Outdoor Sauna Maintenance

Caring for your outdoor sauna from Redwood Outdoors is a breeze. Use this page to learn about sauna care before you buy or as a quick review when you’re already up and running.

General Maintenance is Minimal

Clean the interior regularly.

Don’t use chemicals inside your sauna! They can damage the wood and you’ll be breathing them in when it heats up. Instead, give it a quick sweep or run the vacuum in it when it needs a touchup. If you start to notice stains from dirt or perspiration and general wear, use warm water and gently scrub the spots or invest in a low-pressure washer and use a wide-pattern nozzle. You can also buff away stubborn stains and scuffs with fine-grit sandpaper.

Replace your sauna stones if they crack or split.

Sauna stones can last indefinitely, but fluctuations in temperature will cause them to crack or break. If this happens to yours, you’ll need to replace them with rocks that are safe, hold heat well, and are resilient. The best way to take the guesswork out of this is to come back to us for more.

Treat the Exterior as Desired

Wash the exterior as needed.

You can hose it off or use a low-pressure washer to remove debris and stains.

Address water seepage promptly.

A small amount of water seeping into the sauna during a storm isn’t going to hurt it, but if you notice a substantial amount, it means you need to add more staves under the bands. When the inside and outside of the sauna is dry, take apart the top portion of it and rebuild it with additional staves. Bear in mind, if you’re in a dry climate, the wood will shrink, so you may have to add more bands later. Check the tension of the bands every few months so you can catch problems before they start. On the other hand, those in humid climates can expect the wood to swell some, which will create a tighter seal.

Stain it if you don’t like a weathered look.

Again, you should NEVER apply anything to the inside of the sauna. However, you can stain (NOT paint or varnish) the exterior if you like. Although we recommend that you choose a stain with UV protection, the rest is up to you. If you’re unsure which is best, talk to someone at your local home improvement store who can give you region-specific recommendations.

Apply a new coat of stain as needed.

A good rule of thumb is to plan to restain your sauna annually, but you may need to do it more or less often depending on how much sun it gets.
