Indoor vs. Outdoor Sauna: Which One Fits Your Home?

Home saunas have become one of the most popular backyard and home wellness additions — but "sauna" covers a range of very different setups. Here's how to think through indoor versus outdoor options before you buy.

Indoor Wood Sauna Rooms

An indoor sauna room is built to fit inside an existing room — a basement, bathroom, or spare room — using the house's existing structure rather than requiring outdoor construction or a foundation. This is usually the simpler installation route and keeps the sauna accessible year-round regardless of weather, which matters if you're planning to use it regularly rather than occasionally.

Outdoor Saunas: Cube vs. A-Frame

Outdoor saunas stand alone in the yard, which means more flexibility on placement but also more exposure to the elements. Rounded cube designs offer a compact footprint and a modern look, while traditional A-frame saunas have a more classic cabin-style silhouette and often slightly more interior headroom. Both styles come in natural wood or darker finished options, depending on whether you want the sauna to blend into greenery or stand out as a feature.

What to Consider Before Choosing

• Frequency of use. If you plan to use it several times a week, proximity to the house — or an indoor option — usually wins out over a standalone yard structure.
• Available space. Outdoor saunas need a level, accessible spot with room to open the door fully and, ideally, some weather protection like an overhang or gazebo cover.
• Climate. In colder or wetter climates, outdoor saunas need more attention to sealing, ventilation, and seasonal upkeep than an indoor room does.

Either Way, It's a Long-Term Addition

A well-built sauna, indoor or outdoor, is meant to last for years rather than one season — which makes it worth taking the time to match the style to how, and how often, you'll actually use it. Browse our sauna collection to compare indoor and outdoor options.
