About us
OneEighty grew out of CLTEST, a company with extensive experience in producing high-quality cross-laminated timber (CLT) elements for various timber buildings.
What began in timber buildings evolved into a new approach in sauna design where CLT’s excellent properties and possibilities of CNC machining could meet design, functionality and comfort to create high-end wellness oasis that are quick to install and offer authentic everyday wellness experience.
Why CLT sauna?
CLT (Cross-Laminated Timber) is an environmental-friendly innovative building material made of natural wood and adhesive. Thanks to its natural beauty, versatility and efficiency it's a perfect material for modular saunas with minimalistic, modern architecture.
CLT elements are made by gluing layers of dried, strength-graded boards crosswise under high pressure, which gives the material an excellent dimensional stability and longevity. The pressed panels are then CNC-machined to precise dimensions with all necessary openings and joints, enabling fast and hassle-free sauna assembly.

Strong load-bearing capacity in multiple directions.
Thermal insulation properties
Good thermal performance due to wood structure and thick walls.
Dimensional stability
Reduced swelling, shrinkage, and warping.
Sustainability
Renewable material with low carbon footprint.
Lightweight
Easier transport and faster construction.
Acoustic performance
Effective sound insulation.
Aesthetic quality
Exposed timber surfaces empasize soothing beauty of natural wood.
Good fire resistance
Predictable charring rate that protects inner layers.
Hassle-free assembly
Smart design and high precision CNC-machining enable quick and effortless assembly.
Variable wood types

Why
sauna?
Regular sauna sessions do more than just help you relax. They support cardiovascular health by improving circulation and mimicking the effects of light exercise.
The heat also accelerates muscle recovery, relieves joint pain, and lowers stress hormones—paving the way for deep, restorative sleep. It is a proven routine for total body wellness.
Proven Benefits
Cardiovascular health
Raises heart rate similar to light-moderate exercise. Improves blood vessel function and circulation. Regular use is associated with lower risk of heart disease and stroke.
Muscle recovery & pain relief
Relaxes muscles and reduces stiffness. Helps relieve joint pain and arthritis symptoms. Useful after workouts for recovery.
Stress reduction & mental well-being
Activates the parasympathetic ("relaxation") nervous system. Reduces cortisol (stress hormone). Many users report improved mood and better sleep.
Blood pressure support
Repeated heat exposure can help lower resting blood pressure over time.
Sleep quality
Post-sauna body cooling helps trigger deeper sleep.
