Choosing the Right Type of Outdoor Sauna for Your Garden

Outdoor saunas are becoming increasingly popular across the UK, with more homeowners adding them to gardens to support relaxation, health, and overall wellbeing. Designed for year-round use, outdoor saunas offer a private, calming escape while enhancing outdoor living spaces.

Choosing the right outdoor sauna starts with understanding the different heating types, shapes, and sizes available in the UK market. Each option suits different lifestyles, spaces, and budgets.

Traditional Wood-Fired vs. Electric vs. Infrared Saunas

Outdoor saunas generally fall into three heating categories.
Each offers a different experience and level of convenience.

Wood-Fired Saunas: The Authentic, Off-Grid Experience

Wood-fired saunas provide a traditional Finnish-style experience and operate independently of electricity. They are valued for their natural heat, atmosphere, and suitability for remote garden locations.

However, they require regular firewood use and more hands-on operation.

Electric Saunas: Modern Convenience and Temperature Control

Electric saunas are the most common choice in the UK due to their ease of use and precise temperature control. They heat quickly, require minimal maintenance, and integrate well into residential gardens with electrical access.

Infrared Saunas: Energy-Efficient Heat Therapy

Infrared saunas use radiant heat rather than heating the air. They operate at lower temperatures and are energy-efficient. This option appeals to users focused on muscle recovery and gentle heat therapy.


Popular Sauna Shapes and Designs for UK Gardens

Beyond heating type, the shape and design of an outdoor sauna can influence heat efficiency, capacity, and visual appeal.

Barrel Saunas: Best for Quick Heating and Air Circulation

Barrel saunas are popular in the UK due to their efficient heat circulation and fast warm-up times. Their curved design allows hot air to move evenly, making them suitable for smaller groups.

Cabin and Cube Saunas: Maximising Interior Space and Luxury

Cabin and cube-style saunas offer straight walls and more usable interior space.
These designs are often chosen for family use or those wanting extra features such as panoramic windows or integrated changing areas.

Vertical Saunas: The Best Space-Saving Solutions for Small Gardens

Vertical saunas are designed for compact outdoor spaces.
With a smaller footprint and upright layout, they are ideal for urban gardens while still delivering a full sauna experience.

Essential Considerations for the UK Climate and Laws

The UK climate and regulatory environment play a key role when installing an outdoor sauna.

Durability and Wood Selection for British Weather

Outdoor saunas must withstand frequent rain, temperature changes, and humidity.

Proper insulation is essential for maintaining heat efficiency throughout the year.
This is particularly important during colder months.


UK Planning Permission and Installation Requirements

Before installation, homeowners should consider legal and technical requirements.

Do You Need Planning Permission for a Garden Sauna?

In most cases, outdoor saunas fall under permitted development.
This applies provided they meet size and placement guidelines.
Restrictions may apply in conservation areas or for listed properties.

Electrical Foundations: 13amp Plug-and-Play vs. 32amp Hardwiring

Smaller electric saunas may run on a standard 13amp supply.
Larger models often require 32amp hardwiring by a qualified electrician.

Base Requirements: Concrete, Decking, or Gravel Foundations

A stable, level base is necessary to support the sauna and ensure longevity.
Common options include concrete, decking, or compacted gravel.
