This is mainly a UK based site - that said - I normally have my strawberries outside in May here and leave them outside all summer - I have left last years plants in a pot outside all winter and they have produced a good crop this summer.
My instinct says no to the shower room option but yes to option number 3.
Im sure someone more experienced than me will offer some great advice!
Good luck with the strawberries 😁
