An Olympic Swimming Pool
The world standard for competitive aquatic events/Everyday Places
An Olympic swimming pool is precisely 50 meters long, 25 meters wide, and at least 2 meters deep, holding 2,500 cubic meters of water. That water weighs 2.5 million kilograms, which is why you never hear about someone building one on the second floor. The pool must be kept between 25 and 28 degrees Celsius, and each lane is exactly 2.5 meters wide.
