How to Prepare Your Outdoor Sauna for Minneapolis' Summer
Posted on 29 May 2026
With summer rapidly approaching, Minneapolis homeowners are looking to spend more and more time outdoors. While outdoor home saunas are usually associated with being a hot escape during the winter, they are just as useful in the summer months. As the seasons change, your sauna may require some preparation and maintenance before summer starts. If you own a barrel sauna, proper maintenance and seasonal adjustments can help protect its performance, comfort, and longevity. If you’ve sourced your sauna from a reputable sauna company in Minneapolis, then maintenance shouldn’t be too time-consuming. Browse SaunaFin’s outdoor saunas online today!
Here are some tips for preparing your outdoor sauna for summer.
Inspect for Winter Wear and Weather Damage
The natural first step is to inspect your sauna for any winter damage. Take your time to look out for any cracks, warping, rotting, mold or loose boards that could’ve occurred during winter. Do not forget to examine your doors, roof and windows for deterioration.
Soil can also shift during freeze-thaw cycles during winter, so you should also assess the base of your sauna to ensure that the ground is level and that your sauna is stable.
Deep Cleaning to Set Your Home Sauna Up for Summer Success
It is highly recommended that you deep clean your sauna before summer in order to prevent musty odours or premature deterioration.
- Refresh the Interior Surfaces: Clean the benches, backrests, floors and walls with a mild soap and towel to remove any dirt, dust or debris. Avoid harsh cleaning products in order to preserve the wood quality.
- Vacuum or Sweep: If there is any foliage or large accumulation of debris, sweep or vacuum it off the floor.
- Air Out Your Sauna: If you notice any lingering musty odours after winter, leave your sauna door open to air it out after cleaning. This will not only help dry out the inside, but it will also restore the air quality inside.
Prepare Ventilation and Temperature Control Systems
Many barrel sauna owners forget to inspect their sauna vent after winter, even though this is a hotspot for dust accumulation. Ensure that your vents are clear and functional, as this is crucial for airflow and temperature control.
After winter, you should also test your sauna heater to ensure that it is operating as intended. Inspect your heater for any wear and tear, along with the electrical connection point, before turning it on to ensure that it is working properly.
Sealing Your Sauna
Sealing your home sauna is optional but can be useful to prevent your wood from drying out or cracking during hot summers. Quality cedar barrel saunas don’t always require sealing because of the naturally occurring oils in this wood. However, if you choose to seal your outdoor sauna, ensure that you use a sauna-safe sealant designed for wood.
