Holl’s Cocoon 130 | 2-Person Designer Outdoor Sauna

The Holl’s Cocoon 130 (HL-COCOON130-PK) is the 2026 benchmark for high-performance, compact outdoor wellness. Engineered specifically for the volatile UK and Northern European climates, the Cocoon 130 moves away from traditional "shed" aesthetics, offering a sophisticated, Black-Stained Canadian Pine exterior that serves as a striking architectural focal point for any garden or terrace.

With its iconic Half-Moon panoramic glazing, the Cocoon 130 creates a sense of infinite space within a compact 150 x 130 cm footprint. Crafted from 100% chemical-free, heat-treated timber, this sauna is designed for those who demand a professional-grade thermal experience without the massive footprint of a traditional barrel or cabin.

Why the Cocoon 130 is the 2026 Outdoor Leader:

1. Thermal Resilience: Heat-Treated Canadian Pine

In 2026, timber stability is the #1 ranking factor for outdoor durability.

  • Dimensional Stability: The Canadian Pine is heat-treated to remove moisture and resins, ensuring the cabin does not warp, shrink, or crack during frost-thaw cycles.
  • Natural Insulation: This 100% chemical-free process enhances the wood's thermal R-value, keeping the heat inside and the 4.5kW stove's energy consumption low.

2. Panoramic Wellness Design

The Cocoon 130 is engineered for "Visual Recovery."

  • Half-Moon Rear Glazing: A massive 8mm tempered glass rear panel allows you to integrate your garden's view into your session, reducing the "claustrophobic" feel of small outdoor units.
  • Designer Exterior: The waterproof black finish isn't just aesthetic; it’s a high-grade protective barrier that resists UV degradation and water ingress, backed by a 4-year wood warranty.

3. Sensory Lighting & Comfort

  • Abachi Wood Interior: While the exterior is rugged pine, the interior bench is crafted from Abachi. This premium wood stays cool to the touch, ensuring comfort even when the stove reaches peak temperatures.
  • Integrated LED Glow: Features moisture-sealed LED strips that provide a soft, ambient glow, perfect for evening sessions in the garden.

CRITICAL: NOTICE TO THE PROPERTY OWNER

Owner’s Brief for the Holl's Cocoon 130 Outdoor Sauna

The Cocoon 130 is designed for a traditional 4.5kW (Approx 19.6 Amps) sauna stove. This is a high-power outdoor installation that falls under UK Building Regulations (Part P).

THE GOLDEN RULE: While this document provides the manufacturer's technical requirements, you must always defer to the professional judgment of your Registered Electrician. They are the final authority on cable sizing, circuit protection, and local site safety. If their on-site assessment contradicts any part of this brief due to your specific property layout or existing infrastructure, follow the electrician’s instructions.

1. Power Infrastructure Requirements

The electrical feed must be built to withstand outdoor conditions and the sustained draw of a steam-generating stove.

Rating

Operating Amperage

Connection Type

Stove

4.5kW

Approx. 19.6A

Hardwired (SWA Cable)

Integrated LED Strips

Low Voltage

Included in Feed

Pre-wired to Sauna Hub

  • Circuit Specification: Typically, a dedicated 32A radial circuit using Steel Wire Armoured (SWA) cable is required. Your electrician will determine the exact cable gauge (e.g., 6mm² or 10mm²) based on the "voltage drop" over the distance from your house to the garden.
  • Outdoor Isolation: A weatherproof, lockable Double-Pole Isolation Switch must be installed. Your electrician will determine the safest location to ensure it is accessible but protected from steam.

2. Safety & Weatherproofing

  • RCD Protection: The circuit must be protected by a 30mA RCD at the main consumer unit.
  • IP Rating: All external connections must be IP65 rated or higher.
  • Earthing: Your electrician must verify that the earthing system is suitable for an outdoor structure where water and high heat are present.

3. Lighting & Control Hub

  • Integrated LED Strips: Ambient lighting is powered through the sauna's internal hub. Your electrician will connect this hub to the main incoming feed.
  • Stove Clearance: Your electrician must install the stove following the specific "safety distance" measurements provided in the stove manual to protect the Canadian Pine walls.

4. Installation Layout

  • Cable Management: Coordinate with your electrician to ensure the SWA cable enters the structure at a point that does not interfere with the Abachi benches or the panoramic glass rear.
  • Certification: Upon completion, your electrician must provide an Electrical Installation Certificate (EIC). This is required for your home insurance and to validate your 2-year electronics warranty.

Delivery & Installation Protocol: Holl’s Cocoon 130

HL-COCOON130-PK | Your Outdoor Wellness Project

The Cocoon 130 is an architectural outdoor sauna featuring heat-treated Canadian Pine and a panoramic "Half Moon" glass rear. Because it is an outdoor structure, the preparation for delivery and the assembly process are more intensive than an indoor infrared model.

1. Pre-Installation: Base Requirements

The Cocoon 130 must not be placed directly on grass or soil.

  • The Base: You must have a solid, level, and well-drained foundation (Concrete pad, level paving slabs, or a heavy-duty timber deck).
  • Footprint: The base should be at least 150 x 130 cm.
  • Drainage: Ensure the base is slightly elevated to prevent standing water from pooling around the bottom frame.

2. Choosing Your Installation Pathway

Pathway A: Professional Installation (Highly Recommended)

Due to the traditional steam nature and outdoor weatherproofing required, professional installation is advised.

  • The Service: Our team will assemble the heat-treated pine structure, install the interior Abachi benches, and seal the glazed panels.
  • Technical Commissioning: They will install the LED strips and ensure the structure is weather-tight. Note: The 4.5kW stove requires a separate hardwired connection by your electrician.

Pathway B: Self-Assembly (3-Person Task)

  • The Manpower: This is a heavy-duty 3-person build. The Canadian Pine sections are dense, and the panoramic rear glass requires two people to hold it steady while the third secures the frame.
  • Weatherproofing: You must follow the manual’s instructions for sealing joints precisely to maintain the "Waterproof" rating of the exterior.
  • Tools Needed: Spirit level, drill/driver, rubber mallet, and a ladder to install the roof sections.

3. Commissioning the "Finnish Ritual"

  • Stove Installation: The Cocoon is designed for a 4.5kW Vulkano Black stove (or equivalent). This must be hardwired by a professional (see Electrical Brief).
  • The First Heat: Run the stove for 1 hour at a moderate temperature without water to "cure" the stones and the heat-treated pine.
  • LED Sync: Test the integrated LED strips to ensure the ambient lighting is functional before the final trim is fixed.

Installation Readiness Checklist

  •  Inspection: Glass and pine panels checked within 24 hours of delivery?
  •  Base: Is there a level, solid concrete or decked pad ready?
  • Manpower: Do you have 3 adults available for the build?
  •  Stove: Have you ordered the 4.5kW stove and booked an electrician?
  •  Access: Is there a clear path to the garden for the 200cm tall panels?

Holl’s Cocoon 130 Outdoor: Warranty Statement

HL-COCOON130-PK | Your Outdoor Protection Terms

The Cocoon 130 is engineered for durability in an outdoor environment. To protect your 4-year structural and 2-year electronic coverage, the following installation and maintenance standards must be strictly observed.

1. Warranty Duration

Holl’s (Poolstar) provides a tiered warranty that reflects the resilience of the Cocoon’s specialist materials:

  • Wood Structure: 4-Year Warranty against manufacturing defects or structural failure of the heat-treated Canadian Pine.
  • Electrical Components: 2-Year Warranty covering the integrated LED Chromotherapy strips, the control hub, and internal wiring.
  • Note on Stove: If purchased separately, the 4.5kW stove is covered by its own manufacturer’s warranty (refer to the stove's manual).
  • Usage: These terms apply strictly to private domestic home installations.

2. Conditions for Validity

To maintain the validity of your warranty, the following criteria are mandatory:

  • Certified Hardwiring: The sauna must be hardwired by a Registered Electrician to a dedicated circuit. Any damage to the internal electronics or the stove caused by improper wiring, the use of extension leads, or failure to follow the electrician’s professional judgment will void the electrical warranty.
  • Structural Base: The sauna must be installed on a solid, level, and well-drained foundation (e.g., concrete pad, level paving, or reinforced decking). Movement or structural stress caused by placing the unit on grass, soil, or an unlevel base is not covered.
  • Outdoor Maintenance: The exterior features waterproof black paint. However, the wood is a natural product. To maintain the 4-year structural warranty, you must inspect the seals annually and ensure no standing water is allowed to pool against the bottom frame.

3. The 24-Hour Inspection Rule (Fragile Components)

  • Glazed Panels: The Cocoon 130 features a heavy-duty 8mm glass door and a panoramic "Half Moon" rear panel. You must unbox and inspect these and report any transit damage, chips, or cracks within 24 hours of delivery.
  • Post-Assembly: Once the sauna is assembled and fixed, glass breakage is considered accidental damage and is not covered under the manufacturing warranty.

4. Material Integrity & Care

  • Canadian Pine: The wood is heat-treated to ensure chemical-free durability. Minor surface "checking" (fine lines) or color variations are natural characteristics of timber exposed to the elements and do not affect structural integrity.
  • Black Exterior Finish: To protect the aesthetic warranty, clean the exterior only with a soft brush or damp cloth. Avoid high-pressure washers or abrasive chemicals.
  • Interior Abachi Wood: The benches should be protected from perspiration stains by the use of towels during every session.

5. Claims Procedure

In the event of a technical or structural issue:

  1. Records: Retain your original purchase record and the GTIN (HL-COCOON130-PK).
  2. Certification: For any electrical claims, you must provide the Electrical Installation Certificate (EIC) issued by your registered electrician.
  3. Photos: Photographic evidence of the base and the electrical isolation switch may be required to process a claim.
