I built a outdoor sink/produce wash station. I used treated lumber to build the frame and hardware cloth to make a drying rack. We bought a stainless steel sink with faucet and sprayer off Marketplace for $10. I hooked that up to a garden hose.
Materials used;
2 4x4x8 treated lumber for the legs
12 2x4x8 treated lumber for frame
10 1x6x8 treated deck boards for the shelf and counter
#10x3" outdoor treated screws
#7x1 1/4" stainless steel screws
For the plumbing
2 12" long braided stainless steel flexible faucet supply line with 1/2" FIP connectors at both ends
2 3/4" x 1/2" diameter threaded male hose x MIP adapter fitting
1 12" 3/4" hose thread outlet rubber washing machine connector
#10 x 3" exterior grade wood screw
#7 x 2 1/4" stainless steel screws
