Hi. New to DIY Forum. Home built '83. Main bath has a 1-gang receptacle

[RAGBJG]

Do I secure an additional 1-gang pvc box to this original 1-gang box or do I have to somehow remove the 1-gang box from the stud and install a new 2-gang box. I'm trying not to destroy the drywall and if I can secure a new 1-gang to the old 1-gang, will the 2-gang wall plate fit ok or will there be too much width using two separate boxes?
Thanks,
Bob

I believe from your location, that’s an American zip code.

If @Megawatt could answer this one?

Photographs may help from the OP

You don’t have a choice, either way you will have to cut the drywall to add a different box. Use a 2 gang box not 2 single boxes

Not seen many baths with a one or even two gang receptacle?

He’s probably wanting to add a light switch or GFCI or RCD outlet as y’all call it
