Three stars

If anyone is thinking about a steam unit, they would be really foolish to consider anything else.

The best units on the market, made by a company that goes out of the way to put their customers first - what's not to love?

Michael K. Leesburg

I've never deal with a company as customer-oriented as Thermasol. On a scale of 0-10, my experience has been 12.

Have specified this product on multiple occasions. Their customer service and technical support team is fantastic. I love this product and will continue to recommend it to my clients and friends.

We absolutely love our ThermaSol steam unit, and we use it several times a week. It has had only one problem in 8.5 years, and ThermaSol's customer service was WORLD CLASS.

I wasn't familiar with this brand until I started designing our master bathroom. I thought I would go all Kohler, but the retailer I worked with turned me on to ThermaSol when he learned I was interested in creating a steam shower. ThermaSol truly stands out for incredible build quality, well integrated design, and outstanding customer service. I'm so glad I made this investment.

Love my ThermaSol! Just put a second ThermaSol in my vacation home and I have a ThermaSol from 2003 in my main house that has had no issues and still runs great to this day. Do the power flush thing once or twice a month like instructions say, and your generator will last forever!
