Undermount Bathroom Sinks for Vanities

Undermount bathroom sinks create a clean, seamless vanity surface and are widely used in modern bathrooms. Compared with top-mount designs, undermount bathroom sinks make daily cleaning easier and highlight the stone or solid-surface countertop. SANIKB offers single-bowl and double undermount bathroom sink options for standard vanity cabinets.

Rectangular Undermount Bathroom Sinks

Rectangular undermount bathroom sinks are popular for contemporary projects and double-sink layouts. Our rectangular basins cover common sizes such as 18" x 13", 19" x 16", and 20" x 15", supporting both single-hole and widespread faucet configurations. Straight lines and deep bowls provide more usable washing space without increasing the countertop footprint.

Oval & Round Undermount Bathroom Sinks

Oval undermount bathroom sinks remain a classic choice for residential bathrooms and hotel projects. SANIKB provides oval and round undermount bathroom sinks in compact and standard dimensions, fitting narrow vanities while maintaining comfortable bowl depth. Smooth curves help water drainage and reduce splash, making them ideal for everyday use.

Square & Compact Undermount Bathroom Sinks


For small bathrooms and guest powder rooms, compact and square undermount bathroom sinks are highly efficient. Our small undermount bathroom sinks are designed for tight spaces while still meeting standard faucet placements and overflow requirements. These models are suitable for narrow countertops and small vanity designs.

Materials for Undermount Bathroom Sinks


Most SANIKB undermount bathroom sinks are made from vitreous china ceramic with a glazed surface for stain resistance and easy cleaning. We also support custom designs in special finishes such as matte white, black, or colored options to match different bathroom styles. The durable material structure is suitable for long-term use in high-traffic projects.

Sizes and Dimensions for Undermount Bathroom Sinks


Project buyers often search by size—from 10" mini undermount bathroom sinks to 24–30" large undermount bathroom sinks. SANIKB provides clear dimensions including overall size, bowl size, and required cut-out size, helping fabricators with precise countertop cut-outs. Standard undermount bathroom sink sizes are compatible with most vanity and cabinet layouts used in global markets.

Undermount Bathroom Sink Installation on Stone Countertops

Undermount bathroom sinks are frequently installed under granite, quartz, and solid-surface countertops. Our basins are designed with reinforced rims and clip positions to support adhesive and bracket installation. Proper installation ensures long-term stability and prevents water leakage between the sink and countertop edge.
