Bathroom mould is common in many British homes, as humidity and dampness create the perfect environment to thrive. However, you can combat these issues and make your bathroom a more relaxing and green space with plants.
James Roberts, Director at luxury bathroom supplier Sanctuary Bathrooms, reveals which plants can help absorb excess moisture, improving air quality and reducing the risk of mould growth. James said: “Bathrooms are naturally high in humidity due to steam from showers and baths, which makes them a prime spot for mould. However, houseplants thrive in these conditions and can help regulate moisture levels, making them a stylish and practical addition to any bathroom.
James continued: “As biophilic design and bringing nature indoors continue to dominate bathroom trends in 2025, incorporating greenery into your bathroom not only serves a functional purpose but also enhances the space aesthetically.”
9 houseplants to combat bathroom mould
Air plants
These interesting plants are low maintenance and thrive in humid environments, making them perfect for bathrooms. They flourish in temperatures between 10C and 32C with 40-60% humidity levels, often leading to dampness and mould. By absorbing excess moisture from the air, air plants help regulate humidity and create a fresher space.
Spider plants
These hardy plants are almost impossible to kill and will tolerate a lot of neglect; they also thrive in the low light and fluctuating temperatures common in bathrooms while purifying the air and helping to regulate humidity and remove airborne toxins
Ferns
Ferns love humidity, which is found in bathrooms. Their ability to absorb moisture from the air helps reduce dampness, preventing mould from thriving. They’re also well-suited to low-light conditions, making them an easy-care option.
Bamboo
Naturally water-resistant, bamboo thrives in humid conditions where other plants might struggle. It requires minimal light, making it an excellent choice for smaller bathrooms, WCs, and spaces with limited natural daylight.
Peace lilies
These elegant white-blooming plants are among the best for removing mould and purifying the air. They thrive in low light and adapt well to fluctuating humidity levels, absorbing mould spores and airborne toxins.
Aloe vera
Aloe vera naturally thrives in humid environments, drawing moisture from the air and reducing the need for frequent watering. Its powerful air-purifying properties make it an effective plant for keeping bathroom air fresh while preventing mould buildup.
Orchids
In addition to adding a gorgeous pop of colour to your space with their varied blooms, orchids work to improve air quality and regulate moisture, making them a stylish and functional addition to a mould-free space.
English ivy
This plant flourishes in high humidity conditions. Although it prefers bright light, it can adapt to low light and varying temperatures, making it a versatile, low-maintenance choice. Its natural air-purifying properties help remove airborne pollutants and excess moisture, reducing the risk of mould growth in your bathroom.
Snake plants
Snake plants are perfect for smaller bathrooms with limited light. They also thrive in high humidity, helping absorb moisture and filter out mould spores and chemicals in bathroom cleaning products. With their sleek, structured leaves, they bring a modern, low-maintenance touch to any bathroom.
