Toilets are not typically electrical (I know there ARE electronic toilets, but they're far from the norm) so I would not like that. Rotom should stick to common electrical devices.
I'd also really prefer Rotom to not get new forms in general. Rotom forms were a neat idea, but there are already a lot of them and I don't really feel like they need to go back and add even more. I'd rather they make brand new pokemon with unique Electric type combos rather than using Rotom as a way to add some lackluster Electric / Whatever combos. Especially since Rotom forms only learn 1 attack of their respective type, which makes the secondary type seem more tacked on than anything (IMO anyway, I preferred when all Rotom forms were Electric / Ghost when the bonus move was just that, a bonus, rather than having them change type and having it feel very limited).
