IR12 is already identified as an Indoor Infrared Sauna, so its real product images can be used to inspect the visible arrangement of emitter surfaces relative to the compact seating area.
Review the visible side and wall relationships, bench and floor context, and the way the photographed hardware sits around the seating zone. These observations help with layout review, but confirm emitter count, material, wavelength, spectrum, output per panel, wiring topology, heat distribution or therapeutic coverage.
Use the 1300 × 1200 × 1900 mm overall reference and W1190 × D1165 × H1710 mm internal reference for early comparison. The final approved drawing and quoted Infrared hardware/electrical configuration should define the actual order.
