Pools are never going to be as inexpensive as they are today. An average play pool in 2019 can be 45K and a fully optioned pool/spa can easily exceed 55K. We constantly strive to deliver the absolute most pool for your money.
No one likes to hear ".....it depends...." because it's so open ended. Once the permitting process is complete, with an accurate plan, good weather, and some good project management, an average backyard pool should take around 4-6 weeks to construct.
There are specific circumstances where each one is better suited. Here's a few of the most common conclusions. Salt will cost more long term but feel better on your swimmers today. Salt systems make chlorine*, not replace the need for chlorine. Salt generators are expensive to replace....and you will have to replace the cell.
*if the pool is running, the water chemistry is within limits, there are no leaves clogging the cell, and there is an adequate saline ppm in the pool water.
