Frequently Asked Questions
Is the heater included in the price?
Yes. The ฿172,999 price includes the cabin, the 7kW TÜV certified stone heater, volcanic stones, heater guard and the full accessory set. Installation is the only optional extra.
How hard is it to assemble?
Two people with basic tools can assemble it in a weekend. The panels arrive pre-built, so you are joining sections, not constructing walls. If you would rather not, our team can install it for you.
Do I need an electrician?
Yes. The 7kW heater runs on a dedicated 240V single-phase circuit with a 40A breaker and 30mA RCD, and it must be connected by a licensed electrician. Wiring specifications are in the Tech Specs section.
Will it work in an air-conditioned room?
Yes. Indoor saunas are self-contained and insulated, so the room's air conditioning does not affect performance. Choose a spot with a level floor, ventilation nearby and access to the dedicated circuit.
Can I get it in a different size or timber?
This kit is fixed at 1800 x 1800 x 2100mm in Canadian Hemlock. For other sizes, layouts or timbers such as Red Cedar or Hinoki, our custom indoor saunas are built to your specification.
Does it come with audio?
Bluetooth audio is available as an optional add-on — ask when ordering and we will include it in the kit.

Delivery

Free delivery across Thailand. Your sauna ships flat-packed as a complete kit with all panels, benches, hardware and accessories. Lead time is confirmed at the time of order.

Installation

The kit is designed for self-assembly — two people with basic tools can have it standing in a weekend. Panels are pre-built, so assembly is a matter of joining sections rather than building from boards.

Prefer to skip the toolbox? Our installation team can assemble the sauna in your space and commission the heater, so your only job is the first session. Installation is available as an add-on at checkout or by quote.

The 7kW heater requires its own dedicated circuit, installed by a licensed electrician. Full electrical requirements are listed under Tech Specs.

Timber options
Japanese Cedar

Sugi cedar. Warm golden tone, naturally aromatic, and lighter in colour and weight than the western cedars. A softer look than pine without the price of red cedar.

Hemlock
Red Cedar

The benchmark sauna timber. Rich reddish tone, deeply aromatic when hot, and naturally resistant to moisture and decay. It also has a low thermal conductivity, so the bench surface stays comfortable to sit on at temperatures where other timbers do not.

Warranty

If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.

If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.

Care & Maintenance

After each session: prop the door open and let the cabin dry. This single habit does more for the life of a sauna than anything else on this list.

Weekly: wipe the benches with warm water and a soft cloth. No detergent, no bleach. Sauna timber is left unsealed on purpose so it can breathe and absorb moisture.

Monthly: check the heater stones. Stones break down with heat cycling. Restack them so air can move between them, and replace any that have cracked.

Yearly: inspect the roof shingles and the door seal, and check that fixings are still tight. Timber moves through a Thai wet season and a bolt that was tight in January may not be in September.

Exterior timber can be oiled if you want to hold the colour. Left alone it weathers to a silver grey, which is a finish rather than a fault.

This quote is valid for the period stated on it. Prices and product availability are subject to change after the validity period.

Payment Schedule
Deposit required upon order confirmation. The remaining balance must be received in full prior to delivery.

Deposit Forfeiture
The deposit is non-refundable. If the Customer cancels after production has commenced or refuses delivery, RonYen Wellness retains the deposit as liquidated damages.

Delivery Date
An estimated delivery date is agreed at the time of order confirmation. The Customer must ensure the delivery location is accessible and a responsible person is present on the agreed date.

Failed Delivery Fee
If delivery cannot be completed due to the Customer's unavailability on the agreed date, a fee of 1,000 THB per day applies until delivery is successful, payable before the goods are released.

Rescheduling
Any change to the agreed delivery date requested by the Customer must be made at least 7 days in advance and is subject to the availability of RonYen Wellness.

Site Preparation
The Customer is responsible for ensuring the installation site meets all requirements, including structural load capacity. Ice baths and saunas are heavy when loaded, and the Customer must ensure the surface can safely support the full weight.

Common questions

Everything you want to know about saunas & heaters

Outdoor and indoor cabins, barrels, cylinders and sauna + shower combos — from a compact one-person unit up to ten-person commercial rooms, all customisable to your space. Browse saunas.

Western Red Cedar and Finnish Thermo Pine both handle heat and humidity beautifully; Hinoki is our premium pick. We’ll match the timber to your budget and location.

Outdoor saunas are fully weather-sealed for gardens, rooftops and pool decks; indoor models are built for bathrooms, gyms and spare rooms. Both use indoor-rated electric heaters.

Most home saunas run on a dedicated single- or three-phase circuit sized to the heater. We’ll confirm the exact electrical requirement in your quote.

Both are food-grade and corrosion-resistant; 316 adds extra protection for coastal and chlorinated environments. We recommend the right grade for your site. See ice baths.

Ice works to get started, but a chiller holds a precise temperature day after day with no effort — the easiest way to make cold therapy a daily habit.

Our chillers take the water down to around 3°C and hold it there. Most people plunge between 3–10°C depending on experience.

A built-in filtration and sanitation cycle keeps the water fresh for weeks. We’ll walk you through simple water care at handover.

We’re open now in Chonburi, Thursday to Sunday, with Founding Member pricing until 30 September. The full experience opens 4 September — book ahead to be sure of a spot. Book a visit.

The Garden runs on advance bookings so every session has the space to itself — so book ahead if you can. That said, if you're passing and spot us, scan the sign at the gate or give us a call, and if there's room in the current session we'll happily wave you in.

Saunas, ice baths, a swimming pool and shaded lounge areas — everything you need for the full hot-and-cold circuit. Explore the garden.

The Wellness Garden is in Chonburi, easily reached from Bangkok and Pattaya. Full directions and parking details are on the garden page.

Yes — most saunas assemble in a day with two or three people and clear instructions. Prefer it done for you? Our team can handle the full install. Installation service.

Delivery to the spot, full assembly, levelling, heater fitting and a handover walkthrough so it’s ready to use the same day.

A firm, level base — a concrete pad, deck or paved area — plus a nearby power point. We’ll send a simple prep checklist before delivery.

Final connection should be made by a licensed electrician. We provide the full specification and can recommend trusted local contractors.

Yes — we deliver right across Thailand by freight, and ship internationally on request. Delivery details.

Most saunas are ready eight to ten weeks from order. Once built, freight to your address typically takes a few days, with tracking provided.

Standard nationwide delivery is included. For tricky access — rooftops, tight lanes or upper floors — we’ll quote any crane or extra handling up front.

Everything ships in a purpose-built timber crate to protect the timber and glass in transit — and the crate is easy to dispose of or repurpose.
