I’ve spent more hours than I’d like to admit scraping moldy soil out of expensive ceramic pots because I thought “low light” meant “no light.” It doesn’t. My first attempt at a “spa-like” bathroom ended with a shriveled Fern that looked like it had been through a dehydrator and a Snake Plant that literally turned into mush because of the steam.
If your bathroom is a dark, windowless cave that stays humid for three hours after you shower, you’re actually in a great spot—if you pick the right survivors. Most people buy whatever looks cute at the big-box store and wonder why it dies in three weeks. I’m here to tell you that 90% of what you see on Pinterest is a lie, but these 11 plants actually have the grit to thrive in your windowless humidity chamber.
1. The Indestructible Snake Plant (Sansevieria)
I once forgot a Snake Plant in my windowless basement guest bath for an entire summer. When I finally remembered it existed, it hadn’t just survived—it had put out a new pup. These things are basically the “cockroaches” of the plant world, and I mean that as the highest compliment. If you are the type of person who forgets to water until the soil looks like a cracked desert floor, this is your champion.
In a windowless bathroom, the Snake Plant is your best friend because it handles the high humidity without throwing a tantrum. While other plants might get root rot from the damp air, this guy just sits there looking stoic. It’s also one of the few plants that actually converts $CO_2$ into oxygen at night, which is a nice “science-y” bonus for your morning air quality.
When you’re searching for best low light plants for bathrooms, you’ll see this one everywhere for a reason. But here is my hard-earned secret: do not overwater it. In a windowless room, the water evaporates slower than a snail on a Sunday stroll. I only water mine about once every three or four weeks. If the soil feels even slightly damp, walk away. Put the watering can down.
I’ve found that the “Zeylanica” or “Black Coral” varieties handle the dim light of a bathroom lightbulb much better than the variegated yellow ones. The darker the leaf, the more chlorophyll it’s packing to soak up whatever pathetic light your vanity globe is putting out. It’s a tank. Buy it, forget it, and enjoy the green.
2. ZZ Plant: The “Zanzibar Gem” That Loves the Dark
If you want a plant that looks like it’s made of polished plastic but is actually alive, get a ZZ Plant. I call this the “set it and forget it” plant. Back in 2018, I had a ZZ plant in a bathroom with zero windows and a vent fan that sounded like a jet engine. The plant didn’t care. It stayed shiny and green while my shower steam did all the heavy lifting for its hydration needs.
The ZZ plant grows from these potato-like things under the soil called rhizomes. These are basically built-in water tanks. This means even if your bathroom gets humid, the plant isn’t thirsty. In fact, if you water it too much in a dark room, those “potatoes” will turn into a smelly, brown mess. I’ve made that mistake so you don’t have to—keep the soil dry.
People often search for low maintenance bathroom decor, and the ZZ plant fits the bill perfectly. It doesn’t drop leaves, it doesn’t attract many pests, and it grows slowly. Slow growth is actually a blessing in a small bathroom; you don’t want a jungle taking over your medicine cabinet while you’re trying to shave.
My neighbor once asked if mine was fake because it looked too perfect. I had to show her the dirt to prove it. For a windowless space, this is a top-tier choice because it can survive on the ambient light from the hallway or the few hours your bathroom light is on while you’re getting ready. It’s the ultimate “black thumb” insurance policy.
3. Peace Lily: The Drama Queen of Humidity
Let’s be real: the Peace Lily is a total drama queen. If it’s thirsty, it will literally collapse over the side of the pot like it’s auditioning for a Victorian soap opera. But here’s why it’s on my list for your windowless bathroom: it absolutely loves the steam. While most plants struggle with the “wet-dry-wet” cycle of a bathroom, the Peace Lily thrives in that tropical swamp vibe.
Because you don’t have a window, you’ll need to be careful with the light. I’ve found that Peace Lilies are one of the few flowering plants that won’t immediately kick the bucket in low light. They might not flower as much—or at all—without a window, but the deep green, glossy leaves are still beautiful. They act like a natural humidifier and air purifier all in one.
When looking for plants that absorb moisture in bathroom, the Peace Lily is usually the star of the show. It “drinks” through its leaves to some extent, making it perfect for that post-shower fog. Just a heads up: if you have a cat that likes to chew on things, skip this one. It’s toxic to pets, and nobody wants an emergency vet bill on a Tuesday night.
I keep mine on the floor next to the tub. The extra humidity from the bath water keeps the leaf tips from turning brown and crispy. If it does “faint” on you, just give it a splash of water and it’ll be standing upright again in two hours. It’s remarkably forgiving for a plant that acts so sensitive.
4. Spider Plants: The Retro Bathroom Staple
I remember my grandma having a Spider Plant in her windowless “powder room” that looked like an exploding green firework. These things are classic for a reason. They produce “pups”—tiny baby plants that hang down on long stems—which look incredible if you hang the pot from the ceiling or put it on a high shelf.
In a dark bathroom, a Spider Plant might lose its white variegation and turn solid green, but it won’t die. It’s trying to maximize its surface area to catch whatever light is bouncing off your bathroom mirror. I’ve found that they are incredibly resilient to the fluctuating temperatures of a bathroom, from the freezing morning air to the 80-degree steam of a long shower.
Searching for hanging plants for windowless bathroom? This is your winner. They don’t mind being slightly root-bound, so you don’t have to worry about repotting them every five minutes. Plus, they are amazing at scrubbing formaldehyde out of the air—which is actually a thing in bathrooms thanks to all the cleaners and hairsprays we use.
The only “gotcha” with Spider Plants is the brown tips. This usually happens because of the fluoride in tap water. Since you’re already in the bathroom, just use filtered water or let your tap water sit out overnight before pouring it in. Or, honestly, just trim the brown tips off with scissors; I do it all the time and the plant doesn’t mind the “haircut” one bit.
5. Pothos: The Gateway Drug of Houseplants
If you can’t grow a Pothos, you might want to switch to plastic. I’m serious. I’ve grown Pothos in dark closets, humid laundry rooms, and yes, windowless bathrooms. The “Golden Pothos” is the most common, and it’s a beast. It will vine down your shower rod, crawl across your mirror, and basically make you feel like a master gardener with zero effort.
The reason Pothos is one of the best plants for bathroom with no windows is its adaptability. It can grow in soil, or you can literally just stick a cutting in a vase of water and it will live there for years. In a humid bathroom, the aerial roots (those little brown bumps on the stems) will actually grab moisture from the air to help the plant stay hydrated.
One time, I tried to “train” a Pothos to grow around my towel rack. It worked a little too well—within six months, I couldn’t get my towel off without tangled leaves everywhere. Lesson learned: keep the vines directed toward the walls or ceiling. It’s an aggressive grower even in low light, which is rare.
Don’t buy the “Marble Queen” or “Snow Queen” varieties for a dark bathroom. Those white parts of the leaves can’t process light. Go for the “Jade Pothos” (solid green) or the “Golden Pothos.” They have more green “engine room” space to keep the plant running when the only light is coming from a 60-watt bulb.
6. Lucky Bamboo: The Low-Light Water Warrior
Technically, this isn’t bamboo—it’s a Dracaena—but who cares about semantics when it’s this easy to keep alive? Lucky Bamboo is a staple for modern bathroom plant decor because it looks clean, architectural, and can grow in nothing but pebbles and water. In a windowless bathroom, this is a massive win because you don’t have to deal with messy soil.
I keep a trio of these in a glass cylinder on my vanity. Because they grow in water, the humidity of the bathroom doesn’t really affect their hydration, but they do enjoy the damp air. They are incredibly tolerant of low light levels. I’ve had mine in a guest bath that only gets used (and lit) for about 30 minutes a day, and it’s still going strong after three years.
The biggest mistake I see people make is using straight tap water. These guys are sensitive to chlorine. If your bathroom smells like a swimming pool after a shower, your Lucky Bamboo will let you know by turning yellow. Use distilled water or just leave a jug of water out on the counter for 24 hours before you top up their vase.
Also, don’t forget to wash the pebbles occasionally. Biofilm (that slimy stuff) can build up in the water, especially in a warm, humid bathroom. Every few months, I just dump the whole thing out, rinse the rocks in the sink, and put it back together. It takes five minutes and keeps the plant from smelling like a swamp.
7. Cast Iron Plant (Aspidistra Elatior)
They don’t call it the “Cast Iron Plant” because it’s delicate. This plant was a favorite in Victorian-era England because it could survive in dark, drafty houses filled with coal smoke. If it can survive a Dickensian winter, it can survive your windowless bathroom. It has these long, elegant dark green leaves that look like they belong in a high-end hotel lobby.
I’ve found that this is the best choice if you have a larger bathroom floor space to fill. It grows in a clump and doesn’t vine, so it stays neat. It’s the ultimate “low light” champion. In fact, if you put it in direct sun, the leaves will actually bleach and die. It prefers the shadows, which makes it perfect for your no-window bathroom greenery needs.
One thing I love about the Cast Iron Plant is that it’s incredibly tough against temperature swings. If you like your showers boiling hot but your bathroom stays chilly the rest of the day, this plant won’t care. It’s also non-toxic to pets, which is a big plus for those of us with curious dogs or cats.
The downside? It grows slowly. Like, “glacier moving uphill” slowly. Don’t expect it to double in size over the summer. But the upside is that it won’t outgrow its pot for years. It’s a permanent fixture that provides a deep, moody green vibe that looks great against white subway tile or dark paint.
8. Heartleaf Philodendron: The Pothos’ Sophisticated Cousin
People often confuse this with Pothos, but the Heartleaf Philodendron has a slightly more delicate, matte look to its leaves. It’s just as tough, though. I have one trailing off the top of my medicine cabinet, and it handles the “no window” life like a pro. The humidity keeps the leaves lush and prevents that dusty look that indoor plants sometimes get.
When you’re searching for climbing plants for bathrooms, this one should be at the top of your list. It’s very easy to propagate, too. If a vine gets too long, you just snip it off, stick it in water, and boom—you have a new plant for your kitchen. I’ve basically populated my entire house starting with one “mother” plant I bought at a garage sale for three dollars.
I’ve found that Philodendrons are a bit more expressive than Pothos. If it’s unhappy, the leaves will get smaller and smaller. If you notice your new leaves are the size of a dime, it’s telling you it needs a little more light. In a windowless bathroom, you can “cheat” by leaving the bathroom light on for a few extra hours or swapping your regular bulb for a full-spectrum LED bulb.
The “Heartleaf” is my go-to recommendation for anyone who wants that “jungle” look without the “jungle” work. It’s graceful, it’s resilient, and it loves the steam. Just make sure to wipe the leaves down with a damp cloth every once in a while; dust can block what little light the plant is trying to absorb.
9. Bird’s Nest Fern: The Humidity Lover
Now, I usually tell people to stay away from Ferns. Maidenhair Ferns, for example, are the devil’s work—they will die if you even look at them wrong. But the Bird’s Nest Fern is different. It has thick, wavy fronds that feel more like succulent leaves than typical fern fluff. This thickness helps it hold onto moisture and tolerate the lower light of a windowless room.
In the wild, these grow on trees in tropical jungles, so they are literally designed for high humidity and dappled shade. Your bathroom is basically its natural habitat. It loves the steam from your morning shower. I keep mine in a terracotta pot to help the roots breathe, but I sit that pot inside a decorative ceramic one to keep the moisture levels consistent.
If you’re looking for bathroom plants that like steam, this is a top contender. It adds a really cool, architectural texture that breaks up all the straight lines of your vanity and tile. Unlike other ferns, it doesn’t shed tiny little leaflets all over your floor, which is a huge win for keeping the bathroom clean.
Just a pro tip: water it around the edges, not into the center (the “nest”). If water sits in the middle of the plant, it can cause the crown to rot, especially in a room without a window to help it dry out. I learned that the hard way when my first one turned into a soggy brown mess in the middle of January.
10. Dragon Tree (Dracaena Marginata)
If you have a corner in your bathroom that feels empty and sad, the Dragon Tree is your solution. It has these thin, spiky leaves that grow on top of woody stems, giving it a bit of a “Dr. Seuss” look. While it prefers bright light, it is surprisingly tolerant of lower light conditions, especially if it’s a mature plant.
I’ve used these to add height to a bathroom without taking up much floor space. Because they grow vertically, they fit perfectly next to a pedestal sink or in that weird gap between the toilet and the wall. The humidity of the bathroom is actually great for them because it prevents the leaf tips from getting that “scorched” brown look that happens in dry living rooms.
When searching for tall plants for windowless bathrooms, the Dracaena is usually the best bet. It’s much hardier than a Fiddle Leaf Fig (which would die in a windowless room in about four days). It’s a slow grower, so you don’t have to worry about it hitting the ceiling anytime soon.
Warning: these are toxic to pets. Also, they hate being moved. Once you find a spot where it looks happy, leave it there. I once moved mine three feet to the left and it dropped half its leaves in protest. It eventually recovered, but it took its sweet time to forgive me.
11. Bonus Side Note: The “Air Plant” (Tillandsia)
I’m adding this as a bonus because it’s not a “potted” plant in the traditional sense. Air plants don’t need soil at all. They get all their nutrients and water through their leaves. In a windowless, humid bathroom, they are incredibly happy because they can literally “drink” the shower steam.
You can mount these on pieces of driftwood, put them in glass terrariums, or even just set them on a shelf. They are the ultimate space-saving bathroom plants. However, don’t be fooled—they still need some light. If your bathroom is pitch black 23 hours a day, these won’t make it. But if you leave the light on while you’re home, they’ll do just fine.
The trick with air plants in a bathroom is to make sure they dry out between “steams.” If they stay wet for too long without airflow, they will rot from the inside out. I give mine a “bath” (soaking them in a bowl of water) once every two weeks, then I make sure they are bone dry before putting them back in the bathroom.
They are cheap, weird-looking, and a great conversation starter. If you have zero counter space but want some green, grab a few air plants and stick them to your mirror with a little suction cup holder. It looks cool and keeps them out of the way of your toothbrush.
Real Talk: What Actually Happens in a Windowless Bathroom
I’m going to be honest with you: no plant loves a windowless room. Plants need light to eat. Keeping a plant in a room with no windows is like keeping a human on a diet of only crackers—you can survive, but you aren’t exactly “thriving.”
The Light Bulb Trick
If you want these plants to actually grow (and not just slowly die over two years), you need to change your light bulbs. Standard incandescent bulbs do nothing for plants. Swap your vanity lights for “daylight” balanced LED bulbs (look for 5000K-6500K on the box). They mimic the spectrum of the sun and will give your plants the “food” they need to stay green.
The “Rotating” Strategy
I’ve found that the best way to keep “windowless” plants looking great is the “Switcharoo.” I keep two sets of plants. One set stays in the bathroom for two weeks, while the other set sits by a sunny window in the living room. Every other Sunday, I swap them. This gives the bathroom plants a “recharge” in actual sunlight. It sounds like a lot of work, but it takes three minutes and saves you from buying new plants every six months.
The “Pinterest” Trap
Don’t buy Succulents or Cacti for your windowless bathroom. I don’t care how many “top 10” lists tell you they are easy. Succulents need high light and low humidity. Putting a Echeveria in a windowless, steamy bathroom is a death sentence. It will stretch out, turn pale, and eventually rot. Stick to the tropicals I listed above—they are built for the damp.
Parting Wisdom
Decorating a windowless bathroom with plants is totally doable, but you have to play by the rules of biology. Focus on “low light” tropicals, watch your watering like a hawk, and maybe invest in a better light bulb. My bathroom went from a sterile, white box to a little oasis just by adding a Pothos and a Snake Plant, and yours can too.
Just remember: if the plant dies, don’t beat yourself up. I’ve killed enough greenery to fill a small landfill. Every dead plant is just a lesson in what not to do next time.
