Swimming pools beneath floors have been around for about 75 years. In fact, the pool in Beverly Hills High School Swim Gym is hidden under its gym floor, and it was built in 1939. This marvelous architecture has served as a location for movies like the 1946 film 'It's a Wonderful Life' and James Franco's Whatever It Takes. And it could be installed in your home if you have the resources.
According to Digital Trends, companies like Guncast, Hydrofloors, and Agor Creative Engineering, specialize in 'hydro floor' construction and design. These companies say opting for this kind of pool has a number of advantages. Apart from the space saving features, constructing your pool this way consumes less energy because the floor prevents heat loss. They also say it is safer as height could be adjusted depending on the client. It could serve as a diving pool, a kiddie pool, or a mid-level pool for water workouts or games.
Agor Creative Engineering promises its clients that their movable floors covering their pools have passed strict safety standards. Their website says, "The rigid floor completely covers the swimming pool and the water is inaccessible, guaranteeing maximum safety with a secure, highly-durable surface, giving you peace of mind."
You would be surprised that a lot of residential and commercial spaces choose to have this constructed. Another hydro floor provider called Guncast states, "They are particularly sought after in cities, like London, where space is at a real premium, but we have also fitted them in country mansions. People like the fact they can benefit from having a swimming pool in a space that can double up for other uses as well. It also provides ultimate safety."
The floor finish is often the same material and color as the rest of its surrounding floor, so people may not know that there is water beneath the surface where they are standing. It takes about 10 minutes to open up the movable floors to reveal the magical pool underneath it.
