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.

01 / FORM

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.

02 / MOUNT

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

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.

Matte Grey

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.

Material and Build: Single-Piece Quartz Composite

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.

Installation and Daily Use

For this 25" x 19" x 12" integrated sink, confirm the mounting method, rim position and 27"-plus base cabinet guidance on the current installation drawing for the selected stone, laminate or solid-surface counter. Allow for the listed 305 mm depth and drain assembly in the cabinet layout. 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.

OEM and Custom Orders

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.

FAQ

Is the SN6448 a true integrated sink or a separate bowl?

The SN6448 is a one-piece integrated kitchen sink molded from a single quartz composite blank, so the bowl and rim form a seamless unit with no welds or silicone joints to trap grime. At 25" x 19" x 12" (635 x 482 mm, 305 mm deep), it suits compact prep stations and island runs. It ships as part of our wholesale quartz sinks range for distributors specifying a continuous, easy-clean surface.

Does the Matte Grey finish stain or show water marks in hospitality use?

The Matte Grey surface is colored all the way through the quartz composite, not coated, so scratches and chips do not expose a different base color. Its non-porous structure resists coffee, wine, and limescale staining, and the matte texture hides water spots far better than gloss. For mid-tone specs across a project, compare it with the other shades in our quartz sinks collection.

What countertop cutout and depth do I need for the SN6448?

Use the current SN6448 template to confirm the cutout and mounting method for the 25" x 19" footprint. Check the 27"-or-wider base cabinet guidance and the listed 12" (305 mm) depth against the installation drawing, including drain clearance below. Confirm the rim position and edge detail with the countertop fabricator. Spec sheets and CAD cutouts are available on request through our quartz sinks page for builder and dealer quoting.
