1.
bathroom; bathing room
A room containing a bathtub or shower for bathing.
浴室 is composed of 浴 (bath) + 室 (room). It specifically means the room for bathing, not the toilet. In casual speech, お風呂 is far more common.
Japanese bathroom layout
Japanese bathrooms are typically separate from the toilet room. The 浴室 contains a 浴槽 (bathtub), a shower, and a washing area outside the tub where you wash before soaking.
Register
浴室 is used in formal contexts — real estate listings, hotel descriptions, and written language. In daily conversation, お風呂 or 風呂場 is preferred.
