Can I cut bottom of my cabinets off to add height to my countertops?

Are you referring to your UPPER cabinets?

I don't believe you can alter already-made cabinets like that. It might be possible to re-mount them higher on the wall, though.

I'm a little confused. If you want to add height to the countertop, why would you cut off the bottoms? Sorry - just want to understand your question. You can trim the bottom of your cabinets but you would have to be extremely careful to trim them evenly so they are level, and not trim so much that the doors won't open easily. If you're trying to add height to your counters, then you could add a base for the cabinets to sit on.

I think you are talking about cutting off your upper cabinets to make more space in the area between your counter top and upper cabinets. My question is whether or not your upper cabinets go all the way to the ceiling. If not--you can raise those upper cabinets all the way to the ceiling. If you are short--it would be harder to reach things on the upper shelves but you would gain more space. I would not cut the cabinets. Maybe you could remove the upper cabinets and install open shelves at the height you want for more room.

No, cutting the bottom of any cabinet will cause a problem with the structural integrity.

Your cabinets should have been screwed into the walls and the cabinets on each side. You should be able to unscrew them and move them higher. Then your backsplash will need to have something added on top to cover the open wall area and that should give you more height above your countertop.

Its an Old house and the cabinets are from ceiling to about the height of a Yeti cup from my countertop! Which means I cant put hardly anything on my counters...coffee pot, Dish drainer, canister sets, etc 😟

I had thought about trimming off part of the bottom shelf and making the new 'bottom shelf' like 2-3 extra inches in height...hope that made sense! Or...Can I not take the bottom shelf off, trim the outer walls, and replace the bottom. Could use it for lids or saucers! This would be easier if I could send you a pic of the cabinets that I am referring to. Lol
