Now offered in three distinct models, the Pro Series combines the latest technology with ThermaSol durability, performance and efficiency to ensure a consistent steam shower experience every time. Each Pro Series model is crafted with the same industrial-grade stainless steel and lifetime warranty, plus performance-engineered to deliver constant steam at a constant rate, split-tank technology and state-of-the-art energy efficiency technology. Pro Series II and III offer the next level of sophistication with an advanced cleaning system. Pro Series III is the only model to feature the ultimate in smart steam temperature control.

  • Warranty coverage – A comprehensive lifetime parts warranty with two years of in-home service and lifetime factory support lowers ownership risk, controls long-term costs, and ensures fast assistance if components or performance ever need attention.
  • Constant, comfortable steam – Advanced control delivers steam at a steady, consistent rate without surges or drop-offs, maintaining even temperature and humidity so each session feels smooth, predictable, and relaxing from warm-up through cooldown.
  • Industrial stainless build – Stainless steel tank and components resist corrosion, pitting, and thermal cycling, preserving integrity and output for dependable daily use with fewer service interruptions and a longer service life.
  • Split-tank efficiency – Separated heating and water-feed sections improve energy transfer and reduce scale stress on elements, enhancing performance, shortening recovery, and extending component lifespan for cleaner operation and lower maintenance over time.
  • Flexible remote installation – Place the generator up to 50 feet from the shower without upsizing kW, opening placement options in closets or utility nooks for quieter baths, easier service access, and cleaner aesthetics.
  • Safety-ready plumbing – A pre-plumbed safety relief valve and 1/2" union streamline steam-line connection, support code compliance, and provide reliable over-pressure protection, helping installers commission faster while homeowners enjoy confident day-to-day operation.
  • Secure smart connectivity – A water-tight data link cable maintains stable communication between the generator and control unit, preventing moisture-related dropouts so commands, diagnostics, and updates transmit reliably in high-humidity environments.
