I'm pregnant and a colleague is about to return from mat leave. We've been discussing the room offered to my colleague for expressing milk when she's back. It's a clean and tidy shower room that you access through the client toilets in our office. The shower room has a separate door so there are two doors between the shower room and the loos. Is that okay from a health and safety perspective? The facilities manager has said that he can put a chair in the shower room without issue and there are already surfaces there for fiddling about with bottles and the like.
