A lot depends on the wood's age, area harvested, etc. Can you add a picture comparing it to your sample boards? From what I can see, it looks much as I would expect...

Might have expected a tad darker… but what you have is a very nice timeless mid tone brown. I’d be happy.

I think they look about right. Ironically, less than a week ago I had the EXACT same issue with exact same stain color and sealant, except my floors are red oak, so they turned out a bit more yellowy/pink. I arrived home and was shocked - had expected (and wanted) at least 2 shades darker. I strongly considered an immediate redo but after a few days i think they are growing on me...

They look about right on white oak. The wood can only absorb what it can.

Love your floors!

I live your floors too! Beautiful stain job!

They look great. It’s furniture and rugs, you’ll love them more.

If you are stlil reading - is it Miniwax provincial? I love how your floors turned out, I am looking for sth like that for if the ktchen cabinets.
