Spa plants do more than fill an empty corner. In a treatment room, relaxation lounge or reception area, the right plants can soften hard surfaces, add a sense of calm and make a space feel more considered from the moment guests walk through the door.
But choosing plants for a spa is not quite the same as choosing them for home. Warm temperatures, high humidity, low natural light and occasional exposure to steam all need to be considered, alongside the practical reality of busy staff who may not have time for daily plant care.
In this guide, we’ll cover the best plants for UK spas and wellness spaces, where to place them and how to keep them healthy with minimal maintenance. Our recommendations are based on the plants we grow and supply for hospitality and commercial spaces across the UK, with a focus on varieties that can cope with the conditions and demands of a working spa.
What makes a good spa plant?
A spa is a particular set of growing conditions, and not every houseplant will cope with it. When we choose spa plants, we look for five things.
Humidity tolerance. Steam rooms, hydro pools and treatment areas run humid. That suits tropical foliage well. Many humidity loving plants that sulk in a dry living room will thrive in a spa.
Low light tolerance. Spas tend to favour soft, dim lighting for atmosphere. Plants need to hold their colour and shape without direct sun, which is where low light plants earn their place.
A calm look. Green, textural and unfussy. Calming plants with soft fronds or broad, simple leaves suit the mood far better than spiky or heavily patterned specimens.
Low maintenance. Spa staff are busy with clients, so plants that tolerate a missed watering and grow slowly are much easier to keep than thirsty, fast-growing ones.
Safety. Bare feet, treatment beds, and sometimes pets in dog-friendly retreats. Non-toxic, sturdy plants reduce the risk of an accident or a reaction.
The best spa plants for humid treatment rooms
Treatment rooms, steam areas and hydrotherapy suites are the one place where humidity works in your favour, so lean into it. Ferns are the natural starting point. The Asplenium nidus, or bird's nest fern, forms a neat rosette of glossy, bright green fronds and copes well with lower light and warm, moist air. For something more sculptural, the Platycerium bifurcatum, or staghorn fern, can be wall-mounted to save floor space in a compact room, and it reads as living art rather than a potted plant.
Beyond ferns, the wider fern collection gives you a range of leaf shapes and sizes to layer together. Mixing a fine, feathery frond with a broad, glossy one adds depth to a small room without adding clutter. Prayer plants are another strong choice: a Calathea brings patterned, richly coloured foliage and genuinely enjoys the humidity a spa provides. Because these species already sit in moist air, you rarely need to do anything extra to keep them happy, which keeps daily care to a minimum.
One practical note on placement: keep pots off wet floors and away from direct splash from pools or showers. Constant standing water at the roots causes rot, even in plants that love humid air. A raised planter or a shelf keeps the roots healthy while still giving the plant the moist atmosphere it wants.
Calming plants for relaxation areas and reception
Relaxation lounges, waiting areas and reception desks set the first impression, so the planting here should feel restful rather than busy. This is the right spot for calming plants with soft, rounded foliage. A Calathea roseopicta 'Medallion' works well on a side table or shelf, with broad leaves in concentric rings of green that draw the eye without shouting for attention.
Plants for relaxation earn their keep in these spaces because greenery has a measurable effect on how people feel. Research into indoor planting consistently links the presence of plants with a lower sense of stress and a stronger impression of calm, which is exactly the feeling a spa is built to sell. A few well-chosen plants at eye level, where guests actually sit and wait, will do more than a large display they walk straight past.
If your spa is dog-friendly, or you simply want to remove any doubt, build the scheme around pet-safe houseplants. Many prayer plants and ferns are non-toxic, so you can keep the calm, green look without compromising on safety. It is worth checking each species rather than assuming, since a plant that is fine for people is not always fine for animals.
Statement plants for spa lobbies and corridors
Lobbies, corridors and double-height spaces can take a larger plant, and a single well-placed specimen often does more than a scatter of small pots. Palms are the classic answer. The areca palm brings feathery, arching fronds and a soft, tropical feel, while the Kentia palm is one of the most forgiving statement plants there is, holding its form in low light and coping with a degree of neglect.
For floor-standing greenery with real presence, browse the large plants range and choose a size that suits the ceiling height. In tighter or dimmer corridors, the indoor palm collection and other low-light options will hold up where brighter-loving plants would thin out and lose their shape.
Light, watering and air quality
Light is usually the limiting factor in a spa, not humidity. Before you place anything, spend a day noting where daylight actually reaches, then match the plant to the spot rather than the other way round. Species tagged as low light will tolerate dim corners; brighter-loving plants belong near windows or rooflights.
On watering, most spa plants prefer their compost to dry out slightly between drinks, so check with a finger before reaching for the watering can. Overwatering kills far more commercial plants than underwatering. Because a spa is already humid, you do not need to mist; the ambient moisture does that job for you. If air quality is part of your wellness message, the air-purifying plants range is a sensible place to start, though the honest position is that the biggest benefit of indoor plants is how they make a space feel, not dramatic changes to air chemistry.
Keeping plants looking their best
For a small spa, buying outright and assigning care to one staff member is usually the simplest route. Larger sites, or those without anyone to take it on, may prefer a maintenance contract so replacements and upkeep are handled for you. Either way, buy plants at a size close to their final look rather than waiting for small specimens to grow in, and group pots in odd numbers for a more natural arrangement.
Keep leaves wiped clean of dust so they photograph well and continue to work, rotate plants occasionally so they grow evenly, and replace any specimen that has passed its best rather than letting it drag down the room. A tired plant reads as neglect, which is the opposite of what a spa is selling.
