Long time no post and ok maybe not a DIY l, but my husband decided to bring a shower to the beach to rinse the kids off (all the sand on the ground is what came off of them). The water was warmish because it was in the car while we played and having the hose was nice. Everyone that walked by the car asked about it and what do you know, you can buy it on Amazon. Just put it in a tub of water and go. LTKFamily LTKTravel LTKSeasonal
