Installation & Requirements

Room Preparation: Requires a level, solid floor capable of supporting 450kg (concrete, reinforced timber joists, or solid flooring). Allow minimum 150mm clearance from walls on all sides for proper air circulation and heat dissipation. Minimum room dimensions: 175cm × 165cm including clearance allowances. 

Ventilation: Adequate ventilation is essential for safe operation. The room must have either natural ventilation (window or air vent) or mechanical extraction. Fresh air intake and exhaust are critical for maintaining proper oxygen levels and removing moisture during use.

Ceiling Height: Minimum 230cm ceiling height required to accommodate the 221cm sauna height plus clearance.

Electrical: The 6kW heater requires a dedicated 32A circuit installed by a qualified electrician (installation not included). Heater must be hardwired – no plug connection.

Assembly: Designed for straightforward DIY assembly. Most customers complete installation in a weekend with basic tools. Comprehensive instructions included.

Delivery: Specialist delivery required. Ships in a single DIY box (H:78cm, L:209cm, W:111cm). Ensure delivery access to your installation room.

Why Thermally Modified Wood?

Thermal modification isn't just a treatment—it's a complete transformation. The wood is heated to 200°C, permanently altering its cellular structure for exceptional durability. The naturally darker, richer colour creates a sophisticated aesthetic that complements contemporary interiors beautifully, whilst the enhanced stability ensures your sauna maintains its shape and performance for decades.

Perfect For

• Couples seeking a private wellness retreat at home
• Homeowners with spare rooms or basement spaces
• First-time sauna buyers
• Year-round wellness enthusiasts
• Property developers adding luxury amenities to residential or commercial spaces
