Luxury Outdoor Saunas by Heritage Sports
Saunas are valued for their wellbeing, relaxation and recovery benefits, making them a popular addition to private gardens, wellness retreats and premium leisure spaces. At Heritage Sports, we design and build bespoke outdoor saunas that combine modern design with exceptional thermal performance.
Our saunas are constructed using high-performance Structural Insulated Panels (SIPs), providing excellent insulation, structural strength and efficient heat retention for reliable year-round use. Finished with contemporary external cladding systems, each sauna is designed to sit comfortably within its surroundings while delivering a calm, high-quality wellness experience.
A Heritage Sports sauna is designed for those who value performance, longevity and considered design. Built using high-performance SIPs construction, our saunas offer excellent insulation, fast heat-up times and efficient heat retention, making them ideal for year-round use in the UK climate.
Each sauna is designed and built in Britain, using durable materials and contemporary cladding systems to ensure long-term reliability and a refined finish. With flexible layouts, glazing options and integrated features such as outdoor showers or changing areas, Heritage Sports saunas are tailored to suit private gardens, wellness retreats and premium leisure environments.

Structural Insulated Panels (SIPs) offer significant advantages when used in sauna construction, particularly in terms of thermal performance, efficiency and long-term durability. For a space designed to heat quickly and retain warmth, SIPs provide an ideal building solution.
The high level of insulation within SIPs allows saunas to heat faster and maintain consistent temperatures, reducing energy use and improving overall efficiency. Their airtight construction helps prevent heat loss, while the structural strength of the panels ensures a robust, stable building capable of withstanding frequent temperature changes and moisture-rich environments.
By using SIPs, Heritage Sports saunas deliver reliable year-round performance, lower running costs and a comfortable, controlled internal environment — all within a clean, modern structure designed to last.
