A Gray Top-Mount Quartz Sink for Any Kitchen Countertop

This Karran single-bowl drop-in kitchen sink installs into any countertop material and brings a neutral gray quartz surface to a kitchen that needs a workhorse basin with contemporary color.

Key Features

• Top-mount installation that drops into any countertop material, including laminate, solid surface, granite, and quartz.
• Single bowl configuration with a 29-inch interior length and 9-inch depth for handling large pots, sheet pans, and oversized cookware.
• Gray quartz composite construction for a matte neutral tone that coordinates with a wide range of cabinet and countertop combinations.
• 33-inch cabinet minimum with a 3-1/2-inch drain opening for a standard disposal or strainer fitting.
• cUPC and IAPMO certified for code-compliant residential kitchen installs.

One Basin, No Divider

A single uninterrupted bowl lets the sink handle the full range of kitchen tasks without a center divider cutting into usable space. The 9-inch interior depth clears the rim by enough to submerge a stockpot or rinse a full baking sheet flat. There is no second basin to limit the left-right reach of what fits. For a kitchen where the sink is a workhorse rather than a divided workflow station, that unbroken interior is the practical choice.

Gray Quartz on Any Counter

The gray finish is a muted, mid-tone neutral that reads neither warm nor cool, which gives it flexibility across cabinet wood tones, countertop colors, and hardware finishes. It works as well against a white shaker cabinet run as it does in a darker, more layered kitchen palette. The quartz composite body carries the color all the way through the material, so chips and scratches at the rim or bowl corners do not leave a contrasting underlayer visible. Top-mount installation means the sink rim rests on the countertop surface and is secured from below, so the countertop material does not need to be fabricated for an undermount profile. Laminate, tile, solid surface, granite, quartz, and most other countertop materials all work without special edge treatment.

Where This Sink Fits

This is a practical choice for a kitchen renovation where the countertop is staying in place and an undermount installation is not on the table. Drop-in sinks reuse the existing countertop cutout when the dimensions line up, which makes them common in budget-conscious remodels, rental upgrades, and situations where the cabinet run and countertop are sound but the old sink needs replacing. The gray finish also suits spaces where a black or white sink would read too sharp against the surrounding palette, and designers specifying a more grounded, organic kitchen aesthetic often find gray quartz easier to integrate than a high-contrast option. Contractors sourcing sinks for multi-unit builds appreciate the cUPC and IAPMO certifications, which satisfy residential plumbing code requirements without additional documentation.
