How much space should be between shower door and wall?
Generally speaking, we aim to have 1/8” gaps between the glass and the tile. Where the hinge side of the door meets the wall a 1/4” gap is normal. You have the back plate of the hinge, which is 1/8” thick, and the additional 1/8” clearance there.
What is code for toilet clearance?
Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture. (The NKBA actually recommends 32 inches.) There should be at least 24 inches of clear space in front of a toilet or bidet.
