I have a functional greenhouse sink! With running water and a drain and it’s beautiful! Below I answer some of the FAQs and go over some of the steps I took to transform the free stainless steel sink into the pearly white sink of my dreams!

How to Paint a Stainless Steel Sink:
Materials (click for links):
1.) Begin by cleaning the steel sink- I used Bar Keeper’s Friend and 0000 steel wool. Rinse and let dry.
2.) Scuff the sink with 180 grit sandpaper
3.) Lightly coat with primer. Once dry, sand with 220 grit sandpaper then apply another light coat of primer. (This gives a smooth finish). Repeat until the sink is covered evenly.
4.) Lightly coat with appliance epoxy paint, sanding with 320 grit between coats. Apply as many coats until evenly coated.
Most common question: How does it hold up? So far, it has held up great. This is epoxy paint similar to what would be on a refrigerator, so it is pretty durable. I did have to touch up some spots after we dropped it and it scraped on the asphalt…so it will scratch if you drop it.
Q: How did you run the plumbing?
We connected our faucet to a garden hose! This works in an extremely similar way to your indoor plumbing-the faucet stays on and the water flow is turned on/off from the sink handles! (We only hooked up to one handle because there is only one water temperature). Designs By Studio C has a great blog post showing step by step on how to hook the sink to a hose.
Materials I used:
Teflon Tape (seals the threads)
1/2″ female to 3/4″ female connector (this connects the hose to the faucet connector line)
Faucet connector line (1/2″ to 1/2″)
Q: Where does it drain?
We ran the drain right out the back of the greenhouse, and down an exterior pipe that waters my trees! (There will rarely be anything that is used in this sink that is not garden/plant safe).
Q: What materials did you use to make the drain?
I wanted so badly to use brass drain pipes, but life got in the way and I used PVC then spray painted the pipes gold to coordinate with the sink faucet! (sand pipes with medium-fine grit, clean with rubbing alcohol or acetone, then apply spray paint in light coats).

I absolutely love my greenhouse sink. This space gives the option to rinse off after an afternoon in the dirt and gives easy access to a water source for all those newly potted plant babes. And to think that my sink was FREE! it was already on the property when we bought it, and I’m so glad I was able to give it new life.
