Sauna and steam room calculators
Six free tools for sizing, budgeting and specifying a sauna or steam room in the UAE. They use the same arithmetic we use when we quote, and the method behind each is written out in full rather than hidden.
Sauna heater size calculator
Sizes the heater on cabin volume with corrections for glass and masonry, and tells you whether you need three phase.
Open the tool Wet heatSteam generator size calculator
Sizes the generator on volume and tile thermal mass rather than floor area — the error behind most disappointing steam rooms.
Open the tool Dry heatSauna room sizing chart
Enter your space and see how many people fit, the bench run and the clear floor left over. Plus a chart from capacity to dimensions.
Open the tool Wet heatSteam room sizing chart
Capacity, bench run, the ceiling fall to build in and the drainage each size needs.
Open the tool CostsInstallation cost estimator
Our own installed price bands, adjusted for size, site condition, finish level, emirate and board capacity.
Open the tool CostsRunning cost calculator
Monthly running cost at your own DEWA rate, with warm-up separated from the session.
Open the toolWhy we publish the method, not just the answer
Every calculator here shows its working. That is deliberate. The specification errors we are called out to correct — a heater sized on floor area, a generator chosen without reference to the tile, a ceiling poured flat — all survive because nobody outside the trade knows what question to ask.
If a contractor's sizing disagrees with these tools by more than one step, that is a reasonable thing to raise. Ask them how they arrived at it. The answer tells you a great deal about whether they build these rooms or resell them.
Questions we get asked most
Are these tools free?
Yes, with no sign-up and nothing to enter beyond your dimensions. They run entirely in your browser and nothing is sent anywhere.
How accurate are they?
The sizing calculators use the same arithmetic we use when specifying a job, so they will put you within a size. The cost calculator uses our own published price bands. None of them can see what is behind your walls, which is what a site survey is for.
Can I use these if I am not buying from you?
Of course. Take the numbers to whoever you like. If a contractor's sizing disagrees with these by more than one step, ask them to show their working — the calculation method is set out in full on each page.
Why publish these at all?
Because the most common failures in this market are specification failures — heaters sized on floor area, generators sized without reference to the tile, ceilings poured flat. Anything that makes those harder to get wrong is good for us as well as for you.
