Glass Walled Pools
At Hydrosight, we make a clear distinction between underwater windows and glass walls. A glass wall is a special type of underwater window that replaces part of the pool’s side, giving a seamless, transparent view with no support beam above. The top edge is polished, and the plexiglass is securely mounted from the sides and bottom — perfect for above-ground pools.
The result? The pool water seems to end vertically, letting you see deep into the water without surface distortions.
Plus, it makes for stunning photos — capture a swimmer partly underwater, partly above, for that perfect Instagram shot.

Glass walls are often used in above-ground pools, but they’re equally striking in cantilever pools. Black Forest, 2021
Overflow / Infinity Glass Edge
A glass wall for a pool with an overflow is a transparent side panel that forms part of the pool wall, designed so that water flows over its top edge into a hidden overflow gutter or drainage system. This setup makes the edge of the glass invisible, creating a seamless look where the water appears to extend to the horizon — similar to an infinity pool effect.
In short: it combines a clear view into the pool with a continuous water surface that spills over the glass edge, giving a sleek, modern, and visually striking appearance.

Planing and Preparation
For each window request, Hydrosight provides detailed technical drawings required for the pool’s concrete work, including the precise dimensions for the window opening. This enables you to plan the installation and construction process accurately.
Meanwhile, the windows are manufactured and will be ready for shipment precisely when they are needed on site.
