Single Hole Bathroom Faucets for One-Hole Sinks
Single hole bathroom faucets are designed for sinks and countertops drilled with just one mounting opening, giving you the cleanest, most uncluttered deck possible. Because the spout and control mechanism share a single body, these faucets free up counter space around the basin and make wiping down the area quick and easy.
If your existing sink has three pre-drilled holes, you can still use a single hole model by pairing it with a deck plate (escutcheon) that covers the outer holes — most manufacturers offer one as an add-on in the matching finish. Browse the full bathroom faucets collection if you need a different drilling configuration, or filter by finish and style to narrow the selection.
This page brings together nearly 200 one-hole designs ranging from minimalist contemporary spouts to vintage-inspired bridge faucets, so you can match the look of the rest of your bathroom hardware.

Frequently Asked Questions
Can I install a single hole faucet on a sink with three holes?
Yes. You'll need a deck plate (also called an escutcheon) that spans the standard 8-inch hole pattern and covers the two outer openings. Most single hole faucets either include a deck plate or offer one as a matching accessory in the same finish. Without it, the unused holes will remain visible around the faucet base.
Are single hole faucets always single-handle?
The vast majority are. Because there's only one mounting opening, the spout and a single lever are combined into one body, with the lever controlling both flow and temperature. A small number of designs use a joystick or rotating top, but you won't find traditional two-handle hot/cold setups on a true single hole faucet — those require additional drillings.
What size hole does a single hole faucet need?
Standard single hole faucets require a mounting opening of approximately 1-3/8 inches (about 35 mm) in diameter. Vessel sinks and most modern one-piece basins come pre-drilled to this spec. Always check the individual faucet's installation sheet, since a few oversized contemporary models call for a 1-1/2 inch opening.
Do single hole faucets work with vessel sinks?
Yes, but height matters. A vessel sink sits on top of the counter, so a standard short single hole faucet may not clear the rim. Look for a tall single hole faucet (typically 10-14 inches high) labeled as a vessel faucet, or choose a wall-mounted option that bypasses the counter entirely.
Is a single hole faucet easier to install than a widespread?
Generally yes. With only one mounting nut to tighten and two supply lines (often pre-attached), a single hole installation takes less time and requires no aligning of separate spout and handle pieces. Widespread faucets need three connections plus an underbody linkage between hot and cold valves, which is more work in the tight space under a vanity.
