The Barrel Sauna (4m) Technical Specification

Buying Guide Barrel Sauna (4m)

Model: The Grand Barrel | 4m Ergonomic Social Suite

1. Place Your Order

• Choose the Barrel Sauna (4m), our most spacious classic-profile outdoor model.
• Standard configuration includes the Harvia Clindro, 6.8kW heater, NEW-Style ergonomic Alder benches, and colour-changing LED lighting.
• Complete your order online to secure your 2026 delivery slot.
• Property Check: Given the 4000mm length, please provide a video of your garden access. Navigating a 4m structure requires clear linear space. Delivery is kerbside only.

2. Order Processing & Manufacturing

• Your Grand Barrel is manufactured with 42mm side timber for elite thermal circularity. Your order includes:
• Spacious Barrel Body: 4000mm (L) x 2150mm (W) x 2050mm (H).
• Thermal Engine: Harvia Clindro, 6.8kW Electric Heater (Includes stones).
• The "Vista" Entrance: Panoramic 8mm Bronze Safety Glass door.
• Luxury Ergonomics: S-curved Alder terrace benches and floor grates.
• Atmosphere: Integrated colour-changing LED lighting system.
• Protection: Katepal shingle roof (Black, Brown, Red, or Green).

3. Delivery Organisation – FREE Kerbside Delivery

• The Logistics: Your sauna is delivered as a high-precision palletised kit. The driver will unload the pallets at the nearest safe kerbside point.
• Handling the Length: With 4m timber lengths, ensure you have adequate space on your driveway or kerbside to store the components before moving them to the garden.
• Notification: Our logistics team will coordinate your delivery window via SMS/Email.

4. Pre-Installation Preparation

• Foundation: A perfectly level, solid base is essential to prevent the barrel from "rolling" or the staves from shifting. Concrete pads or heavy-duty timber sleepers are recommended.
• Electrical Preparation: The Harvia Clindro, 6.8kW heater requires professional infrastructure.
• Requirement: A dedicated 32-Amp single-phase supply (hardwired).
• Action: Consult your electrician to ensure a dedicated circuit is ready at the site location.

5. Delivery Day & Inspection

• Your Responsibility: Moving the components from the kerbside to the garden.
• The Team: We recommend 3 capable adults to handle the 4m staves and the large panoramic glass door.
• Inspection: Check all 42mm staves and the 8mm glass for transit marks. Report any damage within 24 hours.

6. Installation Options

• Professional Installation:  Price Available on Request.
• Recommended for the 4m model. Our team ensures the tension bands are perfectly calibrated and the roof shingles are expertly sealed.
• Includes a 2-year structural warranty.
• Self-Assembly: A classic "jigsaw" build for confident DIYers. The interlocking staves must be tightly seated before the steel bands are tensioned. Includes a 1-year warranty.

7. Finishing Touches & Safety Check

• Circadian Lighting: Use the colour-changing LED remote to set the mood—amber for relaxation or blue for a fresh morning session.
• Timber Care: The "Natural Effect" finish requires a UV-protective stain application within 14 days to maintain the Spruce wood’s integrity.
• The "First Heat": Season the 4m cabin by running the 6.8kW heater for 60 minutes. This tightens the timber joints and cures the heater elements.

8. Enjoy Your Sauna & Ongoing Support

• The Experience: Expansive internal volume with ergonomic support. Ideal for 4–6 people.
• Maintenance: Ensure the built-in drain tap is clear. Tighten the stainless steel exterior bands slightly after the first month as the wood settles.
• Support: Our 2026 team is here for technical support and Harvia accessories.
• Note: 32A hardwiring is mandatory. Non-refundable once production commences.

Electrical Supply Specification Barrel Sauna (4m)

Model: The Grand Barrel | 6.0kW Harvia Harvia Clindro Series

⚠️ Mandatory Electrical Disclaimer & Responsibility

The installation of a 6.8kW sauna heater is a significant electrical undertaking. It is the customer’s sole responsibility to consult and engage a qualified, Part P registered electrician to design, install, and certify the electrical supply.

1. Core Electrical Requirements

The Barrel Sauna (4m) utilises the Harvia Harvia Clindro traditional heater. To manage the 42mm spruce thermal mass and the expanded 4m length, the following supply is required:

• Heater Output: 6.0 kW
• Power Supply: Single Phase 230V / 50Hz
• Amperage Draw: Approximately 26.1 Amps
• Supply Type: Dedicated 32-Amp Circuit (Hardwired).

2. Customer’s Responsibility: The Electrician’s Brief

You must provide the following information to your electrician before the sauna arrives:

• Dedicated Breaker: The sauna must be on its own dedicated radial circuit. Your electrician should install a 32A Type B MCB (or RCBO) at the consumer unit.
• RCD Protection: In accordance with Section 703 for saunas and steam rooms, the circuit must be protected by a 30mA Residual Current Device (RCD).
• Local Isolation: A waterproof (IP66-rated) double-pole rotary isolator switch must be installed externally, within sight of the sauna, for safety and maintenance.

3. Cable Specification

Your electrician will determine the exact cable size based on the distance from your consumer unit to the garden to account for voltage drop over the 4m unit's location.

• Standard Requirement: Typically requires 6mm² or 10mm² 3-core SWA (Steel Wire Armoured) cable.
• Final Connection: The Barrel Sauna is supplied with internal pre-wiring for the Colour-Changing LED system. Your electrician must perform the final termination of your SWA cable into the Harvia Harvia Clindro heater terminals and ensure the LED transformer is correctly spliced.

4. Integrated Technology

• Lighting: The LED system is integrated into the interior and is powered via the main sauna circuit.
• Heater Controls: The Harvia Clindro features integrated manual dials on the base of the unit for temperature and timing (60-minute session timer with an 8-hour delay function).

5. Summary Table for Your Electrician

Final Instruction for the Homeowner:

Please ensure your electrician verifies that your property’s total load capacity can accommodate an additional 6.8kW demand. You must obtain an Electrical Installation Certificate (EIC) upon completion. This document is required to validate your product warranty and ensure the safety of all users.

Delivery & Installation Guide Barrel Sauna (4m)

Model: The Grand Barrel | 6.8kW Ergonomic Social Suite

1. Site Foundation & Preparation

The 4m Barrel requires a foundation that accounts for both its length and its concentrated weight points (the cradles).

• The Base: A perfectly level, solid base is mandatory. We recommend a concrete pad, a level run of heavy-duty paving stones, or a reinforced timber sleeper frame.
• Precision Leveling: Because the barrel relies on interlocking staves and stainless steel tension bands, any "twist" in the base will cause gaps in the timber or prevent the 8mm Panoramic Glass door from sealing.
• Clearance: Allow a minimum of 500mm around the perimeter. You will need this space to tighten the tensioning bands during the first month and for applying the annual "Natural Effect" timber stain.

2. Delivery & "The Lifting Service"

• Standard FREE Delivery: This is a kerbside delivery. The sauna is delivered as a palletised kit. Due to the 4000mm length, the pallets are substantial.
• Access Requirements: Verify that you have a clear, straight path to your garden. 4-meter timber staves cannot be easily "pivoted" through tight house corridors or narrow L-shaped alleyways.
• Lifting Service (Upon Request): * If manual transit to the garden is restricted, we can arrange a HIAB (crane truck) delivery.
• Capability: The crane can lift the pallets over fences or walls where appropriate and safe.

• Action: Please provide a site video for a bespoke lifting quote.

3. Physical Assembly Considerations

• Timber Handling: The unit is constructed from 42mm side timber and 24mm front/back panels. While Spruce is manageable, the 4m lengths require at least 3 capable adults to ensure staves aren't dropped or damaged during assembly.
• Glass Safety: The Panoramic Bronze Safety Glass door is a high-value, heavy component. It should remain in its protective packaging until the barrel structure is fully tensioned and stable.
• Inspection: You must inspect all components upon kerbside delivery. Report any transit damage within 24 hours.

4. Electrical Supply (Customer Responsibility)

The Harvia Harvia Clindro (6.8kW) heater is an electric stone engine that requires a dedicated power supply.

• The Requirement: A dedicated 32-Amp single-phase supply is mandatory.
• Electrician’s Role: You must hire a qualified, Part P registered electrician to run an SWA (Steel Wire Armoured) cable to the site.
• Note: Oasis Outdoor Living / Woodchop is not responsible for the final electrical connection. A valid Electrical Installation Certificate (EIC) is required to validate your warranty.

5. Installation Options

• Professional Installation: Price Available on Request.

• Recommended for the 4m model. Our team will correctly space the support cradles, interlock the 4m staves, and professionally fit the Katepal roof shingles.
• Includes a 2-year structural warranty.
• Self-Assembly:
• Requires a high level of DIY confidence. Ensuring the barrel is "square" before tightening the bands is vital for structural integrity.
• Includes a 1-year structural warranty.

6. Commissioning & First Heat

• The "Settling" Period: During the first 2–3 heat cycles, the 42mm timber will expand and contract. You may need to slightly adjust the tension of the stainless steel bands using a standard wrench.
• LED Sync: Test the colour-changing LED system once the electrician has completed the connection.
• Drainage: Ensure the built-in drain tap is positioned at the lowest point of the barrel's curve to allow for efficient wash-down after sessions.

Oasis Outdoor Sauna Range — Manufacturer's Warranty

This manufacturer's warranty is provided by Oasis Outdoor Living UK Ltd (the manufacturer). Balance Recovery is your authorised retailer for the Woodchop Outdoor Sauna range and your first point of contact for any warranty claim.

Every sauna in the Woodchop Outdoor Sauna range has been crafted from premium thermowood and timber to deliver exceptional performance, reliability and years of authentic sauna enjoyment. To reflect our confidence in the quality of every cabin, Oasis Outdoor Living UK Ltd provides the following manufacturer's warranty for saunas installed for private domestic use within the United Kingdom. This warranty applies across the sauna range and, where relevant, references your Harvia heater and control unit.

1 Year Warranty on the Timber & Cabin Structure

The timber cabin structure, supporting framework, benches, door and glazing frames are warranted by Oasis Outdoor Living UK Ltd against defects in materials or workmanship that affect the structural integrity of the sauna under normal residential use. Timber is a natural material: normal movement, expansion and contraction, colour change, resin bleed and weathering are inherent characteristics of the material and are not considered defects.

2 Year Warranty on the Harvia Heater & Control Unit

Your Harvia heater and control unit carry the Harvia manufacturer's warranty against defects in materials or workmanship for a period of 2 years. This cover is conditional on the heater being installed and connected by a qualified electrician in accordance with BS 7671 (the IET Wiring Regulations). Arranging this installation is the responsibility of the customer, and a valid Electrical Installation Certificate (EIC) may be required to support any warranty claim relating to the heater, control unit or electrical connection.

Warranty Registration

To receive the full benefits of this warranty, your sauna should be registered within 14 days of delivery. Failure to register within this period will reduce the timber and cabin structure warranty to the statutory minimum from the original date of delivery. Proof of purchase is required for all warranty claims. Please retain your Harvia documentation and your Electrical Installation Certificate (EIC), as these may be required to support a heater or electrical warranty claim.

Reporting Transit Damage

Any missing, damaged or incorrect parts should be reported to your authorised retailer within 3 days of delivery. Failure to report transit damage within this period may affect your entitlement to a warranty claim relating to those items.

Making a Warranty Claim

Please contact the authorised retailer from whom your sauna was purchased — Balance Recovery (contact@balancerecovery.co.uk). If you are unable to obtain assistance from your retailer, please contact:

Oasis Outdoor Living UK Ltd Unit 9 Albert Martin Business Park Kirkby Road Sutton-in-Ashfield Nottinghamshire NG17 1GZ

Warranty claims should be submitted within 30 days of discovering the fault and should include:

• Proof of purchase.
• Product serial number (or photograph of the product identification label) and, for heater claims, the Harvia model and serial number.
• A description of the fault.
• Photographs or videos showing the issue.
• Installation photographs where requested.
• For any heater, control unit or electrical claim, a copy of the Electrical Installation Certificate (EIC) confirming installation by a qualified electrician in accordance with BS 7671.

Oasis Outdoor Living UK Ltd reserves the right to inspect the product or request additional information before approving any warranty claim. Claims relating to the Harvia heater and control unit are assessed under the Harvia manufacturer's warranty. Where a warranty claim is accepted, Oasis Outdoor Living UK Ltd may authorise a repair or replacement of the defective component at its discretion. Customer-replaceable components may be supplied directly where appropriate. Replacement warranty parts are normally dispatched within 48 hours of an approved claim, subject to stock availability.

Where additional investigation is required, Oasis Outdoor Living UK Ltd reserves the right to appoint an authorised representative or independent inspector to assess the product. Travel or call-out charges may apply where the installation falls outside an authorised retailer's normal service area or where the reported fault is found not to be covered by this warranty.

Warranty Limitations

This warranty applies only to the original purchaser and only while the sauna remains installed at its original domestic installation address within the United Kingdom. The warranty period begins on the original date of delivery. The sauna must be installed, operated and maintained in accordance with the installation, operating and maintenance instructions supplied with the product.

This warranty does not cover defects, failures or damage resulting from:

1. Normal wear and tear, cosmetic ageing, fading or surface marks.
2. Natural timber movement, expansion, contraction, splitting, warping, resin bleed, colour change or weathering inherent to a natural material used outdoors.
3. Failure to treat, seal, oil or otherwise maintain the timber as recommended in the supplied instructions.
4. Improper installation, relocation or transportation.
5. Installation or electrical connection of the Harvia heater or control unit by anyone other than a qualified electrician working in accordance with BS 7671, or the absence of a valid Electrical Installation Certificate (EIC).
6. Misuse, abuse, negligence or accidental damage.
7. Commercial, rental or public use.
8. Failure to follow the installation, operating or maintenance instructions.
9. Exposure to extreme weather, standing water, flooding, freezing, power surges or other events beyond reasonable control.
10. Repairs or servicing carried out by anyone other than Oasis Outdoor Living UK Ltd, Harvia, or an authorised service representative.
11. Unauthorised alterations or modifications.
12. Continued use of the sauna or heater after a fault has become apparent.
13. The use of non-approved replacement parts or accessories.
14. Damage occurring during transportation by anyone other than Oasis Outdoor Living UK Ltd or an authorised retailer.

This warranty is limited to defects arising from manufacturing or material faults and does not include labour charges, transportation, crane hire, removal, reinstallation or consequential losses unless required by applicable law. Replacement components supplied under this warranty remain covered only for the unexpired balance of the original warranty period.

Genuine Parts & Accessories

To ensure optimum safety, reliability and long-term performance, only genuine replacement parts and Oasis Outdoor Living approved accessories should be used, and only genuine Harvia parts should be fitted to the Harvia heater and control unit. The use of non-approved replacement parts or accessories may invalidate this warranty where they are found to have contributed to the failure.

Service Commitment

Our experienced after-sales team will keep customers informed throughout the warranty process and work to resolve approved warranty claims as quickly as possible.
