Why these made the list
We began with a pool of 23 ThermaSol listings and narrowed to 3 distinct products: two steam generators and one controller. Our shortlisting rules required that each product be from the ThermaSol brand and have clear product type information. We compared specifications such as generator capacity, power output, and included accessories. All selections are based on the seller's published specifications and the manufacturer's catalog. Prices are displayed live and may change.
Things to weigh before buying
Sizing a steam generator
The generator must be matched to the volume of your steam shower enclosure. ThermaSol and other manufacturers specify generators by cubic feet; for example, the SSA-84 is designed for up to 84 cubic feet. Measure the length, width, and height of the shower to determine the cubic footage. For higher ceilings or uninsulated walls, consider a more powerful unit to ensure quick heat-up and consistent steam.
Power and electrical requirements
Generator power is expressed in kilowatts (kW). The power output indicates the heating capacity of the unit. A higher kW output corresponds to a larger heating capability, which can be beneficial for larger steam enclosures. However, higher power requires a corresponding electrical circuit.
Controllers: touch, digital, or wireless
The controller is the interface you use to set temperature, timer, and often additional features like lighting or aromatherapy. ThermaSol offers a range of controllers. The MTC-SN Microtouch is a contemporary option with a satin nickel finish. When selecting a controller, confirm that it is compatible with your generator model, as not all controllers work with every generator.
Installation and maintenance considerations
Steam generators require a cold water supply, a drain line (if you want automatic flushing), and a dedicated electrical circuit. Locate the generator in a dry, ventilated area close to the shower to minimize steam line length. Regular maintenance, such as flushing the tank to remove sediment, extends the life of the unit. Some models offer auto-drain options, which automate this process.
Questions
How do I know which ThermaSol generator size I need?
Measure the interior dimensions of your steam shower (length, width, and height) and multiply to get cubic feet. Compare that number to the generator's specified capacity. For example, the ThermaSol SSA-84 is designed for 84 cubic feet. If your shower has high ceilings or non-insulated walls, a larger generator may be needed to achieve comfortable steam temperature.
Can I use any ThermaSol controller with any generator?
Not all controllers are universally compatible. The listing for each controller typically states which generator models it works with. In our pool, the PROIII-395 includes a matching SignaTouch control, while the standalone MTC-SN is marketed as a ThermaSol accessory. Always verify compatibility with the manufacturer's specifications before purchasing a separate controller.
What electrical requirements do ThermaSol generators have?
Steam generators require a dedicated electrical circuit. The specific voltage and amperage depend on the generator's power output. For example, a higher kW generator may require a 240V circuit, but always check the product's specifications and consult a licensed electrician to ensure compatibility with your home's electrical system.
Do I need a drain for my steam generator?
A drain is not mandatory, but it is recommended for automatic flushing and easier maintenance. Without a drain, you will need to manually flush the tank monthly to remove scale buildup, especially in hard-water areas. Some generators offer an auto-drain option that flushes after each use, reducing manual work and extending the unit's lifespan.
