Underwater windows are waterproof and load bearing. They provide a clear view below the water's surface. There are many possible applications: Scientific observation, architectural design or just for leisure. Underwater windows are suitable for private and public pools, Jacuzzis, large aquaria, industrial settings, residential and public buildings, for flood protection or as a design feature.
Hydrosight is the expert in the field of underwater windows. Our employers have worked on hundreds of projects around the world and installed custom transparent pool walls and floors in hotels, spas and private residences, panoramic windows and aquarium panels in zoological and oceanographic institutions, in touristic semi-submarines, glass-bottom windows in cruise ships and underwater skylights for renowned companies.
Now and Then
Underwater viewing windows used to be an expensive and complicated component and could only be found in public aquaria and the most exclusive facilities. In recent years, however, they have become more common. Architects and homeowners now frequently choose underwater windows when they are applicable.
Hydrosight plays a vital role in the rapid development of underwater windows. Ever since the company was established in 2003, Hydrosight has always made easy installation and safety an absolute priority. Underwater windows should provide the same or better safety ratings than any other standardized building component.
Designed for Safety
Hydrosight Underwater Windows are designed and built in Germany. Each product is individually calculated and tested to withstand the water pressure required from the habitat of the window. They are shatter-proof, so the risk of damage while on transport or during installation is negligible. We are very proud of the fact that all operating Hydrosight windows, that we know of, are still in service today. Many of our innovations, not to forget the patent pending double-sealing technology, have made underwater windows not only safe, but also affordable.
Hydrosight Underwater Viewing Windows are built with the pool builder in mind. We are constantly reevaluating how we can make them easier to install. They do not only need to be rigid, but also fault tolerant. This is what makes underwater windows now so popular with pool builders.
Check out our available options and sizes and browse our website to get to know our range of products, and what would suit you best. We offer a wide variety of setups, ranging from big projects of several tons of weight, all the way down to small portholes for budget prices.
Each underwater window is individually made for you on time. You require a window where size and depth rating suit your exact requirements? Contact us if you have a question, need consultation or if you want to order.
Strong and Waterproof by Design
Underwater windows need to be strong enough, but also need to be waterproof. Hydrosight is unique in enabling you, the builder, to have these requirements covered. Hydrosight will enable you to install our underwater windows, just as any other building component. Therefore we work with glazing, that sits in a stainless steel frame. The cost of just the window is higher, but the total cost of material and installation is lower. Plus: You stay in control of your operation.
The underwater window installation procedure is easy and well tested. As a pool builder you will not require any special training to install our windows. A step-by-step manual is provided and you have email and telephone support.
Our windows do not demand top ideal conditions for operation. Tolerances in the concrete shell are acceptable and do not intervene with the functioning of the windows. Hydrosight glazing is shatter proof, so the risk of damage while on transport or installation is neglible.
additional warranty by the manufacturer.
Hydrosight windows are rated IPX8 (suitable for permanent underwater pressure). The equipment is suitable for continuous immersion in water. The depth is specified by Hydrosight for each individual window.
Pressure Tested Seal
Each Hydrosight Underwater Window is marked with a signed Pressure Tested seal. It shows that all seals of the window have been tested OK for the required water depth.

You have probably experienced large acrylic windows in public aquaria. These are the type of windows which Hydrosight refers to as underwater windows. Apart from aquaria there are many uses for these windows, as well as a variety of fields in the market where the windows present themselves as useful. Let's explore together.
Glass Wall Flood Barriers
Some buildings are situated near rivers, lakes or oceans where the water level can change unpredictably. These buildings have to withstand the worst case-scenario floods, even if that might only happen once in a hundred years. Windows below the waterline of a flood have to keep the water outside the building. Both wall and window have to be specifically engineered.
Public pools and hotels thrive to differentiate themselves from competitors and add additional experience for their visitors. Have a look at the ratings at Booking.com for the Helsinki pool Hydrosight helped to build. A good example for Hydrosight providing you with the gear for unforgettable memories.
Film / Photography
Film directors and cameramen have discovered the use of underwater windows for the shooting of underwater scenes. This offers them an escape from the burden of scuba-diving and the costs of the specialized equipment required. Any photographer who has actively shot scenes underwater will tell you of the difficulties involved.
Professionals have all the time and ability to capture the right light and timing when they do so behind a window.
Hydrosight underwater windows are very versatile. They have been used in water purification plants for examination of water quality.
- Observation vaults of rivers, streams, coastal areas.
- Storage tanks for ice.
- Industrial portholes.
Acrylic is the ideal material for aquarium construction. It has been used for many years in building fish tanks, but never for such wide commercial use. Hydrosight has, over the years, acquired good knowledge and experience in this sector.
Sports Facilities and Public Pools
Originally used as an aid to swimming and diving instruction, underwater windows enable the coaches to observe swimmers and divers in action. Coaches can stand on eye level with swimmers, remain dry, and even use cameras for televising all aquatic activities.
Diver tank viewing ports are possible even at great depth. Hydrosight technology has increased maximum depth from 11m (35') to 20m (60') in 2019.
Pool Bottom Windows
Transparent elements in the bottom of water bodys are mostly found in swimming pools. Glass elements in pools are popular as a natural source of light for the rooms below. The mechanical load on horizontal windows is higher than for (vertical) windows installed in the walls. The load grows with the water level of the pool. That makes these skylights a natural supplement to reflecting pools, which tend to be less deep.
Recently underwater windows have been discovered by modern architects as a new design feature. Used in pool walls they can illuminate adjacent rooms and give the swimming pool an individual touch of design.
A journey to the submarine world can create memories which are unique and unforgettable. If you're all about exploring the submarine world inside the protection of a hull, you will require a suitable window for the observation of the outside.
Hydrosight's ship windows can be installed either next to the water line, or they can be submerged. They can be used either for maritime observation, as well as for monitoring the floor of the sea.
Hydrosight offers both custom cast submarine windows, certified by a classification society of your choice, and plain windows cut to size, certified by authorities like Germanischer Lloyd.
Acrylic is the material of choice for viewing facilities in a pressurised vessel.
