Absolutely love it!!
I have used my fair share of saunas and this is by far one of the simplest ones yet. Effortless and such a great design! Wish I had invested sooner… thanks for the customer service team for being so easy to deal with. I can’t wait to purchase my ice bath next!

Great product but some nuances
I love my sauna and use it 4 or more times per week. Still using it and it hasn’t lost its appeal even after 12 months. The sauna is still performing perfectly.
One downside is that I bought the 4 person sauna and it isn’t long enough to lie flat on the bench and if I had to purchase again I would get the 8 person size.
Also read the fine print. You do need 25 Amp power to the heater which needs to be installed by an electrician and buried 60cm which for me was more costly than expected as it required cutting through a section of concrete driveway.
I still love my sauna and would definitely buy it or a bigger one again if I ever move house.

The People Behind The Product
I couldn’t be happier with my Revel Sauna! The quality is excellent - easy to assemble and it delivers an amazing sauna experience. What truly sets Revel Saunas apart though, is their customer support. From pre-purchase questions to warranty claims, their support team (Vanessa) was responsive, knowledgeable, and genuinely helpful every step of the way. I highly recommend both the product and the people behind it!

Beautiful product
Apart from the aesthetics, the Duo Ice Bath is the perfect addition to my Sauna routine and allows me to use the Sauna in the summer months when I'm heating the pool. Very happy with the Revel Ice Bath and would highly recommend!

Best purchase ever! Morning cold plunges are the best!
I absolutely love the Revel Glacier Duo Ice Bath! It has become a staple in my daily recovery routine, and the quality is unmatched. I typically use it in combination with my Revel Aura Infrared Sauna, doing 3-minute cold plunges at 4°C between 20-minute sauna sessions. This contrast therapy has worked wonders for my recovery and overall well-being.
The design of the Glacier Duo is sleek, and the temperature control is incredibly precise, which makes it easy to get that perfect chill every time. It’s also spacious enough for a comfortable plunge but compact enough to fit seamlessly in my space.
For anyone serious about recovery or simply wanting to add cold exposure to their health routine, the Glacier Duo is hands down one of the best investments you can make. Highly recommended!

The Revel Aura has been a total game changer for my recovery routine, especially after a long day at work. I also got the glacier duo cold plunge for contrast therapy...it’s a quick, effective way to reset. I usually do 20 minutes in the sauna followed by 3 minutes in the ice bath, repeating the cycle a couple of times and makes my recovery and sleep so good!
It heats up fast, and the full-spectrum infrared feels amazing. It's helped reduce my muscle soreness and stress after hard workout days. If you're looking for a convenient way to improve recovery at home, this setup is so good!

Excellent product and value for money
I have had a few infer red sauna’s and the expensive ones, to have a product like this for the price you pay is excellent.
I have always wanted a traditional rock sauna and and am very pleased with it.
I have the 1 person which is perfect for 1 person, you can sit up long ways on the bench with your legs bent, but you can, which is great,. When you pour water on the rocks, sometimes it is quite hot, so you wouldn’t want to have someone standing up at all like the previous post.
I’ve had in the past a three person sauna, and we found that we hardly ever put more than one person in the sauna, so this time having a single is perfect, but it has lots of space for that single person.

We love our Tampere 4 Person Traditional Sauna. The delivery process was first rate. The unit was easy to unpack and assemble. The customer support was first rate as we learnt how to use the sauna correctly.
We use the sauna in the middle of the day to take advantage of solar power. The sauna sits nicely in the indoor pool area so that we have easy access to the shower, spa, pool and sauna.
The daily sauna experience is something we look forward to - pure relaxation. We feel more energetic and healthier since we've started using it.
We highly recommend Revel Saunas - great products, great service, great prices. I guess it's ice bath next.................

If you ever decide to upgrade to the 8-person model down the track, we’d be more than happy to help. Thanks again for your support and kind words!
