Design your circuit
Choose the heat, choose the cold, watch the baht add up
Pick how many seats the sauna needs, whether the cold side is a pool, a duo or a tub, and which extras you want. The page sizes the heater and the chiller from the physics, shows an indicative range in baht with a dollar hint, and sends your choices to WhatsApp as a written brief.
How the sums work
- Heater: about 1 kW for each cubic metre of cabin, with an allowance for glass, so changing the seats changes the Harvia on the list.
- Chiller: 1 HP holds up to 260 litres at 3-5 °C, 2 HP up to 570, 4 HP up to 1,200, assuming 35 °C air. Pools of about 1,100 litres take a 4 HP unit.
- Range: components add up with a small discount when they are built together; shipping is allowed for, site works are not.
- Dollars: a hint at 36 baht per dollar, for orientation only.
What the page cannot know: your slab, your sun, your electrical supply and how far the plant sits from the pool. Those arrive in the free layout, ready in up to five working days.
Is the number a quote?
It is an honest orientation range. The quote comes from the layout, which accounts for access, power, finish and shipping, and it is free.
Can I configure only the cold side?
Yes. Choose no sauna and the page sums the pool, duo or tub, the chiller and the extras.
What does 'chiller included' mean for a pool?
Pools and the duo already contain their refrigeration, sized for 35 °C air. Tubs are priced separately from their chillers, and the page adds the right one.
Range looks right?

Start with a photograph
Send the corner of the garden, the terrace or the plant room you have in mind. We answer with questions first, then a layout and a range.
