Barb, you didn't give a wire count or the actual dimensions of the box so it
is difficult to guess exactly what is permitted.

I have been in similar situations and have an easy solution. Install a 4
gang box.(Or a 5 gang) that will give you the additional cubic inches that
you need (See table 314.16(A) in the National Electrical Code. When you are
finished and have only 3 switches, buy a four gang wall plate that has 3
toggle openings and one blank. Or you can get a 4 gang toggle wall plate
and get a blank filler for the fourth gang. You will probably need to go to
an electrical supply house for this as I don't think many hardware stores
carry this set up.

A junction box must be accessible without damaging the wall. You could have
a recessed junction box be accessible from the other side of the wall if it
happens to be a closet or a room where it doesn't matter.

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.
