Height is not everything – the turning radius also matters
Choosing the right shower tray siphon is a key stage in bathroom design, especially when aiming for modern, barrier-free solutions that are easy to maintain. Most attention is usually given to the height of the siphon, which is indeed crucial—the lower it is, the easier it fits within floor layers, simplifying installation in thin floors or during renovations of older buildings.
ut this is not the only parameter worth considering. Another, often overlooked yet equally important aspect is the turning radius of the siphon, i.e. the distance from the vertical axis of the drain to the end of the horizontal outlet.
What is the turning radius and why is it important?
The turning radius determines how much horizontal space is needed to connect the siphon to the drainage system. The smaller the radius, the greater the installation flexibility—especially in tight spaces or where access to the main sewer line is limited.

In standard siphons, this distance often exceeds 150–180 mm, which can significantly complicate installation or require costly floor modifications or rerouting of other installations. In contrast, solutions with a small turning radius allow the siphon to be connected conveniently in almost any situation, without the need to interfere with the floor structure.
Speed and Speed 2 siphons – compactness in its best form
That is why we developed the Speed and Speed 2 vortex siphon line, combining low installation height with a minimal turning radius. Their design has been optimized to simplify installation as much as possible, without compromising drainage performance or build quality.
✔️ Installation height: adapted for low-profile and barrier-free shower trays
✔️ Turning radius: only 110 mm – nearly half of what traditional siphons offer
✔️ Compact design: ideal for fast and reliable installation even in the most demanding conditions
✔️ Vortex technology: ensures efficient water drainage and reduces the risk of clogging
