The hotel economics, on your numbers.
Three revenue lines, one ground: the NOOK Sauna sold by the private hour, treatment rooms that arrive finished, and the changing room that keeps the circuit outdoors. Modelled on your numbers — not a stock promise.

VisualisationWhat the market is charging.
None of these are NOOK installations, and no affiliation is implied — they are the market evidence: listed prices and access policies at named properties.
One private hour, sold seven nights a week.
The unit of revenue is the private hour: a couple books the sauna and plunge to themselves, housekeeping turns it round like a room, and the calendar does the rest. Your rate card sits where your property sits. The starting arithmetic below models session revenue alone — the first of the three lines.
Session line only — the ADR and OTA effects, housekeeping and your cold-water scope are not modelled. Quoted in USD; EUR and GBP quotes issued with the dossier.
For hotel, glamping and short-let segments we model payback at 18–36 months end to end — and the number that matters is yours: the design consultation brings the model in spreadsheet form, built on your ADR, your occupancy, your session pricing. Your inputs, our arithmetic.
A note on benchmarks: we do not treat any published sector uplift as a forecast for your property. Sector data tells you the category moved. The dossier model tells you what YOUR ground could do.
What the hotel dossier proves.
CE marked; tempered safety glass EN 12150; heater electrical safety EN 60335-2-53. Compliance documentation ships component by component.
Structural warranty: 1 year commercial, extendable to 3 — 3 years residential. Every component coded; each building ships with its own building file.
Run directly by NOOK. Housekeeping turns the cabin round like a room; staff pre-heat by app before the guest walks over.
