Customer Reviews
The steam room that I purchased was the four person room outside. It started off with a little flowers, but working with the company they corrected the mistake and they were understanding they were patient and they were persistent. I really appreciate the product is the best product of I’ve had When you install this it must take 2 to 3 people or get a professional install. I approve of the product. I’m really enjoying it. My family is really enjoying the product and it has did a great lift for my health and my body considering I am a first responder and my coworkers all the thrill with the product themselves when they come over to visit thank you again for all the understanding and making sure that this product was the best experience for me. Thanks again guys
I love how it feels inside when it’s hot and looks beautiful in my backyard. Highly recommend it.
They really make great products. It looks very slick, works great. Hired the assembly service and 2 guys put it together in less than a day. It gets very hot, fits 4 people comfortably, maybe 5 small, easy to clean. Would recommend.
Carole and I wanted to thank you and the team for our beautiful outdoor steam room you customized to fit our needs. You hit the mark.

- Breathing Comfort: Steam rooms like the Grand Geyser luxury steam room are ideal for those who prefer moist air, which can help ease respiratory discomfort, unlike the dry air of saunas, which may feel harsh.
- Spa-Like Feel: The Grand Geyser provides a luxurious, relaxing atmosphere, ideal for an at-home steam room experience, while traditional saunas offer a more rugged, intense heat.
