Best way to mount counter top to wall with half supported by base cabinet

Hi - I am installing a 24 inch base cabinet with drop-in sink into a 60 inch butcher block top. So the rightmost 24 inches will be installed over cabinet while the leftmost 36 inches will be overhang but flush into a corner. What is the best way to support the left side to the wall? Is there a corner bracket that would support this? Total weight of counter is about 65 lbs.

I'd put a 1x4 on both walls. You could also put an end panel (it's the same exact size as a cabinet that matches the cabinet finish) on the left wall with a 1x4 on the back wall.

And then you will likely want a 1x4 across the front to strengthen that 36" span. Again, matching the finish of the cabinets.

Thanks. I'd also like to build a couple drawers to hang under the countertop side (this is a sort of utility sink/workbench combo going into the basement). Is it possible to mount slides directly to the bottom of the counter and slide a drawer right in? Or do I need to build some kind of frame for the drawers that the slides would mount to and then mount the frame to the bottom of the counter?

All depends on one drawer or two and what kind of hardware you want to use. Most drawer glides will be side mounted. You'd probably want a box with a face frame.

Just install a small 12 or 18" drawer base against the wall and you have solved all the concerns with one simple solution.]

Good idea - Problem is I'm building this setup around water meter/plubming in basement. 24 inch cabinet is all I can put against the back wall but I can have overhang all the way to the side wall with drawers to maximize the space in between cabinet and wall.

Best thing to do then is to make a plywood box that will fit exactly into the space left of your cabinet. It will have a bottom, sides, and a back. The top does not have to be one solid piece, it could be two 1x4s laid flat... one in front, one in back. And if you want 2 drawers you would put a divider in the middle.

The front of that box will get a face frame made of nice material that matches your cabinet. 1x2 typically. The openings in that face frame and the type of hardware you choose to use for your glides will determine how big your drawer boxes will need to be.

That box would then get installed on the wall just like a cabinet, screwed to the studs in back and probably one stud on the left. And your counter will sit on top. You can put a couple screws up through the top of it into your butcher block.

Even without the drawers you will need a support at the "front" corner of the counter where it meets the wall (left side). Someone suggested a 1x4. One of these needs to come out from the room corner almost (leaving space for drawer trim) to the counter front edge and be firmly fastened to studs in the left wall.

For shallow drawers under the "overhanging" part of the counter, the significance of some kind of frame in front is that such a frame can and should help support the weight of the drawers. The fact it has two horizontal members at least comparable to 1x2s on edge, one just under the counter and another under the drawers, will provide this support.

I would say that a plywood box with multiple drawers needs to help support the counter and not vice versa. The drawers and contents would represent a lot of additional weight
