This interior design of Sauna has become an important part of the Home SPA in the private residence. The project provides a comprehensive spa area in which there is a swimming pool, hammam, sauna, massage and fitness room. The sauna interior project is designed to give both sensory and aesthetic pleasure. In the sauna interior, the ceiling, walls, and floor are finished by natural wood to bring its traditional unicity as a kind of unity with the nature experience. Moreover, as a basis, we have taken the natural woods of valuable species. Thus, this high-quality sauna gives an interesting visual appearance due to a fusion of the natural and modern up-to-date materials.
