Common Questions Answered
These are common questions customers ask to decide on the MW20 sauna.
Mande Spa ships within 5 days. Please allow an additional 7 business days for curbside delivery. Scheduled deliveries by appointment, Monday - Friday during business hours. Products delivered curbside via our logistics partner with liftgate service. Inside delivery available upon request (white glove placement not offered). Curbside delivery is standard; moving to the final site is the receiver’s responsibility. Tracking numbers provided for all shipments.
Yes — we provide third‑party financing options that allow monthly payments on approved applications. Terms and eligibility vary by provider; you can view financing choices at checkout or contact our sales team for a custom quote.
We recommend a level, non‑compressible foundation and proper clearances, especially when selecting the woodburner heater. All electric heaters must be installed by a licensed electrician to meet local codes; our installation guide outlines the exact safety and clearance specifications.
ThermoWood® is thermally modified to resist moisture and dimensional movement, making it highly durable in outdoor conditions. We back the build with a 5‑year warranty and provide care guidance so the sauna remains effective and attractive for many years.
Routine maintenance is light: wipe benches, brush floors, and check seals periodically. For woodburner models inspect the chimney yearly and for electric heaters follow the Harvia maintenance checklist included with your unit.
We offer Harvia electric heaters (6.0kW, 8.0kW) with optional Wi‑Fi controls, plus the Harvia M3 woodburner with full chimney. Selection depends on your electrical capacity, desired heat profile, and whether you prefer wood‑fired ambiance; our comparison table and sales team can help you decide.
ThermoWood® is modified by heat without chemicals, improving moisture resistance and longevity compared with untreated wood. It requires less chemical treatment than many alternatives, making it a more sustainable and low‑maintenance choice for outdoor saunas.
The MW20 weighs about 1565 lbs and measures approximately 78.7" × 77.6" × 83.5", so we recommend a level concrete pad or compacted gravel base. Allow adequate access for delivery, ventilation, and chimney routing if you select the woodburner; we supply detailed site‑prep guides after purchase.
