An infinity pool comprises two troughs, namely, the initial pool and the collector pool. A waterfall drops from the main pool into the collector, creating the infinity effect. That's where the name comes from. The central section is made such that the walls slant from the pool, and the water is at the same level as the walls. These features make the pool a sight to behold. So, if you're considering putting up a pool on your property, consider an infinity pool.
