How It Works – From First Consultation to Your Hetki Cabin Ready to Use (UK)

As the authorised UK retailer for Hetki, we guide you through every stage of the process — from initial consultation and customisation through to delivery, installation, and final handover. Our role is to ensure your Hetki Cabin or sauna is delivered, installed, and ready for use with absolute clarity at every step.

Step 1: Initial Consultation

• Your journey begins with a consultation with our UK Hetki team.

We discuss:

• Whether you are purchasing a Hetki Cabin, sauna, or complete outdoor wellness space
• Residential or commercial use (home, spa, hotel, retreat or hospitality venue)
• Placement, access, and site conditions
• Design preferences, finishes, and optional upgrades
• You are welcome to share photos or videos of your proposed location at this stage. This allows us to assess access, lifting requirements, and suitability early, avoiding delays later in the process.

Step 2: Design, Specification & Quotation

• Once we understand your requirements, we will finalise the specification of your Hetki Cabin.

This includes:

• Exterior colour, glazing and door options
• Interior features, including lighting, radiator and layout
• Electrical configuration (pre-wired, plug-and-play model)
• Commercial considerations were applicable
  

We then provide:

• A clear quotation
• Dimensional drawings and floor plans
• Foundation and site preparation guidance
• This information enables you to prepare your site and engage any contractors or electricians in advance.

Step 3: Site Access & Delivery Planning

• Before confirming delivery, we plan logistics carefully to ensure a smooth installation.

We will:

• Review site photos and access routes
• Confirm that your location is accessible by a heavy goods vehicle and crane
• Determine whether a truck-mounted crane or external lifting equipment is required
• In more complex locations, specialist lifting solutions may be needed. These are always discussed and agreed upon in advance.
• If decking, paving, curbstones or landscaping is planned around the cabin, we recommend that these works be completed after the cabin has been installed.

Step 4: Ground & Foundation Preparation (Customer Responsibility)

• A correctly prepared foundation is essential for the performance, safety and longevity of your Hetki Cabin.

The foundation must:

• Be even, strong and stable
• Support up to 2,000 kg, including occupants
• Suit the soil and ground conditions of your site
  

Suitable foundation options include:

• Reinforced concrete slab or pad
• Strong patio or paving on a compacted base
• Crushed gravel with structural support

The base should:

• Extend beyond the external dimensions of the cabin
• Provide an air gap of approx 15–20 cm beneath the structure
• Prevent timber from contacting ground moisture
• We strongly recommend consulting a qualified builder, architect or structural engineer to confirm suitability. Foundation drawings and guidance are supplied as part of the purchase.

Step 5: Delivery of Your Pre-Assembled Hetki Cabin

• Your Hetki Cabin is delivered to the site as a fully pre-assembled structure, not a flat-pack or modular kit.

This approach offers significant benefits:

• Faster installation
• Minimal disruption on site
• Consistent Finnish build quality
• Reduced risk compared to on-site construction
• Delivery is typically carried out by truck, with lifting handled by a crane integrated into the vehicle or an external crane where required.

Step 6: Installation by Our UK Installation Team

On delivery day, our experienced UK installation team will:

• Lift and position the cabin onto its prepared foundation
• Level and secure the structure
• Carry out final checks and visual inspection
• This ensures the cabin is correctly installed and ready for final connection.

Step 7: Electrical Supply & Connection (Customer Responsibility)

• All Hetki Cabins are delivered with internal electrical wiring completed. However, the external electrical supply is the responsibility of the customer.

You must:

• Provide a suitable power supply to the cabin location
• Engage a qualified, registered electrician
• Ensure compliance with all UK electrical regulations and certification requirements
• ⚠ Our installation team does not carry out external electrical works, mains connections, or certification. We strongly recommend arranging your electrician well in advance so that power is ready for connection immediately after installation.

Step 8: Drainage & Final Site Considerations

• Hetki Cabins include integrated guttering and floor drainage options.
• Drain locations are marked in the supplied drawings
• Any drainage system must allow water to safely disperse away from the structure
• Adequate clearance should be left around the cabin for airflow and durability
• For best long-term performance, avoid placing the cabin directly next to plants, trees or bushes.

Step 9: Final Handover & Ready to Use

Once:

• The cabin is installed.
• The electrical connection has been completed by your electrician
• Your Hetki Cabin is fully operational and ready to use.

We provide:

• Product documentation
• Maintenance and care guidance
• Ongoing support as your UK Hetki retailer

Electrical Supply & Installation Guidelines: Hetki Cabin

Project: Insulated Living & Workspace (Non-Sauna)

To ensure the safety and longevity of your Hetki Cabin, please provide this document to your qualified electrician. All installations must comply with BS 7671 (IET Wiring Regulations).

⚠️ Mandatory Advisory: Electricians' Discretion 

Every property is unique. Factors such as the distance from your main consumer unit, the method of cable burial, existing household electrical demand, and local earthing conditions (TT vs. TN-S) will dictate the final technical specifications.

The data provided below are estimates for preliminary planning. You must always defer to the formal calculations and professional judgment of your certified electrician regarding cable sizing, circuit protection, and earthing methods.

1. Internal Specification (The Load)

The Hetki Cabin is typically equipped with a pre-installed internal "looming" kit designed for standard office or guest room use:

• Heating: Integrated Electric Radiator (Climate Control).
• Lighting: Internal LED strip lighting and/or ceiling fixtures.
• Power: Standard internal 13A sockets for laptops and small appliances.

2. Electrical Supply Requirements

The cabin requires a 230V Single-Phase (UK) supply.

• Standard Load: Most Hetki Cabins operate efficiently on a dedicated 16 Amp supply.
• Heavy-Use Load: If you intend to use high-draw appliances (e.g., kettles, heaters, or high-end servers), your electrician may specify a 32 Amp supply.
• Calculation Reference: Watts / Volts = Amps

3. Site-Specific Variables (Why your Electrician decides)

Your electrician must perform a site survey to determine the following:

• Voltage Drop: If the cabin is a significant distance from the house (e.g., 30m+), a much larger cable diameter than the standard minimum will be required to ensure the radiator and electronics function correctly.
• Total Home Load: Your electrician must verify that your property’s main incoming fuse can support the cabin, along with existing high-load items such as EV chargers or electric showers.
• Earthing System: Exporting a PME (TN-C-S) earth to a garden building requires specific safety checks. Your electrician will decide if a separate Earth Rod (TT System) is required.

4. Mandatory Technical Standards

• SWA Cabling: The supply from the house to the cabin must be Steel Wire Armoured (SWA) cable, buried at the correct depth and marked with warning tape.
• RCD Protection: The circuit must be protected by a 30mA RCD/RCBO at the source.
• Isolation: A local double-pole isolator switch or a dedicated mini-consumer unit must be installed at the cabin for emergency shut-off and maintenance.
• IP Ratings: Any external connection points or outdoor lighting must be rated IP65 or higher.

5. Regulatory Compliance & Liability

All electrical work must be tested and commissioned by a registered professional. A Building Regulations Compliance Certificate (Part P) should be issued upon completion.

Disclaimer: Our installation team are specialists in timber assembly and structural finishing. We are not certified electrical contractors. We accept no liability for issues arising from inadequate power supply, incorrect component selection by third parties, or failure to account for site-specific voltage drop.

The Hetki Cabin is delivered to the UK as a fully pre-assembled, plug-and-play unit, ensuring a fast, efficient installation with minimal disruption. Unlike flat-pack garden rooms or on-site builds, this approach guarantees superior build quality, quicker setup, and long-term performance.

Installation is handled by the Balance Recovery installation team, with clear responsibilities outlined below to ensure a smooth and compliant process.

1. Pre-Assembled & Plug-and-Play Benefits

Your Hetki Cabin arrives fully assembled, with internal electrics pre-installed at the factory. This provides several key advantages for UK customers:

• No on-site construction or structural assembly
• Reduced installation time and labour costs
• Consistent Finnish build quality
• A faster route to use and enjoyment

The plug-and-play model means all internal systems are ready for connection; however, the final electrical connection must be completed by a qualified electrician.

2. Access, Delivery & Lifting Requirements

Before delivery, we will discuss and confirm the exact placement location of your cabin. Customers are encouraged to send photos of the site in advance to their Hetki retailer or Balance Recovery to ensure a safe and efficient delivery.

• The cabin is typically delivered by a heavy goods vehicle
• Your site must be accessible by a truck and crane
• Lifting is typically performed using a crane mounted on the delivery truck

In more complex locations or longer lifting distances, an external crane may be required. In rare, highly challenging locations, specialist lifting methods may be necessary. If your cabin will be surrounded by decking, paving, or kerbstones, they should be installed only after the cabin has been positioned.

Ensuring clear access significantly reduces delivery time, cost, and risk.

3. Ground & Foundation Requirements

A correct foundation is essential for the performance, safety, and longevity of your Hetki Cabin.

The foundation must be:

• Even strong and stable
• Capable of supporting up to 2,000 kg, including occupants
• Designed according to local soil and ground conditions

We strongly recommend that the site be assessed by a qualified architect or building engineer before installation. Dimensional drawings, floor plans, and foundation guidance will be supplied with your purchase.

4. Recommended Foundation Types

Suitable bases include:

• Concrete pad or slab
• Reinforced patio or hardstanding
• Paver blocks or garden slabs on a solid base
• Crushed gravel base with structural support

If installed on a patio or deck, it must be designed to support the cabin's full load.

5. Key Foundation Guidelines

• The base should extend beyond the external dimensions of the cabin.
• The cabin must not be installed directly on lawn, loose slabs, rubble, gravel, or bare ground.
• A 15–20 cm air gap beneath the cabin is required for ventilation and moisture control.
  Reinforced pillar foundations are recommended at all four corners and beneath the door wall.
• Bitumen roofing felt must be placed between the foundations and timber to prevent moisture absorption.
• In colder conditions, we recommend 5–10 cm of ground frost insulation beneath the base to prevent frost movement and thermal bridging.

6. Drainage & Exterior Clearance

Hetki Cabins include:

• Integrated water guttering
• A floor drain that can be connected to a soakaway or drainage system
• The drain location is clearly marked in the supplied dimensional drawings. Please ensure that all water can safely drain away from the cabin.

For durability and ventilation:

• Do not place the cabin too close to trees, bushes, or plants
• Leave adequate space around the structure to allow airflow and drying
  

7. Electrical Supply – Customer Responsibility

While the cabin arrives internally wired, the external electrical supply is the responsibility of the customer.

This includes:

• Providing a suitable power supply to the cabin location
• Ensuring compliance with UK electrical regulations
• Engaging a qualified, registered electrician to complete the final connection and certification

⚠ Balance Recovery does not carry out external electrical work, mains connections, or certification. We strongly recommend consulting your electrician early to ensure everything is ready before installation day.

8. Professional Installation by Balance Recovery

On installation day, the Balance Recovery team will:

• Position the cabin using appropriate lifting equipment
• Level and secure it onto the prepared foundation
• Complete final checks and handover

Electrical connection and certification must be completed separately by your appointed electrician.

9. Why This Matters for UK Customers

This delivery and installation process ensures:

• Compliance with UK building and electrical standards
• Faster installation compared to on-site builds
• Reduced risk and long-term structural reliability
• A premium, stress-free ownership experience

If you require guidance on site preparation, access planning, or foundation design, our team is happy to assist before delivery.

The Customer should be aware and accept that apart from weathering and altering over time, the same colour shade may look somewhat different on different wooden materials and parts of the Product (e.g. walls, frames and boards, ceiling panels, floor, benches).

7. Changes to Warranty Terms and Products

The Supplier reserves the right, at its sole discretion, to update, change or replace any part of these Warranty Terms without notice by posting updates and changes on its website (https://www.hetkisauna.com/).

8. Validity

These Warranty Terms apply from 1.1.2021 until further notice.

9. Governing Law

Any dispute relating to these Warranty Terms and any separate agreements between the Supplier and the Customer is primarily addressed through negotiation.

These Warranty Terms and any separate agreements are governed and shall be construed in accordance with the laws of Finland.

The Parties submit all their disputes to the exclusive jurisdiction of the District Court of Helsinki, Finland. The seat of arbitration shall be in Helsinki, Finland, and the language of the arbitration shall be Finnish.
