I know of no way to change the venting on the hood. What size is the hood?

Do you have the capability to have the pipe on the hood turned to go out the back and you just think it'll look weird? (Sort of sounds like it might be the case from how you phrased it.) 'Cause if you have that kind of metal working skills available, you could have the actual duct elbow out the back part way up (cover it with drywall or wood or something stylish to look like an extra beam for support) and have the chimney continue up to the ceiling for looks.

I'd get a new hood.

The hood is pretty big at 55". I'm just so tired to the extra costs and time as things go wrong. Mind you, we had taken out drywall and checked first but apparently not far enough.

I'm dealing with venting right now too. It occurs to me that there's what you see, and the actual mechanicals. The chimney can be altered so that the vent curves out to the back wall and the chimney continues straight up for looks. It's all in how you connect the sheet metal that makes up the actual vent. The big question is, do you want to do the work? It's much easier to deal with an appliance made for your space. Wouldn't it be so much easier to use an insert, connect it however you like, then put a front on it?

@eam44 that's my plan B. I'll have to build the hood and hope it looks decent. Just no funds left to play around. I have to throw money to remodeling my parents' room now.

Oh beach....hang in there. I've run out of money several times... I'm beginning year two of my reno, and I'm still surprised every time there's a glitch! You'll figure it out. Good luck!

Can you turn on messaging on houzz? I may be able to help.

I do have messaging on.

Just sent you a message.
