Love love love this sink!!!  Was nervous about the size but if you Have the room get the 33!  It does not disappoint!  Grate is fantastic!  We got our kitchen up and running just in time for thanksgiving this year and doing dishes in this sink is a joy.  Trim is needed for sides. I read all the reviews. Our cabinet maker added some but we are going to change.  You will most likely need trim. 
Fabulous farmhouse sink.  Very elegant.  It’s a happy sink!
