Description

The all-new ThermaSol PROIII-1200 generator is engineered for home steam rooms with dimensions 751 to 1200 adjusted cubic feet (ACF). The PROIII-1200 24kW steam bath generator accepts voltage in the range of 208V-240V, single-phase (1-PH) configuration.


The ThermaSol PROIII-1200 generator includes durable stainless-steel construction, professional-grade heating elements, advanced PowerFlush self-cleaning system, Smart Steam temperature control, Fast Start technology, stainless-steel drain pan, and a variety of other features.


PRO Series generators are engineered to provide the most consistent, pleasurable bathing experiences. The innovative Smart Steam feature helps ensure that steam is delivered at a constant rate without lags, bursts, and temperature fluctuations. The included FastStart technology provides quicker heat-up times.


The steam unit's split tank design helps ensure the longevity of the unit by separating the heating function from the water feed function. The generator includes the PowerFlush pressurized inner tank cleaning system which helps prevents harmful sediment build-up.


ThermaSol PRO Series generators are equipped with advanced CAN Bus technology for reliable two-way communication between the generator and the control.


ThermaSol PRO Series generators are compatible with the Thermatouch, Signatouch, Microtouch, Signature Control, Easy Start, Wellness Package, and Digital Shower Package. Select the available control or control package with features that best suits your bathing preferences.


The PROIII-1200 is designed so that steam shower accessories such as the Serenity, Light, Sound, Rainhead can easily be installed.


The PROIII-1200 steam shower unit can be installed up to fifty feet away from your steam shower enclosure. Common installation locations include closets, vanity cabinets, climate-controlled attics, and basements.


The PROIII-1200 residential steam generator carries ThermaSol's limited lifetime warranty and is fully serviceable. ThermaSol steam generators are UL and CSA listed for your safety.


Note: Generators sizing are listed based on Thermasol's theory on "Simple Sizing" of Cubic Feet = Length X Width X Height. No adjustments for materials.

Required control package sold separately.

What Our Customers Say

Real experiences from real customers

★★★★★

"I'll be honest, I almost went with a cheaper option on Amazon. Glad I didn't. James answered every single question I had (and I had a lot) before I even placed my order. The sauna showed up in 6 days, not a scratch on it. You get what you pay for, and with Sauna Republic you're getting people who actually care."

Mike D. Austin, TX
✓ Verified Buyer
★★★★★

"Okay so yes, I paid more than I would have elsewhere. But here's the thing — Tony called me twice just to make sure I ordered the right heater for my space. Twice! What other company does that? And when delivery got delayed due to weather, they kept me in the loop the whole time. No ghosting, no runaround. Worth every penny."

Rachel S. Minneapolis, MN
✓ Verified Buyer
★★★★★

"Shoutout to Tony for staying on the phone with me for like 45 minutes helping me figure out electrical requirements. I'm not handy at all and he walked me through everything. The team even followed up a week after delivery to see how setup went. These guys are the real deal."

Chris M. Denver, CO
✓ Verified Buyer
★★★★★

"Did my research for weeks. Yes Sauna Republic isn't the cheapest, but the warranty and their 100% guarantee made me feel way more comfortable dropping this kind of money. James was super helpful answering my questions about the cold plunge. Shipped fast, arrived perfect. No regrets at all."

Derek P. Phoenix, AZ
✓ Verified Buyer
★★★★★

"I was THIS close to buying from some random site that was like $800 cheaper. Something felt off so I called Sauna Republic instead. So glad I did. They actually coordinate delivery times with you, send tracking updates, the whole nine yards. My buddy bought from another dealer and his has been sitting in a warehouse for 3 weeks. Mine took 5 days lol"

Jason T. Nashville, TN
✓ Verified Buyer
★★★★★

"Big thanks to Tony who literally texted me updates when my sauna was in transit. Texted! Like a normal person! The communication alone made me feel like I made the right choice. Premium experience from start to finish. Already told three friends to buy from them."

Amanda K. Seattle, WA
✓ Verified Buyer
★★★★★

"Look, a sauna is a big purchase. I wasn't about to cheap out and cross my fingers. Sauna Republic might cost a bit more but you're paying for actual support, not just a product. James helped me pick the right model for my garage setup and the team checked in after install. Can't put a price on that kind of service honestly."

Brian H. Portland, OR
✓ Verified Buyer
★★★★★

"Was nervous spending this much online but Sauna Republic made it easy. Quick responses, they answer the phone (actual humans!), and my barrel sauna arrived in perfect shape. The lifetime support thing is legit too — emailed them a question months later and got a response same day. Solid company."

Lisa M. Chicago, IL
✓ Verified Buyer
★★★★★

"I compared prices everywhere. Yes there are cheaper options. But after reading horror stories about damaged shipments and zero customer service, I went with Sauna Republic. Best decision. Tony made sure everything was right before shipping and they coordinated with the freight company so I didn't have to sit around all day waiting. These guys know what they're doing."
