The Wellness One 5-Year Guarantee
Every Wellness One outdoor sauna carries a 5-year guarantee — the longest guarantee in the outdoor sauna market. This is not a marketing claim; it is a reflection of the build quality and specification of every sauna we produce.
What the Guarantee Covers
The 5-year guarantee covers:
- All structural components — panels, frame, roof
- The heater (Huum or Harvia)
- Double-glazed aluminium windows and doors
- All electrical systems and controls
- External cladding (subject to proper maintenance)
- Interior thermally modified aspen
If any covered component fails within 5 years of installation, Wellness One will repair or replace it at no cost to you.
How It Compares
| Sauna Type | Guarantee |
|---|---|
| Barrel saunas | 1 year |
| Mid-range (mass market) | 2 years |
| Wellness One | 5 years |
Why We Can Offer 5 Years
The 5-year guarantee is possible because of the specification. 100mm SIP insulation is structurally robust and dimensionally stable. Double-glazed aluminium windows and doors do not warp, crack, or fail in the way that timber-framed single-glazed windows do. Huum and Harvia heaters are built to last decades. Thermally modified aspen is resistant to moisture, mould, and bacteria.
The Long-Term Ownership Case
A Wellness One sauna is designed to last 25 years. The 5-year guarantee covers the period when any manufacturing defects would typically manifest. After 5 years, the sauna should require only routine maintenance — annual wood treatment and periodic heater stone replacement.
