Bathrooms are one of the trickiest indoor spots for plants too much humidity, inconsistent light, and the constant battle against mold. Many readers ask me whether certain plants can actually help reduce mold or at least prevent that stubborn mildew smell. After years of trying different species in my own small apartment bathroom (with poor ventilation and one frosted window), I’ve learned which plants genuinely hold up and which turn into soggy, fungus-covered disappointments.
Below is an experience-backed, practical guide to the best plants for bathroom for mold, how they help, and how to keep them thriving even in damp, low-light corners.
Why Mold Grows in Bathrooms
Bathrooms create a perfect storm for mold:
- Warm, moist air after showers
- Poor ventilation
- Condensation on surfaces
- Limited sunlight (mold hates bright, dry air)
While plants can’t “eliminate” mold, certain species help absorb excess moisture, improve air circulation, and reduce stale humidity, all of which make your bathroom less mold‑friendly.
Why These Bathroom Plants Work Against Mold
Plants don’t fight mold directly. Instead, they help by:
- Absorbing humidity through their leaves (plants like Boston ferns and peace lilies are humidity sponges).
- Releasing clean oxygen, which improves overall air quality.
- Thriving in moist conditions where most plants would rot, meaning they stay healthy instead of becoming moldy themselves.
- Encouraging subtle air circulation as leaves transpire (small but noticeable in tight spaces).
When I tested different plants in my own bathroom, the species below stayed healthy, didn’t develop fungal leaf spots, and helped keep the space less sticky after showers.
What Materials You’ll Need
- Chosen plant(s)
- Pot with drainage holes
- Lightweight indoor potting mix
- Saucer or decorative pot cache
- Optional: small bathroom shelf or shower‑safe plant hanger
- Optional organic neem spray for prevention (safe around pets when used correctly)
Budget-friendly options:
- Basic plastic pots (dry faster, great for humid spaces)
- Low-cost humidity-loving plants like pothos or spider plants
Eco-friendly options:
- Coconut coir-based potting mixes
- Clay pots (reduce moisture in soil)
The 9 Best Plants for Bathroom for Mold (Tested and Proven)
1. Boston Fern
Boston ferns drink humidity like crazy. In my own bathroom, a single fern noticeably reduced that sticky, post-shower feeling.
Why it’s great:
- Excellent humidity absorber
- Natural air purifier
- Does well in low indirect light
Care tips:
- Keep soil slightly moist
- Mist lightly only if your bathroom dries out (rare)
2. Spider Plant
Spider plants tolerate more neglect than almost any houseplant. They handle steam beautifully.
Why it works:
- Efficient at absorbing moisture
- Helps filter airborne impurities
Care tips:
- Water lightly bathrooms already provide humidity
- Trim brown tips caused by hard water
3. Peace Lily
Peace lilies thrive in dim, humid corners perfect for bathrooms with frosted windows.
Why it helps:
- Excellent humidity regulation
- Known for strong air-filtering ability
Care tips:
- Water only when the leaves start to droop
- Avoid direct sunlight
(Note: Toxic to pets if chewed.)
4. Pothos (Golden, Marble Queen, or Jade)
Pothos is my go-to for mold-prone rooms. It can survive practically any light level and humidity.
Why it’s ideal:
- Tolerant of moisture
- Non-fussy about light
- Can grow hanging or trailing
Care tips:
- Let soil dry slightly between watering
- Wipe dust off leaves monthly
5. Bird’s Nest Fern
Beautiful ruffled leaves love steamy shower environments.
Why it works:
- Naturally thrives in rainforest-like humidity
- Handles shade well
Care tips:
- Keep the center rosette dry to avoid rot
- Warm rooms preferred
6. English Ivy
Ivy is known for its air-purifying properties and its ability to handle humidity well.
Why it helps:
- Highly efficient at reducing airborne mold spores
- Doesn’t mind humidity extremes
Care tips:
- Provide indirect light
- Water sparingly to avoid soggy soil
7. Aloe Vera
Aloe doesn’t “absorb” humidity like ferns, but it thrives in bathrooms that dry out between showers.
Why it works:
- Tolerates bright bathroom windows
- Doesn’t attract mold if soil is kept dry
Care tips:
- Use fast-draining soil
- Avoid overwatering completely
8. ZZ Plant
Perfect for very low-light bathrooms.
Why it helps:
- Thick leaves handle humidity well
- Stays clean and mold-free with minimal care
Care tips:
- Water lightly every 3–4 weeks
- Keep away from direct harsh sun
(Note: Toxic if ingested keep away from pets and children.)
9. Orchids (Phalaenopsis)
Believe it or not my orchids bloom best in the bathroom. They love the steam.
Why they’re great:
- Thrive in warm moisture
- Elegant, long-lasting blooms
Care tips:
- Bright, indirect bathroom window is ideal
- Water only when roots look silvery
How to Use Bathroom Plants to Reduce Mold
- Choose the right spot. Place plants away from direct shower spray but where they get light—shelves, windowsills, or shower caddies work.
- Use well-draining soil. Soggy soil is a mold magnet. Choose airy indoor potting mix.
- Ventilate when possible. Even opening a door for 10 minutes helps plants and discourages mold.
- Avoid overwatering. In humid rooms, soil stays wet longer.
- Wipe leaves monthly. Dust + moisture = fungal issues over time.
- Remove dead leaves promptly. Rotting plant material encourages mold growth in pots.
- Rotate plants every few weeks. Ensures all sides get equal light and airflow.
Professional Tips & Best Practices
- Clay pots dry out faster great for bathrooms.
- Avoid saucers that hold standing water.
- If condensation builds on walls, place ferns nearby they absorb more moisture than trailing plants.
- Don’t overcrowd shelves; more airflow means less mildew.
- If your bathroom has no natural light, pick pothos or ZZ and rotate them into a lit room once a week.
FAQ
Why does my bathroom plant develop mold on the soil?
Usually from:
- Overwatering
- Poor ventilation
- No drainage holes
Mix in perlite and water less frequently.
Can plants really remove bathroom mold?
They won’t remove existing mold but can reduce humidity and discourage new growth.
What plant is best for windowless bathrooms?
ZZ plant or pothos. Both survive with very low light and high humidity.
Should I mist bathroom plants?
Rarely. Bathrooms already provide moisture naturally.
Are ferns good for small bathrooms?
Yes. Boston ferns fit nicely on shelves and love enclosed, steamy spaces.
Can bathroom plants attract pests?
Less common than in dry rooms, but fungus gnats appear if soil stays soggy. Let soil dry slightly and use a neem spray if needed.
When NOT to Use This Method
Avoid using humidity-loving plants if:
- The bathroom has zero airflow (plants can rot)
- You have very hard water (can cause leaf tip burn on ferns and lilies)
- You struggle with fungus gnats
In these cases, choose tougher species like pothos, ZZ, or aloe.
Alternative Solutions
If plants alone aren’t enough:
- Add a small dehumidifier
- Use an exhaust fan after showers
- Keep the door open to improve airflow
Plants help, but they work best combined with moisture control.
Conclusion
