As outdoor swimming pools begin to close for the season and the Mediterranean seawater cools down, many homeowners in Marbella start turning their attention toward indoor wellness and relaxation. In this October, we completed a beautiful thermo wood sauna project for clients who wanted a warm, luxurious retreat they could enjoy all year long.
Crafted entirely from premium thermo wood and designed with both durability and aesthetics in mind, this sauna brings Nordic spa quality to sunny southern Spain.

A thermo wood sauna offers several important benefits—especially in coastal areas like Marbella where humidity levels and temperature fluctuations can affect traditional wood.
Thermo wood is:
Because of these advantages, it was the ideal choice for every part of this project—from floors and walls to ceilings and benches.

For this project, the entire sauna interior was made from high-quality thermo wood, including:
This unified material choice ensures long-term stability, a consistent aesthetic, and superior performance in high-heat, high-humidity environments—making it perfect for Marbella’s warm climate.
Premium Extras: LED Lighting & Audio System
To elevate the experience, we integrated modern comfort features:
✔ LED Lighting Under the Benches
We used special sauna-grade LED strips specifically engineered to withstand extreme temperatures and humidity. The warm ambient glow creates a relaxing atmosphere and highlights the beautiful thermo wood grain.
✔ Built-In Audio System
For music, meditation tracks, or simple background ambience, the sauna includes high-temperature-resistant speakers designed for sauna environments. This transforms the room into an immersive wellness space.

We began by constructing a full wooden supporting structure, including:
This ensured stability and perfect alignment for all thermo wood elements.
Our trusted partner electrical company completed all wiring, including:
Everything was professionally installed to meet safety and performance standards.
To ensure maximum efficiency, we added thermal insulation to all walls and the ceiling. This helps the sauna heat up faster and maintain a stable temperature—reducing energy consumption.
We then covered all interior surfaces with thermo wood cladding and installed the thermo wood floor. The result is a clean, uniform, and luxurious Nordic look.
All surfaces were treated with Remmers HK Lasur, a high-quality wood protection product that enhances durability and helps preserve the warm tones of the thermo wood.

To heat the sauna, we supplied a heavy-duty Harvia Club heater—one of the most reliable, powerful sauna heaters on the market. It provides:
Combined with proper insulation and thermo wood construction, the Harvia heater ensures authentic Finnish sauna performance.
This project represents everything a modern thermo wood sauna should be: beautiful, durable, relaxing, and built to withstand both intense heat inside and coastal humidity outside.
Whether used for winter wellness, post-workout recovery, or evening relaxation, this Marbella sauna provides a private spa experience right at home.
