Underwater windows are waterproof and load bearing – Where Transparency Meets Strength

Underwater windows – Where Transparency Meets Strength

At KÔBO Architectural, we transform water into a design experience. Using PMMA (acrylic glass) and advanced engineering, our aquatic windows deliver absolute watertightness and exceptional durability—built to inspire and designed to last.

Crystal-Clear Views Beneath the Surface

Our transparent walls and portholes provide unmatched clarity, almost invisible to the eye. That’s why they are chosen worldwide for private and public pools, luxury spas, hotels, restaurants, aquariums, scientific centers, as well as industrial and urban projects such as flood-control systems, windbreaks, and sound barriers.

Spectacular by Design

Placed at the bottom of pools, aquatic windows become dramatic underwater observatories. Suspended pools open breathtaking views over city skylines or natural landscapes—like the iconic 25-meter glass sky pool at Embassy Gardens in London.

From Small Portholes to Monumental Walls

Every project is custom-made: from compact round portholes to seamless 20–25 meter monobloc panels with no visible joints. Whether residential, hospitality, industrial, or avant-garde architecture, our solutions bring bold visions to life.

Global Expertise, Prestigious Projects

With decades of expertise in aquatic glazing, we have delivered iconic projects worldwide: transparent pool walls and floors, curved panels, skylights, and underwater windows for luxury hotels, spas, private residences, aquariums, cruise ships, tourist submarines, and research institutions.

Innovation Beyond Windows

• Motorized sliding aquatic doors: stainless steel framed, façade-integrated, perfectly sealing indoor/outdoor dual-use pools.

• Submersible guillotine windows: large-scale glazing lowering vertically into the pool, with surfaces up to 3 m wide and 4.6 m high—with no vertical mullions.

From monumental structures to refined details, every KÔBO creation is engineered to measure, built to the highest standards, and delivered on time. Our team supports you with personalized advice and world-class technical expertise.
