Quartz sinks resist scratches better than stainless steel, maintain color consistency, and require minimal maintenance. However, they are heavier and require proper support during installation—SANIKB provides full technical guidance for project contractors.

Frequently Asked Questions

What is a quartz composite sink made of, and how does it differ from ceramic?

A quartz composite sink is formed from roughly 80% crushed natural quartz bound with acrylic resin, producing a dense, non-porous, scratch-resistant basin available in through-color finishes. Unlike a glazed ceramic body, the color runs through the full thickness, so surface chips stay far less visible. For buyers weighing both materials, our ceramic sink range offers a comparison point on weight, glaze finish, and price per unit.

Do you supply quartz undermount sinks with cutout templates for installers?

Yes. Every quartz undermount sink ships with a printed mounting template, and we provide CAD cutout files on request so fabricators can pre-route countertops before delivery. This is standard for our trade and project accounts placing repeat orders across multiple installation sites.

What are the main quartz kitchen sinks pros and cons for a hotel or builder order?

The pros are heat tolerance, stain and UV-fade resistance, and a non-porous surface that requires no sealing over its service life. The cons are higher unit weight, which calls for adequate cabinet bracing, and a higher upfront cost than entry-level stainless. We list full specifications per SKU so your team can plan support and freight.

Are quartz kitchen sinks heat and stain resistant enough for commercial kitchens?

Our quartz kitchen sinks resist heat from typical cookware and hold their finish against acidic foods, coffee, and tea without staining, because the surface is non-porous and does not absorb liquids. For commercial and hospitality buyers we can supply test data on heat thresholds and abrasion resistance to support your specification sign-off.

Do you offer wholesale pricing and MOQs on quartz composite sinks?

As a direct manufacturer we set tiered wholesale pricing by container volume, with MOQs and lead times confirmed at quote stage for distributors, builders, and hospitality groups. We can also bundle quartz sinks with coordinating fixtures and other sink materials in a single shipment to consolidate freight.

Start from the countertop detail

Six quartz kitchen sink starting points by mounting method

The mounting type is usually fixed by the countertop drawing before color is discussed. Use these six quartz sinks to find the size and type that fits your project needs, then compare the rest of the products in the table further down.

Material questions buyers raise

Quartz composite sink colors and countertop questions for a project order

Color is the widest choice in this quartz composite range: the 16 quartz composite sinks come in various colors: Matte Black, Black, White, Gray, Matte Grey, Blue and Matte Green, and OEM colors are offered to private-label buyers. If a project needs a shade outside that list, raise it in the first request so the quote can address it.

If your customers need weight, care and cleaning guidance or installation hardware details, ask for them with the quote for each model. Ask for the drawing or spec sheet before planning cabinet work around the larger 33" sinks; SN3321-MB and SN3319-MB already have a spec sheet file attached.

Countertop pairing is the other common question. The range splits into 8 drop-in, 5 undermount and 3 apron-front models, so the countertop detail usually narrows the shortlist before color. If a project needs both a quartz sink and a stainless steel sink, the wider kitchen sink range can be quoted on the same order, so a distributor can pick a stainless steel sink line to sit beside the quartz composite line.

For undermount and apron-front quartz composite sinks, tell us whether the countertop is granite, quartz or another stone, and send the cutout drawing if the fabricator already has one. Mounting details can differ by countertop and sink type, and the drawing for each model is the way to confirm them before the order is placed. Use this guide with the product pages: every quartz composite sink listed here has its own drawing or spec request path, and pricing is quoted per order rather than published.

Two quartz composite sinks sharing a width can still differ front to back by several inches, so compare all three dimensions with the cabinet and countertop drawing, not the width alone. Checking all three figures is the easiest way to ensure the right type of sink is ordered.

Matching models to the account type

Who orders quartz kitchen sinks from this range

Distributors and importers

Matte Black runs across 8 drop-in and apron-front models, which makes it the simplest color to stock deep. White, Gray and the colored finishes can be added model by model at 50 pcs each.

Home builders and multi-family developers

Repeat sizes keep the line count down on home projects: SN8549, SN8549B and SN8456 share one published drop-in size, and SN8448 and SN8448D share one published size across undermount and apron front.

Countertop fabricators

For undermount cutting work in granite or quartz, the five undermount quartz composite sinks run from the 23" SN5844 to the 33" SN8344 and SN8448; drawings can be requested per model before granite, quartz or other stone tops are cut.

Private-label brands

OEM colors, mold development, branded packaging and samples are available to qualified buyers; see the OEM and ODM service page for the process.

Writing a quartz sink quote request

How to request a quote for quartz composite kitchen sinks

  1. List model codes with finish

    Name each model, such as SN8549 White or SN8549B Matte Black, rather than a description. For SN8448, state the color you need.

  2. Confirm mount and countertop

    Note drop-in, undermount or apron front, and the countertop material (granite, quartz or another stone), so the cutout and mounting details are confirmed with the quote.

  3. Give quantity per model

    MOQ is 50 pcs per model. A mixed order across several models is quoted per line, with pricing set per order.

  4. Ask for drawings or samples

    Spec sheets are attached to SN3321-MB and SN3319-MB; request drawings for the other quartz composite sinks and samples before a bulk run, so the installer can see how to install each sink type.

  5. Add branding needs

    For private label, include logo, packaging and any custom color so the OEM review starts with the first reply. Written replies come within 12 business hours.
