Can Plants Survive in Windowless Bathrooms?

Plants can indeed survive and even thrive in windowless bathrooms, provided they are given the appropriate care and environmental conditions.

Also, it is a wise take to pick those plants that can thrive in limited light and highly humid conditions, something that most bathrooms provide.

Growing plants in a windowless bathroom don’t involve any special technique but a few tricks that must make the growing conditions favorable for its growth. 

1. Provide Artificial Lighting


As we all know, every plant needs some sort of light source to photosynthesize, and since your bathroom lacks natural sunlight, artificial lighting can be the solution. These are the most viable options that cover almost every kind of plant growth.

  • Fluorescent Lights: These are energy-efficient and provide a broad spectrum of light suitable for plants that do well in minimal or low light sources.
  • LED Grow Lights: Energy-efficient, long-lasting, and produce a suitable spectrum of light for plant growth. They come in various shapes and sizes to fit your bathroom space, best for vining houseplants such as Pothos or Philodendrons.
  • Light-Emitting Plasma (LEP): This technology produces a full spectrum of light that closely mimics sunlight. LEP lights are more expensive than other options, but they are energy-efficient and long-lasting. It is more suited for plants that require a considerable amount of light to thrive, such as flowering or variegated species.

Note: Do remember to fix the light source at a distance of 6-12 inches away from the plants, as too much intensity can burn their leaves and stunt their growth. Also, ensure to pick the appropriate light source that suits your plant requirements.

2. Install Reflective Surfaces

Maximize the available light in your windowless bathroom by incorporating reflective surfaces. These surfaces can help distribute artificial light more evenly and increase its intensity. You can achieve this by using mirrors, metallic surfaces, or installing reflective film on walls or shelves near your plants.

3. Change Their Place Temporarily

If you notice the plants growing leggy or starting to wilt, move them to a sunnier spot for just a few hours each week to provide a more natural growing environment. A few hours of sunbath can stimulate their growth, rejuvenate their leaves, and promote the development of healthy roots.

However, do not expose them to harsh afternoon sunlight or prolonged exposure all at once, as this sudden fluctuation can do more harm than good.

4. Reduce Watering

Bathrooms have a humid atmosphere which keeps the soil in pots moist for longer periods. This increases the risk of overwatering. To avoid it, reduce the frequency of watering the plants. Check the soil moisture by sticking your finger about an inch into the soil and water only when it feels dry to the touch.

When watering, make sure to water the soil thoroughly and allow the excess water to drain out of the pot. Avoid letting your plants sit in standing water, as this can cause root rot and other issues.

5. Maintain a Consistent Temperature


Most low-light plants prefer temperatures between 65-75°F (18-24°C), which is comfortable for both plants and humans. Be cautious of sudden temperature fluctuations caused by hot showers or drafts, as they can stress your plants and hinder their growth. To ensure optimal temperature conditions, use a thermometer to monitor the bathroom temperature and make adjustments as needed.

6. Use Low Strength Fertilizer

Since plants in windowless bathrooms don’t get a natural light source, they grow at a slower pace and hence require less frequent fertilization. Choose a balanced, water-soluble fertilizer and mix it at half the recommended strength. Apply the fertilizer every 8-10 weeks during the growing season to provide essential nutrients for your plants.

Avoid over-fertilizing, as it can cause salt buildup in the soil and damage your plants.

7. Keep an Eye for Pests


Pests can be a matter of concern in windowless bathrooms as they thrive more in moist environments. Regularly inspect your plants for common pests such as spider mites, aphids, and mealybugs.

If you notice any pests, remove them manually using a soft cloth or cotton swab. To stay on the safe side, spray your plants with neem oil or insecticidal solution every 4-5 weeks. This will bar the chances of persistent infestations that might become even more active in the lack of air circulation.

8. Keep them Tidy

Regular pruning and cleaning are crucial for maintaining the health and appearance of your bathroom plants, as they already are prone to pest infestation in the moist atmosphere of bathrooms. Prune any dead or yellowing leaves with clean, sharp scissors to encourage healthy growth and prevent the spread of diseases.

Regularly wipe the leaves with a damp cloth to remove dust and grime, which can hinder the plant’s ability to photosynthesize. Additionally, cleaning the leaves also helps maintain the aesthetic appeal of your plants, contributing to a refreshing bathroom environment.
