How much does it cost to install a bathroom sink?

Reviewed by Cristina Miguelez remodeling expert. Written by Fixr.com.

The bathroom sink is an integral part of every home. Whether you opt for a decorative and eye-catching vessel or a classic pedestal design, the sink can make your bathroom a more functional place and enhance the room’s design. Bathroom sinks come in many shapes, sizes, styles, and layouts to suit any home or space. No matter your bathroom’s size or style, a bathroom sink can meet your needs.

The national average cost to install a bathroom sink is $500 to $1,000, with most people spending $750 on a large oval porcelain undermount sink installed with a basic 8” spread faucet. This project’s low cost is $200 for a small drop-in sink with an existing faucet and plumbing. The high cost is $2,000 for a granite vessel sink installed with a vessel faucet, grid drain, and decorative exposed plumbing.

Bathroom Sink Price

Bathroom Sink Price by Type

Bathroom sinks are available in a range of types and styles. Each type looks different, may install differently, and function differently. Some sinks have special installation needs, and others may have codes that dictate how they can be installed and used within your state. For example, you must install a grid drain with a vessel sink to pass code in many states. Because this drain may not come with the sink or the faucet, you need to purchase it separately, raising your total costs.

Bathroom sinks can be broken into two broad categories - counter-supported and wall-mounted. Drop-in, undermount, and vessel sinks require a countertop for installation. This countertop can be on a vanity, console, sink legs, or simply attached to the wall. The countertop must be cut to accept your sink’s type and size, so keep that in mind when you make your choice. While these three require a countertop, they have different costs for purchase and installation, so the cost of an undermount bathroom sink is different than a vessel sink price for installation.

Pedestal, wall-mount, and console sinks all must be attached to your wall. While pedestals and consoles have legs, these are mainly decorative and for added support. The sink must be supported by the wall, increasing your labor costs for these sinks because they may require bracing behind the sink to ensure they can be hung safely. This makes the cost to install a pedestal sink or other wall-supported sink different than the cost to install a counter-supported sink. Below are the average costs for some of the most popular sink styles and their installed costs.

Price of a Sink for a Bathroom by Material

Bathroom sinks are also available in many materials. Most sinks are porcelain and may be found in several shades of white, off-white, and a limited range of other colors. However, you can have sinks in other materials. The sink must have an overflow drain installed underneath the counter, so the sink is usually made of porcelain or acrylic because these are the easiest to get an overflow in. However, you can sometimes find a metal sink that can be dropped in or undermounted with an overflow. Otherwise, most sinks made of metal, stone, or glass must be vessels and mounted on the countertop.

Pedestal and console sinks are most commonly porcelain, but a few can also be acrylic. These sinks are more modern, with waterfall fronts or larger bases made in one piece, while porcelain pedestals and consoles are sold in two pieces that must be joined. Some materials can be more difficult to work with than others, which may raise the cost of the sink. In addition, some materials like copper, marble, onyx, and bronze can have higher price points, so a glass sink price or marble sink price may be higher than the price of a porcelain sink of the same type and dimensions. Below are the most common materials for bathroom sinks and the average cost ranges for sinks of that material.

New Bathroom Sink Cost by Number of Sinks

Bathroom sinks may be installed singly or in pairs. It is common to install two sinks in master bathrooms and larger Jack and Jill bathrooms. This allows two users to share the space at once or separately but in private areas. There are two general ways of going about this. You can install a double vanity, which is a vanity with two sink bases. It must be a minimum of 60” in length, but it is common to find them up to 72” in length. You can install two undermount, drop-in, or vessel sinks in this configuration, each with a separate faucet and plumbing.

The other method is to install two separate sinks, such as two wall-hung sinks, consoles, or pedestals. These may be on the same wall and beside one another or spread farther if the bathroom is large enough. This method is more common in classic-style bathrooms but not as common as double vanities because the double vanity gives you more storage than a pedestal or other sink.

Because each sink must be plumbed separately, installing two sinks has twice the cost. So, the cost to install two oval undermount sinks with two faucets totals $1,500, while the cost to install two drop-in sinks with existing faucets is $400. If there is only rough plumbing in place for one sink, the cost to add a second sink can be more than double because adding plumbing must be brought into the area and roughed. Installing two sinks on two different walls can have higher costs than installing two sinks on the same wall because the plumbing must be split farther up the line, increasing labor costs. Below are the average costs to install one sink versus two in the same bathroom.

Labor Cost to Install a Bathroom Sink

Bathroom sinks are installed by plumbers, who typically charge $75 to $150 an hour. It takes a minimum of one hour to install a bathroom sink if all the other plumbing is in place. This is predominately true for vessel and drop-in sinks, which require little beyond setting the sink in place and attaching the drain and P-trap. Undermount sinks require more work to secure the sink to the underside of the countertop before the plumbing can be installed to ensure it does not fall.

It can take a few hours to install pedestal, console, and wall-mounted sinks. This means labor costs typically range between $100 and $500 for a sink installation, with countertop sinks costing closer to $100 and wall-mounted sinks costing closer to $500. Costs climb with additional plumbing work, such as moving the drains or water lines, replacing the drains or water lines, or installing a faucet.

Install Bathroom Sink Plumbing

It is common to install new plumbing along with the sink. This is particularly true if the plumbing is visible. While vanities cover the plumbing, the plumbing is more exposed with console, pedestal, and wall-mounted sinks. This means it is more common to invest in better, often decorative water lines, valves, and P-traps that match the faucet’s finish. The labor for this process is $100 to $300 plus the cost of the plumbing, adding $300 to $500, depending on the size, finish, and style. Installing a new bathroom sink with new plumbing costs $750 to $1,500, depending on the sink and plumbing.

Cost to Install a Bathroom Sink Faucet by Type

It is very common to install a new faucet with your bathroom sink. The drain for your sink usually comes with the faucet, so the finishes for the two areas match. In addition, some sinks, like vessels, require a special faucet. In this case, a vessel filler, which is a tall faucet - usually a single hole - can reach over the vessel.

In the case of drop-in sinks, the sink may be drilled or have holes for the faucet to be installed with it. The sink may be drilled with a single hole, three holes a maximum of 4” apart, or three holes a maximum of 8” apart. Faucets that can be installed on a 4” spread come in two types - centerset, which is a faucet where the spot and handles are on a single mounting block, and mini-spread, where the spout and handles are smaller but sit separately, making the faucet and surrounding area easier to clean.

The most common bathroom faucet is a widespread or 8” spread faucet. This has a regular-sized spout of any shape or style with two handles 8” apart. This faucet has the most options for style and spout height and is the easiest to clean and care for. Each faucet can have a wide range of costs based on the faucet style and finish. Polished chrome is generally the least expensive, while specialty finishes like copper may be the most expensive. Below are the average costs of each faucet type and the cost of that faucet installed.

Cost to Install a Bathroom Sink and Faucet

Bathroom sinks and faucets are commonly installed together. Pedestal, wall-mount, and console sinks have holes drilled for the faucet and are not considered fully installed with the faucet. Countertop sinks can have the faucet installed separately, so this can be a single job if you only replace a sink, and the faucet is fine. However, you are likely installing the sink and faucet together most of the time. This has an average cost range of $550 to $1,500, depending on the sink and faucet type. The cost to install an oval undermount sink - the most popular type - combined with a widespread faucet has an average cost of $750 if no other plumbing work is needed.

Cost to Install a Toilet and Sink

It is also very common to install a toilet and sink together. Replacing these areas is a fast and easy way to give your bathroom a mini facelift. Or, if you are having a full bathroom remodel done, you may want to have the plumber out once to take care of these installations. The average cost to install a toilet is $400 to $800, while the cost to install a sink averages $500 to $1,000, making the total cost range for this project $900 to $1,800, depending on the sink and toilet type.

Cost to Install a Bathroom Sink and Vanity

When installing a bathroom vanity, it is common to install a sink with it. However, there can be many variations on this project, changing the costs. For example, some bathroom vanities come with a countertop that has a sink attached. All your plumber has to do is install the vanity, hook up the sink, and put in the faucet.

In other cases, you install the vanity, and then get a countertop made for the top with a cutout for your sink. After the countertop is made and installed, your plumber returns to start the sink installation process and finally comes back once more to finish it and hook up the faucet. This can make the labor cost to install a vanity and sink a very wide range because if the project can be done at once, your costs will be much lower than if the plumber needs to come back two or three times. Your bathroom sink cabinet price varies depending on the material, size, style, and whether it comes with a countertop and sink or if these must be purchased separately.

This can make the cost to install a vanity, sink, and faucet between $430 and $1,200 in labor alone, or between $1,200 and $3,500 in total, including the vanity, sink, and faucet costs. These costs do not include the countertop if you need one fabricated but may include a prefab counter if it comes with the vanity.

Bathroom Sink Replacement Cost

You may want or need to replace your bathroom sink for many reasons. If you are remodeling your bathroom, it is common to replace the existing sink to give the bathroom a fresh new look. There are also times when the older sink may begin to leak, crack, stain, or develop other issues that require it to be replaced.

Bathroom sink replacements are the least expensive when you install a new sink of the same type and shape in the same location. For example, if you are replacing a drop-in sink with a drop-in sink, the costs are around $200 in total. However, you need a new countertop, sink, faucet, and plumbing if you are replacing a drop-in sink with a vessel sink, making the sink and faucet installation between $480 and $1,850. You also have disposal costs for the old countertop - usually around $50 - and the costs of the new countertop to consider. There can be many other replacement costs associated with the project, depending on what other factors may be involved. However, the general cost range for replacement is usually close to the cost of a new sink installation of $500 to $1,000.

Replace a Pedestal Sink With a Vanity

The average cost to replace a pedestal sink with a vanity is $600 to $3,000, depending on the vanity size and type. Pedestal sinks are fairly easy to remove but may require plumbing reconfiguration for a vanity to be installed in its place. This is because most pedestal sink plumbing is tucked behind the basin, and this may need to be lowered for a vanity. Vanities come in a wide range of sizes and configurations. Some come with a countertop and sink while others need these items purchased and installed separately, raising the installation cost.

Replace a Bathroom Countertop and Sink

The average cost to replace a bathroom countertop and sink is $600 to $1,200. This assumes the vanity is already in place and you only replace the top. You may have disposal costs for the old top and sink, depending on what they are made of. These costs can add another $50 to the project. You also likely need a faucet installed with the new countertop and sink, adding $225 to $1,150 to the total cost, depending on the faucet and configuration. If the countertop is made to order for the vanity, this is done separately from the sink installation. Once the countertop is in place, the plumber can begin the sink and faucet installation but may need to return to finish it if the sink is installed below the countertop.​

Cost to Move a Bathroom Sink

The cost to move bathroom sink plumbing ranges from $500 to $1,000 to move the sink more than 3’. This does not include the cost of a new sink, faucet, or other materials but is only the cost of moving an existing fixture or its plumbing. It is common to move sinks during a bathroom remodel. Sometimes, you may find it helpful to move fixtures for a better layout during a remodel. Other times, you may be installing a double vanity and need to move existing lines a few feet to make room for the new lines. Many plumbing lines are flexible, so if you move the sink under 3’, your costs can be considerably less and equal to the cost of hooking up the new sink or faucet.

Enhancement and Improvement Costs

Sink Legs

If you like the idea of an open console sink but cannot find a style you want, you can use sink legs. These are a set of metal legs that can be used with a large pedestal top only or with a countertop and basin. They install at the front of the basin or countertop, while the back attaches to the wall. They cost $900 to $2,000 and come in many styles and finishes.

Additional Considerations and Costs

• Permits. Permits are not required for a sink installation. However, a permit may be required if you change the room’s layout, move the sink, or add plumbing. Speak to your local municipality for more information.
• DIY. You can install a new sink DIY if the rough plumbing is already in place. Drop-in sinks are the easiest. They hang from their rim with a small amount of adhesive, and the P-trap and drain hold them in place. Pedestal, wall-hung, and console sinks require bracing against the wall. Undermount sinks need at least 24 hours for the epoxy to cure before installing the drain.
• Hiring. When hiring a plumber to install your sink, get at least three references and ensure they are licensed and insured in your state.
• Reglazing. If you have a porcelain sink that is stained or has many cracks in the glaze, you can consider reglazing or refinishing the sink. Sink reglazing costs $50 to $100 per sink and can help restore the finish.
