An inground pool costs $80 to $250 per square foot with installation or $25,000 to $100,000 total, depending on the size and material. Fiberglass and vinyl swimming pools cost less than concrete inground pools but don't last as long. Small plunge pools and semi-inground pools cost less than average.
Over the course of swimming pool history, pool finishes have advanced in incredible ways. When pools started popping up in backyards in the 1950s, the main option for pool owners was white plaster finish. Then pebble finishes were introduced in the 1980s and color options exploded into what we have today: interior surfaces in almost every hue, texture and style imaginable.
