The average lifespan of an inground pool can vary depending on the type and quality of construction, materials used, the climate where it is located, and how well it is maintained. A concrete or gunite pool typically has a longer lifespan than other materials, such as vinyl liner pools. \
A properly built and maintained concrete/gunite pool should last 25 years or more, while a vinyl liner may need to be replaced every 8-12 years due to wear and tear from exposure to UV rays. \
Furthermore, proper maintenance, including regular cleaning, testing of water chemistry levels, skimming for debris, and vacuuming, will increase the life span of any inground swimming pool. \
