Glass Bathroom Sinks
Glass bathroom sinks bring a sculptural, jewel-like quality to the vanity that no other material can replicate. Because glass is non-porous, the surface never absorbs soap residue, toothpaste, or hard water minerals — a quick wipe with a soft cloth restores the original shine. Most bowls in this collection are made from tempered glass, which is heat-treated to resist thermal shock and fractures into small, blunt pieces if it ever does break.
Browse over 350 designs in clear, frosted, and richly colored finishes — including blue glass vessel sinks for coastal and spa-inspired baths. Compare against porcelain or natural stone options, or return to the full bathroom sinks catalog.

Frequently Asked Questions
Will a tempered glass sink crack from hot water?
Tempered glass is heat-treated to handle thermal swings up to roughly 300°F, so normal hot tap water poses no risk. However, repeated extreme contrasts — like pouring boiling water into a cold basin — can stress the glass over years of use. Run hot water with the cold tap partially open to temper the shock, and avoid setting hot styling tools like curling irons directly on the rim.
How do I keep a glass sink free of water spots?
Because glass is non-porous, mineral deposits sit on the surface rather than absorbing in — they look worse but wipe away easily. Dry the bowl with a microfiber cloth after heavy use, and clean weekly with a 50/50 white vinegar and water solution to dissolve hard water film. Skip abrasive pads and powdered cleansers, which can leave fine scratches that dull the finish permanently.
What faucet works with a glass vessel sink?
Glass bowls almost always install as vessel sinks, sitting 5–6 inches above the counter. You'll need a tall vessel faucet with a spout that clears the rim by at least 1 inch and reaches roughly to the center of the basin. Wall-mounted faucets are another popular pairing — they leave the glass fully visible and avoid drilling extra counter holes near the bowl.
Can a glass sink support its own weight on a standard vanity?
Yes. A typical 16–18 inch tempered glass bowl weighs 15–25 pounds — well within the load any vanity counter can handle. The bigger concern is the cutout: drill a clean 1.75 inch drain hole and seal the underside with clear silicone to prevent moisture from creeping into wood substrates. Use an extended-thread pop-up drain assembly designed specifically for vessel installations.
Do glass sinks have an overflow drain?
Most glass vessel sinks do not include an overflow hole, which is part of why the bowl can stay so visually clean. That means you'll need a non-overflow (also called grid or open) pop-up drain — a standard overflow-style drain will leak. Check product specs before buying drain hardware separately, and avoid leaving the faucet running unattended with the stopper closed.
