Glass Bottoms for Swimming Pools

Those pictures on Instagram or Pinterest seem surreal! Pools up in the sky like being weightless. Large glass bottoms open the view into the water from underneath. Swimmers being observed like moving through the air - hence the term Sky Pool.

Glass bottom pools are real, actually. And there is a company that makes them: Hydrosight is the market and technology leader when it comes to installing transparent bottoms for basins. It is essential to be able to build on a partner like Hydrosight for such an operation. Still, it remains teamwork between architect, general contractor and pool builder. Together with Hydrosight this unique attraction will become a success.

Glass bottoms for pools are actually just a variety of Hydrosight's underwater window product range. Internally Hydrosight refers to them as horizontal windows, in opposition to vertical windows, that go into the pool wall. Horizontal windows can be installed in any kind of pool, no matter if tiled, liner or other. Single glasses are common, but also arrays of openings to form even larger windows.

Reflecting Pool Glass Bottom

Integrating horizontal glass panels into elevated water features, such as rooftop pools, provides a unique aesthetic, channeling natural daylight into the architectural spaces below. This feature is effective for both swimming pools and shallow reflecting pools.

Sealing and Structural Integrity

The Hydrosight system provides a robust, integrated assembly. The system utilizes a stainless steel frame and is equipped with a double-redundancy sealing system. This structure ensures the window is a completely sealed unit, making leakage through the pool base highly improbable—offering protection equivalent to the primary roof waterproofing. The material's inherent strength provides excellent durability and impact resistance, ensuring reliability even in seismic zones.

Maintenance

The system is designed for straightforward maintenance. Standard chlorination helps inhibit biofilm growth. For removing settled particulate matter, an automated pool cleaning device is recommended. This method maintains a spotless surface while preventing abrasion of the acrylic, preserving optimal light transmission.
