I think the sink is going to have all of these things and more. From the trailer and from previous screen sots i saw work/reloading benches and at 0:21 on the trailer I saw manequins with armor/clothing on. I feel that this will truly be a Home Base for the player.
For a while the question I posed to my friends was "Why would you choose any other house besides Abandoned BOS Bunker?" Now the question will become "Why would you choose any other house besides the sink?"
So what do yo think? do you think it will have a rad free water source? a campfire/hot plate? a fish tank? Discuss.
