Outdoor Sauna FAQs Real answers from the Outback 365 team, covering materials, heating, installation and long-term care for outdoor sauna ownership

Most customers start by deciding on size and heater type, then narrow things down between barrel, cabin, or pod styles. Barrel saunas tend to heat efficiently and work well in smaller gardens, while cabin or pod designs often feel roomier and allow for more flexible layouts.

If you share your available space, how many people will use the sauna, and whether you prefer electric or wood-burning heat, we can guide you towards the best match.

Yes, many of our outdoor saunas can be tailored to suit your space and how you plan to use it. Options may include different sizes, wood types, heater choices, seating layouts, door styles, and extras such as porches or changing areas. Because we don’t display every available configuration online, some options are made to order.

If you have a specific idea or layout in mind, get in touch and we’ll talk through what’s possible.

You can choose between electric and wood-burning heaters:

• Electric heaters are easy to operate, heat up quickly, and often include timers and digital controls.
• Wood-burning heaters offer a traditional sauna experience, perfect for rural or off-grid setups.

We’ll help you decide which option best suits your space and lifestyle.

As a rough guide, many outdoor saunas reach temperature in 30–60 minutes, depending on heater type, outside temperature, sauna size, insulation, and how often the door is opened. Wood-burning can feel “faster” once it’s going strong, but it depends on fuel quality and airflow.

It depends on heater size and session length. A common setup might be around 6–9kW while heating up, then it cycles to maintain temperature.

The easiest way to estimate cost is: Heater kW × hours used × your unit rate.
If you tell us the model you’re considering and your typical session length, we can help you estimate realistically.

Your sauna needs a firm, level base so it sits square and drains properly. Most people use a concrete pad, paving slabs on a compacted sub-base, or a properly built deck/base frame designed to take the weight.

The key is level, stable, and good drainage — shortcuts here cause most long-term issues.

Often, an outdoor sauna can be installed without planning permission, but it depends on your property, location, and the sauna’s size/position (especially near boundaries).

If you’re unsure, it’s worth checking with your local council or your installer. We can also advise on typical placement considerations to reduce planning headaches.

Yes, outdoor saunas are designed for year-round use.

In colder weather it may take a bit longer to heat up, and wind exposure can make a difference, but the sauna experience is brilliant in winter.

Smart placement (shelter from wind) and a good base/drainage setup are the biggest “NI-proofing” factors.

Western Red Cedar is naturally resistant to moisture, decay, and insects without requiring chemical or heat treatment. Its porous cell structure means it stays cooler to the touch, even in high heat, making it more comfortable for sauna use.

Cedar also offers excellent dimensional stability, a calming natural aroma, and rich, warm aesthetics. These qualities make it a popular choice for those wanting a long-lasting, premium sauna experience.

How does it compare to Thermowood?
Thermowood (a heat-treated softwood) is a more budget-friendly option and still performs well in sauna settings. However, it can become hotter to the touch, may be more prone to cracking over time, and doesn’t have the same scent or visual appeal as cedar.

While both woods are suitable, Western Red Cedar is generally preferred for its natural comfort, beauty, and durability.

Lead times can vary based on the specific model and custom options. Typically, saunas are shipped within 12 weeks after the order is placed.

If you’re working to a particular deadline, get in touch before ordering and we’ll help you choose an option that fits your timeframe.

Most of our outdoor saunas are delivered as pre-fabricated kits, designed for straightforward DIY assembly. Each kit / crate includes the required components along with clear instructions. Depending on the model and access, some saunas may arrive in larger sections rather than individual panels – we’ll always confirm what to expect before delivery.

Our saunas are designed for DIY assembly and come with detailed, step-by-step instructions. If you’re comfortable using basic tools, most customers find the build process straightforward.

We also offer assembly videos and extra guidance to help along the way.

If left untreated, Western Red Cedar will naturally weather to a grey-silver tone over time. This is completely normal and does not affect the performance or lifespan of the sauna.

If you prefer to maintain the original colour, the exterior can be treated with a suitable product such as Osmo wood oil every couple of years to help slow discolouration and weathering. Treating the outside is optional — many owners simply allow the timber to age naturally.

Inside the sauna, do not use oils, varnishes, or harsh cleaning chemicals. Heat and chemicals don’t mix well and can affect both the timber and the sauna experience. A simple wipe-down with a clean damp cloth and good ventilation after use is usually all that’s needed.

Outdoor saunas, especially those made from solid wood like cedar, can occasionally let in small amounts of water, particularly in heavy rain or as the wood naturally expands and contracts. This is normal and not harmful. The sauna will dry out quickly when heated, and any minor water marks can be gently sanded away.

To minimise this, we recommend the optional roof (included with our package deals), which offers added protection and helps preserve the saunas beautiful finish over time. Regularly checking and tightening the aluminium bands (barrel sauna) will also help maintain a snug, water-resistant fit.

Yes, all Dundalk LeisureCraft saunas come with a manufacturer’s warranty that covers structural components. We’ll provide full warranty details with your purchase.

No problem, if you tell us your space, preferred heater type, and how many users you’re planning for, we can guide you to the right model and the right setup.
