The SUPD-03: 4-Person Finnish Sauna with a Showpiece Front
The SUPD-03 is a 4-person traditional sauna designed around the moment that sells a premium space: full-glass front, warm wood, and a starry-sky LED ceiling overhead. Its 6000W traditional stove with sauna stones delivers authentic Finnish steam — 70–90°C air temperature, water ladled onto stones for that sharp, clean löyly. At 1800×1800×2000mm it is sized for small spas, boutique hotels, and homeowners who want a showpiece rather than a corner unit.
Who it’s for
- Spa & resort buyers staging an Instagram-worthy sauna suite
- Glamping / boutique hotel projects where the sauna is a marketed amenity
- Private homeowners building a dedicated wellness room
How it compares
SUPD-03 vs SUPD-04: Both are 4-person full-glass traditional saunas (1800×1800×2000mm, 6000/6100W). The differentiator is ceiling mood lighting: SUPD-03 = starry-sky LED (spa/wellness ambiance), SUPD-04 = warm cove lighting (hotel lounge feel). Sell by ambience, not by spec sheet.
SUPD-03 vs SUPH-02: SUPH-02 is a 5-person traditional sauna (2150×2000×2100mm, 8000W) without the glass front. Choose SUPD-03 for open, light-filled rooms; SUPH-02 for higher capacity in enclosed cabins.
