Vinyl Remnant or Peel & Stick Tiles (Redwood City)

I am in search of a vinyl remnant or 12” peel & stick tiles to fill a 6‘ x 3‘ floor. My hope is to find something in a natural, dark, neutral color, with either a “stone“ or “wood plank“ look. Photos are examples.

Unfortunately, the space is so small that purchasing flooring to fit it would be extremely expensive, since a large quantity would have to be purchased.

If you have a remnant piece or tiles laying around, I would sincerely appreciate them.

Thanks!
