re: Diy outdoor kitchen cost?

Check with your permit office, I had to tie into existing sewer. Pulling just cold water with under counter water heater. 14'x24' slab, covered with single gable roof, around 30 ft counter top J shape, doing concrete tops, building the frame out of metal framing studs, facing with stone, sink, ice maker, fridge, built in pit, and side burner, corner fireplace (same stone as bar.) Total should come out to just under 10K and Im doing most of the work myself, I had to use a plumber and electrician due to dumb arse city ordinance. Good luck OP, its a fun project so far. My main advice is plan, then have someone look over it for things you might not have accounted for.
