Comparison with Gym Membership
A premium gym membership with sauna access costs £80–£150 per month per person. For a family of four:
- 4 × £100/month = £400/month = £4,800/year
- Over 25 years: £120,000
A Lifestyle 4 at £28,080 (inc. VAT) costs £3.08/day over 25 years — a fraction of the gym membership cost, with unlimited access, no travel time, and no membership fees.
Running Costs
The 100mm SIP insulation in Wellness One saunas significantly reduces running costs. A typical session costs £1–3 in electricity depending on model size and tariff. Over 25 years at 3 sessions per week, running costs are approximately £3,900–£11,700 — a small addition to the capital cost.
Property Value
A high-quality outdoor sauna is increasingly viewed as a premium garden feature. Estate agents report that well-specified outdoor wellness features — including saunas — are increasingly sought after by buyers in the £500,000+ property market. The impact on property value depends on the local market, but a professionally installed Wellness One sauna is a positive addition to most properties.
