Overall we are pleased with this 3 man sauna. Service and delivery was very fast and efficient and items were in stock in the UK which was key for a quick delivery before lockdown. It fitted up the stairs easily enough for a 3 man sauna It came in 3 huge boxes 52kg to 72kg in each box so its a v heavy load so needs a few people to shove up the stairs. Areas for improvement - Make mains wire longer. It wont reach a typical UK plug even if its parked right next to the socket. It needs a lot longer wire. Its not ideal messing about with extensions on a heating device that takes a lot of power. - Sauna bench has screw holes at the back sunk in the wrong place so you have to remove left and right carbon panels to be able to install it as you cant get a screwdriver to the holes otherwise - The sauna bench itself is a little too narrow. There is plenty of space to extend it and because the panels extend onto the bench you do loose a lot of space so its not ideal for lying down - Speakers could do with Bluetooth as the aux wire doesn’t look so great hanging out the front – are there any BT attachments you can get - Some of the clips on the back panels were so stiff a screwdriver was needed which meant we had to pull the whole sauna out to get to them as we could not get enough access to use a screwdriver (but could with hands but too stiff to move) - Sizes were slightly bigger than advertised and we had a specific space to put it in. Unfortunately this meant we had to collapse 5 wardrobes and rebuild everything in a different place because the measurements were not 100% online as I don’t think they included the doors in the depth of the sauna at 155cm – it was more like 158 by the time it was built. We could not access our loft hatch so had to move the whole sauna. - It DEFINITELY DOES NOT TAKE ONLY 15 MINS TO BUILD as even having built and unbuilt it twice it took far longer than 15 mins. Its just an unrealistic timeframe but it was v easy to build ! Overall though the sauna is great and feels high quality and crucially is from a UK company that can offer direct service and support so i would recommend over buying from overseas.
