The living room or lounge (= where you sit, relax, talk and watch TV); the dining room- the kitchen; the bedroom(s); and the bathroom(s). ’
Some people also have a study (= room with a desk where you work), a utility room (= a room usually next to the kitchen, where you have a washing machine), a spare room (= a room you don’t use every day. Often this is a room that guests can use), and possibly a playroom for small children.

I put the meat in the oven, put my dirty clothes in the washing machine, made the coffee and put the milk back in the fridge.
