Leave the massage room and take a right. Go into the first door on the right with a tanning bed. Stop and the foot of the tanning bed.
Exit the beginning room and enter the open area. Turn right and enter the farthest right room. Stop right in front of the table.
Turn to the left, walk between the massage tables. Go out of the door, and straight just a little way and turn right. You'll see a big bathtub-like thing. You'll stop right there.
