I assume you the drain size request you mean the actual PVC pipes.
The shower drain should be 2" and the kitchen sink should be 1 1/2", the vanity sink can be either 1 1/4" or 1 1/2. ( 1 1/2" is the better option).
Little about a lot and a lot about a little.

2" is the correct size for the shower drain however the sink drain line would depend upon which code you are under.
Under the IRC (International Residential Code) a kitchen sink requires an 1-1/2" drain line.
Under the UPC (Uniform Plumbing Code) a kitchen sink waste arm (the section extending out of the wall) should be 1-1/2" but all concealed piping in the wall must be 2".Comment
