The Bathroom: A Surprisingly Good Place for Plants
Most people don't think of their bathroom as a plant habitat, but for quite a few species it's actually close to ideal. Bathrooms tend to be warm, humid from showers and baths, and in the UK they're often lit by a frosted window that gives soft, indirect light, exactly what many tropical plants prefer.
The main challenges are the temperature swings between a steamy shower and a cold morning, and the fact that many UK bathrooms don't have operable windows, which can limit air circulation. Light can also be an issue in smaller bathrooms or those with north-facing windows. But there are plants here that handle all of those conditions well.
The plants that do best in bathrooms generally come from humid, tropical environments, forest floors where light is filtered, moisture is constant, and temperatures are warm. Ferns are the obvious choice, but orchids, prayer plants, and even air plants do brilliantly in a bathroom with regular use.
One practical note: bathrooms are often tiled, which means cold floors in winter. Avoid putting pots directly on cold tiles if you can, a small stand or mat underneath helps keep root temperatures more stable. And make sure the light, however dim, is genuinely enough for the plant. A completely windowless bathroom needs a grow light to be viable for plants over the long term.
Our Top Bathroom Plant Picks
Boston Fern (Nephrolepis exaltata)
If there's one plant that belongs in a bathroom, it's the Boston fern. It craves exactly what a bathroom provides: indirect light, high humidity, and consistent warmth. The soft, arching fronds look spectacular in a hanging basket positioned above a bath or mounted on a high shelf. Water regularly to keep the compost moist (not waterlogged) and mist between showers if the room doesn't get steamy every day. In the right bathroom, this plant do wells with minimal intervention. Full Boston fern care guide.
Air Plant (Tillandsia)
Air plants are genuinely made for bathrooms. They absorb moisture through their leaves, so a bathroom that gets steamy regularly can largely meet their watering needs. Mount them on a piece of driftwood or a small decorative holder and position them where they'll catch some light from the window. Give them a weekly soak in a bowl of water if the bathroom doesn't get hot and steamy every day. No compost, no watering schedule to remember, just mist and monitor. Full air plant care guide.
Phalaenopsis Orchid
Phalaenopsis orchids, the flat-faced moth orchids you see everywhere in UK supermarkets, actually appreciate bathroom conditions more than most people realise. They like indirect light, warm temperatures, and the humidity a bathroom provides. They grow naturally as epiphytes on tree bark in tropical forests, absorbing moisture from the air, a bathroom with regular showers mimics this well. Water by placing the pot in a tray of water for twenty minutes once a week, then drain fully. Keep them away from cold draughts near the window. Full phalaenopsis orchid care guide.
Prayer Plant (Maranta leuconeura)
Prayer plants love humidity and indirect light, both typically available in a bathroom. Their decorative, patterned leaves fold up at night, and in a humid environment they stay looking lush and well-fed without the constant misting required in a dry living room. Keep the compost consistently moist but not waterlogged, and position them where they get some natural light. They're also non-toxic, which matters less in a bathroom but is still a plus in a household with pets. Full prayer plant care guide.
Spider Plant (Chlorophytum comosum)
Spider plants are adaptable enough to work in almost any room, but they particularly enjoy the humidity of a regularly used bathroom. They're non-toxic, easy to propagate, and their trailing form looks great on a shelf or in a hanging basket near the window. They tolerate the temperature swings that bathrooms experience and don't need much in the way of special care, a moderate watering regime and some indirect light is all they ask. Full spider plant care guide.
Pothos (Epipremnum aureum)
Pothos handles bathroom conditions very well. It tolerates the variable light levels, warm and humid atmosphere, and the occasional missed watering without complaint. Let it trail from a shelf above the bath or pin it up along a wall for a genuinely lush effect. It grows quickly in a warm, humid bathroom and can be trimmed back easily if it gets too long. The golden and marble queen varieties are particularly attractive in bathroom settings, their variegated leaves catching whatever light is available. Full pothos care guide.
Bird's Nest Fern (Asplenium nidus)
Bird's nest ferns have broader, less delicate fronds than Boston ferns, making them a slightly more tough choice for a bathroom where the temperature can drop overnight. They grow from a central rosette and prefer indirect light, a frosted bathroom window is ideal. Keep the compost moist and avoid pouring water into the central crown, which can cause rotting. They're non-toxic and add a structural, bold look compared to the softer texture of Boston or maidenhair ferns. Full bird's nest fern care guide.
Maidenhair Fern (Adiantum)
Maidenhair ferns are notoriously demanding in dry conditions, but in a bathroom they can genuinely be transformed into low-maintenance plants. The high humidity that defeats most owners in a living room is simply provided naturally in a regularly used bathroom. Their delicate, fan-shaped leaflets and wiry black stems are beautiful, and in the right conditions they grow thickly and lushly. Keep them away from direct cold draughts and maintain consistent moisture at the roots. A bathroom is honestly the best place to grow one. Full maidenhair fern care guide.

Frequently Asked Questions
Can plants survive in a bathroom with no window?
Not long-term without a grow light. Plants need light for photosynthesis regardless of how humid the conditions are. A full-spectrum grow light placed on a timer for 12-14 hours per day can substitute for natural light and make a windowless bathroom viable for low-light plants. Without any light source, plants will deteriorate within weeks.
Will shower steam damage my plants?
For the humidity-loving plants on this list, shower steam is beneficial rather than harmful. Very hot steam directed directly at delicate foliage could potentially scorch it, but the general warm humidity from a shower is exactly what these plants prefer. Ensure the room ventilates between showers, completely stagnant humid air can encourage mould in some conditions.
Why do bathroom plants often look better than living room ones?
Because most popular houseplants are tropical species that evolved in humid, warm, filtered-light environments, conditions that are much closer to a busy bathroom than a typical heated living room with central heating running. The humidity reduces leaf tip browning, the warmth encourages growth, and the indirect light suits most tropical foliage plants perfectly.
Can I keep an orchid in a bathroom permanently?
Yes, if the bathroom has enough indirect light. Phalaenopsis orchids do very well in warm, humid bathrooms and can rebloom reliably in the right conditions. The key is ensuring they get enough light, if the window is quite small or north-facing, supplementing with a small grow light during winter months helps maintain good leaf health and encourages flowering.
How do I deal with pests in a humid bathroom environment?
High humidity generally reduces the risk of spider mites (which prefer dry conditions) but can increase the risk of fungus gnats if compost stays too wet. Using well-draining compost, allowing the top of the compost to dry slightly between waterings, and ensuring good air circulation reduces pest problems. Check plants regularly by inspecting the undersides of leaves.
