Cube Sauna Room – 4 Person

The iconic curved silhouette of a traditional barrel sauna — handcrafted in Thailand by our Finnish master builder. This timeless design combines Nordic heritage with proven thermal efficiency, creating a striking focal point for any outdoor space.

This model measures 2100 mm long x 2100mm high and comfortably accommodates 4 people. The distinctive cylindrical shape isn't just beautiful — it promotes natural heat circulation, warming the interior faster and more evenly than conventional rectangular designs.

Precision-milled timber staves lock together using traditional tongue-and-groove joinery, secured by adjustable stainless steel bands that maintain structural integrity as the wood naturally expands and contracts with temperature changes. The curved walls direct heat downward from the ceiling, eliminating cold spots and reducing energy consumption.

Choose from three premium timbers: Teak, Red Cedar, or Thermowood Pine. Each is selected for dimensional stability and performance in high-heat, high-humidity conditions.

The sauna arrives as pre-cut stave bundles with all hardware included — assembly follows a straightforward sequence that most DIYers complete in a single day. The curved components nest together naturally, guided by the steel bands. Professional installation available if preferred.

Every barrel sauna ships complete with a traditional, TÜV Safety Certified, stone heater featuring wall-mounted touchscreen control, volcanic sauna stones, ambient interior lighting, bucket and ladle set, thermometer, and sand timer. The optional Wi-Fi module enables smartphone control via the iOS or Android app.

Teak

• Distinguished tropical hardwood containing natural oils that repel moisture, decay and pests. Warm honey-gold colouring that develops character over time. Outstanding longevity with a refined, comfortable surface.

Red Cedar

• Select-grade softwood displaying rich reddish-brown hues and distinctive grain patterns. Naturally fragrant with inherent resistance to rot, insects and moisture — emitting a gentle woody aroma when heated. The benchmark timber for outdoor saunas and an enduring favourite across all settings.

Pine

• Traditional Nordic sauna wood offering a clean, pale appearance. Responsibly harvested softwood that excels in elevated temperatures. Budget-conscious option delivering authentic Scandinavian aesthetics.

Pine Shou Sugi Ban – Light

• Pine processed using the ancient Japanese charring method for improved resilience and a delicate smoky character. Light treatment maintains visible grain while adding protective qualities and modern appeal.

Pine Shou Sugi Ban – Medium

• Intensified charring produces a deep, lustrous surface with prominent grain definition. This traditional Japanese technique enhances weather resistance while creating a distinctive contrasting finish.

Pine Shou Sugi Ban – Dark

• Complete char treatment yields a bold charcoal-black exterior with dramatic textural depth. Superior surface protection combined with striking visual presence. A signature piece for contemporary sauna architecture.

After Each Session

• Wipe bench surfaces with a dry towel to remove moisture
• Leave door ajar for 15-30 minutes to ventilate
• Empty any water from bucket

Weekly Tasks

• Sweep or vacuum the slatted floor
• Wipe benches with damp cloth (water only)
• Check heater stones are properly stacked
• Clean door glass inside and out

Monthly Attention

• Scrub benches with soft brush and mild soap, rinse well
• Sand any rough spots with fine sandpaper (180-220 grit)
• Inspect door hinges and seals
• Check steel bands remain properly tensioned

Seasonal Care

• Inspect exterior timber for weathering
• Apply timber oil to exterior surfaces (Red Cedar and Thermowood benefit from annual treatment)
• Check steel band tension — adjust if timber has settled
• Have electrical connections inspected by qualified electrician
• Replace heater stones when they begin to crumble (typically 1-2 years)

Avoid

• Harsh chemicals or abrasive cleaners inside the sauna
• Sealing interior timber — it must breathe
• Leaving wet items inside between uses
• Over-tightening steel bands — allow for natural timber movement
• Excessive water on heater — gentle steam only

Q: Why choose a barrel sauna over a rectangular cabin?

A: The curved interior promotes natural convection — hot air circulates efficiently rather than pooling at the ceiling. This means faster heat-up times, more even temperature distribution, and lower running costs. The iconic silhouette also creates a striking garden feature.

Q: How does the barrel construction handle Thailand's climate?

A: All our barrel saunas use timber selected for tropical conditions. The stave construction with adjustable steel bands accommodates the natural expansion and contraction that occurs with humidity changes. Teak and Thermowood Pine offer the best dimensional stability for humid climates.

Q: Is the barrel sauna weatherproof?

A: Yes. The tight tongue-and-groove joinery and curved design naturally shed rainwater. For additional protection in heavy rain areas, an optional canopy or shelter extension is available. The timber itself (particularly Teak and Thermowood) resists moisture penetration.

Q: Which timber is best for barrel saunas?

A: Red Cedar is the traditional choice — lightweight, aromatic, and naturally rot-resistant. Teak offers premium durability with minimal maintenance. Thermowood Pine provides excellent stability at a moderate price point. All three perform well; choose based on aesthetics and budget.

Q: How difficult is assembly?

A: More involved than flat-pack furniture but achievable for competent DIYers. The staves lock together progressively, with steel bands providing structural tension. Allow a full day for a 2-person model with 2-3 helpers. Detailed illustrated instructions guide each step. Professional installation is available.

Q: What foundation does a barrel sauna need?

A: Position on a level, stable surface that allows airflow underneath — concrete blocks, railway sleepers, or purpose-built cradles work well. The barrel should sit on support points, not directly on the ground, to prevent moisture accumulation and allow air circulation beneath.

Q: What electrical requirements apply?

A: The included heater requires a dedicated circuit. Single phase (200-240V) needs 28A capacity with 6.0mm² cabling. Three phase (380-415V) requires 9A capacity with 2.5mm² cabling. Installation by a licensed electrician is mandatory.

Q: How do I maintain the steel bands?

A: Check band tension seasonally. New saunas may require slight tightening after the first few months as timber settles. Bands should be firm but not over-tight — the timber needs room for natural movement. Stainless steel construction prevents corrosion.

Q: Can I add a changing room or porch?

A: Yes. Extended barrel configurations include a separate changing area within the barrel structure. External porches and shelters can also be added. Contact us to discuss options for your installation.

Q: What size barrel sauna do I need?

A: The 2-person model suits couples or solo use with room to stretch out. The 4-person accommodates small families or friends bathing together. The 6-person serves larger groups or commercial settings. We can build custom lengths for specific requirements.

Q: What's included with the barrel sauna?

A: Every barrel sauna includes: precision-cut timber staves, stainless steel tensioning bands, solid end walls with tempered glass door and window, traditional TÜV Safety Certified stone heater, wall-mounted touchscreen controller, volcanic sauna stones, interior light, wooden bucket and ladle, thermometer, sand timer, and comprehensive assembly guide (English).

Q: How long does delivery take?

A: Standard delivery is 4-6 weeks from order confirmation for most Thai locations. Custom sizes may require additional lead time. We confirm your specific delivery schedule during ordering.

Q: What are typical running costs?

A: Electric heaters typically cost ฿400-800 monthly for regular use (3-4 sessions weekly). Barrel saunas generally heat faster and retain warmth efficiently due to the curved design, often using less energy than equivalent rectangular cabins.

Q: Are barrel saunas suitable for commercial use?

A: Absolutely. The distinctive appearance makes them ideal feature installations for resorts, hotels, and wellness centres. The robust construction handles frequent use. Contact us regarding sizing and volume requirements for commercial projects.
