Your Complete
Sauna Buyer's Guide

Buying an outdoor sauna is a significant investment. We want you to feel completely prepared — from site selection to heater choice to electrical requirements. Here is everything you need to know.

1. Choosing the Right Location

The placement of your sauna matters more than most people realize. Think about proximity to your home — you will be walking to and from the sauna in all weather conditions, including Minnesota winters. A shorter walk in the cold is always better.

Consider privacy, views, and how the sauna will look from your home and yard. A sauna tucked into a natural setting with trees or landscaping around it creates a much more immersive experience than one placed in the middle of an open yard.

Also think about electrical access. Your sauna requires a 240V dedicated circuit run by a licensed electrician. The closer your sauna is to your home's electrical panel, the simpler and less expensive that run will be.

Pro tip: Walk the path from your back door to your proposed sauna location in your imagination during a January evening. That mental test will tell you a lot about whether the location is right.

2. Site Preparation & Base

Your sauna needs a stable, level base to sit on. This is your responsibility to prepare before delivery, and getting it right makes a significant difference in the long-term performance and appearance of your sauna.

The most common and recommended base is a compacted Class V gravel pad, typically 4 to 6 inches deep. All topsoil and organic material should be removed first — you do not want your sauna sitting on anything that will settle, shift, or promote decay over time. A concrete pad or existing patio is also an excellent option if you have one available.

Gravel Pad

Most popular option. 4–6" of compacted Class V gravel on a cleared, level base. Cost effective, drains well, easy to install yourself or hire out.

Concrete Pad

Premium option. Level, stable, and permanent. If you already have a suitable concrete area your sauna can be placed directly on it.

Deck Blocks

Suitable for relatively flat ground. Tundra Saunas sit on pressure treated skids that can rest on properly leveled deck blocks.

Existing Patio

If you have a level patio of pavers or concrete, this can work well. Confirm it is level and can support the weight of the sauna.

3. Sizing — How Big Do You Need?

Our standard Frontier model has a 6×6 exterior footprint — roughly 5×5 on the interior. This is the right size for one to three people comfortably, with upper and lower bench seating along the back wall.

If you regularly entertain or want more space, we can build custom sizes. Larger saunas take longer to heat and require more electrical capacity, but they also accommodate more people and create a more social experience.

  • 1–2 people regularly: 6×6 is perfect
  • 3–4 people regularly: consider 6×8 or 8×8
  • 5+ people or commercial use: 8×10 or larger, contact us for a custom quote
  • Custom sizing is available — contact us to discuss your needs

4. Electric vs. Wood-Fired Heater

This is one of the most common questions we get and the answer depends on how you want to use your sauna and what your property allows.

Electric Heater

Our standard — Harvia KIP60B 6kW. Simple push-button control, heats up in 30–45 minutes, no wood to source or manage. Requires a 240V dedicated circuit. Best for frequent, convenient use.

Wood-Fired Heater

Traditional Finnish experience. Requires sourcing and storing firewood, longer heat-up time, and a chimney assembly. No electrical hookup needed for the heater itself. Best for the authentic experience and off-grid properties.

Our recommendation: For most homeowners in the Twin Cities and surrounding areas, electric is the right choice. It is convenient, consistent, and easy to use daily. Wood-fired is a wonderful experience but requires more commitment and planning.

5. Electrical Requirements

All electric Tundra Saunas require a 240V dedicated circuit installed by a licensed electrician. This is not included in the sauna price and is the responsibility of the buyer to arrange.

Your electrician will run a dedicated circuit from your home's electrical panel to the sauna location. The sauna arrives pre-wired with the wire exiting the exterior wall — your electrician simply connects it to the panel and installs the appropriate breaker.

  • Dedicated 240V circuit required — do not share with other appliances
  • 30A two-pole GFCI breaker recommended — confirm with your electrician
  • Wire gauge: 10/2 or 10/3 for a 30A circuit
  • Separate 120V circuit for lighting — 15A single pole breaker
  • All electrical work must be performed by a licensed electrician per local code
  • Permit requirements vary by municipality — check with your local building department
Not sure what to tell your electrician? We will walk you through exactly what information to provide when requesting a quote — circuit requirements, wire gauge, breaker specs, and what to expect from the installation process. Every situation is different and we are happy to help you prepare. Just reach out.

6. Color & Exterior Finish

Your sauna's exterior color is one of the most visible decisions you will make. Tundra Saunas are finished with Pittsburgh Paramount exterior satin paint over LP SmartSide engineered wood — a durable, weather-resistant combination built for Minnesota's freeze-thaw cycles.

We offer several standard colors and can accommodate custom colors for an additional fee. Our standard colors are selected to complement natural outdoor settings and look great year-round.

  • Standard colors available — contact us to see current options
  • Darker colors like charcoal tend to photograph beautifully and complement natural settings
  • All exteriors are painted with premium exterior satin paint rated for harsh climates

7. Add-Ons & Customization

The Frontier is our standard model but we are happy to discuss customization. Common add-ons and upgrades include:

  • Cedar front deck — adds a landing platform in front of the door, great for stepping out into the cold
  • Custom sizing — larger or different footprint available, contact for quote
  • Wood-fired heater — swap electric for a wood stove, custom chimney assembly included
  • Custom exterior color — any color you want for an additional fee
  • Upgraded door hardware — different handle or locking mechanism options
Not sure what you need? Reach out and we will walk you through the options. Our goal is to build you exactly the sauna you want — not upsell you on things you don't need.

8. Delivery & Placement

Tundra Saunas are built at our shop in Ham Lake, MN and delivered to your property by a professional third-party moving company. Delivery and placement is quoted separately based on your location and site conditions.

Before scheduling delivery, make sure your site is prepared and level. Also consider the access route — the moving equipment needs adequate clearance to reach your sauna's final location. Let us know about any tight gates, low overhead obstacles, or steep grades during the quoting process so we can plan accordingly.

  • Site must be prepared and level before delivery
  • Delivery quoted separately based on location
  • Inform us of any access challenges — tight spaces, low clearances, steep grades
  • Pickup available at our Ham Lake location if you prefer to arrange your own transport
We are here to help with the logistics. We can assist you in gathering the information needed to get a third-party moving company quote on your behalf — access route details, sauna dimensions, weight, and placement requirements. Every property is different. You are also welcome to source and arrange your own transport and placement company. Either way we will make sure you have everything you need.

9. Permits & Local Requirements

Permit requirements for outdoor saunas vary significantly by municipality. In general, smaller structures on skid foundations that are not permanently attached to the ground are often treated as moveable structures and may not require a permit — but this varies by location and you should always check with your local building department before installation.

Electric saunas almost always require an electrical permit pulled by your licensed electrician. Your electrician will handle this as part of their work.

Our advice: Call your city or county building department and describe what you are installing. A 6×6 outdoor sauna on skids with a 240V electrical hookup. They will tell you exactly what is required in your jurisdiction.

10. Maintenance & Care

A Tundra Sauna is built to be low maintenance, but a small amount of regular care will keep it performing and looking great for decades.

  • Exterior: inspect paint annually, touch up any chips or cracks to prevent moisture intrusion
  • Interior: wipe down cedar walls and benches periodically with a dry or slightly damp cloth
  • Ventilate after each use — leave door slightly ajar to allow moisture to escape and interior to dry
  • Heater stones: replace sauna stones every 1–2 years or when they begin to crack or crumble
  • Check electrical connections annually — have your electrician inspect if you notice any issues
  • Cedar decking: apply a cedar oil or sealant annually to maintain appearance and longevity
