Frequently asked questions
We know investing in a sauna comes with a lot of important decisions. To make things easier, we’ve answered some of the most common questions we get about outdoor saunas, installation, and what to expect when working with Northern Steam. If you don’t see your question here, feel free to send us a message—we’re happy to help.
Do I need a permit for an outdoor sauna?
In most Minnesota counties, outdoor saunas do not require a permit if they’re delivered as a fully self-contained structure with no foundation. However, electrical hookups or decks may require permits depending on your city. When you contact us, we can help you confirm exactly what’s needed in your area.
Do I need an electrician to install a sauna?
If you choose an electric stove, you will need a licensed electrician to run the appropriate power to the unit. Wood-fired saunas typically do not require electrical work, unless you add lighting or other powered features. We can guide you through what’s needed during your consultation.
How big should an outdoor sauna be for 4 people?
A comfortable 4-person sauna is typically 6×8 or 7×8 depending on bench layout and stove choice. If you’re unsure what size fits your property or group size, include that in your message—we’ll recommend the ideal setup.
How much does it cost to put in an outdoor sauna?
Our fully built outdoor saunas start around $14,000–$18,000 depending on size, stove type, and finish selections. Custom builds vary based on design complexity. When you submit the form, we’ll provide a clear, itemized quote with no surprises.
Are outdoor saunas hard to maintain?
Not at all. Our saunas are built with cedar interiors, premium exterior materials, and proper ventilation, making them low-maintenance. Most owners only need occasional cleaning and simple care of the stove. We’ll walk you through maintenance expectations when you reach out.
Is it safe to use a sauna every day?
For most people, yes—daily sauna use is considered safe and even beneficial when used responsibly. The key is staying hydrated and limiting sessions to a comfortable duration. While we don’t provide medical advice, we build our saunas to meet traditional Finnish standards for safe, enjoyable daily use.
