The best bathroom plant is a pothos: it drinks up the shower steam, trails beautifully from a shelf, and survives in low light. Bathrooms are the one room where humidity works for you, most tropical houseplants come from steamy jungles, so the moist air after every shower is exactly what they want. Below are 16 picks split by whether you have a window or not, each with its light needs, humidity fit, and pet-safety, so you buy one that thrives on your actual bathroom.
Key Takeaways
- Pothos is the best all-rounder for a bathroom: loves humidity, tolerates low light, roots in water, $8 to $18
- Humidity is the reason tropical plants thrive here, shower steam mimics their native jungle air
- No window? It’s still doable with ferns, ZZ plant, and pothos, plus a small grow light or a monthly rotation to a brighter room
- Pet owners: most classic bathroom plants (pothos, philodendron, snake plant) are toxic; choose Boston fern, spider plant, or parlor palm instead
- Match the plant to your window first, then pick a spot: shower shelf, over the toilet, hanging, or the vanity
Why Does Bathroom Humidity Help Plants?
Bathroom humidity helps because most popular houseplants are tropical, and they evolved in warm, moist forests where air stays 60 to 90% humid. The average heated home sits near 30% humidity, which is desert-dry for a fern. Every shower briefly pushes your bathroom back toward jungle levels, and that steam is free plant care.
We keep a small hygrometer on our bathroom shelf, and after a hot shower it climbs from around 45% to over 80% for an hour or so. Ferns, calatheas, and air plants that crisp up and brown in a normal living room stay soft and green in that same steamy corner. If your plant leaves keep getting brown, papery edges elsewhere in the house, the bathroom is often the fix.
Two things to remember. Humidity is a bonus, not a substitute for light or water, and good drainage still matters so roots never sit soggy. For a wider primer on forgiving plants, see our guide to the best low-maintenance indoor plants.
Best Bathroom Plants If You Have a Window
If your bathroom gets natural light, even a small frosted one, your options open way up. Bright indirect light plus humidity is close to ideal for tropicals. According to The Spruce, ferns and orchids are among the plants that most reward a humid, lit bathroom.
- Boston fern: medium indirect light · loves high humidity · pet-safe: yes. The classic steamy-bathroom fern. $15 to $30.
- Orchid (Phalaenopsis): bright indirect · high humidity · pet-safe: yes. Blooms for months in bathroom air. $18 to $35.
- Spider plant: medium light · likes humidity · pet-safe: yes. Makes babies, perfect for hanging. $10 to $20.
- Calathea (prayer plant): medium indirect · high humidity · pet-safe: yes. Notoriously fussy elsewhere, happy here. $15 to $28.
- Croton: bright indirect · likes humidity · pet-safe: no. Bold orange and red foliage. $18 to $30.
- Aloe vera: bright light · tolerates humidity · pet-safe: no. Handy for minor burns. $10 to $22.
- Air plant (Tillandsia): bright indirect · thrives on humidity · pet-safe: yes. No soil, mist or dunk weekly. $6 to $15.
Calathea is our own proof of concept here. We killed two in a dry hallway before moving a third onto a windowsill above the tub, and it’s held its color for over a year with almost no extra misting. For more trailing options, browse our hanging plant ideas for indoors.
Can Plants Live in a Windowless Bathroom?
Yes, plants can live in a windowless bathroom. Humidity is already covered, so the one thing to solve for is light. Plenty of bathrooms have little to no natural light, which is the most common bathroom-plant problem, and it’s fixable with two simple tactics (Apartment Therapy has good low-light guidance too).
The first tactic is a small LED grow light. A clip-on or bulb-style grow light ($15 to $40) on a timer for 8 to 12 hours a day replaces the sun for most low-light plants. We run a $25 clip light over a windowless powder room, set to a plug-in timer, and a pothos there has doubled in a year. The second tactic costs nothing: rotate. Keep two plants and swap them every couple of weeks, one recovers on a bright windowsill while the other decorates the bathroom.
What most guides miss: the electricity cost of a grow light is tiny. A typical 10-watt LED clip light running 12 hours a day pulls only about 44 kWh over a year, which at the US average residential rate lands near $7 a year, roughly the price of one new plant. The catch is the flip side: humidity cannot rescue a plant that genuinely needs light. In a truly dark, windowless bathroom, calathea, Boston fern, orchid, and croton tend to yellow, drop leaves, and rot at the roots. Save those for a window and keep pothos, ZZ, snake plant, and cast iron in the dark spots.
These plants handle a dim, windowless bathroom best, especially with a grow light or rotation:
- Pothos: very low light tolerant · loves humidity · pet-safe: no. The top windowless pick. $8 to $18.
- ZZ plant: very low light · tolerates humidity · pet-safe: no. Nearly unkillable, glossy leaves. $15 to $30.
- Snake plant: low light · handles humidity fine · pet-safe: no. Upright, architectural, forgives neglect. $10 to $25.
- Cast iron plant: low light · tolerates humidity · pet-safe: yes. Named for its toughness. $20 to $40.
- Peace lily: low to medium light · loves humidity · pet-safe: no. May still bloom under a grow light. $15 to $30.
- Philodendron (heartleaf): low to medium · loves humidity · pet-safe: no. Fast, easy trailer. $12 to $22.
- Parlor palm: low light · likes humidity · pet-safe: yes. Soft, safe, tolerant of dim corners. $15 to $30.
Windowless bathrooms and tight apartments overlap a lot, so our small apartment plants and low-light indoor plants guides go deeper on both.
Which Bathroom Plants Are Safe for Pets?
Only about half of the popular bathroom plants are pet-safe, so cat and dog owners need to choose carefully. The ASPCA lists pothos, philodendron, peace lily, snake plant, and ZZ plant as toxic to cats and dogs, which rules out several favorites. The good news: plenty of humidity-lovers are non-toxic.
Pet-safe bathroom plants (non-toxic per the ASPCA):
- Boston fern · Spider plant · Calathea · Parlor palm · Cast iron plant · Air plant · Orchid
What most guides miss: not all “toxic” plants are toxic the same way. Pothos, philodendron, and peace lily contain insoluble calcium oxalate crystals, so a chewed leaf triggers intense mouth burning, drooling, and vomiting rather than a fatal poisoning, per the ASPCA. It is rarely deadly but genuinely miserable for a curious cat. That is why we keep those three well out of reach, up on a high shelf or hanging, and build the counter-level and floor plants only from the non-toxic list above.
If pets roam your bathroom, build your setup from that list first. A Boston fern over the toilet plus a spider plant hanging by the window gives you lush greenery with nothing dangerous within reach.

Where Should You Put Plants in a Bathroom?
Put bathroom plants where they get steam without blocking daily use, the four best spots are a shower shelf, over the toilet, hanging, and the vanity. Position matters as much as the plant, a fern jammed behind the toilet lid where nobody sees it does nothing for the room.
Here’s how we assign each spot:
- Shower shelf or ledge: best for air plants and small pothos that soak up the most steam. Use suction or tension-rod shelves in rentals.
- Over the toilet: the classic empty wall. A floating shelf with a trailing pothos or a Boston fern fills it fast.
- Hanging from the ceiling or a hook: spider plants and pothos trail dramatically and stay out of the splash zone.
- Vanity or windowsill: small plants like calathea or an orchid at eye level, where you’ll actually enjoy them while getting ready.

Frequently Asked Questions
What plants do well in a bathroom?
Pothos, Boston fern, spider plant, snake plant, ZZ plant, and peace lily all do well in a bathroom because they tolerate low light and enjoy the humidity from showers. Pothos is the easiest all-rounder; Boston fern is the best pet-safe choice for a lush, tropical look.
Can plants live in a windowless bathroom?
Yes. Humidity is covered by your showers, so you only need to solve for light. Add a small LED grow light ($15 to $40) on a timer for 8 to 12 hours a day, or rotate two plants every couple of weeks so each recovers in a brighter room. Pothos, ZZ plant, and snake plant handle it best.
Are bathroom plants good for humidity?
Bathroom plants don’t add much humidity to a room, but they thrive on the humidity that’s already there. Tropical plants evolved in 60 to 90% humid forests, while a heated home sits near 30%. The shower steam that briefly pushes your bathroom toward jungle levels is exactly what keeps ferns and calatheas soft and green.
Which bathroom plants are safe for cats and dogs?
Boston fern, spider plant, calathea, parlor palm, cast iron plant, air plant, and orchid are all non-toxic per the ASPCA. Avoid pothos, philodendron, peace lily, snake plant, and ZZ plant, which are toxic to pets if chewed.
Do bathroom plants need to be watered less?
Usually yes, slightly. The higher humidity slows how fast soil dries out, so many bathroom plants need water a little less often than the same plant elsewhere. Always check the top inch of soil first; overwatering, not underwatering, kills most houseplants.
How much does it cost to run a grow light for bathroom plants?
Very little. A 10-watt LED clip grow light on 12 hours a day uses roughly 44 kWh a year, about $7 at the US average electricity rate. The light itself runs $15 to $40, so a full first-year setup for a windowless bathroom stays under $50.
