Frequently Asked Questions

Yes. The MW Series is designed primarily for outdoor installation. The ThermoWood construction, bituminous roofing system, and exterior hardware are built for year-round exposure in typical U.S. climates. Proper foundation and drainage are critical to long-term performance.
Yes, with specific modifications. Roofing tiles, metal roof straps, and rear exterior siding elements must be omitted. An electric heater must be used — wood-burning heaters are not permitted indoors. Indoor installations must comply with all local building and electrical codes.
No traditional insulation is used. The walls are constructed from thick ThermoWood profiles, which offer improved dimensional stability and heat retention compared to untreated softwood. These saunas are designed for traditional high-heat sauna performance, not infrared-style low-heat operation.
With proper heater sizing: MW12 approximately 25–35 minutes, MW16 approximately 30–40 minutes, MW20 approximately 35–45 minutes. Heat-up time varies depending on outdoor temperature, heater model, and ventilation settings.
A 170–200°F operating range is typical with recommended heater installation. Maximum achievable temperature depends on heater model and local electrical supply. Always follow heater manufacturer guidelines.
We recommend oiling the exterior every 2–3 years. If left untreated, the exterior will naturally develop a grey patina over time — this does not affect durability. If a warmer wood tone is preferred, exterior oil may be applied every 2–3 years.
Minor surface checking is normal in solid wood products exposed to temperature fluctuation. ThermoWood significantly reduces warping, twisting, resin leakage, and major structural cracking. Small cosmetic cracks do not affect performance or warranty.
Improper foundation. The sauna must sit on a level, stable, non-shifting surface. Uneven foundations can cause door alignment issues, structural stress, and premature wear. Electrical installation errors are the second most common issue.
Yes. Because the sauna is assembled from modular components, it can be disassembled and relocated if necessary. Full disassembly is required, electrical must be disconnected by a licensed electrician, and care must be taken not to damage glass panels.
At least 12 inches is recommended on rear and sides for airflow and service access. Heater clearances must follow manufacturer requirements. Indoor installations must comply with local fire code.
Yes. When using compatible Harvia electric heaters with Wi-Fi control modules, remote scheduling and app-based control is possible. Availability depends on heater model selection.
With proper installation and maintenance, 20+ years of structural use is expected. The MW Series is positioned as a long-life investment, not a temporary kit structure.
Yes, for light to moderate commercial environments such as boutique wellness studios, recovery clinics, gyms, and short-term rental properties. For heavy commercial environments, usage scheduling and routine inspection are recommended.
Flat-packed in an OSB crate with skid, via LTL curbside delivery with liftgate. The receiver is responsible for final placement and inspection at delivery. Freight damage rate is historically under 3%.
Damage must be noted at delivery and claims submitted within 5 days. Replacement components can be shipped individually. Prompt reporting ensures faster resolution.
The 5-year structural warranty applies under normal, properly installed use. For commercial environments, usage intensity may affect coverage interpretation. Dealers should consult Mande Spa USA for clarification on specific high-volume applications.
Wood-burning heaters are compatible with MW20 for outdoor use only. They are not permitted indoors, in enclosed garage environments, or in spaces without proper chimney clearance.
No plumbing connection is required. Water used during sauna sessions evaporates through ventilation. Proper drainage around the foundation is still necessary for outdoor installations.
