How Much Does It Cost to Paint a Bathroom? (Moisture-Safe Paint Price Guide)
Bathrooms are small, so people assume they’re the cheapest room to paint. The room size is smaller, but the paint itself costs more — and skipping the right formula leads to peeling within a year.
Why bathroom paint costs more
Standard wall paint isn’t rated for constant humidity. Bathroom-specific paint (labeled “bath and spa” or “moisture-resistant”) has mold-inhibiting additives and a tighter finish that sheds condensation instead of absorbing it.
| Standard paint | Bathroom/moisture-resistant paint | |
|---|---|---|
| Price per gallon | $25–$40 | $40–$65 |
| Expected lifespan before peeling | 1–2 years in a bathroom | 4–6+ years |
Full cost breakdown
For an average bathroom (roughly 8 ft x 6 ft with 8 ft ceilings — small wall area, but more cutting-in around fixtures):
| Item | Cost range |
|---|---|
| Moisture-resistant paint (1–2 gallons) | $40–$110 |
| Primer (recommended over old standard paint) | $20–$35 |
| Painter’s tape (for tight edges around tile/fixtures) | $8–$15 |
| Brushes for detail work | $10–$20 |
| Total DIY cost | $78–$180 |
Hiring a professional
Because of the cutting-in work around toilets, vanities, and tile, painters often charge a similar flat rate to a bedroom despite the smaller size: $250–$500 for a standard bathroom.
Where people cut corners (and pay for it later)
Using leftover wall paint from another room is the single most common bathroom paint mistake. It looks fine for a few months, then starts bubbling near the shower and shows visible mold spotting behind the toilet within a year — both of which cost more in cleanup and repainting than the $15–$25 price difference would have.
Bottom line
Budget $80–$180 for a proper moisture-resistant bathroom paint job. It costs 30–50% more upfront than standard paint but avoids a repaint in half the time — the math favors doing it right the first time in a room with constant humidity.
