Doheny's

Doheny's has carved out a loyal following over four decades, and its standout feature is the custom pool liner configurator, which lets shoppers design liners matched precisely to unusual pool shapes and sizes rather than settling for generic dimensions. That kind of specialization is hard to find elsewhere and speaks to real category expertise. Phone-based customer support is a welcome touch for a category where product fit genuinely matters and mistakes are costly to reverse. The $99 free-shipping threshold and 30-day return window are standard for the space, and payment options are broad. The main drawback is delivery speed: 5-10 business days lags noticeably behind competitors like PoolSupplyWorld or Pool Supplies Superstore, which could matter to pool owners racing to open for the season. Still, for liner replacements and kit purchases specifically, Doheny's specialized configurator makes it worth the wait.
