Kiki Core Outdoor Sauna — Compact Thermowood Garden Sauna
A compact Thermowood garden sauna with a sheltered architectural character, bronzed glazing and room for up to three people.
A Quiet Sauna Ritual, Designed for Smaller Gardens
The Kiki Core Outdoor Sauna brings the atmosphere of a dedicated Nordic hot room into a footprint that works comfortably within smaller gardens, terraces and private recovery spaces.
Its darker external detailing gives the structure a calm, architectural presence, while the warm Thermowood interior and bronzed glazing create a more intimate experience than a fully panoramic sauna. It is designed for regular solo sessions, couples and occasional shared use without asking the garden to accommodate a larger retreat building.
The Kiki Core can be supplied as a precision flat-pack structure or taken through a wider KeiCo project route covering the heater, base, timber protection, installation, lighting and aftercare.

Compact, Sheltered and Purposeful
The Kiki Core is intentionally more enclosed than a full-glass cube sauna. The glazed door and side window admit natural light and maintain a connection with the garden, but the solid Thermowood envelope keeps the room visually calm and protected.
Inside, the two-level Thermo-Aspen bench arrangement allows the user to sit at different heights within the heat. The approximately 1.5m internal depth makes the sauna particularly well suited to personal routines and shared sessions for two, while its nominal three-person capacity provides useful flexibility when required.
Black-painted trims and selected internal details introduce contrast against the Thermowood. Bronzed glazing softens the view into the cabin; perceived privacy will vary according to the balance of internal and external light.
Thermowood for Outdoor Stability
The 40mm walls and roof are formed in heat-treated timber selected for improved dimensional stability and reduced moisture movement compared with untreated softwood. The 28mm Thermowood floor completes the main cabin envelope.
Thermowood still requires considered exterior protection and periodic care. A clear or coloured treatment can be selected to preserve the timber tone or connect the sauna with surrounding fencing, paving and architecture. Any product used inside the hot room must be specifically suitable for sauna temperatures.
Configure the Heat and Finish
The cabin is supplied without a heater unless the chosen package expressly includes one. The Kiki Core is normally paired with an approved compact electric sauna heater, with the final model confirmed against the 4.1m³ internal volume, glazing allowance, controller preference and electrical supply.
Available project choices may include:
- Approved electric heater and control package
- Manual or connected control where available
- Self-installation or professional KeiCo assembly
- Existing hardstanding, ground-screw or prepared base route
- Clear or coloured exterior timber protection
- Sauna-appropriate internal protection
- Ambient LED lighting and selected accessories
- KeiCo Care or Signature Care
Every displayed option remains subject to compatibility with the exact cabin specification. Electrical connection must be completed by a qualified electrician.
Build Your KeiCo Wellness Space
The product price is the starting point for the cabin structure. The configurator allows the surrounding project to be shaped around how you intend to use it—from a straightforward supply-only sauna to a coordinated garden installation with base preparation, heater specification, treatment, lighting and cold-plunge integration.
KeiCo reviews the complete configuration before fulfilment so that the heater, site preparation and installation route remain aligned with the cabin supplied.

Dimensions and Site Preparation
The external footprint is approximately 1,496mm wide × 2,019mm deep, with an overall height of approximately 2,161mm. The internal room measures approximately 1,410 × 1,500 × 1,930mm.
A firm, level, load-bearing and well-drained base is required. Before permanent works begin, confirm the source-specific drawing, final bearer positions, door orientation, electrical route, access width, unloading space and maintenance clearances. The sauna should not be installed directly onto grass, loose soil or an uneven surface.
Lead Time, Delivery and Installation
The Kiki Core is made to order, with a typical lead time of approximately 6–8 weeks before delivery or installation, subject to the confirmed specification and production schedule.
Delivery is normally made in flat-pack palletised form. The final courier route, unloading responsibility and installation date are confirmed for the individual site.
The sauna may be supplied through an approved European partner within KeiCo’s Nordic manufacturing network. KeiCo remains responsible for the customer-facing specification, project communication and agreed after-sales route. Final base work must follow the technical drawing issued for the allocated production source.
A Coordinated KeiCo Project
KeiCo can support product specification, access planning, base preparation, heater selection, electrical coordination, professional installation, timber protection, lighting, recovery integration and ongoing care. Regulated electrical work is completed or coordinated with suitably qualified trades.
Warranty and Continued Care
The applicable KeiCo warranty is confirmed in the final order documentation and remains subject to correct installation, approved electrical work, prompt exterior treatment, intended use and documented maintenance.
KeiCo Care provides a structured route for maintenance guidance and continued support, with Signature Care available where a more managed ownership pathway is preferred.

FAQ's
How many people can use the Kiki Core sauna?
The Kiki Core is most comfortable for one or two people and has a nominal maximum capacity of three. Its approximately 1.5m internal depth makes it particularly well suited to personal routines and couples.
What heater is suitable for the Kiki Core?
The Kiki Core has an internal volume of approximately 4.1m³ and is normally paired with an approved compact electric sauna heater in the 6kW class. The final heater and controller must be confirmed against the glazing allowance, available electrical supply and exact cabin specification.
What base does the Kiki Core need?
It requires a firm, level, well-drained and load-bearing base. Common routes include a correctly designed concrete slab, reinforced paving or a suitable structural deck. Final dimensions and bearer positions must follow the technical drawing issued for the allocated production source.
Does the Thermowood exterior need treatment?
Yes. Thermowood offers improved stability, but an appropriate exterior protection system is still required to maintain appearance and support the applicable warranty conditions. The finish should be inspected and maintained according to exposure and the selected treatment.
Can KeiCo deliver and install the Kiki Core?
Yes. The sauna can be supplied as a palletised flat-pack kit for competent self-assembly, or KeiCo can quote for professional installation. Base preparation, heater specification, electrical coordination, timber protection, lighting and aftercare can also be included within the agreed project scope.
