With a regular pool, the water is contained by visible walls that are higher than the water level. An infinity pool has one or more walls that are right at the waterline so they're not truly visible. For an invisible look, the lower wall is often made of glass or clear acrylic. The water laps over the lower edge and into a catch basin below where it gets pumped back into the pool.

In-ground pools are more durable and have a longer lifespan, but aboveground pools are an excellent option for homeowners on a budget. Aboveground pools are also easier to remove if you no longer want to maintain one.

The cost of an aboveground pool is $800 to $5,000 for materials and $1,000 to $3,000 for labor. Before deciding, weigh the pros and cons of each pool.

Most of the time, though there may be some code variations on the local level, a water source like a pool requires a GFCI breaker. These breakers detect electrical leaks of 5 mA or more and trip the breaker. However, the size of the pool and motor type determine the exact GFCI needs. A GFCI outlet with a reset button may be enough for an aboveground pool with a small motor or pump. Consult a pool electrician to determine the appropriate installation and protection measures needed for your pool.

A well-built and well-maintained concrete pool should last anywhere from 50 to 75 years. Concrete is prone to cracking, so winterization and regular pool repairs are particularly important. Water can seep into existing cracks, freeze, and make them worse. Most homeowners should resurface their concrete every few years to maintain their pool’s lifespan.
