SaunaLife Model E7W
The SaunaLife Model E7W is the windowed 4-person ERGO barrel — the mid-size sweet spot in the series, offering the same panoramic half-moon rear window as the E8W in a shorter, more yard-friendly footprint. At 71" long and 81" in exterior diameter, the E7W fits comfortably in backyards where the full 87" E8 family would feel oversized, while still accommodating four bathers in full ERGO comfort: the 81" diameter gives the same 6'5" interior standing height, the same generously arched bench configuration with 1.1" × 3.5" wide knot-free Thermo-Aspen seating, and the same arched backrest delivering genuine lumbar support across all body sizes.
The half-moon rear window is the E7W's defining feature. Filled with 5/16" tempered bronze glass, it draws natural light through the back wall and opens the sauna to a view of whatever lies behind the barrel — garden, trees, water, open sky — turning what would otherwise be a closed stave end cap into a living picture frame. The effect on the interior ambiance is significant: the sauna feels brighter, more connected to the outdoors, and more spacious than its 63" interior length would suggest. For four-person households who want nature immersion without stepping up to the E8-family footprint, the E7W delivers exactly that.
The structural spec is standard ERGO throughout: 1.65" full-length Thermo-Spruce staves lasting up to 2× longer than cedar, heavy-duty stainless steel barrel bands at 1-7/8" wide and 1/8" thick, black shingle roof kit with side-mounted drip edges, dual floor drains, natural Spruce cradles and fascia in an unpainted finish, and the standard Wi-Fi LED lightbar system. E Sconce+ and E MOOD chromotherapy upgrades available. DIY 1-day, 2-person assembly. Heater sold separately — required for operation.
