Faucet Installation Cost Calculator

What is included in the estimate

Here is how the default bathroom faucet project breaks down in the calculator, so you can see where the money goes:

On a basic faucet, plumber labor and the trip charge together are about as large as the faucet and parts. That is why a cheap faucet does not always mean a cheap installation.

Plumber labor costs

A straightforward faucet replacement usually takes about one to two hours, including taking out the old faucet. The calculator assumes planning labor rates of $85, $115 and $150 per hour for the Budget, Standard and Premium levels at an average U.S. market, plus a one-time service-call charge. A cramped under-sink cabinet adds time, because the plumber works in a tight space, often lying on their back. Installing several faucets in one visit is estimated at less time for each additional faucet because the plumber is already set up.

Scheduling matters too. Work within 48 hours adds about 15% to labor, and emergency or after-hours calls add about 50%. If you have a leak, shut off the water at the valve under the sink and book a standard appointment when you can.

Removal and disposal costs

Removing an old faucet usually takes about 15 minutes when everything is in good shape and is shown separately from installation. If the mounting nuts and fittings are corroded or stuck from mineral buildup, the calculator adds extra labor for each faucet. Haul-away is a small separate line. If there is no existing faucet, both lines are removed from your estimate.

Common extra costs

Several add-ons can raise the price. Old shut-off valves and supply lines are often replaced during a faucet installation if they are corroded, leaking or hard to turn. A damaged drain assembly may need to be replaced at the same time. Drilling extra holes in a stone countertop usually calls for a specialty contractor or fabricator and appears as an equipment cost. If there is no hot and cold supply where you want the faucet, such as a new bar sink, pot filler or wall-mount faucet, the plumber has to run new supply lines, which is the largest extra. Each of these appears as an option in the calculator so you can see how much it adds.

Permit considerations

Replacing a faucet with the same type in the same spot generally does not need a permit. Running new supply lines, installing a pot filler or opening walls for a wall-mount faucet is more likely to require one, and rules vary by city and county. The permit option in this calculator is an allowance for planning only. It is not your municipality's actual fee, so check with your local building department or ask your plumber whether a permit applies.

Budget vs. standard vs. premium

Budget is a sensible choice for a rental, a guest bath or a simple like-for-like swap. Standard fits most family kitchens and bathrooms and balances price with serviceable parts. Premium makes sense for a remodel, a primary bathroom or a kitchen faucet with advanced features. Compare the three levels against what matters most to you: finish, durability, a sprayer, a touchless sensor or a warranty.

Regional pricing differences

Labor rates differ across the country. Large metro areas and high-cost coastal markets generally cost more than rural areas and small towns. The Labor market selector applies an adjustment to labor, disposal, equipment, repairs and permits, while leaving the faucet price unchanged, since a faucet costs about the same at most retailers. These are broad planning adjustments, not local price data.

Replace the faucet or repair it?

Repair when the faucet drips because of a worn washer, cartridge or O-ring and the finish and body are in good shape. Parts are inexpensive. Replace when the faucet is corroded, the finish is flaking, the handle or body is cracked, parts are discontinued, or a repair would cost close to the price of a new faucet. A new faucet also makes sense if you want a different style, a pull-down sprayer or a touchless sensor.

DIY or hire a plumber?

Replacing a basic faucet at an accessible sink is a manageable job for handy homeowners. The difficult parts are working in a tight cabinet, freeing seized nuts, and getting the connections watertight. A leak under the sink can go unnoticed and damage the cabinet. Hire a plumber if the shut-off valves are stuck or leaking, you are adding a new supply line, installing a wall-mount faucet or pot filler, or the sink is a stone countertop that needs drilling.

How to budget and avoid unexpected costs

• Count the holes in your sink or countertop before you buy. A faucet that needs more or fewer holes than the sink has will not fit without a deck plate or a different faucet.
• Check that the shut-off valves under the sink turn and do not leak. Budget for new valves if they are old.
• Ask whether the quote includes the faucet, supply lines, removal and disposal of the old faucet, and any trip or minimum charge.
• Clear out the cabinet under the sink before the plumber arrives. It saves time and reduces labor.
• Install several faucets in one visit when you can, so you pay one trip charge.

Questions to ask a plumber

• Is the quote itemized, and does it include removal and disposal?
• Do you supply the faucet, or should I buy it? Who is responsible if it arrives damaged or does not fit?
• What happens if the shut-off valves or supply lines are corroded or need replacing?
• Is there a service-call or minimum charge?
• Is a permit needed, and is it included?
• What warranty do you offer on the installation?
