Heres one

White oak quartersawn slab cabinet door from Barker's. I didn't look through their gallery for a finished kitchen but they might show one.

Just remember they are made from plywood and the plywood can be very repetitive in pattern. Also each piece will vary greatly from flecks and grain and pattern.

Best case scenario is you choose the veneer and they make the panels for you. Most people choose the actual sheets of plywood as you would be surprised how you have an idea what looks good and what the builder does. Not all quarter sawn white oak panel look the same especially panel to panel so seeing a picture does not mean your will look anything like that in the end. Ask to see the sheets first.

We are having ours custom made and will be solid wood. Just trying to decide between rift or quartersawn. Love rftsawn, but its $1200 more. Quarter sawn seems lovely, and would like to save the $- but kept finding it in shaker style.

KT O, our bases are QS Oak, Shaker (almost 14 years old). I think thd rift is a more uniform look. Almost all of ours have the shimmery rays and flecks, which is a feature, not a bug. I actually think the kitchen Patricia posted is rift sawn.

I wouldn't choose QS over Rift as a money saver. They're different enough that I think you should decide which grain you love, and if you can't picture the QSO, do the rift.

(Have you searched through Kitchens under rift and QS. You might find photos. I don't know why I thought I saw slab QSO cabinets posted in someone's thread.)

Found this 2015 Houzz thread discussing the choice you're facing.

I think these are quartersawn slab cabinets. It's the reveal photos from remodelfla's kitchen mentioned first in the thread I just posted above:

No substitute for current samples. There's a lot at stake.
