The SaunaLife GL4 is a four-person outdoor sauna kit built to last from thick thermally modified Nordic spruce. Its contemporary design features a full bronze tempered-glass front, integrated porch with dotless LED eaves and contrasting black trim. Two tiers of knot-free thermo-hardwood benches and indirect LED lighting create a comfortable sanctuary for up to four bathers. The kit includes all materials, pre-cut boards and intuitive instructions; two people can assemble it in about two days.
