Bathroom paint calculator
Bathrooms are small but always need a moisture-tolerant finish. A typical 8 × 6 ft bathroom has ~225 sq ft of wall area, which works out to about a gallon for two coats. Use satin or semi-gloss — bathrooms get steam, splash, and require frequent wipe-downs.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
Recommended finish: satin
How much paint for a bathroom?
For a standard 8 × 6 ft bathroom: 1 gallon covers walls + ceiling for two coats. A primary/master bath at 10 × 8 ft pushes you to 1.5 gallons.
Why satin, not flat
Flat paint absorbs steam and shows water spots within months. Satin or eggshell with mildew-resistant additives is the rule. Kompozit PRO satin is washable and rated for moisture-prone areas.
FAQ
A standard premium interior paint in satin or semi-gloss works fine in most bathrooms — what you actually need is enough sheen to wipe clean and a film tight enough not to soak up moisture. Mildew-resistant additives help in poorly ventilated bathrooms.
Yes — bathroom ceilings get hit with steam and discolor faster than any other ceiling in the house. Use a flat or eggshell ceiling paint with mildew resistance, or just use the same satin/semi-gloss as the walls if you want a single-can job.
