See Your Pond Differently

A raised pond fitted with a pond glass window brings life, clarity, and elegance to your garden — transforming your outdoor space into a vibrant focal point. Whether you're building a decorative water feature or a full koi pond, a high-quality koi pond glass window offers a crystal-clear view into the underwater world.

Unlike the distortion of viewing through water alone, pond glass windows provide uninterrupted visibility, allowing you to fully enjoy the colours, movement, and serenity within. Toughened and laminated for durability, our koi pond glass windows are easy to maintain and built to withstand the elements.

More than just a practical addition, a pond glass window is a bold design feature — adding depth, character, and a tranquil touch to any landscape.

How do Koi behave in winter, and how can glass improve visibility?

As an ectothermic species, the body temperature of koi fish is controlled by the temperature of the water. As the water cools, the koi fish become less active. They’re likely to gather in groups to provide warmth and will consume less food as their metabolism slows. Some may enter ‘tarpor’ which is a hibernation-like deep sleep.

Often pond owners consider adding a heater to their pond to avoid their fish getting too cold, and it’s imperative to ensure your pond is at least 3 feet deep to prevent it freezing completely and killing the koi. Due to the above factors, having a glass window means you can keep a watchful eye on the habitat and check for any signs of concern when the koi become less active and affected by the cold.
