Painting bathroom cabinets correctly hinges on full prep: remove doors, degrease, sand, prime, and apply thin coats with full cure time.
Most painted vanity failures trace back to skipped prep, not bad paint. When you paint bathroom cabinets correctly, the finish looks factory-smooth and survives years of steam, humidity, and daily splashes. The difference between a flaking mess and a durable result comes down to a handful of steps that take patience but no special skill.
Prepping the Vanity: Removal and Deep Cleaning
Start by emptying the vanity completely and removing every door, drawer, and false front. This isn’t optional busywork—painting assembled cabinets leaves visible hinge lines and missed spots. Label each piece with its location using painter’s tape so reassembly takes minutes instead of guesswork.
Lay drop cloths or rosin paper over floors and counters, and tape off walls and the sink area. Then tackle the grease. Sherwin-Williams directs washing surfaces with water and degreasing dish soap to remove soap scum, hairspray, and lotion residue, followed by a double rinse with fresh water and full drying. Benjamin Moore agrees, suggesting a damp cloth with degreaser and a fresh-water rinse.
Skip this step and the paint has nothing to grip. Residue acts as a release layer, and no primer can fix a greasy surface.
Sanding, Priming, and Painting the Surfaces
Once surfaces are bone-dry, sanding comes next. Benjamin Moore specifies medium-grit 150 sandpaper on finished cabinets first, then a light pass with fine-grit 220, always working with the wood grain. The goal is scuffing the gloss, not removing the wood. Wipe away all dust with a tack cloth afterward.
Priming is non-negotiable for adhesion. Benjamin Moore directs using STIX® Waterborne Bonding Primer on the frame and each door and drawer, letting it dry fully before any topcoat. Sherwin-Williams recommends testing primer adhesion in an inconspicuous spot first, then priming everything if the bond holds.
For the topcoat, Benjamin Moore uses ADVANCE® Interior Paint on vanity surfaces. High-quality cabinet paint in satin, semi-gloss, or high-gloss sheens gives the best durability and easiest cleaning. Apply with a brush for edges and details and a roller for flat panels, working lightly with the grain to avoid drips and brush marks. Thin coats win here.
Dry Time, Cure Time, and Reassembly Timing
Sherwin-Williams says to add two additional coats after priming, then leave the project overnight so the paint fully dries. Benjamin Moore directs a second coat only after the first is completely dry. Build in thin layers—one thick coat dries unevenly and sags.
Timing matters beyond dry-to-touch. Topcoat should dry at least 12 hours, with 24 hours before normal use. The vanity feels dry within an hour, but the finish isn’t fully cured for about seven days. Hardware installation and loading the vanity should wait until cure completes. Check your specific paint label since cure times vary by product.
Common mistakes that ruin results: reassembling too soon, skipping the degrease, painting over glossy surfaces unsanded, using thick drippy coats, and ignoring label instructions. Avoid those and the finish holds up like new for years.

| Step | What to Do | Why It Matters |
|---|---|---|
| Remove hardware | Take off doors, drawers, hinges, and knobs; label everything | Clean edges and even coverage with no missed spots |
| Degrease | Wash with degreasing dish soap, rinse twice, dry fully | Removes soap scum and oils that block adhesion |
| Sand | Use 150-grit then 220-grit, with the grain | Scuffs gloss so primer and paint can grip |
| Prime | Apply bonding primer and let dry completely | Creates a uniform base for durable topcoats |
| Paint | Apply 2+ thin coats, brush edges, roller flats | Thin layers dry evenly without drips or marks |
| Cure | Wait 12-24 hours dry, 7 days full cure | Prevents dents, scratches, and stuck hardware |
FAQs
Can I paint over previously painted bathroom cabinets?
Yes, as long as the existing paint is sound and not peeling. Clean thoroughly with degreaser, sand with 150-grit then 220-grit to scuff the gloss, and apply a bonding primer before the new topcoat. If the old finish is chipping or failing, strip it down to bare wood first.
What sheen should I use for bathroom cabinet paint?
Satin, semi-gloss, or high-gloss sheens work best for bathroom vanities. These finishes resist moisture, wipe clean easily, and hold up to humidity better than flat or eggshell paints. Semi-gloss is the most popular middle ground between durability and a soft sheen.
How long should I wait before putting the vanity back in use?
Wait at least 12 hours for the topcoat to dry, and 24 hours before normal daily use. The paint is dry to the touch within an hour, but the finish needs about seven days to fully cure. Hold off on reinstalling hardware and loading the vanity until then to avoid dents and scratches.
