Plants for a bathroom

Choose bathroom plants by light first, humidity second. A bright bathroom with a window is perfect for ferns, calatheas and orchids. A dim one suits pothos, cast iron plants and ZZ plants. A bathroom with no window can’t keep any plant alive long-term without a grow bulb.

Bathrooms are humid during and after showers, warm, and often small — great for many tropicals, as long as there’s light.

Pick by your bathroom

Your bathroom	Light test result	Best plants
Big window, bright	Soft or sharp shadow	Boston fern, calathea, moth orchid, bird’s nest fern, spider plant
Small or frosted window	Faint to soft shadow	Pothos, heartleaf philodendron, peace lily, parlor palm
Window in another room / skylight only	Faint blur	Cast iron plant, ZZ plant, snake plant
No window	No shadow	Any of the above with a grow bulb, or rotate plants weekly

Where to put them

• Windowsill: small ferns, orchids, spider plants.
• Top of the toilet tank or a shelf: trailing pothos or philodendron.
• Hanging from a shower curtain rod or ceiling hook: Boston fern or spider plant — out of the way and close to the steam.
• Corner floor spot: cast iron plant or parlor palm.
• Inside the shower: only if there’s a window in the shower; keep plants out of the direct spray and away from soaps.

Pet-safe bathroom picks

If a cat or dog uses the bathroom too, these are non-toxic according to the ASPCA: Boston fern, bird’s nest fern, calathea, spider plant, parlor palm, cast iron plant and moth orchid. Pothos, philodendron, peace lily, ZZ plant and snake plant are toxic — keep them high. More pet-safe plants →

Bathroom plant care tips

1. Water less than you think. Humid air slows evaporation, so soil stays wet longer. Check before watering.
2. Watch the cold. Bathrooms with exterior walls can get chilly at night in winter. Most tropicals want to stay above 55–60°F.
3. Clean the leaves. Hairspray, dust and soap residue block light; wipe leaves with a damp cloth monthly.
4. Give them a break. If the light is borderline, swap plants with a brighter room every couple of weeks.
5. Watch for mold on the soil surface. It means the soil stays too wet — water less and improve airflow.

The no-window bathroom setup

A full-spectrum LED bulb in the bathroom light fixture works if you leave it on 10–12 hours a day — use a smart bulb or a plug-in grow light with a timer instead of leaving the main light on. Keep plants within about 1–2 feet of the bulb. Low-light plants like ZZ, pothos and cast iron plant do best this way.
