The Evening Bay Pool Liner from Blue Wave offers a contemporary take on a classic liner pattern — deep blues highlighted by a crisp light blue create a shimmering, water-like effect that gives above-ground pools a timeless, sophisticated appearance. Blue Wave’s proprietary welding process creates smooth, durable seam connections that resist separation and leaks season after season — an advantage over heat-sealed alternatives. Standard-gauge vinyl provides reliable strength for residential pools, resisting punctures from everyday swimming while built-in inhibitors help reduce fading and sun damage, keeping the deep blue pattern vibrant year after year. Installation is straightforward with the overlap design — fold the liner over the steel pool wall and secure with standard coping strips (sold separately). The overlap fit offers flexibility that suits both first-time installers and experienced pool owners, with no precise track alignment required, whether tackling a first-time install or a routine seasonal liner replacement for above ground pools. No professional installation required. Sized for 27-ft round above-ground steel wall pools with 48 to 54-in wall depths. Not compatible with inflatable or soft-sided pools. Pairs well with pool pad underlayment, automatic pool cleaners, and pool vacuums for a complete above-ground pool setup. Also available in additional round and oval sizes to suit a range of above-ground pool configurations. Backed by Blue Wave’s 15-year limited warranty, U.S. customer support and over 35 years of pool industry experience, this pool liner replacement delivers dependable performance and lasting value for pool owners.
