Most pools can safely remain empty for 1-2 weeks, but inground concrete pools face structural risks after this period due to hydrostatic pressure. Above ground pools can stay empty longer but may suffer liner damage.
Inground pool costs range from $35,000-$100,000+ depending on size, materials, and features. Concrete pools are most expensive ($50,000-$100,000), vinyl liner pools are mid-range ($35,000-$65,000), and fiberglass pools fall in between ($40,000-$85,000).
Not all pools need liners - it depends on your pool type. Above-ground pools require vinyl liners for waterproofing, while concrete pools use plaster finishes instead of traditional liners.
Inground pools last 10-100 years depending on the type: concrete pools can last 50-100 years with proper maintenance, vinyl pools typically last 10-20 years, and fiberglass pools last 25-35 years. Proper maintenance is the key factor in maximizing lifespan.
Concrete pools do not need liners like vinyl pools, but they require a waterproof finish such as plaster, aggregate, or tile to prevent water loss and provide a smooth swimming surface.
