Rule of thumbMandatory
Shower in a corner or wet-wall enclosure
FIX-SHOWER-WALL-01Description
Shower stalls must be aligned with at least one wall. The shower enclosure is framed against the wall plane and waterproofed at corners; a shower floating in the room center cannot be framed.
Why this exists
Showers need at least two walls for plumbing access + waterproofing. A shower in a freestanding wall is structurally and economically worse.
