How big is the area of the hotel public toilet?

In the plane design of public toilets, toilet rooms, urinal rooms and bathroom rooms should be set up, and each room should have independent functions. The urinal should not be set in the open air. Yin and Yang channels should be set at the entrance of the bathroom to block the walls or objects. Each toilet should have an independent unit space, and the distance between the partition and the door separating the unit space and the ground should be greater than 100mm and less than 150 mm, and the height between the partition and the door and the ground: for Class I and Class II public toilets, it should be greater than 10.8m, and for Class III public toilets, it should be greater than1.5m.. Independent urinal stations should have a height.

The ventilation mode of public toilets should be reasonably arranged, and the air exchange rate of each toilet seat should be not less than 40m3/h and that of each urinal should be not less than 20m3/h, giving priority to natural ventilation. When the ventilation is insufficient, mechanical ventilation should be increased. The ventilation frequency of mechanical ventilation should reach more than 3 times /h, and when mechanical ventilation is set, the vent should be set above the squatting (sitting and standing) position1.75m.. The urinal shall be a front flush squatting pan with water seal function, and the urinal shall be a semi-trailer bucket. When conditions permit, the ventilation mode of single bathroom exhaust can be adopted.

The indoor clear height of urban public toilets should be 3.5~4.om (it can be reduced appropriately when installing skylights). The elevation of indoor terrace should be 0. 15m higher than that of outdoor terrace. If the septic tank is built indoors or underground, the ground elevation shall be determined by the septic tank drain. Each toilet is1.00 ~1.50m long and 0.85 ~1.20m wide, and each urinal is 0.75m deep and 0.70m wide. The distance between independent urinals should be 0.70 ~ 0.80m.

The width of the aisle outside the toilet seat should be 1.30m, and should not be less than1.oom; ; The aisle width of double-row toilets should be 1.50 ~ 2. 10m. All kinds of public toilets should not be exposed outside the sight of toilets, and there should be partitions between toilets. The trough depth, trough bottom width and upper width of the toilet should be not less than 0.40m, 0.15m and 0.20 ~ 0.25m respectively. The minimum height between the window sill of a single-story bathroom and the indoor floor should be1.80m; ; The minimum height between the upper windowsill and the ground of double-decked public toilets should be1.50m.

When there are more than 20 toilet seats in men's and women's toilets, it is advisable to set up double entrances and exits. The area of toilet management room should be 4 ~ 1~2m2, and the area of tool room should be 1~2m2. Trough-type public toilets should be flushed by men's and women's toilets in separate troughs. When the sink is used together, it must be flushed from the men's toilet to the women's toilet. * * * The entrances and exits of men's and women's toilets must have obvious gender signs and should be set on fixed walls. In places with higher requirements, public toilets can be equipped with a third toilet. The third bathroom should be set up independently, and should have special signs and instructions.
