Creating Your Own Private Retreat
How to Design a Luxury Garden Wellness Space
For many people, wellness is no longer something reserved for a spa visit or a weekend away.
A quiet swim before work, a cold plunge after training or time spent relaxing in a sauna can become part of everyday life when the right facilities are available at home.
A bespoke garden wellness room can bring these experiences together in a space designed around your property, your routine and the way you want to unwind.
From private swimming pools and cold water immersion to saunas, changing facilities and relaxation areas, there is plenty to consider when planning a wellness space that looks exceptional and works properly throughout the year.
So where should you start?
What is a garden wellness room?
A garden wellness room is a purpose designed building that brings some of the facilities you might associate with a private spa, health club or luxury hotel into your own garden.
For one household, that might mean a compact room with a sauna, cold plunge and shower. For another, it could be a larger building overlooking an outdoor swimming pool, with changing facilities, a gym and somewhere comfortable to relax.
There is no single layout that suits everyone. The most important consideration is how you actually want to use the space, rather than simply trying to fit as many features into it as possible.
Can you have a swimming pool in a garden room?
Yes, but a building containing an indoor swimming pool needs to be designed as a specialist pool environment from the outset.
A swimming pool introduces far more than the space occupied by the water itself. You need to consider the pool structure, heating, filtration, water treatment, drainage, safe access and the equipment needed to manage humidity inside the building.
A conventional insulated garden room should not simply have an indoor pool added to it without the right technical design. Moisture control, materials, ventilation and building details all need particular attention.
Depending on the project, Swift can help develop the surrounding bespoke building and coordinate its design requirements with specialist pool suppliers and installers.
What type of swimming pool works best in a garden wellness space?
The answer depends on whether you want to swim for exercise, spend time with family or simply enjoy being in the water.
Some options to consider include:
- Traditional swimming pool: Suited to clients who want a larger swimming area and have the garden space and budget to accommodate it.
- Swim spa: A more compact option that uses a water current to allow swimming in place, often appealing where a full length pool would be impractical.
- Plunge pool: Usually smaller and more focused on cooling off or relaxing than swimming lengths.
- Cold plunge tub: A dedicated cold water immersion system, designed for brief dips rather than swimming.
These are not interchangeable products. Each brings different requirements for space, access, maintenance, electricity and water treatment, so choosing the right one early can make the wider project much easier to design.
Can a wellness garden room sit beside an outdoor swimming pool?
Absolutely, and for many properties this can be a particularly attractive arrangement.
Rather than putting the swimming pool inside the building, a bespoke garden room could overlook an outdoor pool and provide everything needed around it.
That might include changing facilities, a shower, a sauna, a lounge area, storage for towels and pool accessories or a sheltered place to sit between swims.
Large glazed doors can help connect the two spaces visually, while suitable decking, paving and landscaping can make the entire area feel like one considered design.
It is important to allow enough room for safe circulation around the pool, weather appropriate surfaces and practical access for servicing and cleaning.
Can you add a cold plunge to a garden room?
Yes. Cold plunge systems can be incorporated into a bespoke wellness project, either within a suitable wet area or outside the building as part of an adjoining terrace or courtyard.
The best position will depend on the particular plunge unit, how frequently it will be used and whether you want it beside a sauna, shower or gym.
Before deciding where it should go, it is worth considering the filled weight of the equipment, electrical requirements, water supply, drainage, splash protection and access for routine maintenance.
A cold plunge can be a relatively small feature, but it still needs proper planning to work safely and reliably.
Can you combine a sauna and cold plunge in the same wellness room?
Yes, and the two can work very naturally together in a private wellness layout.
A sauna and cold plunge can be positioned close enough to make moving between them convenient, while still keeping appropriate separation between electrical equipment and wet areas.
You might also want a shower, seating area and somewhere to store robes and towels. Non slip flooring, easy entry and exit from the plunge and a clear circulation route are particularly important.
The aim should be to make the space feel comfortable and effortless to use, without compromising on the practical requirements of either system.
What are the benefits of cold water immersion?
Many people enjoy cold water immersion because they find it invigorating and like incorporating it into their exercise or relaxation routines.
There is research into its effects on perceived recovery and muscle soreness, but claims about wider health benefits should be treated cautiously. Cold plunging is not a guaranteed way to improve health and it is not suitable for everyone.
Sudden immersion in very cold water can trigger a cold shock response, including changes in breathing, heart rate and blood pressure. Anyone with a heart condition or other relevant medical concern should seek professional medical advice before trying it.
For a home wellness space, sensible access, safe operation and an appropriate temperature control system matter much more than chasing the coldest possible water.
Does a cold plunge need to be outdoors?
Not at all. Some people prefer an outdoor plunge because it feels connected to the garden, especially when positioned beside a sauna or covered terrace. Others prefer to keep the entire experience indoors for privacy and protection from the weather.
Both approaches can work, provided the equipment is suitable for its location.
An indoor installation needs adequate splash management, ventilation and appropriate wet area finishes. An outdoor installation needs consideration of weather exposure, drainage, suitable electrics and any manufacturer requirements for frost protection.
Can a garden wellness room include a sauna, steam room or shower?
Yes, although each facility has different technical requirements.
A sauna requires the correct heater installation, clearances and ventilation. A steam room introduces substantial moisture and needs a purpose designed, waterproof enclosure and suitable ventilation arrangements.
Shower rooms and changing areas can also be incorporated, with water supply, waste connections and easy to clean finishes considered from the beginning.
These facilities should be designed in conjunction with the relevant specialists rather than treated as standard furniture or accessories added after construction.
How do you prevent condensation and damp around an indoor pool?
This is one of the most important design questions for any indoor swimming pool.
Warm pool water naturally releases moisture into the air. Without an appropriate system to control temperature and humidity, condensation can develop on glazing and other cooler surfaces, potentially affecting the building over time.
A pool hall therefore needs specialist ventilation and dehumidification, suitable building materials and careful detailing to control moisture movement through the structure.
This is different from fitting ordinary air conditioning to a conventional garden office or gym. The pool environment must be addressed as part of the building design, not left until installation is almost complete.
What groundwork and services does a swimming pool or cold plunge require?
Water is heavy, and that makes the groundwork and structural design especially important.
A pool, swim spa or plunge needs a foundation or support arrangement designed for its filled weight, the equipment itself and the people using it. Ground conditions, access and the position of any existing drains or services can all influence the solution.
Other considerations may include:
- Electrical capacity and safe power connections
- Water supply and suitable drainage arrangements
- Pool heating, filtration and treatment equipment
- Plant room space and maintenance access
- Slip resistant surfaces and suitable waterproof finishes
- Delivery access for larger preformed pools or spa units
For larger projects, the plant and services can take up a meaningful amount of space, so they should be incorporated into the initial layout rather than hidden as an afterthought.
How much space do you need for a private wellness room?
There is no standard size because the answer depends entirely on what you want to include.
A room housing a sauna, shower and compact cold plunge could have a very different footprint from a garden building designed around a full swimming pool or swim spa.
It is not just the equipment dimensions that matter. You also need comfortable space to move around, open doors, access the equipment for servicing and relax without feeling cramped.
At Swift Unlimited, we would look at the available garden space, your priorities and your overall budget before establishing a layout, rather than starting with a predetermined building size.
Can you use a garden wellness room all year round?
Yes, provided the building and its systems have been designed for year round use.
A well insulated structure, appropriate heating and cooling, good glazing and suitable ventilation can make the indoor spaces comfortable through the changing seasons.
For pools and plunges, the equipment also needs to be suitable for the intended operating conditions. Outdoor water systems may require specific measures for cold weather, while indoor pool spaces need ongoing humidity management.
The objective is to create a facility that feels just as inviting on a dark winter evening as it does on a summer afternoon.
How important are glazing and privacy in a wellness garden room?
They are both worth thinking about from the beginning.
Large aluminium glazed doors can provide garden views, natural light and a strong connection to an outdoor pool or landscaped courtyard.
However, privacy may be particularly important if you are swimming, using a sauna or moving between facilities. Glazing can be balanced with more solid elevations, screening, planting and careful positioning within the garden.
For indoor pools, glazing also needs to be considered alongside the specialist temperature and humidity design to help manage condensation.
Can you combine a home gym with a swimming pool or wellness room?
Yes. A combined gym and wellness building can work very well when the different activities are planned as part of one coherent layout.
For example, a dry training area could have direct access to a shower, sauna and cold plunge, with a separate relaxation space overlooking the garden.
The key is to keep wet and dry zones appropriately separated, choose flooring that suits each use and allow for equipment loads, ventilation and safe circulation.
A room designed for heavy gym equipment will also have different structural and acoustic considerations from a quiet treatment or relaxation area.
Do swimming pools and wellness garden rooms need planning permission?
Not always.
In England, certain domestic swimming pools, pool houses and sauna buildings can fall within permitted development rights, provided the relevant conditions are met.
The position in the garden, the height and size of the structure, proximity to boundaries, existing buildings and any restrictions affecting the property can all make a difference.
An outdoor swimming pool and an enclosed pool hall may also have different Building Regulations considerations. Even where planning permission is not needed, that does not automatically mean the entire project is exempt from Building Regulations or other approvals.
For that reason, planning and compliance should be checked at an early stage rather than assuming a garden wellness building can always be constructed without permission.
How much does a bespoke swimming pool or wellness garden room cost?
There is no one size fits all answer.
The cost of a bespoke wellness project will depend on the building dimensions, the choice of swimming pool or plunge equipment, glazing, groundwork, wet areas, specialist ventilation and the distance to existing services.
An outdoor pool with a separate garden room will have a different scope from a fully enclosed indoor swimming pool building. Adding saunas, showers, bespoke cabinetry and specialist finishes will also influence the overall cost.
It is worth establishing a realistic complete project budget at the start, including any specialist equipment and installation that may be supplied separately.
Because Swift’s buildings are bespoke, we can explore which features matter most and develop the design around those priorities.
What should you consider before designing a garden wellness space?
A few early decisions can make a considerable difference to the finished project:
- Whether you want to swim, recover after training, relax or combine all three
- Which facilities are essential and which are optional
- Whether the pool or plunge should be indoors or outdoors
- How much privacy you want from neighbouring properties
- How the building will be accessed throughout the year
- Where water, drainage and electrical connections can come from
- What space is needed for plant, storage, changing and maintenance
- Whether any planning permission or other approvals will be required
- Your overall budget, including specialist equipment and installation
These are much easier to address at the design stage than after the building or landscaping is complete.
Can Swift Unlimited design a wellness garden room around a swimming pool?
Swift Unlimited designs and builds fully bespoke garden rooms, gyms, studios, entertainment spaces and annexes across the UK.
That flexibility makes it possible to create a dedicated wellness building or a wider garden design that brings together swimming, exercise and relaxation.
Whether you are considering a sauna and cold plunge retreat, a luxurious room overlooking an outdoor swimming pool or a more extensive indoor pool project, the starting point is understanding exactly how you want the space to work.
We can develop the building layout, glazing, finishes and supporting spaces around those requirements, working with specialist pool and wellness equipment providers where necessary and agreeing the scope of works for each element.
The goal is not simply to add more facilities to the garden. It is to create a space that you genuinely look forward to using.
A truly bespoke wellness room should feel like a natural extension of your lifestyle, with the freedom to switch off, recharge and enjoy your own private retreat without leaving home.
