2. Bathroom layout: A complete bathroom should have the functions of going to the toilet, washing, bathing, changing clothes, washing clothes, drying clothes, making up, storing toiletries and so on. The most basic requirement of the bathroom is to reasonably arrange the "three big pieces": the sink, the toilet and the shower room. Sometimes, some cleaning tools in the family are also included, such as the placement of washing machines, the mop pool (considering cleaning dirt), daily necessities and the storage of cleaning tools. In the architectural design of the bathroom, the launching position of the "three big pieces" has been arranged. Don't change the launch position easily unless the position is insufficient or the design is unreasonable. The basic layout method of the "three big pieces" is from the outside to the inside: starting from the door of the bathroom, it is ideal that the sink is close to the door of the bathroom, the toilet is close to its side, and the shower room is set at the innermost end. This is good function, good function and good appearance. The design of the washbasin cabinet depends on the size of the bathroom. At present, the general area of the bathroom is about 3-6 square meters. A certain aisle and activity space should be reserved around the washstand in the bathroom. For a 5 square meter bathroom, 1.0m long and 0.6m wide washstand is enough. A silver mirror and a mirror headlight should be designed above the sink, and the mirror is generally designed to be as wide as the sink.
