    There are two things in life that I absolutely need. Breath and my Trinity Sauna.

    Are used to just do hot yoga for getting my sweat on, but now that I purchased the Trinity Cydne, this takes my health and wellness journey into a whole another level. Recommend 100%.

    Just using this sauna one time, I feel better than I have in years. I love the combination of infrared heat and traditional steam. Not ask for purchase a better product.

    Thank you Finnmark Designs for a great product. I had a 3 to 4 person that I gave to my mom. Now after buying this Trinity there is no comparison.

    The Trinity Santa is the focal point of the room. It is something I love to show off to anyone.

    Ive only tried traditional saunas before I purchase this one. Adding the infrared is defiantly a different experience. I dont feel as claustrophobic, and I feel like my core really heats up faster than just a traditional. I am very fond of this product.
