Quartz Integrated Sink (Kitchen)
Integrated Quartz Sink for Seamless Countertop Projects
This quartz integrated sink is engineered as a fully integrated kitchen sink solution, designed to be fabricated as part of the entire countertop rather than installed as a separate unit. By combining the sink and countertop into one continuous quartz surface, it delivers a clean, unified look while eliminating visible seams around the sink edge.
For B2B kitchen projects, this integrated sink structure simplifies coordination between sink manufacturing and countertop fabrication, improving installation accuracy and long-term structural integrity.
Quartz Composite Construction for Long-Term Durability
Manufactured using high-density quartz composite, this integrated sink offers superior resistance to stains, scratches, heat, and daily washing impact. Compared with traditional granite sinks or stainless steel sinks, quartz composite sinks provide a non-porous surface that is easier to clean and engineered to last a lifetime in high-usage kitchen environments.
The material composition is optimized for consistent color, structural strength, and controlled tolerances required in standardized OEM production.
Single Bowl Integrated Kitchen Sink with Ample Space
The single bowl kitchen sink configuration provides ample space for washing large pans, cookware, and daily kitchen tasks. Integrated into the countertop surface, the deep bowl design improves functionality without compromising kitchen style or space efficiency.
This quartz integrated kitchen sink is suitable for modern kitchens, residential developments, serviced apartments, and premium renovation projects where both aesthetics and practicality are required.
Designed for Undermount Installation & OEM Programs
This integrated sink is compatible with undermount installation methods commonly used in quartz and granite countertop systems. Bowl dimensions, edge geometry, and drainage positioning are engineered to align with fabrication workflows used by countertop suppliers and project installers.
Available for OEM & ODM programs, the sink supports custom sizes, multiple color options beyond white, and accessory integration to match different kitchen styles and project specifications.
Deep Single Bowl
A 635 mm body carrying 305 mm of bowl depth
Published size for SN6448 is 25 × 19 × 12 inches. That is 635 mm across the counter and 305 mm from rim to base, so depth is doing more work here than width.
Narrow footprint, deep bowl
The plan dimension is 635 × 482 mm against a published depth of 305 mm. Short counter runs are where that combination gets specified.
Undermount, no divider
Install tag and specification both record undermount. The bowl is listed as single, so nothing has to line up against the cabinet centre line.
The listing calls it an integrated kitchen sink. That names the catalogue format, not how the body is produced. Work from the drawing, and find it in the undermount kitchen sink listing.
Fit & Clearance
Trap space is the constraint under a 305 mm bowl
Two published numbers set the site work on SN6448.
The body is 635 mm wide on plan. Check the base unit against that figure, plus whatever the fabricator's fixing method takes up at each side.
Below the counter, 305 mm of bowl leaves less room for services. Waste, trap and any disposal unit share what is left, so have the plumber sign the run off first.
Cutout size and corner radius are not published. Ask for the drawing before the countertop is templated.
Construction & Finish
Matte Grey is the only surface fact on record
Matte Grey is the colour on the model sheet. It is also the only surface information that sheet carries.
The finish stated for SN6448
Quartz composite in Matte Grey is what the record holds. A physical sample is the reference for approval, not a screen image.
Wall thickness, weight and surface test data do not appear on this page. Where a programme needs those figures, put them in the RFQ.
Hold one signed grey sample on each side.
Compliance
No certification mark is listed against SN6448
Drawing, material declaration and packing specification are what most submittals need. Ask for them as one set.
There is no certification or listing mark in the SN6448 record. Size, mount and colour are what it holds, and none of that is market approval.
Documentation is scoped per market. Put the destination country in the enquiry so the reply covers the right paperwork.
Procurement
Ordering SN6448 at wholesale volume
A deep bowl in a narrow body is a cube problem before anything else.
The 305 mm depth affects how the model stacks and how many pieces fill a container. Raise carton and pallet arrangement in the first enquiry.
Colour and size changes on this model are quoted as development work. Start that conversation at the SANIKB OEM and ODM program.
Include these details with the RFQ
- Pieces of SN6448 per shipment
- Destination country for the shipment
- Approval method for the Matte Grey finish
- Cabinet opening width the body must clear
- Drain position, and whether a waste kit is included
- Carton and pallet build for the 305 mm depth
- Container utilisation target
- Packaging text and artwork
Fifty pieces is published against this model number. Ask how it applies if the booking mixes models.
How we work
From enquiry to shipment
A factory-direct process built for importers, distributors and project buyers. No trading layer in between.
-
01
Send the enquiry
Tell us the model, quantity, destination market and any branding or packaging requirement. A spec sheet or drawing helps but is not required to start.
-
02
Our sales team contacts you
A named account manager follows up by email or WhatsApp, confirms the specification and clarifies anything missing before pricing.
-
03
Quotation
You receive a written quotation with unit price, MOQ, packing details, lead time and the trade term you asked for. Entry, mid and premium build levels can be quoted side by side.
-
04
Sample approval
We send a sample for finish, function and packaging sign-off. Branded samples are produced once artwork is confirmed.
-
05
Production and shipment
Mass production starts after sample approval and deposit. QC and inspection run before loading, then the order ships to the agreed port.
OEM and ODM to your specification
We develop to a brief. Send a reference model, a drawing or simply the price band and market you are targeting, and we will propose what fits. Entry, mid and premium builds are all available from the same factory.
- Your logo on product, carton and documentation
- Private-label packaging and manuals
- Custom finish matched to your standard
- Custom dimensions and tooling where volume supports it
- Product development from your reference or price target
- Destination-market documentation prepared on request
The SN6448 is pressure-molded from roughly 80% natural quartz aggregate bound in acrylic resin, producing a dense, non-porous quartz composite sink that resists heat to about 535F (280C), scratches, and chemical staining. Color runs through the full thickness in Matte Grey, so daily abrasion never reveals a contrasting core. The integrated single-bowl form eliminates seams where bacteria collect, making it a durable specification for kitchens, prep areas, and light-commercial use. Browse the full quartz sinks range to align finishes and bowl configurations across one project.
This 25" x 19" x 12" integrated sink installs as a drop-in over a 27"-plus base cabinet, with the molded rim providing a finished overlap on stone, laminate, or solid-surface counters. The 305 mm bowl depth contains splashing and hides stacked cookware, while the smooth radius corners wipe clean with a soft cloth and mild detergent. Avoid leaving acidic residue to dry on any quartz surface. Sizing, weights, and rough-in dimensions for the whole quartz sinks line are supplied for trade ordering and site coordination.
As the manufacturer, SANIKB produces the SN6448 for private-label and contract programs. We customize finish color, bowl dimensions, drain placement, faucet ledge, and retail packaging to your spec, with low MOQs for distributors, hospitality groups, and builders. Request material samples, branded spec sheets, and tiered project pricing to standardize a quartz sink program across multiple SKUs and finishes.
