kitchen cabinet height question

[Parrothead]

Can I trim the corner of the last cabinet? Or notch the sheetrock on that weird angled wall?

Thanks

Don't trim the back corner of a cabinet! That's what holds it together.
Are there any spacers you can trim? Yeah, notching the wall may be an option, but can turn into a headache, since you still need to have sheetrock there.

You can absolutely trim the corner of the cabinet BUT you must reinforce the corner FIRST and I’d do it by running a piece of 1x4 vertically at a 45 degree angle inside the corner. Of course you’re going to have to miter the edges of the 1/4 to fit in in snug, but it will then be the new part of the cabinet supporting the weight and holding it together. Hopefully I’ve described this okay. I’ve actually seen this done and it held up to the best of my knowledge.

It's one thing when the cabinet is sitting on the floor, and another when it is hanging on a wall, and yet another when it is supporting a wall oven, and other stuff stacked on it.

Using a 1x4 mounted like a vertically oriented piece of crown molding may keep the box together, but it really compromises the strength of the assembly. If you did this between two adjacent cabinets, or against a side wall, where some support can be given to the face frame, then that might not matter, but in this situation, the right side of the face is exposed.

Then, there is the consideration of your reinforcement impeding the drawer operation in the bottom.

A stronger option would be to fill in the inside of the corner with a solid triangle of wood glued (and screwed) in. You just must cut it at 45 degrees on two sides to get the grain oriented across the corner. Then, you could trim the corner a little. Perhaps as much as 3/4" without compromising it.

Your example is exactly what I was trying to describe, but obviously I described it poorly! I’d use a 1x4, but a solid piece of wood is likely better.
