The ThermaSol PROIII-1200 is a 24kW steam shower generator designed for home steam rooms between 751 and 1200 adjusted cubic feet (ACF). As part of the PRO Series III, this model features Smart Steam Technology (patented), ensuring consistent steam delivery without temperature fluctuations for a seamless and luxurious bathing experience.

Equipped with FastStart Technology, this generator produces steam in seconds, while PowerFlush Technology provides a pressurized self-cleaning system to remove sediment buildup and extend lifespan. Its split tank design further enhances durability by separating the heating and water feed functions.

For added protection, the stainless steel drain pan and pre-plumbed safety relief valve simplify installation and maintenance. The CAN-Bus digital communication system ensures seamless operation with ThermaSol’s digital controls and accessories.

The PROIII-1200 can be installed up to 50 feet away from your steam shower, making it ideal for placement in closets, vanities, climate-controlled attics, or basements. It is UL and CSA listed for safety and backed by ThermaSol’s limited lifetime warranty.

  • Smart, steady steam control – Patented Smart Steam Technology delivers consistent temperature and vapor flow, eliminating fluctuations or bursts so every session feels smooth, balanced, and comfortable from start to finish.
  • FastStart convenience – Exclusive FastStart Technology produces steam in seconds, not minutes, allowing you to enjoy a relaxing steam experience almost instantly without waiting for preheat or idle time.
  • PowerFlush self-cleaning – Pressurized inner-tank flushing removes sediment and scale buildup automatically, extending heating element life, improving efficiency, and minimizing manual maintenance between uses.
  • Split-tank longevity design – Separates heating and water-feed chambers to reduce thermal stress and contamination, improving long-term durability and ensuring reliable performance even in high-demand settings.
  • Advanced CAN-Bus communication – Provides secure, two-way digital communication between the generator and compatible controls for responsive operation and seamless integration with premium accessories like HydroVive and Serenity systems.
  • Installation-ready safety – Includes a stainless steel drain pan, pre-plumbed safety relief valve, and braided stainless steel water connector for secure connections, faster setup, and added system protection.
  • Durable stainless steel build – Constructed from corrosion-resistant stainless steel and certified to UL and CSA standards, ensuring dependable, long-lasting operation under continuous use and humid conditions.
  • Warranty coverage – Protected by a limited lifetime warranty, offering peace of mind and long-term assurance that your investment is supported by ThermaSol’s quality commitment.
