Bathrooms are naturally high-humidity spaces due to showers, poor ventilation, and frequent temperature changes. Excess moisture encourages mold growth, mildew buildup, and unpleasant odors that damage walls and fixtures.

Indoor plants that absorb moisture help regulate humidity naturally while improving air quality. According to indoor air studies, certain houseplants can reduce ambient moisture levels by up to 20–30% through transpiration.

These plants thrive in low light and high humidity, making them ideal for bathrooms. Many also filter airborne toxins and reduce condensation on surfaces.

In this guide, we cover the 20 best plants that absorb moisture in bathrooms, selected for humidity control, low maintenance, and visual appeal.
