I got mine from Signature Hardware. Lots of styles and finishes to pick from. The ones I got are a bit flimsy, which is ok unless they get foot traffic.

If you want a wood one to blend in with the floor, try Cape Cod Air Grilles. They have multiple sizes and wood species that can be stained to match your existing floor.

Get a custom wouod grille that SITS FLUSH in the opening.

A wood one is what you need IMO these are not decor items that you want to bring attention to.

A wood one won’t work with lvp fooor because of the thickness.

We were able to find this company tho and will be using them.

It’s a flush mount using your own lvp plank so it matches perfectly.

a little bit of practical advice: the openings on the wood vents are really small, which means more resistance, which means your furnace has to work harder. it's like the equivalent to shutting half the vent off. if that room is on the cold side, you might not be happy with that. I can't say that for sure, but just looking at them makes it seem pretty obvious.

also: somebody is going to have to cut into your floor to make the opening edges perfect. custom vent size + custom insall = expensive.

I'm not against these vents. they're very pretty! just some practical things to consider.

This is the company.

$120 for a template and one vent. I keep the template after. I also mail them some
Planks so they can match it.
