Cube Saunas: Modern Outdoor Design for Your Backyard

Cube saunas are a modern take on the traditional outdoor sauna, built with a flat roof, clean lines, and a more contemporary look than a barrel or cabin style. They heat the same way as any other traditional sauna - with a heater and rocks - and reach the same temperatures. The difference is in the shape, the feel, and how they fit in a backyard. Our cube collection includes models from 1-2 person kits up to large 8-person cabins, made in Northern Europe and Canada, at a wide range of price points. If you're still figuring out which sauna style fits your setup, our traditional saunas collection is a good place to compare.
Wide Range of Cube Saunas

1. Compact Cube Saunas (1-2 Person)

Good for personal use or time with a partner. A smaller footprint makes these easier to place in most backyards, and most kit models go up in a weekend with two people.

2. Family-Sized Cube Saunas (4-6 Person)

Built for groups. Most 4-6 person models include two-tier bench layouts and enough interior space for the whole family. A good fit for anyone who wants to make the sauna a shared part of daily life.

3. Fully Assembled Cube Cabins

Some models arrive completely built and ready to connect to power. No assembly weekend required, but plan ahead - most fully assembled units are heavy enough to require a crane or forklift for placement on delivery day.
How to Choose Your Cube Sauna

1. Size

Think about how many people will use it regularly, not just occasionally. A 2-person model works well for personal use. A 4-6 person model is the better call for families or anyone who plans to share the experience often.

2. Kit or Fully Assembled

Most cube saunas ship as kits you put together in about two days. Others arrive fully built. The tradeoff is real - fully assembled models save you the assembly weekend but require a crane or forklift on delivery day. Worth planning for before you buy.

3. Glass and Natural Light

Some cube models have a full glass front wall. Others have a standard door with smaller windows, or no windows at all. More glass means more natural light and a better view of your yard. Less glass can give a cozier, more heat-efficient feel. Neither is better - it comes down to preference.

4. Budget

Our cube collection runs from the mid-$4,000s to well over $50,000 for a fully assembled cabin. As the price goes up, you get more interior space, higher-grade materials, and more refined finishes. There are solid options at every level.

Common questions

What is a cube sauna?
A cube sauna is a modern outdoor sauna with a flat-roofed, boxy shape and a clean architectural design. They heat using a traditional sauna heater and stones, reaching temperatures of 170-200 degrees F - the same as any other traditional sauna. The "cube" refers to the design style, not a different category of experience. Most are built for permanent outdoor installation and year-round use.
How hard are cube saunas to assemble?
Most cube sauna kits are designed for two people and take about two days to put together. You'll need a level surface - concrete pad, deck, or compacted gravel - and basic hand tools. Some higher-end models in this collection arrive fully assembled and only need to be placed and connected to power, but they're heavy enough to require a crane or forklift for unloading and placement.
Are cube saunas good for outdoor use year-round?
Yes. Cube saunas are built for permanent outdoor installation. Most use heat-treated or pressure-treated wood that resists moisture and warping better than untreated lumber, along with insulated walls and weatherproof roofing. Most buyers in snowy or rainy climates use them without issues year-round.
How are cube saunas different from barrel saunas?
The biggest practical difference is how they use interior space. Cube saunas have flat walls and full ceiling height throughout, which makes two-tier elevated bench layouts easier to build in. That means more people fit comfortably, and you can sit low for a cooler experience or high for more heat. Most barrel saunas have a curved roof that limits headroom and bench options - only a few barrel models include elevated seating. If you want to compare both styles, our traditional saunas collection includes barrel and cabin options.
