We check with our suppliers to see if your order is in stock and ready to ship right away. The majority of pre-made saunas and accessories are available for shipping right away, however custom saunas take longer.

Your order will ship as soon as your order is accepted and your money has been received (unless it is a special case sauna as mentioned above). On the day your order ships, we will email the tracking information to the email address you provided during checkout.

All saunas are delivered in a 53-foot semi-truck with a single driver, who will unload the pallet to your curbside or driveway only.

Due to the unique nature of many of our saunas, many may require at least 3–4 weeks before they are ready to ship; if the sauna is especially specialized or personalized, this time frame may be extended.

Sauna accessories and readymade saunas (like infrared) are the exceptions, and if they are in stock, they should be delivered 7-10 business days after payment is received.

Shipping of just accessories will have a $55.00 flat shipping fee
