And no filler shown here:

Filler shown here.

Is there a “right” way to do it?

Depends the door..........Sometimes it is needed for a door to fully open . As with a full overlay door

agree with ProSource Memphis. Filler scribed to the wall. Think about it; if your wall isn't level and you pop in a cabinet there could be some pretty good sized gaps. With a filler that is scribed it will follow the wall and then there will be no gaps. Plus, door opening all the way.

Plus, I'd use the designer that said it was needed. If a designer said it wasn't needed chances are they aren't the sharpest knife in the drawer

What kind of cabinets are you looking at? My uppers have a single face frame, which had extra wood on both ends, allowing them to be scribed. It allows the doors to be opened a bit wider. You should also check if adjacent window frames protrude.

So each of these was a different cabinet company.

Cabinets.com designer put the filler piece into the design.

The Starmark designer said you didn’t need it. They are full overlay. He said that the door wouldn’t open all the way because it would hit the window molding, but that I could get a stopper so the hinge wouldn’t allow it to extend all the way.

It’s confusing me though because the starmark guy has been SO thorough about everything. He’s been very conservative and “safe” about everything else. I had one area that only had 2.5 inches of filler instead of 3 and he pushed for changes just in case my walls weren’t flush so the handles wouldn’t bump. He also said I should go with a 37” fridge cabinet for my 35.75 fridge because the fridge needs airflow on the sides. No one has ever said anything about that to me before.

So anyway...he’s been really conservative and thorough about everything so I don’t know what to think about this.

I’m not sure if starmark is scribed on the sides. Maybe that’s why? Going to look into it.

A scribe is done at INSTALL. ALL the cabinet company provides is the material. "Scribe" is a method. not a material

Hi @101newkitchen101 not sure if you've come to any decisions but we recently worked w cabinets.com, are mid-install now and can share this - we had a couple iterations of our design...in 1 design there was a filler where cab hit wall, in other there was no filler so we deiced to do what made sense to us.

For us, our wall was straight/plumb enough where we had option to go without filler.

We saw pros/cons as follows:

Pro, with filler you can open cabinet all the way without the knob hitting wall - I assume this is why others said it is typically added to non-custom cabinets. **Also our cabinets are partial overlay so we can open door with cabinet flush to wall....so to other poster's point, with a full overlay cabinet I don't think your door would open

Cons with filler - our run of cabinets would be a few inches longer...more importantly we would have line where filler meets cabinet edge that we'd need to fill.....

We ultimately decided to go without the filler to save the extra few inches and prevent having that line where filler meets cabinets.

Hope this helps and good luck!
