Plumbing diagram for bathroom with tub and shower cobo, vanity and toilet

Try again with a LOT more detail. It's easy to post a picture using the icon on top of the Answer box. And put it under the right category, not Gambling.

Bit too vague depending on room layout. Give us a rough sketch of the room and where you want the fixtures.

Typical 3 unit bathroom installation by UPC.
Minimum room / space requirement is about 5' x 8'

Black lines are drains
Red lines are vents


Toilet: 3" drain / 2" vent pipe - all the way through the roof ( that's your main vent )
Tub / Shower: 2" drain and trap, 1 1/2" vent, connect with toilet vent about 48" high from the floor
Sink: 1 1/2" drain and vent, connect with toilet vent about 48" above the floor

Run the common 2" vent pipe all the way through the roof, and terminate not less than 12" above the roof

Hope that helps
