Hey everyone! I'm in the middle of reinstalling my kitchen after discovering some water damage. I thought I was careful in matching the cabinet and sink sizes, but I ended up with a sink that's 33" wide and a cabinet that's only 30". The cabinets are already installed and level, and the new countertop is on, but I haven't cut the sink hole yet. Should I try to make this work, or is it better to swap out the sink cabinet for a larger one? Any advice would be greatly appreciated!

Before you make any bigger changes, check the inside of the cabinet to see if the sink basin will fit without hitting the sides. If you plan to go for a bigger cabinet, you'll need to carefully unscrew it from the wall and deal with your adjacent cabinets. A lot of folks in your situation typically just opt for a 30" sink and leave everything else the same, which saves a headache!
You might want to consider replacing the sink cabinet with one that’s designed for a 33" sink. This could mean replacing the two adjacent cabinets as well, depending on your setup. If you're set on keeping what you have, I'd suggest switching to a single bowl sink that's meant for a 30" cabinet. Ruvati is a brand I like for that sort of thing!
What about the Glacier brand? I saw it at Home Depot and was curious!
Honestly, cutting down the sides of your cabinet could be a solution if you prefer not to replace it. You might end up with what's known as a 'bump out,' extending the sink cabinet slightly. It might not look perfect, but it can work if you're okay with it. Just remember, if you're working with a drop-in stainless steel sink, it’s usually more forgiving for fitting than an undermount. You have a custom countertop, so keep that in mind while planning your next steps!
Thanks for the insight! My sink is a drop-in stainless, and I've already custom-built a black walnut countertop. I'm leaning towards replacing the cabinet to avoid any potential issues.

I'm worried about whether I could secure the sink properly after making changes. What do you think?
