PROSAUNAS Thermo-Radiata Pine 1×2 SI Inside Corner Trim

Inside corners are where a dark room proves it was planned as a system. This Thermo-Radiata Pine SI profile covers the joint between two cladded walls with a clean matching line. Its 0.55 by 1.18-inch profile stays slim, while the deep color keeps the corner from flashing pale wood. The look is closest to Thermo-Magnolia, with subtle pine grain that reads beautifully under indirect light. The result feels calm and complete.

Four corners can decide whether the room feels custom or almost finished.

This 1×2 SI inside corner trim is shaped for the 90-degree joint where two cladded walls meet. At 0.55 inches thick by 1.18 inches wide, it covers the board ends without putting a heavy border around the room.

Let the corner disappear

Thermo-Radiata Pine brings a deep brown color comparable to Thermo-Magnolia. The grain stays quiet in soft light, which is exactly what you want at an inside corner. Concealed backrest and bench lighting can keep the joint in shadow while giving the wall surface a warm glow.

PLAN THE WHOLE SAUNA

The room and heater still have to work as one system.

Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
