ThermaSol Exclusive Features
Combining revolutionary smart home technology with six decades of engineering expertise, ThermaSol has created the most advanced steam generator available on the market today. Delivering the highest quality steam shower experience, ThermaSol’s PRO Series generators provide constant steam, temperature control and care-free maintenance, all backed by a Lifetime Warranty.
Smart Steam Technology
Available on ProSeries™️ III models only. SmartSteam produces the precise volume of steam required to maintain your desired room temperature while providing a quiet, relaxed experience.
State-of-the-art floor-to-ceiling temperature uniformity within the steam shower. No more variable heat ranges. Also allows the closest proximity to the outlet to give you more usable shower space.
Split Tank Technology
Provides steam at a constant rate while ensuring trouble-free reliability! Water is pre-heated in the steam generator’s water reservoir and passes to the boiling side on demand.
Finally, an effective way to automatically purge calcification build-up from the inner tank of the steam generator. ThermaSol’s exclusive Powerflush technology uses concentrated household water pressure with integrated speed slots to sweep the bottom of the internal tank, removing build-up effectively and efficiently.

If anyone is thinking about a steam unit, they would be really foolish to consider anything else.
Los Angeles, CA
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.
Fair Oaks, CA
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.
Santa Barbara, CA
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!
