Say goodbye to wasted heat. The clever barrel design eliminates unused space (think circle inside a square), meaning your sauna heats up faster and stays warmer. Instead of letting heat get trapped at the ceiling like in a square sauna, the curved walls push warmth back down into the seating area — so you feel the benefit right where you want it.
Truly Low-Maintenance
Your sauna should be for relaxing — not repairing. Barrel saunas naturally shed rainwater and can handle heavy snow loads with ease. The tough polymer cradles mean you can set it up on almost any flat surface, and the Thermowood construction is naturally resistant to water and insects. Less hassle, more time to enjoy.
Energy-Saving Design
With less empty space to heat, your sauna uses less energy — saving you money in the long run. The thick wooden staves keep the heat where it belongs, while the exterior stays cool to the touch for safe, efficient performance.
Built to Withstand Any Climate
Thanks to its smart ball-and-socket design, the wood staves expand and contract with temperature changes without compromising the tight seal. No cracking, no splitting — just a solid sauna that stands strong season after season.
With less unused space (imagine a circle inside a square), the cube design lets the heater do its job faster and more efficiently. In a square sauna, the heat gets trapped at the ceiling. In a cube sauna, the heat is pushed back down the curved sides and into the sauna as new heat rises from the heater.
REQUIRES NO MAINTENANCE
Barrel saunas naturally shed water and, due to their structural integrity, can handle a substantial snow load. The polymer support cradles let you put the barrel on any flat surface, and the Thermowood is naturally resistant to water and insects.
SAVES ENERGY
Because there is less unused airspace to heat, less energy is required to heat the room. The thick staves are excellent insulators, and the exterior of the sauna will remain cool to the touch.
ACCOMMODATES TEMPERATURE FLUX
The ball-and-socket assembly of a cube sauna lets the wood expand and contract within the steel bands, creating a tight seal that won’t shatter.
With an array of control options to choose from, Harvia heaters make your sauna experience customisable. From mechanical controls that are traditional yet reliable.

Should I consult a doctor before using a Luso Spa sauna?
Yes. It’s vital to stay hydrated and use the sauna responsibly. If you have any underlying health conditions or are pregnant, we recommend consulting a healthcare professional before use.
Are Luso Spa saunas built sustainably?
Absolutely. Our saunas use Thermowood—100% natural, heat-treated (no chemicals), and sourced from sustainably managed Nordic Spruce forests. This material is more durable, stable, and eco-friendly than conventional timber. Shingles on the roof enhance insulation and protect against the elements.
Why do Luso Spa saunas use Thermowood?
Thermowood undergoes high-temperature treatment (around 200–220 °C in oxygen-limited environments), altering its properties to deliver:
Superior durability and stability
Resistance to decay and fire
Enhanced visual appeal
Eco-friendly credentials due to chemical-free processing
What are the benefits of roof shingles for outdoor saunas?
Roof shingles on Luso Spa saunas provide:
Protection from rain, snow, and harsh weather
Additional insulation to maintain interior warmth
Aesthetic enhancement that complements outdoor spaces
Potential increase in property value
What types of sauna designs do Luso Spas offer?
We offer two distinct designs:
Barrel Saunas: Known for quick heating, efficient heat distribution, energy savings, structural integrity, low maintenance, and high comfort.
Cube Saunas: Offer high heat and humidity, enhancing circulation, muscle relaxation, toxin elimination through sweat, and respiratory relief from congestion.
Which heating options are available?
Luso Spas supports two heating options—electric heaters and wood-burning stoves, both recommended to be from the trusted Harvia brand.
What warranties do Luso Spa saunas come with?
We offer a competitive warranty:
5-year warranty on the sauna itself
2-year warranty on the Harvia heater (terms and conditions apply)
How long should I use the sauna, and how often?
We recommend:
Traditional (dry/wet) sauna sessions capped at 20 minutes
Infrared sauna sessions can be longer due to gentler heat
2–3 sessions per week is ideal to experience full benefits; if using once a week, consider three back-to-back sessions. Daily use is possible with reduced duration to avoid overexposure
When should I avoid using a sauna?
Avoid sauna use if you:
Feel weak, are sick, or have a compromised immune system
Have open wounds or sunburn
Are pregnant, intoxicated, or have a heart condition
Using a sauna under these conditions may pose health risks.
