From site survey to first session
Four stages, one payment schedule, and a service interval set by your climate rather than by a manual.
Site visit and survey
Laser measure, camera, the ground, the carry route from the nearest vehicle, the board or the inverter, the lift where there is one, and a water test where a steam room is involved.
Drawing and quote
A dimensioned drawing, the heater calculation with any altitude correction, the chiller sized against real ambient, and a price with access, shipping, the exposure package and services on their own lines.
Build
First fix — drain, extract, cable, circuits — while panels are made and long-lead items travel. The cabin is dry-assembled in the workshop before it leaves.
Handover and service
Commissioning with a thermometer and a stopwatch, staff training on commercial work, a spares kit with part numbers left on site, and the first service booked.
40% to start the drawing and order materials, 40% before shipping, 20% on commissioning.
What the survey actually measures
The room or the plot, obviously — but also the things that decide the price and the programme. Where the board is and what is on it. Whether the changeover feeds the circuits we need. The route from the nearest point a vehicle reaches to where the cabin will stand, photographed at every turn and measured at the tightest one. The ground, because a plinth pinned into rock and a raft on soft sand are different buildings. The water, where a steam room is involved, because borehole chemistry decides a generator's descaling interval.
On a commercial job it also measures the peak: how many people want the room in the busiest ninety minutes. Almost every gym and hotel underestimates this, and it is far cheaper to fix on a drawing than in year two.
What a quote from us shows
The heater size and the calculation behind it, including any altitude correction. The chiller capacity against the ambient we expect at your site, or an honest note that you do not need one. The exposure package for your climate. Access and shipping as their own lines. The services — drain, extract, cable, circuits. And the service interval, quoted with the installation rather than sold afterwards.
If a competing quote does not state those, it is not cheaper. It is less specific, and the difference appears later.
What happens while you wait
Long-lead imported items are ordered the day the drawing is signed, and the groundwork, the drainage and the electrical work happen while they travel. The cabin is dry-assembled in full in the workshop, photographed and numbered, then taken apart to ship — so assembly on site is days rather than weeks and nothing is discovered for the first time on your terrace.
Handover, and the six months after it
Commissioning with a thermometer and a stopwatch, not a handshake: the cabin is run up to temperature and timed, the chiller is run to setpoint, the cut-outs are tested and the water is tested.
On commercial work we train the team for two days on operation, cleaning chemistry, water testing and the log book, and we come back at six months to check the log is being kept. Maintenance teams turn over, and a suite run by somebody who was never shown how is broken by its second year.
