What Is a Garden Sauna?

A garden sauna is a purpose-built outdoor sauna designed for installation in a private garden or backyard. Unlike indoor saunas, these units are self-contained structures that sit outside the home, offering complete separation between living space and wellness space.

Garden saunas typically include:

• A fully insulated sauna cabin
• Benches arranged for comfortable seating
• A heating system (wood-fired or electric)
• Ventilation designed for outdoor use

They can be installed in back gardens, side gardens, patios, courtyards or landscaped outdoor areas. Because they are standalone structures, garden saunas allow homeowners to enjoy authentic sauna bathing without structural changes to the house.

Why Choose a Sauna for Your Garden or Backyard?

Installing a sauna in the garden offers several advantages compared to indoor alternatives.

Privacy & relaxation

A back garden sauna creates a peaceful environment away from household noise and daily distractions. Stepping outside to sauna helps separate relaxation time from everyday routines.

No indoor renovation

There is no need to convert bathrooms, spare rooms or basements. Garden saunas are delivered as complete units, requiring only a suitable base and utility connection if electric.

Year-round use

Modern outdoor saunas are designed for the British climate. With proper insulation and weather-resistant construction, a garden sauna can be used comfortably in all seasons — including winter.

Adds value to your home

Outdoor wellness features are increasingly desirable. A well-installed garden sauna can enhance lifestyle appeal and long-term property value.

Small Garden Saunas – Ideal for Limited Space

Not every garden is large, but that does not mean a sauna is out of reach. Small garden saunas are specifically designed for compact outdoor spaces.

These models are ideal for:

• Townhouse and city gardens
• Courtyards and terraces
• Narrow back gardens
• Properties with limited outdoor footprint

Small garden saunas often accommodate 1–2 people, offering efficient heating, fast warm-up times and lower running costs. Barrel-style saunas and compact cabin saunas are particularly popular choices for smaller gardens due to their efficient use of space.

For homeowners who want the full sauna experience without sacrificing garden usability, compact models provide an excellent balance between size and comfort.

Where Can You Install a Garden Sauna?

A sauna can be installed in most garden environments as long as the base is level and stable.

Common installation locations include:

• Lawns (with a prepared base)
• Wooden decking
• Paving slabs
• Concrete foundations
• Gravel bases with support beams

The sauna should be positioned to allow proper ventilation, safe access and comfortable movement around the structure. Many homeowners choose a discreet location at the back of the garden, creating a quiet retreat that blends naturally into the landscape.

When planning placement, consider:

• Distance from fences and boundaries
• Privacy from neighbours
• Access for delivery and installation

Planning Permission & Considerations

In most cases, garden saunas do not require planning permission, as they fall under permitted development rules. However, there are a few general guidelines to keep in mind:

• Height restrictions may apply, especially near boundaries
• Listed buildings and conservation areas may have additional requirements
• Electrical installations must follow UK safety standards

Because regulations can vary, it is always advisable to check local council guidance if you are unsure. Most standard garden sauna installations proceed without the need for formal permission.

Best Sauna Types for Gardens & Backyards

Different sauna designs suit different garden layouts and personal preferences.

Barrel saunas

Barrel saunas are highly space-efficient and visually distinctive. Their rounded shape promotes even heat circulation and works particularly well in small to medium gardens.

Cabin saunas

Cabin-style garden saunas offer a modern appearance with straight walls and larger bench layouts. They suit contemporary gardens and users who prefer a more spacious interior.

Traditional outdoor saunas

Inspired by Finnish sauna culture, these models focus on authentic heat, simplicity and durability. They work well in larger gardens where space allows for a dedicated wellness area.

Each type can be adapted for garden use and paired with either wood-fired or electric heating systems.

Using a Garden Sauna All Year Round

Outdoor saunas are not limited to summer use. In fact, many sauna enthusiasts consider winter bathing to be the most rewarding.

High-quality garden saunas feature:

• Thick insulated walls
• Weather-resistant timber
• Roof systems designed for rain and snow

Cold outdoor air combined with sauna heat enhances circulation and deep relaxation. With proper construction, a garden sauna remains comfortable and efficient throughout the year.
