If your bathroom stays damp, foggy, or musty no matter how often you run the fan, the right plants can make a noticeable difference. Over the years, I’ve tested dozens of houseplants in real bathrooms small windowless ones, bright spa-like ones, and everything in between. Some plants genuinely help regulate humidity, absorb excess moisture through their leaves, and tolerate low light better than others.
Below is a practical, experience-based guide to the best bathroom plants that absorb moisture, how to keep them healthy, and which ones actually thrive in the warm, humid microclimate of a bathroom.
Why Some Plants Absorb Moisture Better Than Others
Plants that thrive in bathrooms usually share a few characteristics:
- They naturally grow in tropical, humid forests
- Their leaves absorb moisture from the air
- They enjoy low to medium light
- They tolerate irregular airflow
In real home conditions, these plants noticeably reduce fog on mirrors and help prevent that “stale damp” smell.
Best Bathroom Plants That Absorb Moisture
These are the plants I’ve consistently seen perform best in humid bathrooms.
1. Boston Fern
One of the most efficient natural humidity absorbers.
Why it works:
- Large fronds pull moisture directly from the air
- Thrives in constant humidity
- Handles low to medium light
Tips:
- Keep soil slightly moist not soggy
- Give it a quick shower rinse every few weeks to remove dust
2. Spider Plant
A nearly indestructible option for humid bathrooms.
Benefits:
- Absorbs moisture through leaves and roots
- Handles low light surprisingly well
- Excellent air purifier
Great for small bathrooms because it stays compact and tolerates neglect.
3. Peace Lily
A top performer in both humidity absorption and air purification.
Why it thrives in bathrooms:
- Loves warm, moist environments
- Leaves naturally pull moisture from steam
- Tolerates low light better than most flowering plants
Note: Keep away from pets it’s toxic if eaten.
4. Pothos (Golden, Marble Queen, or Jade)
One of the most foolproof plants for steamy bathrooms.
Strengths:
- Absorbs moisture and pollutants
- Grows in low light, medium light, or even artificial light
- Vining habit fits shelves, hanging baskets, or top of cabinets
I’ve had pothos grow 10+ feet even in a tiny bathroom with no window and just LED lights.
5. Philodendron (Heartleaf or Brasil)
Another humidity-loving, low-light champ.
Why it works:
- Thrives in warm, damp air
- Absorbs moisture through broad, waxy leaves
- Very low maintenance
Perfect for placing near a shower where humidity spikes regularly.
6. Snake Plant (Sansevieria)
Not the strongest moisture absorber—but incredibly durable.
Good for:
- Dark bathrooms
- People who forget to water
- Tight corners
It tolerates humidity well but doesn’t rely on it great if your bathroom conditions fluctuate.
7. ZZ Plant
Ideal for bathrooms with very low light.
Benefits:
- Survives low humidity but loves high humidity
- Thick leaves absorb ambient moisture
- Requires watering only every few weeks
Perfect for windowless bathrooms.
8. Orchid (Phalaenopsis)
A surprising but excellent bathroom plant.
Why it works:
- Naturally grows in humid jungles
- Absorbs moisture through aerial roots
- Warm bathroom air improves blooming
If your bathroom gets bright, filtered light, orchids thrive beautifully.
9. Aloe Vera
Great for bright bathrooms.
Why:
- Clears humidity pockets near windows
- Stores moisture in its thick leaves
- Prefers indirect sun and light humidity
Avoid placing it directly in the shower zone it prefers to dry out between waterings.
10. Bamboo (Lucky Bamboo or Potted Bamboo Palm)
Very tolerant of humidity and low light.
Benefits:
- Pulls moisture from the air and soil
- Gives a spa-like look
- Easy to maintain
Lucky bamboo can even grow in water a great option for very steamy showers.
What You’ll Need to Keep Bathroom Plants Healthy
- Pots with drainage (humans love humidity; roots typically don’t)
- A tray or saucer to catch excess water
- Occasional airflow (open door for 10–20 minutes after showers)
- A microfiber cloth to wipe moisture off leaves occasionally
- Low-strength fertilizer every 1–2 months
Optional: A small bathroom grow light if the room is completely windowless.
Placement Tips (Based on Real Bathroom Conditions)
For dark bathrooms
- ZZ Plant
- Snake Plant
- Pothos

For bright, steamy bathrooms
- Boston Fern
- Peace Lily
- Orchid
- Bamboo Palm
For shelves and high spots
- Spider Plant
- Pothos
- Philodendron
For small countertops
- Aloe Vera
- Peace Lily (small pot)
- Lucky Bamboo
Expert Tips & Best Practices
- Let plants “enjoy” the steam place them where the warm humidity reaches them but not where water puddles.
- Rotate plants every few weeks to keep growth even.
- Avoid placing pots directly next to heat vents; it dries them out.
- Don’t overwater humid rooms often trick beginners into watering too much.
- Wipe bathroom walls regularly. More plants = more air purification, but moisture still needs ventilation.
FAQ
1. Do bathroom plants really absorb moisture? Yes plants with large, thin, or waxy leaves absorb water vapor. Ferns, peace lilies, and pothos are especially effective.
2. Can plants survive in a windowless bathroom? Yes. Pothos, ZZ plant, heartleaf philodendron, and snake plant survive well with artificial light.
3. How often should I water bathroom plants? Less than you think. Usually every 1–3 weeks depending on the plant and light level.
4. Why is mold growing on my bathroom soil? Poor airflow. Scrape it off, let the soil dry slightly, and open the bathroom door after showers.
5. Which bathroom plants clean the air? Peace lily, snake plant, spider plant, and pothos are all effective natural air purifiers.
When NOT to Use Plants for Moisture Control
Avoid bathroom plants if:
- The bathroom has zero ventilation (plants help humidity but can’t fix trapped mold)
- The space receives no light at all (use a grow light instead)
- You’re unable to monitor plant moisture (overwatering causes root rot fast in bathrooms)
Plants support humidity control they don’t replace ventilation.
Alternative Ways to Reduce Bathroom Humidity
- Run the exhaust fan for 15–20 minutes after showers
- Open the door or window
- Use moisture-absorbing trays with charcoal or clay beads
- Install a small dehumidifier if condensation is severe
Plants pair well with these solutions they work best together.
Conclusion: The Best Bathroom Plants That Absorb Moisture
The best bathroom plants that absorb moisture are Boston ferns, pothos, peace lilies, spider plants, and philodendrons. These species thrive in warm, humid environments and naturally help regulate the air while adding a lush, fresh look to the space. Choose plants based on your bathroom’s light level, water lightly, and give them occasional airflow, and they’ll do most of the humidity-control work for you.
