Specialized Bathroom Painting Service: Built to Handle Humidity & Steam

A standard full bathroom runs $250 to $600. Master bathrooms with more square footage or surfaces requiring mold treatment fall between $600 and $900. Half baths are typically $150 to $350. The variables that push cost up are surface condition – specifically mold or mildew requiring chemical treatment before primer – and damaged drywall near water sources that needs repair before anything goes on. We price all of it line by line after seeing the space.

A 100% acrylic satin or semi-gloss rated for high-humidity environments on walls. Satin minimum – flat and eggshell absorb moisture in a steam environment and fail early. For the ceiling above the shower, a moisture-resistant ceiling paint in a satin finish, not standard ceiling flat. For trim and vanity surfaces, a waterborne alkyd semi-gloss – harder cure and better moisture resistance than standard latex. The specific product matters less than the correct sheen and humidity rating for the location.

No. Painting over mold – with any product, including mold-resistant paint – doesn’t kill it. It grows through the new paint film, usually within a few months. The correct sequence is chemical treatment of the mold first, full dry time, then moisture-inhibiting primer, then topcoat. If the mold has penetrated the drywall itself, the affected section needs to be cut out and replaced before any painting work begins. We assess the extent of the problem on-site and tell you what the surface actually needs.

A standard full bathroom is typically one full day – morning for prep, mildew treatment if needed, and priming; afternoon for topcoats once the primer has flashed. If mold treatment requires a 24-hour dry time before priming, the job runs across two days. We don’t compress dry time in a bathroom – the humidity environment means adhesion failures from rushing show up faster here than anywhere else.

Satin is the practical answer for most bathroom walls. It sheds moisture better than eggshell or flat, cleans without scuffing, and doesn’t look as clinical as semi-gloss on a large wall surface. Semi-gloss on trim, vanity cabinets, and door casings – surfaces that get direct contact and need the hardest possible cure. Flat or eggshell in a bathroom is the wrong specification regardless of what the paint can says about scrub resistance.

Yes. Standard ceiling flat in a direct-steam environment is a failure waiting to happen. It absorbs moisture, softens, loses adhesion, and peels – usually in sheets, usually within a year or two. The ceiling above a shower needs a moisture-resistant primer and a humidity-rated ceiling paint in at least a satin finish. It costs slightly more than standard ceiling paint. The alternative is repainting it every two years.

Run the exhaust fan during every shower and for 15 to 20 minutes afterward. That single habit has more impact on paint longevity in a bathroom than any product upgrade. Beyond that: don’t use abrasive cleaners on painted surfaces, recaulk the tub and tile surround when the caulk starts showing cracks, and address any small peeling areas before they spread. A small touch-up done correctly lasts years. The same area painted over without fixing the underlying adhesion failure lasts months.
