Karran Q-306-GR Gray Quartz Vanity Sink Details

Karran Q-306-GR gray quartz vanity sink is a single bowl undermount model that uses a 19 inch by 15 inch external bowl size to define the cutout footprint, which matters when laying out a bathroom vanity top. The internal bowl dimensions of 16-1/2 inches by 13 inches by 6 inches create a defined washing area, so installers can visualize depth and width when coordinating cabinet, drain location, and backsplash spacing. This quartz sink is manufactured from 80% crushed quartz plus 20% acrylic resin, which creates a hard composite structure that supports long-term daily use in a bathroom environment. The completely nonporous surface prevents bacteria build up, which simplifies routine cleaning in projects that prioritize hygiene. The gray quartz material and satin finish present a consistent look across the bowl, which helps when matching to surrounding countertop materials in a coordinated design.

Quartz Sink Features That Support Bathroom Projects

• The 19 inch by 15 inch by 5-1/4 inch external bowl dimensions define the required cutout size, which helps plan clearances to faucet, wall, and cabinet rails.
• The 16-1/2 inch by 13 inch by 6 inch internal bowl dimensions provide a defined basin volume, which supports predictable splash control and usable space at the vanity.
• Construction using 80% crushed quartz plus 20% acrylic resin creates a solid composite body, which supports long-lasting shape and structural stability in normal bathroom use.
• The sink is suitable for undermounting to laminate, solid surface and granite, which allows one bowl design to be specified across multiple countertop materials on a project.
• The sink is guaranteed not to stain or crack from thermal shock and withstands temperatures of up to 530 F, which handles exposure to hot water and heated grooming tools at the vanity.
• The completely nonporous surface that prevents bacteria build up supports easy cleaning routines, which is valuable in multi-user or high-traffic bathroom installations.

Undermount Installation And Faucet Layout Options

The Q-306-GR gray single bowl vanity quartz sink is suitable for undermounting to laminate, solid surface and granite, which lets fabricators use consistent mounting methods across different top materials in a job. This sink works with faucet deck type sinks that accept 1 hole, 2 hole and 3 hole faucet setups, which gives planners flexibility to choose single-handle or widespread faucet configurations without changing the bowl model. All external dimensions are approximate to 1/4 inch, which provides a clear tolerance band when laying out cut lines and templates for the opening. The satin finish allows the use of all cleansers, including abrasive scouring pads, which helps maintenance teams remove buildup without changing cleaning products.

Using This Quartz Vanity Sink In Real Projects

Where This Karran Vanity Quartz Sink Fits Best

This Karran 19 inch wide by 15 inch deep Q-306 gray single bowl vanity quartz sink fits projects where an undermount look is needed on laminate, solid surface and granite tops, which helps keep the counter surface visually clean around the opening. The internal bowl depth of 6 inches suits bathroom vanity applications that benefit from a reasonably deep basin, which helps manage water splashes while retaining comfortable reach from the counter edge. Because all external dimensions are approximate to 1/4 inch, fabricators can plan cutouts that respect this tolerance and still maintain consistent reveal or overhang preferences across multiple tops. The gray quartz material with a satin finish supports designs that call for a neutral, matte-style appearance, which coordinates well with many laminate patterns, solid surface colors, and granite tones. In multi-vanity layouts using the same Karran Q-306-GR gray quartz vanity sink, the consistent bowl size helps standardize plumbing rough-in positions from cabinet centers.

Details That Support Repeatable Install And Finish Quality

The Q-306 gray single bowl vanity quartz sink is manufactured from 80% crushed quartz plus 20% acrylic resin, which produces a stable composite that resists everyday bathroom impacts and supports reliable undermount bonding to laminate, solid surface and granite. The completely nonporous surface that prevents bacteria build up also resists fluid absorption, which supports uniform appearance at the bowl surface over time in recurring-use bathrooms. Since the satin finish allows the use of all cleansers, including abrasive scouring pads, facility and home maintenance staff can use a broad range of cleaning products to remove mineral deposits or cosmetic residues while preserving the working face of the bowl. The guarantee that the sink will not stain or crack from thermal shock and withstands temperatures of up to 530 F means the quartz body handles contact with hot water and heated grooming tools at the vanity, which reduces the risk of performance issues under typical bathroom conditions. The faucet deck type compatibility with 1 hole, 2 hole and 3 hole faucet setups makes this Karran quartz vanity sink suitable for a range of faucet trim packages on the same rough opening.
