The short answer
Stop the Water and Dry the Vanity
The first step is to stop the water source. Turn off the shutoff valve for the sink or the main water supply if a pipe has burst. Wipe up standing water with towels and use a wet-dry vacuum to pull moisture from drawers and crevices. Open cabinet doors and remove drawers so air can circulate around all surfaces.
Set up fans and a dehumidifier to speed up drying. In a humid climate like Rockwall, moisture can linger, so keep the area dry for several days. If the vanity sits on a wet floor, address that as well. Remove wet items from underneath and dry the floor with towels or a mop.

- Use a wet-dry vacuum to extract water from crevices
- Open doors and remove drawers for airflow
- Run fans and a dehumidifier for several days
- Mop up any water on the floor around the vanity
Assess the Damage Level
Check the vanity for swelling, warping, and delamination. Press on the surfaces to feel for soft spots. Look at the cabinet edges, drawer fronts, and the area around the sink. If the vanity is made of particleboard or MDF, water can cause it to swell and crumble, which often means replacement is needed.
Solid wood vanities may survive with sanding and refinishing, but plywood can separate. Check the sink base and the countertop for water stains. If the damage is only on the surface, you can repair it. If the structure is compromised, you will need to replace the affected parts or the entire unit.

- Look for swelling and warping at edges
- Check drawer fronts and cabinet sides
- Inspect the area around the sink base
- Test whether the material crumbles under pressure
Dry Out the Cabinet Interior
Once you have removed all visible water, focus on the inside of the cabinet. Pull out drawers and shelves. Use a hair dryer on a low setting to blow air into corners and joints. If you have a dehumidifier, place it near the vanity and run it for a day or two. This helps prevent mold from growing in the damp wood.
Check the floor of the cabinet for water damage. If the floor is soft or stained, you may need to replace it. For minor dampness, wipe it dry and let it air out. Keep the area well ventilated until everything feels completely dry to the touch.
Repair or Replace the Vanity
For minor damage, sand the affected areas to remove surface stains and rough spots. Fill small gouges with wood filler, let it dry, then sand smooth again. Apply a wood primer and paint or stain to match the rest of the vanity. If the vanity has a laminate finish, you may need to replace the laminate or the entire door.
If the damage is severe, such as a swollen particleboard base or a cracked sink, replacement is often more practical. You can buy a new vanity at a home improvement store. If you are not comfortable doing the work yourself, hire a local contractor or a water damage professional to handle the removal and installation.
When to Call in the Pros
If the water damage is extensive, or if you suspect mold growth, it is wise to bring in local water damage pros. They have the equipment to dry out walls, floors, and cabinets thoroughly. They can also identify hidden damage in the subfloor or behind the vanity that you might miss.
If the vanity is part of a larger water event, such as a pipe burst or a flood, you may need a full water extraction and drying service. In that case, check with your insurance company about coverage. Policies vary, and your insurer decides what is covered. They can guide you on next steps.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Can I fix a swollen vanity myself?
Yes, if the swelling is minor and the material is not crumbling. Sand the swollen area, apply wood filler, and repaint. If the particleboard is soft and disintegrating, replacement is the better option.
How long does it take for a vanity to dry out?
Drying can take two to five days, depending on humidity and airflow. Use fans and a dehumidifier to speed the process. In humid weather, it may take longer. Make sure everything is dry before repairing or refinishing.
Should I replace the whole vanity or just the damaged part?
If only a drawer or door is damaged, replace that piece. If the cabinet base or countertop is warped or swollen, the entire vanity may need replacing. Check the cost of parts versus a new unit before deciding.
