Quartz Undermount Sink
Quartz Composite & Granite Composite Materials
SN8448B is constructed from quartz composite using natural granite, quartz, and engineered sand. This composite structure supports quartz sinks and granite sinks applications where durability matters. The surface is silky smooth and highly resistant to scratches, stains, chips, and cracks, offering long service life compared with many other kitchen sink materials.
Undermount Sink Design, Edges & Underside
This undermount sink is designed for installation under quartz or granite countertops. Reinforced edges and a stable underside improve fit and reduce installation issues. The construction allows easier access during installation and maintenance while maintaining a clean kitchen appearance.
Single Bowl Layout, Space & Color Options
SN8448B is a single bowl sink with ample space for daily kitchen use, bar prep, or utility areas. While not a double equal bowl or double bowl sink, alternative configurations are available as project references. Rich colors including white, black, gray, brown, and mocha support décor matching and design flexibility.
Built to Last, Hygiene & Warranty Support
Quartz composite sinks are built to last and designed to last a lifetime in professional kitchens. The non-porous surface supports hygienic use by limiting water absorption and helping reduce the spread of germs. SANIKB provides warranty, documentation, and reference files for B2B and OEM customers.
Single Bowl, 33 Inch
One undivided bowl inside an 838 mm body
The published body for SN8448 is 838 × 482 × 254 mm and the bowl carries no divider. What the record does not give is a finish, and that is the first thing to settle.
Single bowl, no divider
Tag and specification both record a single bowl. Anyone selling trays or racks with the sink should size them from the drawing, not the outside dimension.
Undermount under a solid top
Mount is listed as undermount, so the worktop carries the visible edge. Counter material and cutout quality become part of the specification.
It is listed with the rest of the bodies under undermount kitchen sinks.
Fit & Clearance
838 × 482 mm under the counter, one open bowl
On an undermount body the questions land on the fixing and the reveal.
Published plan is 838 × 482 mm. Cabinet interior width, rather than the nominal cabinet size, is what decides whether the body goes in.
Neither the fixing method nor the reveal appears in this data. Settle both from the factory drawing before the top is cut, because a cutout cannot be taken back.
The drawing belongs at quotation stage, not after the worktop is ordered.
Construction & Finish
Quartz composite with the finish left open
The specification names a material for SN8448 and stops. No colour is recorded against it.
Material stated, finish not stated
Quartz composite is the published material. With no finish in the data, colour has to be fixed by the purchase order and cannot be inferred from photographs.
Write the finish into the order and attach the approved sample reference to it. A purchase order that omits it leaves the most visible variable open.
An unstated finish is a commercial risk. Close it before the proforma.
Compliance
Two blanks to close before SN8448 is specified
The finish reference belongs in the same written confirmation as the drawing. Ask for both against the order number rather than the listing.
The record lists no certification or listing mark, and it lists no finish. Neither gap should be filled in by assumption.
Send the destination market with your enquiry. We will confirm in writing what documentation can be supplied, together with the finish the order will be produced in.
Procurement
What a quotation for SN8448 has to cover
An order for this model stays incomplete until the colour is named.
Quantity, finish and destination are the three lines a quotation needs. If a first order sits below the published figure, say so in the enquiry.
A colour we do not already run becomes a development item rather than a stock line. Raise it through the SANIKB OEM and ODM program.
Include these details with the RFQ
- Finish this batch is to be produced in
- Quantity against SN8448 for the first order
- Market the documentation reply should cover
- Top material the body will be fixed under
- Fixing method and the reveal preferred
- Colour sample reference held against the order
- Waste and accessory scope
- Own-brand labelling and container split
The quotation confirms the lead time and the minimum that apply to the order in hand.
This undermount sink is molded from quartz composite, a blend of natural quartz granules and resin that is dense, non-porous and resistant to scratches, heat and staining. Pigment runs through the full thickness, so the finish wears evenly and hides minor knocks better than coated metal. The 33" x 19" x 10" single bowl is built for daily commercial and residential kitchen use. Browse the full quartz sinks collection for matching colors and bowl configurations.
At 33" x 19" x 10" (838 x 482 x 254 mm), this sink fits a standard 36" base cabinet and mounts under the countertop with clips and adhesive, leaving a clean exposed counter edge. Because quartz composite is heavier than stainless, confirm the cabinet and counter support against the weight spec we supply. Cutout templates and mounting hardware ship with the sink. See the quartz sinks collection for additional install drawings.
We manufacture quartz composite sinks for wholesale and private-label supply to distributors, cabinet makers and builders. OEM options include custom colors, bowl sizes, drain placement, packaging and branding, with MOQ and lead time confirmed per program. Send your specification and volume for a quote.
