifted out again if it ever needs replacing.
Can the bowl and drainboard be reversed — bowl on the right, drainer on the left?
Yes. Both orientations are offered: bowl-left with the drainboard on the right, and drainboard-left with the bowl on the right. Tell us which hand you need when ordering; the tooling already covers both, so it does not change the price or the lead time.
What drain opening size does this sink with drainboard take?
The bowl is pressed with a φ114 mm counterbore and a φ89 mm (3.5 in) through-opening, which matches the standard 3.5 in basket strainer used in the United States. A waste kit is an optional accessory rather than a standard inclusion, so confirm the exact drain specification with us when you place the order and we will set the tooling to match.
What are the MOQ, lead time and trade terms?
The minimum order quantity is 500 pcs. Lead time is 30–40 days after receipt of deposit, and we ship on EXW factory, FOB Shenzhen or Guangzhou, or DDP destination terms. OEM and ODM orders are accepted, including custom logos and custom specifications. Mixed loading of cartons and pallets on one container is available on request.
Does the sink come with a sound pad and anti-condensation coating?
A sound-deadening pad is fitted to the back of the bowl as standard, and an additional pad can be applied to the drainboard if you want the whole unit deadened. An anti-condensation undercoating on the back of the bowl is available as an option — it is worth specifying where the sink sits over a cabinet in a humid climate. Both are confirmed at the ordering stage so they are included in the production schedule.
