I'm wiring some extra outlets and another set of lights into an already
existing circuit in my bathroom Previous wiring went from a light
swith on to other lights/outlets in other rooms. My issue is that
there will be so many connections in the swith box that I don't think
they'll all fit. It will be a 3 gang switch box with 3 more lines
(besides what the swithes go to) going from it. If I put in a juntion
box, can it be covered with sheetrock? Right now I have a section of
wall open, but I don't want to have a junction box visible on the wall.
Attic is accessible, but not easy. This wiring is a long, long way
from the attic opening. Wiring is 14 and 12 gauge.
Thanks.

Since your wall is open you can install a 4&11/16" square by 2&1/8 inch
deep box with a plaster ring that will give the same surface opening as
a 3 X 2 inch device box. Since that deep "11B" box can hold something
like 21 #14 AWG conductors I would think that might do it. Tell us how
many wires of what size that the box must contain and we can be of more
help. Each yoke or strap that supports a device such as a switch or
receptacle counts as two of the largest wire that terminates on that
device. All of the equipment grounding conductors count as only one
wire. Internal clamps count as one wire. #14s need two cubic inches of
space each and number 12s need 2.25 cu inches each. A deep 4&11/16"
square box has about 43" cubed of internal space.
