Powering the everyday

FirmaFlow® Therm & Ceratherm T

The Ceratherm T collections by Ideal Standard deliver top performance every day, because they were developed from the inside out. Thanks to the hidden brilliance of FirmaFlow® Therm, one can enjoy an unrivalled levels of durability, safety and performance - with an ergonomic design that delivers the pure showering pleasure, day after day.

Hidden brilliance since 1969

The original. Perfected.

We wanted the Ceratherm T range to perform brilliantly, yet be as slim as possible. That is why we developed FirmaFlow ® Therm: a revolutionary smaller thermostatic cartridge. 

It provides safety and efficiency, while enabling us to create a streamlined design, ideal for any project, for both high- and low- traffic environments.

FirmaFlow ® Therm is designed to power every product in the range over a long, problem-free service life.






Efficiently enjoyable

Less water, less energy.
More calm for you.

Our integrated controls reduce waste in a number of ways when compared to traditional mixers.
FirmaFlow ® Therm is so efficient that it reaches the target temperature much faster and thus saves energy. With the Eco setting, you can limit the flow rate up to 50% without affecting performance. In addition, our Idealrain hand showers have a flow limiter that ensures maximum water efficiency. 


Water is important - that's why we don't waste a drop. The water temperature in our thermostatic fittings is preset and remains constant during use. And the thermostatic mechanism automatically controls the hot and cold water flows and helps you save water.
These innovations not only reduce water consumption, but also improve the use of every single drop. At a time when water is becoming increasingly valuable, they are part of our efforts to protect this important resource in everyday life.

Temperature regulation - exactly correct, every time.

A perfect bath or shower has to be the perfect temperature. FirmaFlow® Therm allows installers to preset a desired temperature level. You can also choose to set a maximum limit, which can be altered with the push of a button. Should the hot or cold water supply unexpectedly cut off, FirmaFlow® Therm will automatically stop the shower to protect from shocks and scalds – restarting under your control when the water supply returns.
