Pond Portal Advantage

Standard size includes 48" Wide by 24" Tall window frames designed to rest into a standard 8" block wall with or without a 1" veneer. Alternate block wall thicknesses may be used to allow thicker veneers (Brick, Natural Stone, etc...) or the window may be offset to accommodate no veneer and bring the window flush with the exterior side of the wall.

Other standard sizes are in development and coming soon!

We are happy to receive custom orders. Custom orders are quoted on a case-by-case basis.

All Pond Portals Frames are crafted from 316 Stainless Steel. 316 Stainless Steel offers the best possible resistance to environmental degradation and ensures a lifelong premium finish.

Pond Portals provides a flush-mount design. This allows the pond to be part of the wall rather than sunken behind the wall. 

Pond Portals are ready to securely seal any pond-rated flexible liner. Fiberglass and other pond liners may also be suitable with minor modifications to the installation process.

Glass is unquestionably the best solution for a pond window. Glass does not scratch easily or break down in direct sunlight. Tempered laminate glass offers layers of safety to ensure your pond safe.

Pond Portals are engineered with the DIY in mind. We like to equate the DIY difficulty level to a bond drain or filter installation. In this case, a little bit of research in block laying is all you need to follow our installation process. If you have any doubt please contact us and we can help answer your DIY questions!

We provide detailed step-by-step instructions that provide a "how to install pond window" guide within our Pond Portal Manuals.

The Pond Portal includes an innovate multi-purpose feature that ensures a strong connection to the wall and a water-tight seal with the liner. This strong wall connection is achieved through an anchor on the retaining flange that sets into the mortar layer between each block. This same anchor functions as a threaded system that locks in a retaining flange which is used to compress and retain the flexible liner in place. 

Traditionally, open-top window frames are tricky to install because the two vertical sides may slightly bend out of alignment. Pond Portals eliminate this problem by utilizing the retaining flange as part of the installation process to ensure the frame is installed square with the wall and the glass.
