GFCI Requirements for Pools & Spas
Direct answer: Pool, spa, and hot tub equipment generally requires GFCI protection on essentially all associated receptacles and much of the fixed equipment, using devices rated to the stricter personnel-protection standard (Class A, tripping at roughly 4-6 mA) given the elevated shock risk of water combined with electricity.
Water's mineral content, not the water itself, is usually what actually conducts dangerous current near pool and spa equipment.
Why pools and spas get extra scrutiny
Standing in or near water dramatically increases the danger of even a small current leak, which is why code treats these areas more strictly than a typical dry indoor outlet — both in terms of which receptacles need protection and how sensitive the device must be.

What homeowners with a pool or spa should check
Confirm that pool/spa equipment receptacles and any associated GFCI devices are functioning and tested regularly — this is an area where an annual professional inspection is worth the cost given the elevated stakes.
