Karran White Quartz Vanity Sink for a Clean, Seamless Bathroom Counter

The Karran Q-306 is a single-bowl oval quartz vanity sink in White that mounts beneath laminate or solid surface countertops for a smooth, uninterrupted counter surface above the bowl.

Key Features

• White quartz composite construction gives the sink a consistent, bright color all the way through the material.
• Undermount installation into laminate or solid surface countertops, with no visible rim at the counter surface.
• Single oval bowl with a 17-inch interior length, 13-inch interior width, and 5-1/2-inch depth.
• Requires a minimum 21-inch cabinet width for proper fit and installation.
• 1-3/4-inch drain opening sized for compatible vanity drain fittings.
• cUPC certified to meet North American plumbing standards.

A Vanity Sink Built for Laminate and Solid Surface Counters

Most quartz undermount sinks are specified for stone countertops, but this Karran sink is engineered specifically for installation into laminate and solid surface counters. That makes it a practical choice for bathroom vanities where a laminate or solid surface top is the countertop material, and where an undermount look is still the goal. The sink mounts beneath the counter so the surface runs cleanly to the bowl edge with no lip or rim to interrupt it.

Quartz Composite in White

The Q-306 is made from quartz composite, a dense material that carries its White color uniformly through the body rather than as a coating or veneer on top. The oval bowl form keeps the profile soft and works naturally in bathroom settings where hard rectangular lines are not the design intent. White is a straightforward finish choice that reads as neutral against most cabinet colors and countertop patterns, and it coordinates easily whether the vanity is traditional, transitional, or contemporary.

Where This Sink Fits

This sink is the right specification when the vanity countertop is laminate or solid surface and an undermount installation is required. It suits a primary bathroom vanity, a guest bath, or a powder room where the 19-inch overall footprint fits the layout. The minimum cabinet width required is 21 inches, so confirm the base cabinet before ordering. Because it is undermount only and is designed for laminate and solid surface substrates, it is not the right choice for a ceramic tile, stone, or concrete countertop installation.
