Hawaii beach restrooms and showers matter when the beach is only one part of the day. A toddler needs a bathroom. Grandparents need a short walk from the car. Everyone needs a way to get sand off before lunch. The beach that wins on scenery can lose the moment those constraints arrive.
I use a facility-first test: decide how long the stop must work, identify the one amenity your group cannot do without, and reject any beach that fails it. Use this guide for facilities planning, our Hawaii Beach Finder to narrow your options, and the Ocean Report for the current water check.
