Go to a plumbing supplier and look at sinks and see what you like? Often sink dimensions measure the overall width including the flange- in your case you can get a sink whose bowl is up to 33” wide as long as they scoop out the sides of the cabinet.

A 33" sink undermounts into a 33" sink base cabinet without scooping the cabinet sides. You'll have to strap, not block or clip, your sink in place.

Get the largest sink that fits in your cabinet please. Virtually everyone who replaces a sink installs a single bowl.

Joseph Corlett, LLC - I saw that you had something similar on a different post and another said you were the guru🙂

How does the strap system work? Do the counter installers do this? where do these come from? Any tutorials to recommend? We are on a budget and trying to avoid extra expenses.

My cabinet is 34.5” ( cabinet maker used 1.5” fo for garbage pullout). At the designing stage I figured I could have a 32 or 33” sink. Now I am finding that sink specs make it necessary to go down to a 30” sink.

I have to get this figured out to order a sink. Cabinet maker says they’ll be ready mid - August.

Extremely grateful!

Just be prepared for a fabricator that refuses to listen to a customer's request. I even provided my own straps (recommended by Joe) for the fabricator to use on all my sinks, but he pretended to use some, skipped the rest and just used the clips that he always uses.

Going to counter place Tuesday and will see what they say - if they install sink or we do and if they do - will they do straps. otherwise my spouse will. Thankfully he is a fairly handy and capable guy - and does high quality work. He has done all the reno so far on this project except drywall and electric. We hired HVAc for a new HE system so we could take out chimney and bulkheads and We are also hiring cabinet maker and counters.

Thanks for your advice!
