Frequently Asked Questions
Can I speak to someone before I place an order?
We encourage it. Investing in high-ticket wellness architecture is a major decision. Reach our concierge team directly at (888) 898-1024 or support@therecoverystate.com (Monday–Friday, 9 AM – 5 PM PST) to verify dimensions, lead times, or electrical compatibility.
Where should I install my sauna?
Most units can be installed indoors on any flat, level surface capable of supporting the weight (such as tile, concrete, or reinforced wood). For exterior placement on decks or patios, select our outdoor-rated and barrel models engineered to withstand the elements.
What electrical setup is required for my sauna?
The SaunaBox® Solara (1-Person) is our dedicated plug-and-play system, operating safely on a standard dedicated 110V/120V household outlet. All other sauna models—including the SaunaBox® Forge, ALEKO, and Dundalk Leisurecraft systems—are high-performance thermal units requiring a dedicated 220V/240V circuit installed by a certified electrician. Always check the Specifications tab above for this model’s exact breaker amperage and voltage needs.
Do you offer free shipping and freight delivery?
Yes, we offer complimentary, fully insured freight shipping on all sauna systems. Oversized units ship via dedicated freight carriers equipped with hydraulic liftgates, delivering securely curbside or to your driveway with scheduled delivery appointments included.
