The PortaSauna HEXXL is the large-format model for buyers who want a proper group sauna experience without building a permanent sauna cabin. Designed for outdoor use, it combines authentic wood-fired heat with a portable insulated structure, making it a strong option for gardens, events, retreats, wellness businesses, and social sauna sessions.
Why the HEXXL stands out
-
Large group capacity: designed to seat around 8–10 adults comfortably, making it ideal for families, events, retreats, and commercial-style use.
-
Authentic sauna performance: wood-fired heat, sauna stones, and steam give you the feel of a real traditional session rather than a low-heat substitute.
-
Portable but substantial: much easier to site and move than a fixed cabin sauna, while still delivering a serious outdoor sauna setup.
-
Fast assembly: designed to go up quickly, so it suits buyers who want flexibility as well as performance.
Built for outdoor use
-
Insulated fabric structure: helps retain heat and improve performance in cooler weather.
-
430 stainless steel stove: included for reliable wood-fired heating and strong sauna temperatures.
-
Durable frame system: built around reinforced fibreglass poles and steel joiners for stability.
-
Dual access points: practical for larger group use, ventilation control, and easier movement in and out of the sauna.

Who it is for
This is the model to choose if you want a portable sauna that can genuinely serve groups. It is particularly well suited to garden entertaining, wellness retreats, contrast therapy setups, hospitality use, and buyers who want something more commercially capable than a smaller home sauna tent.
Before you order
The HEXXL needs a flat, stable outdoor surface and safe clearances around the unit. Because of its larger size, it is worth planning access, positioning, and how you want to use it before delivery — especially if it will be used for regular group sessions or business purposes.
Bottom line
The PortaSauna HEXXL is a serious portable wood-fired sauna for people who want scale as well as flexibility. If the standard portable sauna market feels too small or too lightweight, this is the model that gives you a much bigger, more usable group sauna experience.
