Under-Flow Pools
The Bourne\William® Under-Flow model is dimensioned with millimeter precision according to your architectural specifications. The final height of the terrace overhang is thus entirely under your control, while we ensure that the hidden technological solution flawlessly supports your vision. Furthermore, we tailor the entire structural system exactly to the chosen material of your surrounding area, guaranteeing an absolutely seamless and visually perfect result.
Who is this pool the best choice for
It represents the ideal choice for those who refuse to let any visible grating or classic edging disrupt the clean design of their terrace. If you are looking for an uncompromising way to unite the architecture of your house with the water surface and create a space free of visible transitions, the Under-Flow model with its hidden drain is the only right choice for you.
Where this pool will look its best
It creates the most powerful visual impact in modern, minimalist architecture, where the paving itself takes centre stage. The Under-Flow system is tailor-made for large-format surfaces such as natural stone, luxury ceramics, or poured concrete. Thanks to the overhanging edge, these materials extend directly over the water surface. It is the perfect solution for projects where you need to maximise the terrace area and render the pool technology completely invisible.
Absolute freedom of elevation
We respect the uniqueness of every space. Therefore, we give you the opportunity to individually define the height difference between the pool edge and the adjoining terrace. You can determine the exact height of the water surface and the overhang itself precisely according to your vision.
Perfect blending with the surroundings
With us, the pool edge is not an isolated element, but a seamless continuation of the architecture. The system is structurally prepared for the connection of the most demanding surfaces—whether you prefer the luxurious Hi-Macs® solid surface, first-class Italian ceramics, or premium wood. The transition between the water and the terrace is always absolutely unified.
Invisible boundary
The drainage trough is ingeniously integrated directly beneath the terrace overhang. The water thus elegantly disappears from sight, leaving behind only an undisturbed mirrored surface and a flawless aesthetic impression.
