- Quote-Based Ordering Recommended: Due to the size, customization, freight coordination, and placement requirements of Thermasol sauna products, we strongly recommend placing orders through a custom quote consultation rather than standard online checkout.

- Site Preparation: Foundation work, electrical preparation, drainage planning, and access path confirmation should be completed before delivery whenever possible.
