KC ISLA Panoramic 70mm Garden Sauna + Shower Terrace | In Stock
Panoramic Heat and Outdoor Recovery, Already in Motion
The KC ISLA Ready Panoramic Garden Sauna combines a substantial 70mm Nordic Spruce sauna with an adjoining outdoor terrace, creating a connected environment for heat, fresh air and cold-water recovery.
Its full-height panoramic glass frontage brings natural light into the sauna and opens the interior towards the surrounding garden. Inside, dual Aspen benches provide a calm heat environment for approximately 2–4 people.
Outside, the integrated terrace creates a dedicated place to cool down, add an outdoor shower or incorporate a compatible compact cold plunge, subject to the final equipment, base and service requirements.
This pre-selected ISLA forms part of an incoming KeiCo Ready allocation, providing a shorter route to ownership than beginning a new made-to-order production cycle.
The sauna is already in motion. The finished wellness environment remains yours to shape.

Panoramic by Design
The full-height glass frontage is central to the ISLA experience.
It allows daylight to travel through the sauna and creates a stronger visual connection between the internal heat room and the garden beyond.
Rather than feeling enclosed, the room remains bright, open and architectural while retaining the warmth and character of its substantial Nordic Spruce construction.
An internal glass door separates the heated sauna room from the adjoining terrace, creating a clear transition between heat and outdoor recovery.
Perceived privacy changes according to internal and external lighting conditions, so the final position should still account for neighbouring properties and surrounding sightlines.
A Terrace Built Into the Ritual
The adjoining terrace forms part of the ISLA structure.
It provides a purposeful transition area that may be used for:
- Cooling down between sauna rounds
- Breathwork and quiet recovery
- Robe and towel storage during use
- An optional outdoor shower
- A compatible compact cold plunge
- A small seat or recovery area
The outdoor shower itself is not included as standard and must be selected separately.
A shower installation requires a suitable water supply, frost protection, plumbing route and drainage arrangement. These should be considered before the base and final sauna position are agreed.
Where a cold plunge is added, its dimensions, filled weight, filtration, chiller connections, drainage and maintenance access must also be reviewed.
Built in 70mm Nordic Spruce
The KC ISLA uses substantial 70mm Nordic Spruce walls to create a strong and characterful outdoor sauna environment.
Nordic Spruce provides:
- A pale, natural timber appearance
- Traditional Scandinavian character
- A warm contrast against the panoramic glazing
- A suitable surface for clear or coloured exterior finishes
- A substantial structural base for regular outdoor use
As an outdoor timber structure, the ISLA requires appropriate exterior protection and continued maintenance.
The final finish can be tailored around the property through clear protection or selected architectural colour treatments shown within the live configurator.
Configure Your ISLA
The displayed price includes the pre-selected inbound core structure.
The OPTIS configurator then allows the ISLA to be completed around your preferred heat experience, appearance and level of KeiCo support.
1. Choose Your Heat
Select a compatible:
- Harvia electric heater
- HUUM electric heater
- Manual or external control system
- WiFi-enabled control package where compatible
- Wood-fired heater and flue package
- Supply-only option without a heater
The correct heater must be matched to the internal sauna volume, panoramic glass area, available electrical supply, roof specification and intended frequency of use.
All electric sauna heaters require installation and connection by a qualified electrician.
Wood-fired systems require the correct stove, chimney, heat protection and safety clearances.
2. Choose Your Project Route
Select flat-pack delivery for assembly by your own competent team, or choose professional installation through KeiCo.
3. Prepare and Protect
Choose the appropriate:
- Base or foundation route
- Exterior timber treatment
- Internal timber protection
- 100mm insulated roof upgrade
- Guttering or weather-management additions where available
4. Complete the Ritual
Add the elements that support everyday use:
- Outdoor shower
- Ambient sauna lighting
- Bluetooth audio
- Timber headrests
- Bucket and ladle
- Thermometer and timer
- Towels and aromatherapy options
- Cold plunge
- KeiCo Care or Signature Care
Optional Insulated Roof Upgrade
A 100mm insulated roof-panel upgrade is available for customers wanting to enhance the roof build-up for more regular year-round use.
It may be particularly relevant where:
- The sauna will be used frequently throughout winter
- The property is located in a more exposed setting
- Improved heat retention is a project priority
- The structure will support holiday-let or higher-frequency use
The final heater and roof specifications should be considered together so the complete heat environment is appropriate for the intended use.

FAQ's
Do I need planning permission for an outdoor sauna in the UK?
Many domestic garden saunas in England can be installed under permitted development rights because sauna cabins are treated as garden outbuildings. However, every relevant limit and condition must still be satisfied. Permission may be required depending on the sauna’s position, proximity to boundaries, total garden coverage, property type and whether the site is listed or located within designated land. Different rules may also apply in Scotland, Wales and Northern Ireland, or where the sauna is intended for commercial or holiday-let use. The optional shower, electrical supply and any wood-fired chimney should also be considered as part of the complete proposal. We recommend confirming the intended installation address with us prior to starting foundation, plumbing or electrical works.
What size sauna heater does a panoramic glass outdoor sauna need?
The correct heater must be calculated from the sauna’s effective heated-room volume, rather than from its external dimensions alone. Harvia’s general guidance allows approximately 1kW of heater output for every cubic metre of sauna volume. It also recommends increasing the calculation for glass and other non-insulated surfaces: every square metre of glass adds approximately the same heater demand as an additional 1.2m³ of room volume. Because the KC ISLA has substantial panoramic glazing, the glass allowance is particularly important. The final heater package should therefore be confirmed against: Internal heated-room dimensions Total glass area Roof-insulation specification Electric or wood-fired heat path Available electrical supply Intended frequency of use KeiCo can match the appropriate Harvia or HUUM package to the completed ISLA configuration.
Can I add an outdoor shower or cold plunge to the KC ISLA sauna terrace?
Yes. The adjoining ISLA terrace is designed to create a practical transition between the sauna, fresh air and cold-water recovery. An outdoor shower can be added subject to a suitable water supply, isolation, frost protection, compliant backflow protection and an agreed drainage route. UK water-fitting guidance requires showers to have appropriate protection against contamination of the drinking-water supply, with the final arrangement determined by the installation and local requirements. A compatible cold plunge may also be incorporated, but its: External dimensions Filled operating weight Access requirements Filtration or chiller connections Drainage and maintenance space must be reviewed before the base and layout are finalised. Wastewater must be managed so that it does not create pollution, flooding or nuisance. Shower, plumbing and drainage works are quoted separately unless expressly included within the agreed KeiCo project scope.
What base does the KC ISLA outdoor sauna need?
The KC ISLA requires a solid, level, well-drained and load-bearing base supporting the complete structure and terrace evenly. The sauna weighs approximately 950kg before the heater, users, accessories and any terrace-based recovery equipment are added. Suitable foundation routes may include: A correctly prepared concrete slab An engineered paving system over a compacted structural sub-base A suitable ground-screw foundation A reinforced deck or framed platform designed for the completed load An existing hardstanding confirmed as structurally suitable The base should not be laid directly onto grass, loose soil or an uneven surface. If a cold plunge is positioned on or beside the terrace, its full water-filled weight must be included within the structural assessment. Shower drainage, cable routes and future servicing access should also be planned before the foundation is installed. KeiCo can review the proposed site and provide a separate base-preparation quotation where required.
How much does an outdoor sauna cost to run in the UK?
The simplest way to estimate the running cost of an electric sauna is: Heater output in kW × operating time in hours × your electricity unit rate Using the current Great Britain average default-tariff electricity rate of approximately 26.11p per kWh for July to September 2026: An 8kW heater drawing full power for one hour would cost approximately £2.09 A 9kW heater drawing full power for one hour would cost approximately £2.35 These are full-power examples rather than guaranteed session costs. In normal operation, the heater may cycle on and off after the desired temperature is reached. Actual consumption will depend on: Selected heater output Outdoor temperature Warm-up time Panoramic glass area Roof-insulation choice Door opening Session duration Your individual electricity tariff The daily standing charge is not included because it would normally be payable regardless of sauna use.
