The KeiCo ICON 385 Deluxe Thermowood Outdoor Sauna Cube with Change Room
Arrive. Change. Heat. Reset.
The KC ICON 385 Deluxe is designed around the complete sauna ritual—not only the time spent in the heat.
Step beneath the covered canopy. Leave the day behind in a dedicated changing room. Move into the warmth of a spacious 4–6 person sauna. Then return outside to cool down, breathe, and begin again.
Its curved Thermowood form brings together three distinct stages of the experience within one architectural structure, creating a garden retreat that feels considered from the moment you arrive.
Whether used for quiet morning sessions, post-training recovery, evenings with family, or shared weekends with friends, the ICON 385 gives heat and stillness a permanent place within everyday life.
Three Stages. One Complete Retreat.
The ICON 385 is arranged to create a natural progression through the sauna experience.
Covered Porch
A sheltered entrance with integrated bench seating, providing a place to pause, cool down between rounds, or sit beneath the open sky after a session.
Dedicated Changing Room
A separate arrival and transition area for robes, towels, footwear, and personal belongings.
Rather than stepping directly from the garden into the heat, the changing room gives the experience privacy, order, and a stronger sense of ritual.
4–6 Person Sauna Room
A spacious heated room with ergonomic Aspen benches and backrests, designed for solo recovery, couples, families, and shared sessions.
The curved internal profile supports natural heat movement, while the Thermowood surroundings create a warm, grounded atmosphere.
Together, these spaces transform the ICON 385 from a standalone sauna into a complete outdoor retreat.
The KeiCo Difference Begins Around the Product
At KeiCo, we do not see installation day as the beginning and end of the relationship.
We see the sauna as the centre of a wider environment—one that may require a base beneath it, the electrical supply, the finish, surrounding landscaping, cold therapy, outdoor showering, lighting, and the years of ownership that follow.
Some customers choose flat-pack delivery to embrace their own keen DIY journey.
Others ask KeiCo to manage the wider process from site preparation through to final handover.
Depending on your project, our team can assist with:
- Product and heater specification
- Site layout and positioning
- Delivery and access planning
- Base preparation
- Professional sauna installation
- Electrical requirement coordination
- Exterior and interior timber protection
- Roof and weather-management upgrades
- Cold plunge and outdoor shower integration
- Sauna accessories and ambient lighting
- Annual servicing and longer-term KeiCo Care
Where regulated or specialist works are required, these are completed or coordinated with suitably qualified trades.
The result is not simply an installed product.
It is a finished KeiCo wellness space, shaped around your home and the way you want to live.
Built for Shared Rituals
The ICON 385 is particularly well suited to customers who want more than a compact two-person sauna.
Its larger format creates space for:
- Morning sauna and breathwork routines
- Couples and family sessions
- Post-training recovery
- Evening wind-down rituals
- Hosting friends or guests
- Sauna and cold plunge pairings
- Holiday-let and retreat wellness experiences
- Private residential spa gardens
The dedicated changing room also makes the ICON 385 more practical for regular shared use, especially through colder or wetter months.
For hospitality or commercial environments, final specification and suitability should be assessed against expected usage, servicing, and operational requirements.
Crafted in 42mm Thermo-Spruce
The ICON 385 is formed from 42mm Thermo-Spruce staves, creating its distinctive curved shell.
Thermal modification improves the timber’s dimensional stability and resistance to moisture and decay when compared with untreated Spruce, making it well suited to year-round outdoor use.
The warmer, richer colour of Thermo-Spruce gives the structure a natural architectural presence, while stainless-steel bands and fittings secure the curved form.
The exterior can be protected and visually tailored through clear or coloured treatment options, allowing the sauna to connect with the home, fencing, paving, or wider landscape design.
Light, Privacy, and a View Beyond the Sauna
Glazing brings natural light into the ICON 385 while maintaining the enclosure required for a calm sauna environment.
For customers with a garden view or more scenic setting, an optional half-moon rear glass window can be added to create a stronger connection between the heat and the landscape beyond.
The rear-glass upgrade changes the feel of the room—bringing daylight deeper into the sauna and creating a focal point from the bench.
Perceived privacy will vary according to internal and external lighting conditions.
Choose Your Heat Experience
The ICON 385 can be configured with either electric or wood-fired heat.
Electric Heat
Choose from compatible Harvia and HUUM heater options for straightforward operation, controlled heat, and regular home use.
Depending on the chosen package, electric options may include:
- Manual control
- External control systems
- WiFi-enabled operation
- Different stone capacities and visual styles
All electric sauna heaters must be connected by a certified electrician. Final power requirements depend on the selected heater and available electrical supply.
Wood-Fired Heat
A wood-fired configuration creates a more traditional and elemental sauna ritual centred around flame, fuel, and gradual heat.
Wood-fired systems require suitable flue components, shielding, clearances, and safe positioning. The final package should be reviewed against the installation site before works begin.
Our team can help identify the most appropriate system based on room volume, available power, preferred control method, and the kind of sauna experience you want to create.
Dry Heat or Traditional Steam-Style Sauna
The ICON 385 can be enjoyed as a dry sauna or with bursts of increased humidity.
Allow the heater and stones to radiate naturally for a steady dry heat experience.
For a more traditional sauna sensation, ladle water over suitable heated stones to create löyly—a short, more intense wave of heat and humidity.
This flexibility allows each session to be shaped around the user, the moment, and the desired ritual.
Build Your ICON 385
The structure provides the foundation. The final environment is created through the choices around it.
Depending on the live configurator and selected specification, available options may include:
- Harvia or HUUM electric heater packages
- Wood-fired heater configuration
- Professional KeiCo installation
- Base preparation
- Exterior timber treatment
- Interior timber protection
- Half-moon rear-glass upgrade
- Under-bench LED lighting
- Roof-shingle colour choice
- Weather-management additions
- Sauna accessories
- Cold plunge pairing
- KeiCo Care or Signature Care
This allows you to choose between a straightforward sauna supply and a much more complete garden wellness transformation.

Complete the Ritual
The ICON 385 works beautifully as a standalone sauna, but its changing room and covered porch make it an ideal foundation for a wider outdoor spa environment.
Consider pairing it with:
Cold Plunge
Create a repeatable contrast sequence by moving between heat and controlled cold exposure.
Outdoor Shower
Add a practical rinse and cooldown point between sauna rounds.
Ambient Lighting
Extend the use of the retreat into the evening and create a softer transition between the sauna and garden.
Timber Protection
Protect the appearance and condition of both internal and external surfaces through suitable sauna-specific treatments.
KeiCo Care
Support the structure beyond installation through scheduled servicing and ongoing ownership guidance.
Together, these elements create the complete sequence:
Arrive → Change → Heat → Cool → Recover → Repeat
Health & Recovery Benefits
Regular sauna use is commonly associated with:
- Supporting relaxation and stress reduction
- Helping the body unwind after training or demanding days
- Encouraging a more consistent recovery routine
- Supporting circulation through heat exposure
- Creating space for breathwork, stillness, and mental reset
- Building a structured morning, evening, or post-exercise ritual
Many customers combine sauna use with cold exposure, movement, and rest as part of a wider approach to personal wellbeing.
Sauna use should be adapted to the individual.
A Garden Retreat With Its Own Rhythm
The KC ICON 385 Deluxe is for those who want the experience to begin before the sauna door opens.
A place to arrive.
A room to prepare.
A space to share the heat.
A porch to cool down beneath the sky.
It gives the garden a new purpose and the day a new point of return.
KeiCo can supply the structure—or help build the complete environment around it.
