"RBM assumed you were describing a 4" square box as:

(this one has the side mounting bracket he described) with a raised
cover as:

which seemed to fit your description. He suggested a single gang
mudring
for a concealed 4" square box as:

A 4" square box gives you a lot of volume. "


That's what I have in my basement, where I use surface mount wiring
components. That would look terrible inside my bathroom wall. I was
asking fi there is a way to center it and have it completey inside the
wall.

Square boxes and "plaster rings" are a common standard method of installing
both exposed surface mount and concealed wiring when conduit is used. When
installed inside the walls only the outer face of the plaster ring is at the
surface and that is covered by the standard installed device and cover.
Finished appearance is no different from using cable and common outlet
boxes. When surface mounted a different type of box cover can be used with
the devices being secured by the cover only.
