Bestway Power Steel and Intex Ultra XTR are excellent choices for long-lasting pool kits. With the right maintenance, such as winterizing and balanced water chemistry, Intex's steel frames and triple-layer PVC liners last five to ten years. When stored properly during the off-season, Bestway's Power Steel series' sturdy liners and rust-resistant frames will last for more than seven years.
Wilbar's Citadel or Sahara kits are extremely durable, with a lifespan of 10 to 15 years, but they might require expert installation. For weak materials, stay away from Atlantic and Sharkline. Make use of a quality cover and filter, and routinely inspect the liners.
