Shipping & Delivery

The Round Cube Relax is delivered via scheduled premium freight service directly to your residence, project site, or installation location for a seamless delivery experience. Each sauna is carefully prepared and professionally packaged to ensure it arrives securely and in pristine condition.

When inventory is available, most orders ship within approximately 3–5 business days. Due to the limited production nature and international demand for the award-winning Round Cube Collection, select configurations and upgrades may occasionally require extended lead times.

If a unit is temporarily out of stock, upcoming production shipments may require an additional 6–8 weeks or longer, depending on manufacturing schedules and overseas transit availability.

For time-sensitive projects, custom builds, or architectural installations, we recommend contacting our team prior to purchase to confirm current inventory, production availability, and estimated delivery timelines for your preferred configuration.

Each sauna arrives as a complete premium DIY sauna kit and includes all essential structural components, roofing materials, hardware, and finishing details required for installation.
