An interior view of a sauna or infrared therapy room, located in Dobri dial, Bulgaria, is depicted under ambient red lighting. The room's walls and ceiling are constructed from light-toned wooden planks. The back wall features two prominent vertical panels with horizontal wooden grates, behind which bright, orange-yellow heating elements are actively glowing. Beneath the upper seating bench, additional horizontal heating elements emit light. Two tiers of slatted wooden benches span the right side and rear of the room. On the upper bench, a light-colored wooden bucket containing two wooden ladles is positioned. In the lower-left foreground, a square wooden stand holds an open-top wooden receptacle filled with dark, rough sauna stones. A black digital control panel with red readouts and buttons is mounted on the upper left wall. A vertical glass panel, likely part of a door, runs from the top to the bottom of the frame, partially obscuring the view into the room. No individuals are present in the scene.
