Facing into a bedroom with a bed on the left and a red, purplish wall on the right, turn to the left, in the distance you should see a room with some orangeish wall paint. Head towards that open door with the orange wall. You'll see white tile on the ground in that room. Enter the room. It's a bathroom, walk towards the bathtub. In front of the bathtub, turn to your left and walk to the left side of the sink. You're standing just about to enter the shower to the left of the sink, you're done.
