Bathroom Plants

Bathrooms are simultaneously the easiest and the hardest room in a house for plants. Showers raise the humidity that tropical species crave, though NC State Extension notes the rise lasts only for short spurts and that foliage plants need consistent humidity. Most bathrooms also have either no window at all or a small frosted window with very limited light. Successful bathroom plants are species that tolerate both ends of that spectrum.

The real challenge

Two things kill most bathroom plants: low light and over-zealous watering by owners who assume "humid room = needs more water." In reality, cooler, more humid air lowers the rate at which plants lose water (per NC State Extension), so most bathroom plants need LESS frequent watering than the same plant in a dry living room. Cold drafts from exhaust fans in winter can also stress tropical species.

Measure your light first

Measure your bathroom’s light before buying, with a light meter or a smartphone light-meter app (NC State Extension notes some apps are free). NC State classes 25 to 74 foot-candles as low light, 75 to 149 as medium and 150 to 999 as high (the levels needed to maintain growth), and says spaces lit only by artificial light are usually low-light situations. In low light, stick to snake plant, ZZ plant and pothos. In medium light, add philodendron, peace lily and prayer plant. Boston fern, calathea and anthurium want bright, indirect light (per NC State Extension), which few bathrooms provide.

Top 5 picks

  1. 1
    Boston Fern

    Boston ferns need high humidity, moist soil and bright, indirect light, per NC State Extension, which suggests placing them near kitchens and bathrooms for the higher humidity. A bathroom with even one bright window can supply all three.

  2. 2
    Snake Plant

    For windowless bathrooms with only overhead light, snake plants survive on minimal photosynthesis and tolerate the humidity swings perfectly.

  3. 3
    Pothos

    Pothos prefers bright, indirect light but survives for long periods in low light, per NC State Extension, so it handles most bathroom light levels. Trailing them off a shelf or curtain rod works beautifully.

  4. 4
    Calathea

    Calathea orbifolia needs humidity of at least 60%, per NC State Extension, and low humidity browns the leaf edges. Most living rooms run far drier than that. Place it near the window for medium indirect light.

  5. 5
    Prayer Plant

    Same humidity benefit as calathea but smaller and slightly more forgiving with low light. Their fold-up nightly movement is also a fun bathroom curiosity.

What NOT to buy

Avoid succulents (jade plant, aloe, echeveria, haworthia) entirely — the humidity can rot them. Skip fiddle leaf figs and bird of paradise (they need stable, bright light a bathroom rarely provides). Avoid cacti for the same reason as succulents.

Care adjustments for this environment

Water less often than the species tag recommends: NC State Extension notes that high temperatures and low humidity call for more frequent watering, and cooler, more humid air for less. Wash leaves every two or three months, the interval NC State Extension gives for houseplants, to remove dust and soap-spray residue. Check for fungal issues (black spots, white mold on soil) when you water; bathrooms with poor air circulation can grow mold quickly. Open the door after showers if the room stays steamy.
