Our Take
The Rainelle is a 4-person indoor sauna with two full-length, multi-level benches and a 6 kW heater. Tongue-and-groove construction with pre-assembled wall sections. Three lumber options: rustic fir, rustic cedar, or clear cedar. Four door styles. You pick the heater. Assembly takes two people and basic tools. This is a permanent installation that turns a spare room corner into a Finnish sauna.
At $4,933, the Almost Heaven Rainelle 4-Person Indoor Sauna sits in the mid-range of our sauna rankings. Real traditional sauna, indoors, and pre-assembled sections cut build time.
How does it compare? The Almost Heaven Auburn 2-3 Person Indoor Sauna ($4,878 · our take) fits spaces the rainelle can't, while The Dundalk Leisurecraft Georgian Cabin Sauna ($7,009 · our take) cedar is naturally rot and insect resistant. See our full comparison for a detailed breakdown.
However, it's worth noting that permanent installation, needs dedicated space, and requires 240v circuit and ventilation planning. Not sure if this is the right fit? Our 2-minute quiz can help you narrow it down.
