Open the pageTwelve notes, grouped by the question they answer
- Will it hold 4 °C in August? Sizing a plunge chiller when the air is 45 °C works three loads and two examples; outdoor sauna and wooden tub at 45 °C covers what sun does to a terrace.
- Is the equipment right for the supply and the glass? Heaters and chillers on Saudi 60 Hz and glass-front saunas in desert heat.
- How is it installed, and what does it cost? Sauna installation in Riyadh for villas, compounds and towers; what a custom sauna costs in the Gulf.
- Who uses it, and how are men and women kept apart? Gender-separated recovery zones and a padel club recovery room without a new building.
- What do consultants and operators need? A hotel hot-cold circuit spec sheet and water treatment for commercial cold plunges.
- What is the thing I am actually looking for? Sauna, steam room or hammam sorts the words buyers confuse.
- When should it be ordered? Planning around Ramadan and the season.
How the notes are written
Each note computes before it claims. Where an outside number is quoted, the source and the year are named in the text; where a rule depends on a ministry, a utility or a building manager, the note says what to ask instead of guessing. Every note ends with the questions to put to your own engineer and with links to the pages describing the matching equipment.

Describe the space and its users; the desk proposes the suite
One message starts the layout
Send a plan or three photographs of the space and say who will use it. The project desk answers with questions first, then a 3D layout and an indicative range.
