Investor guide
A sauna and ice bath earn for a Bali rental villa through three numbers: average daily rate (ADR), occupied nights and, later, resale. Below: the sourced amenity data, a worked ADR-times-occupancy example and the payback against a villa set.

Wellness real estate crossed $584 billion in 2024 and is forecast to double by 2029 (GWI). On the ground in Bali that macro trend turns into three concrete questions: resale premium, nightly rate, and occupancy. The sourced answers.
The strongest number in the field comes from the Global Wellness Institute's review of 300+ studies: homes with wellness infrastructure command 10-25% sale premiums. In a US survey of 6,000 buyers, wellness features out-ranked floor area as a purchase driver (America at Home / NAR). Bali's premium villa market - fed by 6.33 million foreign arrivals in 2024 - is exactly the segment where those preferences shop.
Short-term rental data is unusually clean here: AirDNA amenity analysis shows hot tubs lifting nightly rates +14.3%, saunas +7.4%, pools +9.5%. Note what that means in combination: a villa already has the pool; the contrast set is the differentiator still available. At a $350/night villa, +14% is ~$50/night - against a villa set at Rp 195-270 juta, the payback conversation runs in seasons, not decades. Vendor claims of '+25-30% with sauna and plunge' circulate; treat those as top-of-market anecdotes, not baselines.
The AirDNA amenity figures are uplifts on the nightly rate (ADR). Revenue, though, is ADR multiplied by occupied nights, so the same uplift is worth more in a villa that is full more often. The example uses the $350-a-night villa above, an illustrative exchange rate of Rp 16,000 per US$, 65% occupancy and the villa set band from our pricing page (Rp 195-270 juta). Every assumption is illustrative - swap in your own ADR and occupancy.
| Line | Sauna-level uplift (+7.4%) | Hot-tub-level uplift (+14.3%) |
|---|---|---|
| ADR before | $350 | $350 |
| Uplift per occupied night | about $26 | about $50 |
| Occupied nights a year at 65% | about 237 | about 237 |
| Extra revenue a year | about $6,100 (about Rp 98 juta) | about $11,900 (about Rp 190 juta) |
| Tub electricity (about Rp 214 ribu a month) | about Rp 2.6 juta a year | about Rp 2.6 juta a year |
| Simple payback on a Rp 195-270 juta villa set | about 2-2.8 years | about 1-1.4 years |
| Occupancy | Occupied nights | Extra revenue at +7.4% | Extra revenue at +14.3% |
|---|---|---|---|
| 50% | about 183 | about Rp 76 juta | about Rp 146 juta |
| 65% | about 237 | about Rp 98 juta | about Rp 190 juta |
| 80% | about 292 | about Rp 121 juta | about Rp 234 juta |
Three readings matter for an investor. The uplift figures are platform averages, not a Bali appraisal - treat the sauna-level column as the base case and the hot-tub-level column as the upside. The example holds occupancy flat: AirDNA's amenity data measures rate, and any extra bookings from ranking higher in the amenity filter are upside we do not count. And the extra revenue is gross: deduct management commission, platform fees and the sauna's own power (its heater kW times hours of use) before comparing the set with other capex.
From our handovers with agents present, the wellness features that survive due diligence: equipment with warranties and a service contract (a 3-year shell / 2-year chiller paper trail transfers with the sale), running costs in writing (≈ Rp 214 ribu/month for a lidded tub reads very differently from 'unknown'), and compliance basics - proper electrical work, drainage, heater certificates. An orphaned imported tub with no local service history is a discount conversation; a documented zone is a premium one. That documentation habit is the production page's whole argument.
Send photos of the garden or rooftop and your current ADR: we return a placement sketch, the villa set budget and a payback sheet within two working days.
The villa set - 2-person sauna + one tub + chiller, Rp 195-270 juta - covers the listing keywords and the guest ritual. Bigger only if the villa hosts retreats.
The opposite, when documented: warranties transfer, the service contract novates, the manual is in EN/ID. We hand over that folder at every install.
Terrazzo for heavy-rotation rentals (guest-proof, minimal upkeep), wood where the listing sells warmth. The wood guide and gallery settle it per property.
