Glass bottoms (horizontal underwater windows) by Hydrosight create transparent pool floors that transmit natural daylight into spaces below and allow visual access into the water from beneath.
Overview- Product family: horizontal underwater windows (glass bottoms / pool skylights) intended for installation in the pool floor or as elevated reflecting-pool surfaces.
- Forms: single glazing panels or modular arrays combined to form larger transparent floors.
- Pool types: compatible with tiled pools, liner pools and other pool constructions.
Sealing and structural integrity- Integrated assembly built around a stainless-steel frame to support load and embed sealings.
- Double-redundancy sealing system delivered as a sealed unit to minimise leakage risk through the pool base.
- Material choice and assembly designed for impact resistance and reliable performance, including in seismic areas.
Maintenance- Compatible with standard chlorination regimes to control biofilm.
- Use of automated pool-cleaning devices is recommended to remove settled particles while avoiding abrasion of the glazing and preserving light transmission.
Orientation- Vertical alignment: window installed in or functioning as a pool wall (vertical underwater window).
- Horizontal alignment: window installed in the bottom of the pool (glass bottom / pool skylight).
Applications & references- Typical applications: rooftop swimming pools, reflecting pools and elevated water features where daylighting and visual connection beneath are required.
- Documented installations in UK, Israel, Finland, Austria, California, Florida and other locations; project references available from Hydrosight.
