Overflow Cap - Products
The sink overflow cap is the small trim piece that covers the overflow slot on a bathroom basin, hiding the opening and finishing the look in a matching metal. Moonshine Bath's overflow caps come in finishes that coordinate with our drains and faucets — an easy detail that ties the basin together.
Replacing a missing or mismatched cap instantly tidies a sink. Each overflow cap ships free across North America, leaves the warehouse within 24 hours on weekday orders before 2 PM EST, and is covered by our price match + 10% beat guarantee.
Frequently Asked Questions
What does a sink overflow cap do?
It's a decorative cover that snaps or clips over the overflow opening on the front of the basin, concealing the hole while still letting the overflow vent work. It's mainly cosmetic.
Are overflow caps a standard size?
Most fit the standard overflow slot found on common bathroom basins. Check your basin's overflow shape (oval or round) against the cap to be sure it seats neatly.
