Color is secondary to finish in bathrooms. Use a bathroom-specific paint like Benjamin Moore Aura Bath & Spa or Sherwin-Williams Emerald with anti-microbial protection — they resist mildew and survive daily moisture.
Calming, spa-like choices: Benjamin Moore Quiet Moments (1563), Palladian Blue (HC-144), Healing Aloe (1562), or Pale Oak (OC-20).
Powder rooms are the best place in any Ottawa home to take a risk — deep emerald, navy, oxblood or even a wallpaper-look color all work because the room is small and rarely lived in for long periods.
