The diving pool in the swimming pool may be colder than the other pools because it is typically shallower and more exposed to the air, which can cause the water to lose heat more quickly. Additionally, the diving pool may not have the same heating system as the other pools, leading to a temperature difference. The other pools may be warmer because they are deeper and have better insulation, as well as a more efficient heating system to maintain a comfortable temperature for swimmers. **

It is possible that some people may urinate in public outdoor pools, but it is generally considered inappropriate and unsanitary. Public pools typically have rules and regulations in place to discourage this behavior, and lifeguards and staff are trained to monitor and maintain the cleanliness of the pool water. However, it is important for swimmers to be mindful of their own hygiene and to use the restroom facilities as needed to help keep the pool water clean for everyone. **

Chlorine smells stronger in indoor pools than in outdoor pools because of the enclosed environment. In indoor pools, the chlorine fumes are trapped within the enclosed space, allowing them to build up and create a stronger smell. In contrast, outdoor pools have more ventilation, allowing the chlorine fumes to disperse more easily, resulting in a less intense smell. Additionally, indoor pools may have higher levels of chlorine to compensate for the lack of natural sunlight, which can help to break down chlorine compounds. **

Diving goggles are not allowed in the swimming pool because they are designed for use in deep water and can obstruct peripheral vision, increasing the risk of collisions with other swimmers. Additionally, diving goggles are not necessary for swimming laps or recreational swimming in a pool with clear water. The use of diving goggles in a swimming pool can also create a safety hazard if the wearer dives into shallow water thinking it is deeper than it actually is. **

Round pools have the advantage of being easier to install and maintain due to their simple shape. They also tend to have a more natural and aesthetically pleasing look.

Additionally, square pools can be more cost-effective to build, as they utilize space more efficiently. Ultimately, the choice between round and square pools depends on individual preferences and the specific needs of the pool owner. **
