Polished Sauna Stones — Smooth Oval Löyly Stones Our polished sauna stones are machine-finished into uniform oval shapes, typically 5 to 8 centimetres in diameter, with a beautifully smooth surface. Unlike irregular volcanic stones that produce a fast, intense burst of steam, polished stones work differently — water rolls across the smooth surface and evaporates slowly and steadily, releasing gentle, continuous löyly.

This makes them particularly well-suited to therapeutic sauna sessions where a softer, more sustained heat is preferred over sharp blasts of steam.
The uniform size and shape of polished stones open up more creative stacking options than irregular stones allow:
– Pyramid style: Start with a circular base of larger stones and gradually reduce the size of each layer as you build upward, forming a tapered pyramid shape.
– Grid style: Stack stones crosswise in alternating layers, leaving a central chimney passage at least 10 centimetres wide to allow heat and steam to rise through the centre.
Whichever arrangement you choose, maintaining a vertical ventilation channel through the stack is essential. Without proper airflow, steam becomes trapped and stagnant, reducing the quality of your sauna experience and placing unnecessary strain on the heater.
The smooth, non-porous surface of polished stones produces significantly less mineral dust than irregular alternatives, keeping the air inside your sauna noticeably cleaner and fresher — a real advantage in enclosed sauna rooms.
Polished stones are also highly resistant to thermal stress and will typically last 8 years or more with proper care, roughly three times the lifespan of irregular volcanic stones. For saunas where longevity, clean air and visual presentation matter, polished stones are the premium choice.
The smooth surface of polished stones makes them well-suited for use with essential oil diffusion. However, never pour essential oils directly onto the stones — always use a dedicated aroma bowl or evaporator cup placed on top of the stone stack. This protects the stones and heating elements while allowing the scent to disperse evenly through the sauna.
Every sauna is built to your order. Production runs 8 to 12 weeks from the date your order is confirmed, then delivery on top. Timber is a natural material and shipping is a global business, so weather and freight conditions can move that. We tell you if your build shifts rather than letting the date pass quietly.
Delivery is included anywhere in Thailand. International shipping is quoted separately.
YOUR SAUNA ARRIVES IN A CRATE, AND YOU UNLOAD IT
The sauna ships in a sealed timber crate to protect the panels in transit. It is heavy. Crate weight and dimensions are listed in the specifications, and you should read them before you order.
Getting the crate off the truck is your responsibility. The driver is not equipped to lift it. Arrange a forklift, a small crane, or enough people, and have them there on the agreed delivery day. This is the most common cause of a failed delivery, and a failed delivery carries a fee.
Check the access route before you order. The usual problem is a gate or side passage narrower than the crate. Send us a photo of the approach and we will tell you whether it works.
INSTALLATION
Installation is not included and is priced by region, because that is what it costs to get a crew and a vehicle to you:
Central Thailand, from 15,000 THB
Southern Isaan, from 20,000 THB
Northern, Eastern and Western Thailand, from 25,000 THB
Northern Isaan and Southern Thailand, from 35,000 THB
Islands excluding Phuket, from 40,000 THB
You do not have to take it. Many customers stand the cabin up themselves.
ELECTRICAL WORK
We will install your sauna. We do not do the electrical wiring.
You will receive the full electrical specification for your cabin and heater, so your qualified electrician knows the load, the voltage, the current, the cable size and the breaker before they arrive. We will assist your electrician on the day of installation.
In Bangkok and Chonburi we can arrange the electrical work for you. Everywhere else in Thailand you will need to appoint your own licensed electrician.
The wall sections are built and finished at the factory, then crated. On site you are joining finished panels, not building them. Two people with basic hand tools have it standing in one to two days.
No specialist tools, no cutting, no finishing work. The printed manual and our video guides take you through it, and we are on the end of a phone, a chat or a video call while you work. That is included, with no time limit.
The cabin needs a level, load-bearing base that drains. Concrete, paving or a properly built timber deck all work. It does not need to be a slab, but it does need to be flat.
Heater wiring is the exception. That must be done by a licensed electrician, for the reasons set out under Delivery & Installation.
If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.
Structure and timber: 2 years
Walls, frame, benches, door and roof. If something fails we send a replacement part, or we come and repair it.
Electrical components: 1 year, by replacement
Heater, control panel, lighting and sensors. A failed unit is replaced rather than repaired, so you are not left without a sauna while something is sent away. The warranty covers the part. It does not cover rewiring or reinstallation.
Glass and hardware: 1 year
Tempered glass panels, hinges, handles and fixings.
Claims are handled in Thailand by our own team. There is no importer to go through and no overseas parts wait.
In practice we rarely use it. The cabins are heavily built and the electrical components are ones we have used for years and know well. Failures inside the warranty period are uncommon.
Looked after, a RonYen sauna and its equipment should give you 10 to 15 years of use, and often longer.
What is not covered: damage from misuse, modification, improper installation, lack of maintenance, or normal wear such as timber colour change with age. Timber darkens and moves. That is what timber does, and it is not a fault.
Inspect stones every 6 months for any signs of cracking or surface damage. Restack and re-space them to maintain proper airflow channels.
Never pour ice-cold water directly onto hot polished stones. A sudden temperature difference exceeding 200°C can cause the stones to crack. Always use room-temperature or warm water.
Rinse stones with clean water during restacking to remove any surface residue or dust.
Check that your ventilation channel remains open after restacking. Stones can shift and settle over time, blocking airflow through the centre of the stack.
Replace stones if you notice visible cracks, chips or a decline in steam quality. With normal use, polished stones last 8 years or more.
Only use clean water on your stones. Oils, beer and other liquids leave residue that builds up over time and can damage heating elements. Use an aroma bowl or evaporator cup instead.
Stock items can be returned within 7 days of delivery in resalable condition. Custom and made to order items cannot be returned once production has begun. Faulty goods are repaired, replaced or refunded at our cost.

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.

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. Where there is doubt, a qualified structural engineer must confirm load capacity. RonYen Wellness accepts no liability for damage resulting from installation on an inadequate surface.

Any disputes arising from this document shall be resolved through good-faith negotiation. If resolution cannot be reached, disputes shall be subject to the jurisdiction of Thai courts and governed by Thai law.
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.
