Saunas & ice baths in Sire & Tanjung
The north coast. Calm water, large plots, and the only part of the island where we are regularly asked to think in guests-per-hour.

On the ground
Building in
Sire & Tanjung
Sire and Tanjung are where Lombok's resort development is concentrated, and the work here is different in scale rather than in kind. The physics is the same. The question being asked is not.
Throughput, not seats
On a private villa the question is how many people sit down. On a resort it is how many guests move through per hour, which is a completely different sizing exercise. A room that comfortably seats six does not serve six guests an hour — it serves fewer, because it has to recover between sessions, and because guests do not arrive in tidy groups.
So a resort build starts from a schedule: sessions per day, guests per session, recovery time, and who is cleaning it between. That leads to decisions a villa never faces, like whether two smaller rooms beat one large one (they usually do), and whether the plunge needs UV on top of ozone (with that many bodies, yes). The framework for the numbers is in wellness for boutique hotels.
Calm water, still salt
The north coast is sheltered and the sea here is flat compared to the south. It makes no difference to the specification. A4/316 throughout, and a maintenance schedule that assumes daily commercial use — which is a considerably more serious document than the villa version. Under daily load, a bench that would be resanded annually at a private house needs looking at quarterly.
Large plots, long runs, real civils
Plots up here are big, which means the same long-run problem as the south-west coast but with more of everything: longer cable runs, longer water runs, and genuine civils. On the upside, three-phase is more often already in place on a resort property, which removes the constraint that dominates most of our other jobs.
Access is generally good — proper roads, room to turn a truck — so unlike the Gilis, freight is not a design constraint here. That opens up the custom end of what we do: larger rooms, bigger glass, and things that would never cross a beach.

Questions
Sire & Tanjung
answers.
How do you size a sauna for a resort?
From a schedule, not a seat count. Sessions per day, guests per session, recovery time between them, and who cleans it. A room that seats six does not serve six guests an hour because it has to recover. Two smaller rooms usually beat one large one, and at resort volumes the plunge needs UV on top of ozone.
Is three-phase power available in Sire and Tanjung?
More often than elsewhere on the island — resort properties frequently already have it, which removes the constraint that dominates most of our jobs. Plots are large though, so long cable and water runs become the design issue instead, and voltage drop over distance has to be calculated rather than assumed.
Does a resort sauna need a different maintenance schedule?
Yes, and it is a considerably more serious document. Under daily commercial use in sea air, a bench that would be resanded annually at a private villa needs inspection quarterly. Stones, seals, fixings and water treatment all move to a much tighter cycle. We set the schedule at handover and offer servicing against it.
