Budget ranges in baht
What a sauna and a cold plunge pool cost in Thailand, with the arithmetic showing
Every figure below is an indicative range in Thai baht, derived from our workshop price list at 36 baht to the US dollar with an allowance for shipping and tropical-grade specification. They are orientation figures: the free 3D layout, ready in up to five working days, turns them into a quote.
Saunas: seats, cabin and heater, in baht
| Seats | Cabin (inside) | Heater | Indicative range |
|---|---|---|---|
| Solo (1 seat) | 1.2 x 1.1 m | Harvia 3.5 kW | THB 205-275k |
| 2 seats | 1.6 x 1.3 m | Harvia 4.5 kW | THB 275-380k |
| 4 seats | 2.0 x 1.7 m | Harvia 8 kW | THB 380-540k |
| 6 seats | 2.3 x 2.1 m | Harvia 10.5 kW | THB 540-770k |
| 8 seats | 3.0 x 2.3 m | Harvia 15 kW | THB 720k-1.03M |
| 10 seats | 3.4 x 2.5 m | Harvia 18 kW | THB 880k-1.2M |
| 12 seats | 3.8 x 2.8 m | 2 x Harvia 12 kW | THB 1.08-1.48M |
Two glass walls meeting at a corner is the signature form; one glass wall with a full-glass door is the quieter variant. Heaters follow roughly one kilowatt per cubic metre of cabin, plus an allowance for glass, and from about 8 kW the heater is normally wired three-phase.

The cold side: pools, duos and tubs
| Build | What it is | Indicative range |
|---|---|---|
| Round plunge pool | built in, about 1,100 L, mosaic, flush with the deck, chiller included | THB 330-590k |
| Square plunge pool | built in, about 1,200 L, travertine edge at seat height, chiller included | THB 370-660k |
| Hot + cold pool duo | 38 °C and 4 °C side by side, one plant room, both pools included | THB 700k-1.25M |
| Compact solo tub | 250 L free-standing, tub only | THB 85-130k |
| Oval teak tub | 420 L, white liner, tub only | THB 120-175k |
| Round teak tub | 520 L, white liner, tub only | THB 105-145k |
| Double tub | 800 L, for two, tub only | THB 205-310k |
| Sunken stone tub | 1,000 L built into a deck, tub only | THB 250-425k |
Pools and the duo include their refrigeration, because a pool without cooling is just a pool. Tubs are priced separately from their chillers, so a tub set is the tub range plus the chiller range below. The cold plunge pool page and the duo page explain what the range buys.
Chillers are priced by the litres they hold
| Chiller | Holds 3-5 °C for up to | Typical partner | Indicative range |
|---|---|---|---|
| 1 HP | 260 L | 250 L compact tub | THB 105-140k |
| 2 HP | 570 L | 420 and 520 L tubs | THB 140-205k |
| 4 HP | 1,200 L | 1,100 L plunge pool, 800 and 1,000 L tubs | THB 220-330k |
Sizing assumes 35 °C air, which is why Thai installations are not shrunk to the temperate-climate table. Bigger shared pools run two units in parallel and are priced per specification. The reasons are in chillers for Thai heat.
Extras that change the feel more than the price
| Extra | What it does | Indicative range |
|---|---|---|
| Teak deck and platform | a dry, warm surface around the pool or tub | THB 35-65k |
| Low-glare LED lighting | underwater and path lights that do not shine at the neighbours | THB 16-28k |
| Aroma kit and accessories | buckets, ladles, thermometer, hooks | THB 8-16k |
| Shade pergola over the pool | takes sun off the water, which the chiller notices | THB 85-180k |
Whole circuits: a condo room, a villa, an estate, a club
| Circuit | Typical composition | Indicative range |
|---|---|---|
| Compact | 2-seat glass sauna, compact tub and chiller | THB 395-630k |
| Condo recovery room, about 12 m² | 2-seat glass sauna and a square plunge pool | THB 645k-1.04M |
| Villa | 4-seat glass sauna, round plunge pool and teak deck | THB 700k-1.1M |
| Estate | outdoor glass sauna, hot and cold duo and deck | THB 1.1-1.9M |
| Commercial | 8-12 seat glass sauna and one or two cold pools, per specification | THB 870k-2.23M |
Built together, a circuit costs slightly less than the same items bought one by one, because plant, freight and approvals are shared. The case notes show three of them in detail, and the configurator does the sums for your own combination.
Where the numbers come from
Our workshop price list is kept in US dollars. For Thailand it is multiplied by 1.1 to cover shipping and the hot-climate specification, then converted at 36 baht per dollar and rounded. If the exchange rate moves five percent, the figures here move with it, which is one reason they are ranges and not tariffs. USD equivalents appear in the configurator for orientation only.
What the ranges leave out
- Site works. A slab check, a reinforced base, retaining walls on a slope, drain runs and a plant niche built into masonry are part of the quote, not the range.
- Lifting and access. Cranes, hand-carry crews and night deliveries for a condo lift are itemised.
- Power. A three-phase upgrade or a new distribution board is usually the owner's electrician's job; we specify it.
- Approvals and tax. Building permits are the owner's responsibility, with our drawings; VAT is shown as its own line in the quote.
Indicative ranges as of October 2026. Prices are not a tariff: access, finish, sun, distance to the plant and shipping all move the number, and the free layout fixes it.
40 / 40 / 20, and why the last 20 waits for a test
Forty percent when you sign, forty when production is finished and the kit is released for shipping, twenty only after a signed temperature test on site: the pool at 3-5 °C, the sauna at working heat. Never one hundred percent up front. Corporate buyers and phased builds can agree stage payments at signing.
Why do you quote a range, not one price?
Because access, sun, power and distance to the plant genuinely change the work. The range is where most Thai projects land; the layout locks the figure before you pay a deposit.
Is VAT included?
The ranges on this page are before VAT, which appears as its own line in a quote. Thailand's statutory VAT rate is 10 percent, and the reduced 7 percent rate has been extended to 30 September 2027 (Royal Decree No. 807 B.E. 2569, as summarised by KPMG and PwC).
Can you quote in US dollars?
Yes. Many resort and developer buyers prefer a USD quote with the baht equivalent, and we agree the exchange date in the contract. Ask on WhatsApp.
What is the cheapest way into cold plunge?
A 250 litre compact tub with a 1 HP chiller, THB 190-270k as a set. A built-in pool starts near from THB 330k with its refrigeration.
