Outdoor saunas come in three main configurations: barrel, cabin, and pod. They look different, heat differently, and suit different situations. Here's how to pick.
A barrel sauna is exactly what it sounds like — a cylindrical barrel shape, typically 6-8 feet long, made from cedar or thermally treated wood. The curved walls are the key feature. They reduce the interior air volume compared to a square cabin of the same size, which means faster heat-up times and lower energy consumption.
A standard 2-4 person barrel sauna heats to 160-180°F in 30-45 minutes with an electric heater, or 20-30 minutes with a well-tended wood-burning stove.
Barrel saunas are the most popular outdoor choice for homeowners because they're relatively compact, aesthetically clean, and easier to assemble than full cabin builds. Most arrive partially assembled on a freight pallet and go up in 3-5 hours with two people and basic tools.
Check our barrel saunas guide for a full comparison of Dundalk and SaunaLife models.
Dundalk LeisureCraft — Built in Ontario, Canada using Eastern White Cedar. Three main models: Luna (2-4 person), Harmony (4-6 person with porch), Georgian (6-8 person with change room). Wood-burning or electric heater options available. Free shipping.
SaunaLife — Uses thermally treated wood for superior weather resistance. Models E7 (4 person) and E8 (6 person) come with a Harvia electric heater included. Slightly more weather-resistant than cedar over the long term.
Cabin saunas are the traditional house-shaped design — four walls, a roof, benches on two or three levels. More interior space than a barrel for the same footprint. A cabin sauna feels more like a room and less like a feature piece.
These are the right choice when you want to seat 6+ people comfortably or when you want to add a changing room or antechamber. Cabin saunas also accept larger heaters, which matters if you're doing traditional Finnish sauna with high temperatures and lots of steam.
Finlandia — Pre-cut cabin sauna room kits from a US company that's been making them since 1964. Clear Western Red Cedar, available in sizes from 4x4 up to 8x12. You supply the frame, they supply everything else.
Auroom — Estonian-designed cabin and pod saunas with a distinctly modern aesthetic. Auroom saunas look like they belong in an architecture magazine. If the visual matters as much as the function, Auroom is worth looking at.
Pod saunas are a newer category — oval or teardrop-shaped enclosures that split the difference between barrel and cabin. The rounded shape is structurally strong, visually striking, and efficient to heat. They tend to be more expensive than barrel saunas for comparable capacity.
Auroom makes several pod-style models. They're not for everyone on price, but if you want the most visually distinctive outdoor sauna available, pod saunas deliver it.
This is the most common question when buying an outdoor sauna.
Electric heaters are easier. Plug in, set the temperature, walk away. You can preheat from your phone with a smart heater. No firewood, no ash, no carbon monoxide risk.
Wood-burning heaters are an experience. Building the fire, feeding it, smelling the wood smoke — it's part of the ritual for a lot of sauna enthusiasts. The heat from a wood stove also has a different character: dryer and more intense in waves rather than steady. And you don't need an electrical connection, which matters if you're siting the sauna away from your house.

Every outdoor sauna needs a level, stable base. Options in order of ease:
Compacted gravel pad: 4-6 inches of crushed stone, well-compacted and level. Water drains through it. Simple and effective. Works for almost all barrel and cabin saunas.
Concrete deck blocks: Set 6-8 blocks level and use them as the foundation for the floor frame. More adjustable than a poured pad. Good option for uneven ground.
Concrete slab: Most permanent option. Required for very heavy cabin-style builds. Overkill for most barrel saunas.
The key is keeping the sauna floor off direct contact with the ground so water doesn't pool under it.
All outdoor saunas we sell ship via freight. A delivery truck drops the pallet at your driveway — you need to have a few people available to move the pieces. The barrel sauna assembly is designed for two people with basic tools. Cabin kits take a bit longer but are still a realistic weekend project.
Browse our full outdoor saunas collection to filter by type, size, and brand. Free shipping on every order. Many models are HSA/FSA eligible.
This varies by municipality. In most areas, a freestanding accessory structure under a certain square footage (often 200 sq ft) doesn't require a permit. An electrical permit is usually required for the heater wiring. Check with your local building department before you buy.
A quality cedar or thermally treated wood sauna maintained properly should last 20-30 years outdoors. Treat the exterior wood with a UV protectant every 1-2 years. Keep the roof clear of debris and standing water. The heater has a separate lifespan — electric heaters typically last 10-15 years.
The Dundalk Luna barrel sauna has a 6-foot barrel diameter and is about 7.5 feet long including the door. Add 2-3 feet of clearance on all sides for maintenance access and ventilation. So realistically, a 10 x 12 foot clear area handles a small barrel sauna comfortably.
