The Sonoma 3-Person Hemlock Corner Infrared Sauna by HeatWave brings the signature Sonoma aesthetic — frosted stripe glass door and two frosted stripe side windows — to a compact corner-fit design sized for three. Its 55" × 35" footprint tucks into any room corner without intruding on living space, while the 7 carbon heaters producing 1,805 watts of steady, dry FAR infrared heat keep the 51.6" × 27.5" interior warm and comfortable for all three users up to 140°F. Running on a standard 120V / 15A circuit — the most accessible electrical requirement in the Sonoma lineup — it includes chromotherapy lighting, an oxygen ionizer, wireless audio with two built-in speakers, interior and exterior LED spotlights, a towel rack, magazine rack, and 2 cup holders. Built from solid Canadian Hemlock with tongue-and-groove joinery and outer clasps, backed by a manufacturer warranty of up to 7 years and certified to CE, CETL, RoHS, and ISO 9001 standards.
The Sonoma 3-Person Corner shares the signature Sonoma frosted stripe aesthetic — a full-length frosted stripe glass door and two frosted stripe side windows that flood the cabin with natural light while maintaining complete privacy. The 55" × 35" footprint installs flush against two adjacent walls, making it one of the most space-efficient ways to fit a 3-person home sauna into a corner space.
Seven carbon infrared heating panels deliver 1,805 watts of steady, dry FAR infrared heat throughout the 3-person cabin — up to 140°F — with no steam or moisture. Running on a standard 120V / 15A circuit, this is the most electrically accessible model in the Sonoma lineup — no special wiring or high-amperage circuit required for most homes (dedicated circuit recommended).
Solid Canadian Hemlock with tongue-and-groove joinery and outer clasps creates a warp-resistant, sturdy, and dependable structure that retains heat efficiently. Hemlock is naturally hypoallergenic and scratch-resistant, adding a clean natural finish that blends with home décor. Assembly takes approximately 45 minutes with all hardware and instructions included.
The full-spectrum chromotherapy lighting system adds color-based wellness to every session. An electronic oxygen ionizer actively purifies cabin air, with adjustable roof vents for airflow control. The wireless-connected integrated sound system streams audio through two built-in speakers without cables — creating a complete multi-sensory wellness environment for all three users.
Both are HeatWave Sonoma hemlock carbon saunas sharing the same frosted stripe glass door and side window aesthetic, tongue-and-groove + outer clasp construction, dry FAR infrared heat, and interior-only LED control panel. The key differences: the Sonoma 3-Person Corner (SA7019) has a 55" × 35" corner footprint, 7 heaters at 1,805W, runs on 120V / 15A, and seats up to 3 adults (660 lb capacity). The Sonoma 4-Person (SA7020) has a 71" × 45" straight-wall footprint, 9 heaters at 2,100W, requires a 120V / 25A dedicated circuit, and seats up to 4 adults (880 lb capacity). Choose the 3-Person Corner for a smaller corner space and standard 15A wiring; choose the 4-Person for a larger group and a straight wall with 25A circuit access.
