Add a sauna window to your project. Frame a view of your outdoor scene, or let light in from an adjacent room. Our windows are set in a 2×6 cedar frame that is built to your rough opening size. Tempered glass is recommended for indoors, in clear, bronzed, or obscure options. Thermopane is recommended for outdoors, for extra insulation. Standard sizes are 18×24 and 24×24, and custom sizes can be made to order.
