My own sauna from off-the-shelf components.
Benches and walls are aspen, that doesn't feel hot. Wide timber gives a modern look.
As I have a small bathroom, light colors and a clear glass wall make it more spacious.
Sauna stow has only 30 mm clearance to avoid accidents.
Continuous LED stripe below the bench give a tranquil atmosphere.
