Outdoor Box sauna with a spacious relax & changing room

Experience the perfect balance of space, comfort, and style with our 5XL Box sauna with relax room. Designed as a premium outdoor sauna, it combines the traditional warmth of natural wood with modern functionality. The result is a generous wellness space that easily accommodates up to 4-8 people – perfect for family time, gatherings with friends, or simply enjoying the luxury of more room for yourself.

The structure of this sauna box is crafted from durable spruce wood, while its benches are made from high-quality thermowood. This thermally treated wood is processed using only heat and steam – no chemicals – making it safe for people and ideal for high-temperature environments.

Thermowood benches offer several advantages:
→ They remain aesthetically pleasing for years without exuding resin.
→ Their darker surface is less prone to staining compared to light-coloured wood.
→ They stay comfortable to the touch, even at higher heat levels.

In the 5XL Box outdoor sauna, benches are arranged on two levels – giving you the freedom to enjoy the intense heat of the upper bench or the gentler warmth of the lower one, just as sauna enthusiasts prefer.

Unlike smaller saunas, the 5XL model includes not only a large sauna room but also a spacious relax & changing room. This additional space adds comfort before and after your sauna session – whether you want to cool down, share tea, or simply relax in peace. For those who wish to add even more light and openness, optional tinted glass windows are available for the sauna or relax room front wall. These windows enhance the design, allow you to enjoy views of your garden, forest, or lakeside, and still maintain privacy.

To complete your sauna experience, you can select the heating system that best fits your lifestyle. The 5XL Box sauna can be equipped with a wood-burning stove for a traditional, authentic steam experience, or a modern electric heater for easy, precise control. We offer premium stoves from Harvia, HUUM, and Stoveman – trusted brands known for their efficiency, reliability, and design. Whether you prefer the ritual of lighting a fire or the convenience of electricity, your sauna is tailored to your needs.

The 5XL Box sauna with relax room is proof that bigger truly means better – a smartly designed sauna box that brings together space, wellness, and elegance into one complete backyard retreat.

PREPARING THE FOUNDATION

The foundation for the sauna must be even and load-bearing. The sauna’s construction is strong and stable, so the foundation can be made of concrete blocks, stones, timber boards, a terrace, or pavement. Damages caused by an uneven foundation are not covered under the warranty. Avoid placing the sauna directly on grass or soft ground. Vegetation can obstruct airflow, retain moisture, and speed up rotting.

The seller offers a 24-month manufacturing warranty against production defects, starting from the date of delivery. The warranty does not cover wooden components.
Heaters come with warranties from their respective manufacturers.

NOTE. Commercial use of the sauna is covered by a 3-month warranty.


The warranty does not cover the following
Natural characteristics of wood

→ Knots, minor cracks, and color variations in the raw spruce wood.
→ Expansion, contraction, or warping due to natural wood behavior.
→ Resin leakage or minor sap spots.

Aging and wear

→ Surface scratches, dents, or general aging of the materials.
→ Discoloration or fading from UV exposure.
→ Wear on accessories like door handles, hinges, or seating.

Maintenance and care issues

→ Mold, mildew, or rot due to lack of proper maintenance or insufƒOcient ventilation.
→ Damage resulting from failure to clean and maintain the sauna according to care guidelines.

Structural and installation concerns

→ Misalignment or structural instability caused by improper foundation or placement on uneven ground.
→ Changes made to the structure, such as drilling, cutting, or adding non-approved parts.
→ Overloading weight capacity on benches, shelves, or other structural components.

Environmental and external factors

→ Damage caused by insects, rodents, or other pests, including failure to implement proper pest
control measures.

Heater and equipment issues

→ Heater malfunctions due to improper installation, voltage issues, or failure to use a certified
professional installer.
→ Damage resulting from the use of unauthorized sauna heaters or non-approved equipment

For warranty claims, contact the seller. Defective components will typically be replaced within 30 days of proper notification. Defective components must be returned to the dealer for replacement. The buyer is responsible for transportation costs, and the cost of delivering replacement parts will not exceed the original delivery cost of the sauna.
