A simple solar shower beats the fancy ones.

Yes, the cheap black bag with a hose works better than you’d think. No batteries, no pumps, no weird dripping after three uses. Hang it on your car antenna or a tree, wait ten minutes for the sun to warm it up, and you’re good.

The fancy pressurized ones (like the Nemo Helio or something similar) are nice, but they cost triple and weigh more. For most beach trips, you just need to get the salt off before the drive home. A two-to-three-gallon bag will give you about two minutes of rinsing—enough for one person to get clean, or two people to do a quick pass.

The only thing that matters is a decent shut-off nozzle. If the bag comes without one, buy a separate trigger nozzle for five bucks. Otherwise you waste half the water trying to rinse with a steady trickle.

Don’t overthink it. Spend the extra money on a good beach blanket.
