Thermostatic control and 4 functions in a clean, premium shower column
Thermostatic wall-mounted shower column with 4 water functions, a 20×26cm rainfall shower head, piano-style buttons, and adjustable height of 75–145cm.
The Wallex HydroFlow is a 4-function thermostatic shower column with a 20×26cm rainfall shower head, shower handset, hand spray, and fixed water outlet.
The thermostatic mixer with a 40°C safety stop helps maintain a more consistent temperature, while the independent piano-style buttons let you quickly select the function you want.
HydroFlow requires no concealed installation and is a simpler, more affordable alternative to HydroTech when you do not need a digital LED display and the available installation height is suitable.
Everything you need in a well-designed shower system
HydroFlow retains the key benefits of a premium thermostatic system without adding unnecessary complexity. You get a thermostat, four functions, and straightforward controls in one wall-mounted unit.
More consistent temperature for your everyday shower
The thermostatic mechanism helps limit sudden temperature changes during use.
More options than a basic shower column
The rainfall shower head, shower handset, hand spray, and fixed outlet offer different ways to use the system.
Choose your preferred function instantly
The independent buttons make operation clear and quick, without complicated rotary selectors.
Wide rainfall coverage
The rectangular shower head offers a wider coverage area and an adjustable angle.
75–145cm to suit your installation
The column can be adjusted to position the upper shower head at the right height, provided the water connections are in the right place.
A more practical bathroom upgrade
The main unit remains wall-mounted and does not require the system to be installed inside the wall.
The column height does not start at the floor. It starts at your water connections.
This is the most important point to know before choosing HydroFlow. The final height of the shower head depends on the location of the hot and cold water connections.
In modern installations, the water connections are usually around 90–100cm above the finished floor. If yours are around 1 metre high, the adjustable 75–145cm column provides a typical overall shower head height.
In older bathtub installations, the water connections may be considerably lower. In that case, HydroFlow may end up lower than you would like—not because the column is unsuitable, but because the installation starts lower down.

First, measure the height of your water connections
Measure from the finished floor or tiles to the centre of the hot and cold water connections. This is the point from which the shower column installation effectively begins.
Connections at around 100cm
This is the most typical setup for HydroFlow. With the adjustable 75–145cm body, you can set an appropriate overall height for everyday showering.
Connections below 90–100cm
Carefully check the final height before buying. This is more common in older installations originally designed for a bathtub.
Need more height?
Consider the Wallex HydroTech, which has an adjustable range up to 145cm and adds a digital LED temperature display.
HydroFlow or HydroTech?
When you want a thermostat and 4 functions without an LED display
Adjustable height of 75–145cm, 20×26cm shower head, piano-style buttons, and 40°C thermostatic control. Ideal when your existing water connections are at a suitable height.
When you need more height and an LED display
HydroTech reaches up to 145cm and adds a digital temperature display, making it a better choice when your existing connections are lower or you want more room for adjustment.
Care for consistent flow and a clean appearance
Anti-Clog nozzles
Make it easier to periodically remove limescale from the water outlets.
Gentle cleaning
Use a soft cloth and a suitable non-corrosive cleaner.
Regular checks
Periodic care helps keep the functions and water outlets in good condition.
Frequently asked questions
Is HydroFlow short?
The column has an adjustable height of 75–145cm. However, the final height of the shower head also depends on how high the hot and cold water connections are. If the connections are very low, the overall installation will end up correspondingly lower.
How high should the water connections be?
For a well-planned installation, the water connections are usually around 90–100cm above the finished floor. Before buying, measure your own bathroom and calculate the final height of the shower head.
I have an old bathtub and the water connections are low. What should I do?
In older bathtub installations, the water connections may be lower than the modern standard height. In this case, check the final height before buying. If you need a wider adjustment range, HydroTech reaches up to 145cm.
What is the main difference between HydroFlow and HydroTech?
HydroFlow is the simpler version without a digital LED display and adjusts up to 145cm. HydroTech has an LED temperature display and a greater height adjustment range of up to 145cm.
What does thermostatic mean?
The thermostatic mechanism helps maintain a more consistent selected temperature and limit sudden changes during your shower.
What functions does it have?
It has four water options: rainfall shower head, shower handset, hand spray, and fixed outlet.
How large is the rainfall shower head?
The shower head measures 20 × 26cm and has an adjustable angle.
Does it require concealed installation?
No. It is a wall-mounted column, and the system’s main body does not require concealed installation.
Do I need a plumber to install it?
For correct fitting, connection to the water supply, and adjustment of the thermostatic system, installation or a final check by a qualified professional is recommended.
