Bespoke Garden Saunas Designed Around You

There is no single garden sauna design that suits every property.

We create bespoke outdoor saunas in different styles, layouts, materials and finishes, allowing the building to complement both the garden and the architecture of the home.

A sauna can be designed as a standalone garden feature, incorporated into a terrace or positioned as part of a larger outdoor wellness and entertaining space.

Depending on the project, we consider positioning, access, privacy, glazing, ventilation, surrounding landscaping and connections with other outdoor features from the beginning.

For projects where visual planning is beneficial, a bespoke 3D design can help show how the sauna and surrounding outdoor space will work together before construction begins.

Garden Sauna Styles & Finishes

The appearance of a garden sauna can vary significantly depending on the property and the style you want to achieve.

We can create contemporary architectural designs, more traditional sauna-inspired spaces and bespoke structures that combine different materials and finishes.

Exterior options can include architectural cladding, Millboard products, contemporary panels and other suitable outdoor finishes, while glazing can be incorporated to introduce natural light and create a stronger connection with the surrounding garden.

Where appropriate, we can also incorporate steel construction as part of the structural design.

The materials and construction method are selected around the individual project rather than applying the same specification to every sauna.

Sauna Interiors

The interior is where the character and atmosphere of a sauna really come to life.

We can create warm, comfortable interiors using suitable sauna-grade timbers, with the species and finish selected around the desired appearance and sauna specification.

Depending on the design, interiors can incorporate bespoke benches, backrests, glazing, feature walls, discreet lighting and practical storage.

Seating layouts can be tailored to the available space and intended use, from more intimate private saunas to larger family or commercial environments.

Careful attention is given to the details that influence both comfort and appearance, creating an interior that feels considered rather than simply functional.

Sauna Heating Options

Different sauna designs and users require different heating solutions.

Depending on the project and installation requirements, we can incorporate suitable electric or wood-burning sauna heating systems, with the final specification selected around the sauna design and intended use.

Heating, controls and ventilation are considered together to help create an appropriate and comfortable sauna environment.

Where specialist electrical or other connections are required, these can be coordinated with appropriately qualified trades as part of the wider project.

Insulation, Ventilation & Moisture Management

A garden sauna needs more than an attractive interior.

The wall construction, insulation, vapour management and ventilation all play an important role in how the sauna performs.

Depending on the chosen construction, we incorporate appropriate insulation, vapour control, ventilation and moisture-management systems as part of the overall build.

Drainage and the surrounding external construction are also considered where relevant.

These elements are planned around the individual sauna rather than relying on a generic garden-building specification.

Panoramic Glazing & Architectural Details

Glazing can completely change the character of a garden sauna.

Depending on the design, glazed doors, windows or larger glazed sections can introduce natural light and provide views into the surrounding garden while maintaining the warm atmosphere of the sauna interior.

For properties where privacy is important, glazing can be coordinated with planting, privacy screens and the position of the sauna.

Exterior finishes, frames and architectural details can also be coordinated with surrounding garden features to create a more unified appearance.

Garden Saunas with Millboard Decking

As Approved Millboard Installers, we can design the sauna and surrounding Millboard decking as one complete outdoor space.

This allows the sauna position, decking layout, access, steps, seating, lighting and surrounding features to be considered together from the beginning.

Where appropriate for the decking project, we can construct galvanised steel subframes measured, cut, fabricated, welded and assembled on site, providing a strong and durable structure beneath the surrounding terrace.

The result is a sauna that feels integrated into the wider garden rather than simply positioned on an existing terrace.

Complete Outdoor Wellness Spaces

A garden sauna can become the centrepiece of a much larger outdoor wellness area.

Depending on the project, we can combine the sauna with outdoor showers, hot tubs, cold plunge areas, relaxation terraces, bespoke seating, privacy screens, planting and integrated lighting.

These features can be arranged to create a natural journey between heating, cooling and relaxation areas while maintaining privacy and visual connection with the garden.

By considering the complete environment from the beginning, individual features can work together as one cohesive outdoor retreat.

Saunas with Pergolas & Covered Areas

A bespoke pergola or covered structure can also form part of a garden wellness area.

Depending on the design, pergolas can help define relaxation spaces around the sauna while providing shade, shelter or additional privacy.

The pergola, sauna, decking and surrounding seating can be designed together to create a more architectural and cohesive outdoor environment.

Different pergola styles and roof systems can be considered depending on the individual project.

Privacy Screens & Landscaping

Privacy is particularly important when designing an outdoor sauna or wellness space.

We can incorporate privacy screens, architectural screening, planters and landscaping to create a more secluded environment without unnecessarily separating the sauna from the rest of the garden.

Planting can soften architectural elements while screens can provide more immediate privacy around entrances, showers, hot tubs and relaxation areas.

Considering these elements during the design stage creates a more natural and comfortable finished space.

Integrated Lighting

Lighting plays an important role in creating the right atmosphere inside and around a garden sauna.

Depending on the project, lighting can be incorporated into sauna interiors, surrounding decking, steps, seating, planters and other landscape features.

Interior lighting can create a calm and relaxing atmosphere, while external lighting helps connect the sauna with the surrounding garden after dark.

Planning lighting during the design stage also allows services to be integrated discreetly wherever possible.

Residential & Commercial Garden Saunas

Our bespoke saunas can be designed for both residential and commercial environments.

Residential projects can range from private garden saunas to complete wellness areas incorporated into larger outdoor living transformations.

Commercial applications can include hospitality, wellness and other leisure environments, with the specification adapted to the requirements of the individual project.

We work with homeowners, architects, garden designers, contractors and property developers, allowing the sauna to be considered as part of the wider architectural and landscape design.
