Karran Quartz Sink QT-825 Series defines a compact top mount single bowl bar and prep sink that suits tight layouts while still handling everyday use. This quartz sink is constructed with 80% natural quartz crystals and pure acrylic resin, so the bowl structure provides outstanding durability over a long lifespan where repeated use and minor impacts are common. The quartz composite material is highly resistant to stains, scratches, abrasions, and impacts, which helps the bisque finish maintain its visual appearance after frequent cleaning in busy bar or secondary prep stations. The design features an 8 inch deep bowl, creating usable working depth for barware and small kitchenware without consuming extra cabinet height. This single bowl configuration focuses the available space into one functional basin, which simplifies cutting the countertop opening and aligning the drain for installers planning efficient runs.
This quartz composite sink is designed as a top mount unit, so it drops into a cutout and rests on the countertop surface, which supports straightforward installation in many common countertop materials. The sink requires an 18 inch sink base cabinet, giving a clear lower-cabinet size target when laying out bar or prep runs. The bowl is 8 inches deep, which balances usable working depth with under-counter space for plumbing components. A 3-1/2 inch drain opening provides the connection point for the drain and is compatible with most garbage disposal systems, simplifying product selection on the plumbing side. The sink is pre-drilled with one faucet hole, and additional holes are marked underneath, so installers can locate optional hole positions as needed during the fabrication stage.
This Karran quartz sink sits in the quartz sinks class and is identified as QT-825-BI, which positions it as a bar and prep sink rather than a full-size primary kitchen basin. The minimum 18 inch sink base cabinet requirement aligns it well with compact bar bases, island return sections, or small secondary prep zones where space is limited. The 8 inch deep single bowl design creates enough room to handle glassware and smaller kitchenware, so it supports rinsing, quick prep, and cleanup without demanding a larger cabinet. The engineered noise reduction that absorbs vibration and minimizes noise helps it suit entertainment areas, as the sound of running water and dish contact remains more controlled.
The quartz composite construction with 80% natural quartz crystals and pure acrylic resin gives a stable, rigid bowl structure, so the rim sits securely as a top mount sink once the countertop cutout is done to size. Heat resistance up to 535 F helps the bowl tolerate thermal shifts from hot water or cookware, supporting long-term service without damage in normal bar or prep duty cycles. High resistance to stains, scratches, abrasions, and impacts helps the bisque finish remain consistent, which reduces the need for surface refinishing over the lifespan of the installation. The 3-1/2 inch drain opening dimension ties directly to common drain and disposal sizing, so plumbing components align with standard expectations. The pre-drilled single faucet hole simplifies faucet placement, and the additional marked holes underneath give clear reference points when a specific faucet or accessory configuration is required on site. The approximate 20 lb weight keeps handling manageable during installation while still reflecting the density of a quartz composite bowl.
The Karran QT-825-BI sink uses quartz composite constructed with 80% natural quartz crystals and pure acrylic resin, giving a hard, dense surface suited to regular bar and prep use.
The 8 inch deep bowl provides enough depth to handle barware and small kitchenware while still fitting comfortably above plumbing in an 18 inch sink base cabinet.
The Karran quartz bar prep sink requires a minimum 18 inch sink base cabinet, which defines the lower cabinet section where it can be installed in a layout.
The QT-825-BI sink has a 3-1/2 inch drain opening, allowing use with most garbage disposal systems and matching standard drain components in bar and prep installations.
This top mount single bowl quartz sink is pre-drilled with one faucet hole, with additional holes marked underneath to guide optional on-site drilling when needed.
The sink is engineered to absorb vibration and minimize noise, so water flow and dish contact generate less sound in bar or open kitchen environments.
The Karran Quartz Sink QT-825 Series QT-825-BI combines a compact 8 inch deep single bowl with quartz composite construction, supporting bar and prep tasks in tight spaces. The top mount format, 3-1/2 inch drain opening, and pre-drilled faucet hole streamline layout and hook-up choices. Heat resistance up to 535 F and resistance to stains, scratches, abrasions, and impacts help the bisque finish stay consistent through everyday use. When an 18 inch sink base cabinet is available and a durable bar or prep sink is needed, this model offers defined dimensions and material performance for straightforward planning.
