The useful question is whether a cloth or mop can reach the whole floor, including the corners between fittings. In our Bridge of Don ensuite, a long shower sits alongside wall-hung furniture, with the floor beneath the basin and toilet left accessible.
We follow the cleaning route from the doorway to the far wall and check the gaps beside the furniture as well as the space underneath it. Draw in the bath mat, basket and scales where they would normally sit. Give those things a place that leaves the mop a clear route, particularly at a narrow turn beside the toilet. A reachable patch under the vanity is more useful when you can clean it on the same pass as the rest of the floor.
