Except from a civil engineering perspective this makes no sense at all. Bricks are not laid in a single layer like that unless the wall is exceedingly short (serpentine wall as a fence) or unless there is a structural backing like an interior load-bearing non-brick wall.
And most all-brick walls in a structural capacity (meant to carry the weight of a structure) are dual or triple walled, depending on the height of the structure and the load bearing requirements.







Sorry, are you talking about showers with broken doors, or showers without a door at all?
If the latter, how TF is that supposed to even work? Are we talking like a communal shower, where the door is too far away from the shower for water to splash out?
