This is similar to the "shower closets" we used, although there would be a plastic swivel door at the entrance of the shower. When closed, this door just looked like another closet in the room. There was a separate door for the toilet and sink.

Because of this experience, I encourage – no implore – you to never use a shower closet in your bathroom.  Instead allow your personality to be your master bedroom’s saving grace or to spark interest in your guest bathroom.  A black and white shower curtain or double swag shower curtain are particularly our favorites for a master bath.  As for a guest bathroom we recommend either a funky unique shower curtain – one with stripes, polka dots, or geometric shapes – a horse shower curtain, or a beach shower curtain.  All of these are great options, clearly can establish your personal style and taste, and is hands down more refreshing than a shower closet.
