Key Benefits:

✔ More Heat, Less Waste – Retains 75% of firewood’s heat for better sauna performance.

Hot & High Quality

Ordered this sauna fall 2024 and we love it. Took about 2 weekends to get it put together myself but it went pretty well. We chose pine over cedar to save some money and still don't mind that we did so. I'm biased but always recommend getting a wood burning stove whenever possible. We regularly reach 200+ degrees in ours. No better feeling during a Minnesota winter. I installed a metal roof this fall for the looks and to potentially avoid wood rotting on the roof. The original roof should be fine with the ice & water shield it comes with but I wanted to upgrade it anyway. Lastly, I have to mention the customer service for this purchase has been like no other. Any questions or requests I had were addressed immediately by Topture. I got more than I expected from them and have already recommended them to several people looking for saunas. SO if you're thinking about it, JUST DO IT already..

We should have bought it years ago

We thought about buying a sauna for years and finally did. We absolutely love it, especially in the winter. It’s incredibly easy to assemble with two people the whole family uses it.

True North 5 Person Sauna

I purchased this Sauna in White Cedar with 2 Windows and the Harvia Electric Heater and absolutely love it! It was easy to assemble in a few hours and is very high quality. I got the manual dial and it heats up quickly and provides up to 80% humidity when putting water on the rocks. The instructions were excellent and no extra help was required. It was shipped to me in the US and although it took awhile to receive because of a manufacturing issue, Topture kept on top of the situation and kept me in the loop from start to finish. They are an xlnt company to purchase from. Sandy Potter

Handles snow and cold like a champ

I initially had concerns about the snow load with the True North 5 Person Outdoor Cabin Sauna, but it’s handled heavy snow with no problem at all. Paired with the HUUM Drop 7.5kW heater, it delivers an amazing, steamy sauna experience that I highly recommend. Big thanks to Topture for all the support, answering my questions, and just always being there throughout the whole process!

Ultimate Wellness Experience

As someone who has tried multiple saunas over the years, the Finnmark FD-4 Trinity Infrared & Steam Sauna Combo is by far the best I’ve encountered. It heats up quickly, and the infrared heat feels soothing, while the steam option delivers that classic, deeply relaxing sweat.
Installation was straightforward, and it fits perfectly in my home. My partner and I use it several times a week, and it has truly elevated our wellness routine. Whether you’re looking for relaxation, detoxification, or just a moment of calm in your day, this sauna offers it all. Highly recommend it!

An Investment in Wellness, Exceptional Quality and Craftsmanship

I was initially hesitant about the Dundalk Leisurecraft Georgian Cabin Sauna Canadian Timber 6 Person (CTC88W) because of the size and the price point. However, after using it for a while, I can confidently say it's worth every penny. The quality of the Canadian timber is top-notch, and the craftsmanship is evident in every detail. The space easily accommodates six people, making it perfect for family gatherings or a relaxing session with friends. The heat distribution is excellent, and the cabin design gives it a rustic, cozy feel. I also appreciate the durability of the materials, which seem built to last through years of enjoyment. If you're serious about wellness and long-term value, this sauna is an excellent investment.
