Our family went camping this month at Inks Lake State Park, about two hours from home. At the time, Jax was bathing in our sink at home. He was too big for the baby bath, but too small for the big bath since he can't sit up yet. So the kitchen sink it was. Thankfully, even though we were camping, we had a kitchen sink.
When my family camps, we get asked pretty much every day where we got this kitchen sink and counter. My dad proudly responds that he made it. It is a plastic six foot table from Sam's Club, a stainless steel sink from Habitat for Humanity, and a faucet and plumbing. A hose extends from the drain to a spot about twelve or fifteen feet away from our "kitchen." We use eco-friendly, biodegradeable dish soap, so we don't worry about the leftover food and soap draining down the hose into the earth. We don't have hot water, just whatever comes out of the "tap" at the campsite.
My dad totally needs to manufacture and sell these. We could be millionaires.
