Installing a bathroom vanity takes most professionals 3 to 6 hours. In Texas, labor alone usually runs $200 to $1,000, and the vanity itself adds anywhere from $100 for a basic premade unit to well over $12,000 for fully custom work. The job has seven stages: shut off the water, remove the old vanity, mark the studs, prep the new cabinet, level and secure it, set the sink and faucet, then reconnect and leak-test the plumbing.
What Is a Bathroom Vanity?
A bathroom vanity is a cabinet that holds your sink and gives you a countertop and storage in one piece. It started as a simple way to hide the plumbing. Today it is usually the centerpiece of the room, combining drawers, shelves, a basin and a finish that sets the tone for the whole bathroom.
Types of Bathroom Vanities
Picking the right style first makes every later decision, from cost to installation method, easier.
| Type | Best for | Installation note |
|---|---|---|
| Freestanding | Almost any bathroom; widest range of sizes and styles | Sits on the floor; the simplest to install |
| Wall-mounted (floating) | Modern or small bathrooms; makes the floor look larger | Needs solid wall support for the weight |
| Double-sink | Shared or master bathrooms | Two sets of plumbing connections; more labor |
| Custom | Odd layouts or one-of-a-kind designs | Highest cost and longest timeline |
How Much Does Bathroom Vanity Installation Cost?
In Texas, Florida, professional labor for a vanity installation typically falls between $200 and $1,000. Here is how the rest of the budget breaks down:
- Plumbing labor: $45 to $200 per hour, higher for complex work.
- Old vanity disposal: $115 to $500.
- The vanity unit: $100 to $2,600 for premade models; custom units can pass $12,000.
- Typical job length: 3 to 6 hours, longer if problems come up.
Prices vary by neighborhood and by contractor, so get at least two or three quotes before you commit.
What Affects the Total Cost?
Vanity type and style
Store-bought units are quicker and cheaper to install than custom ones. Wall-mounted and double-sink models cost more because they need precise measurements and extra plumbing connections.
Plumbing and electrical changes
Moving supply lines, drains or wiring is delicate work and should go to a licensed professional. It is also one of the fastest ways for a simple swap to get expensive.
Vanity size
Bigger vanities need more labor and sturdier materials. As a rule of thumb:
- 24 inches: powder rooms and tight spaces.
- 30 inches: small bathrooms.
- 36 inches: a popular all-rounder for standard bathrooms.
- 48 inches: medium bathrooms where you want storage without crowding.
- 60 to 72 inches: large, shared or master bathrooms.
Countertop material
Heavy or brittle materials need more careful cutting, setting and sealing, which adds hours to the job.
Location
Local demand and cost of living change labor rates, sometimes even between neighboring towns.
Removing the old vanity
Stone tops and heavy cabinets are harder to take out and haul away, and that effort shows up on the invoice.
Extras that add up
| Add-on | Typical cost |
|---|---|
| Backsplash | $1.50 to $30 per sq. ft. (ceramic and porcelain are cheaper than glass, marble or mosaic) |
| Flooring and trim fixes | $500 to $1,000 when the footprint changes |
| New sink | $40 to $300, with up to $400 for installation |
| New faucet | $70 to $900 |
| Partial wall removal (rare, for oversized vanities) | $300 to $1,000 |
Tools and Materials You Will Need
Adjustable wrench, pliers, utility knife, drill and driver, stud finder, level, tapered shims, hole saw, bucket, plumber’s putty, plumber’s tape, silicone caulk, construction adhesive and wall anchors for any screw that misses a stud.
How to Install a Bathroom Vanity: Step by Step
1-Shut off the water and disconnect the sink
Close the shutoff valves under the sink. Open the faucet to relieve pressure and let it run until it slows to a drip. Disconnect the supply lines with a wrench, then loosen the P-trap with pliers and detach it from the drainpipe. Keep a bucket handy, because some water will come out.
2-Remove the old vanity top and base
Cut through the caulk along the backsplash with a utility knife. If the top is held with screws or glue, work it free with a drill and chisel, then lift it off. Unscrew the base from the wall and pull it out. Patch any wall damage before moving on.
3-Mark the wall for the new vanity
Check the manufacturer’s instructions for height, width and placement, then outline the vanity on the wall. Use a stud finder to mark the studs inside that outline. Studs are usually 16 to 24 inches apart, and those are your anchor points.
4-Prep the back of the new vanity
Most vanities come with a plumbing opening, but if yours does not, measure from the base to the pipes using your wall outline and transfer those marks to the cabinet back. Cut holes for the drain and supply lines with a hole saw.
5-Position, level and secure the base
Slide the vanity into place along your outline. Check that it is level across all four corners and correct low spots with tapered shims. Drive screws through the back of the cabinet into the studs. Where a hole misses a stud, use wall anchors rated for your wall type.
6-Install the faucet, drain and sink
Put the plastic gasket under the faucet, feed the faucet and handles through their holes and tighten the washers and nuts underneath. Press a ring of plumber’s putty under the drain lip, seat the drain, tighten the mounting bracket and wipe away the excess putty. If the sink is separate from the countertop, set it now and follow the manufacturer’s instructions for your sink type.
7-Secure the vanity top
Run a thin bead of adhesive along the top of the base and lower the top into place, lining it up with the plumbing. Press down evenly so any overhang is the same on every side. Add silicone caulk behind and under a separate backsplash, or between the wall and the top if there is no backsplash. Let the caulk cure for at least 24 hours.
8-Reconnect the plumbing and test for leaks
Reattach the drain and supply lines, wrapping plumber’s tape around threaded fittings for a watertight seal. Turn the water on, run it for a few minutes and check every joint for drips. Tighten as needed, then attach doors, drawers and hardware.
How to Choose the Right Vanity
- Size: Measure the space first and leave room to move. In a small bathroom, compact or floating designs keep things open.
- Style and material: Oak and walnut bring warmth, while marble and quartz feel more upscale. Match the finish to your existing fixtures and tile.
- Storage: If space is tight, choose a unit with built-in drawers and shelves so the countertop stays clear.
- Plumbing fit: Check that the new unit lines up with your existing supply and drain locations. For a floating vanity, confirm the wall can carry the weight.
DIY or Hire a Professional?
A basic freestanding vanity swap is a realistic weekend project for a confident DIYer. Call a professional if you are:
- relocating plumbing or electrical lines,
- installing a wall-mounted or double-sink vanity,
- working with stone countertops or heavy units,
- dealing with water damage behind the old vanity.
A small mistake with a supply line or drain can cause hidden leaks, and repairs often cost more than the installation would have.
