What are the exact dimensions?

It is 36 inches wide, 24 inches high and 12 inches deep. That 36-inch width is sized to bridge a standard range or a gap between upper cabinets.

Is it really solid wood?

Yes. Ridgeline states solid wood construction with no particleboard. Expect to sand and finish raw wood surfaces yourself.

How many shelves and doors does it have?

Two doors and one shelf, noted as 2D-1S. The single shelf splits the 24-inch height into two storage zones.

Can I paint or stain it?

Yes, that is the point of an unfinished cabinet. Sand, prime and paint, or stain and seal, to match your kitchen. Do this before hanging it if you can.

Does it come with hinges or handles?

The listing does not specify hinges or hardware. Confirm with the seller before ordering, since door mounting hardware is usually sold separately on unfinished cabinets.

Will it match standard wall cabinets?

Its 12-inch depth and 24-inch height are common wall cabinet dimensions, so it lines up with typical uppers. Check your cabinet line's door style and overlay before pairing it.
