Bathroom vanities age in a specific way. The finish chips around the edges first, then the drawer faces start to look scratched and tired, and eventually someone gets a replacement quote and stares at it in disbelief. Most vanities do not need to be replaced. Knowing how to refinish a bathroom vanity correctly transforms the same cabinet for under sixty dollars and a weekend of work. The key is understanding that prep work determines the outcome more than anything else. A coat of paint over a poorly prepared surface peels within six months. The same paint over a properly prepared surface lasts years.
You will need a liquid deglosser or 120-grit sandpaper for surface prep, a primer specifically designed for cabinetry or hard surfaces, a trim brush for the detail work around the edges, and a small foam roller for the flat door and drawer faces. A bonding primer is required if your vanity is laminate rather than solid wood, since regular primer does not adhere to laminate well. Chalk paint has become popular for this project because it requires minimal prep and skips the priming step on most wood surfaces. The tradeoff is that it needs a sealing coat of wax or polyurethane or it scratches easily in bathroom conditions.
Remove the cabinet doors and all hardware: knobs, pulls, and hinges. Label which hinges came from which door if they are not identical. The HOTO screwdriver set (see it here) has the right bits for cabinet hardware without stripping the heads. Wipe down all surfaces with a degreaser. Bathroom cabinets accumulate a film of skin oils, hair product, and general grime that prevents paint from bonding. Sand every surface with 120-grit sandpaper working with the grain. You are roughening the surface enough for the new paint to grip, not removing the finish entirely. Wipe away all the dust with a tack cloth before doing anything else.
Always prime before painting. Even if you use a primer-and-paint combination product, a separate dedicated primer coat makes a significant difference in adhesion and color uniformity. Apply primer to the inside of the cabinet first, then the outside, then the doors. Use thin coats and let each dry fully before the next. Rushing this step is the single most common mistake. Two thin coats adhere better than one thick coat and dry faster in total.
When you reach the color coat, maintain the same order: inside then outside then doors. A foam roller gives you a smoother finish on flat faces than a brush. Use the brush only for edges, details, and inside corners. If you see brush marks, they typically smooth out as the paint levels, but lightly sanding between coats with 220-grit produces a perfectly smooth finish.
In a bathroom, the top coat matters as much as the paint. A water-based polyurethane in a satin finish adds durability without the yellowing that oil-based versions develop over time. Apply two coats minimum, three if the vanity sees heavy use. Let the final coat cure for a full 24 to 48 hours before remounting hardware and reinstalling doors.
If you are doing broader bathroom work, the guide on installing a bathroom exhaust fan is worth reading alongside this project since a refinished vanity in a bathroom without proper ventilation will peel faster than one with good airflow. Exterior projects like cleaning your gutters or adding a deadbolt lock can fill the drying time between coats while you wait. Budget-conscious homeowners doing multiple projects in one season will find the Family Budget Reset useful for sequencing improvements without putting everything on a credit card. Refinishing a bathroom vanity takes patience in the prep stage and discipline in the drying stage. Get both of those right and you end up with a cabinet that looks like a replacement but cost you an afternoon. Our guide on paint kitchen cabinets is worth a read alongside this one.
