Vesel faucets are taller than the average faucet and most often require only one hole for mounting. They are taller so that they can come up over the vessel sinks which are often mounted on top of the countertop. Vessel sink faucets are available in various heights to accommodate the variable heights of vessel sinks.
Using a vessel faucet can also give you more space on the vanity top because of the single mounting design. Due to the popularity of vessel sinks the selection of vessel faucets is quite broad and varied.
When selecting a vessel sink faucet keep in mind the mounting of the vessel sink. The height of the installed faucet needs to clear the edge of the mounted sink and leave enough space for hand washing. Also the reach of the faucet spout should match the vessel so that you can avoid problems with splashing water.
Installing a vessel sink faucet:
- Plan the mounting location: If the vanity countertop has not been pre-drilled you will need to decide the location of the faucet in relation to the sink. The water should flow into the center of the vessel to prevent splashing. Mark the location of the faucet with pencil as a guide for drilling. Make sure hole is the right size for your vessel faucet body to fit through and small enough to be covered by the faucet trim. The standard size hole for most faucets including vessel faucets is 1 ⅜” but check the manufacturer instructions for size specifications.
- Position the faucet: Having a second person to hold the faucet in the right position really helps when installing a vessel faucet but it can be done solo. Apply Plumber’s putty to the gasket on the bottom of the spout that will sit on the countertop. Insert the faucet into the mounting hole and align the spout.
- Secure the mounting: While holding the faucet in place reach under the counter to place the washer and mounting nut onto the faucet. Use pliers to tighten the mounting nut. Tightening the mounting underneath the counter often turns the faucet body as well so continue to hold it as you tighten. Check the alignment of the faucet and make adjustments before moving on to the next step.
- Connect the water lines: Many faucets have ⅜” flexible water lines built in. If the shut off valves under your sink are ⅜” then you have it made, if not you may need some sort of adapter to convert to the faucet flex line size. You can also just change the shut off valves to ⅜” that way everything is new. Connect the flexible lines from the faucet to the shut off valves. Use a two pliers or wrenches to tighten the flex lines; one to hold against the valve and the other to tighten.
- Test for leaks: Turn the water supply on by opening both shut off valves. Test the faucet by running both hot and cold water. Tighten anything that may be leaking. Confirm that you connected the hot and cold water lines to the right sides and switch them if necessary.
