JONAS Classic in Shou Sugi Ban with Matching Feature Wall – Marbella, Spain

One sauna, one matching wall, one architectural whole.

On a hillside in Marbella, on Spain’s Costa del Sol, this modern white villa looks out over the coast toward the mountains. For its owners, Celsium built and installed a JONAS Classic outdoor sauna with a Shou Sugi Ban exterior, and then went one step further.

Shou Sugi Ban in the Spanish Sun

Shou Sugi Ban is the traditional Japanese technique of charring timber to protect it. The deep, textured black surface stands up to strong sun, moisture and insects, which suits the light and heat of southern Spain. Against the villa’s white walls, it creates a calm, striking contrast.

A Wall Made to Match the House

To tie the sauna into the architecture of the home, our team also installed a feature wall on the villa in the same Shou Sugi Ban timber. Sauna and wall now share one material and one finish, so the sauna reads as part of the house’s design rather than an object placed in the garden.

Inside: Light Wood and an Open View

Inside, the dark exterior of the JONAS Classic sauna gives way to a bright, warm wooden interior with tiered benches, the signature Celsium backrest and a large panoramic window that frames the Mediterranean greenery outside.

This project shows what Celsium does beyond the sauna itself: matching materials, finishes and details so that wellness becomes part of the home’s architecture.

Crafted in Europe. Built for a Better Life.
