Where do I change Rotom's form in Omega Ruby and Alpha Sapphire?

Question

Need a wash form one for my competitive team.

Answer 1

In the professor's laboratory back in Littleroot. In the south east of the lab you will find a bunch of cardboard boxes. Interact with them with Rotom in your party to change its form.

Hope I helped. :)
