They sell sinks at TSC, but I've never bought one since the hose needs to be turned off it as I've got it splits or leaks.That is so nice, thanks! I've told my husband we're putting in some raised beds in front of our regular garden area. I want to grow a lot more veggies since the canning bug has bitten me! We just put in an old porcelain sink & drinking fountain out by the garden. Now all we need is a porcelain toilet! (The neighbors would love that!)
Now I expect your husband can fix your sink to take a hose attachment. Good too should you process your birds you could wash them right there.
I've always considered buying one of those two burner propane set ups for boiling water to process birds too.
