AMC 25.788(a) Installation of Showers ED Decision 2017/015/R The following should be considered in the design of a shower installation: (a) An analysis should be performed to identify possible failures leading to water leakage, and to show that appropriate mitigation features have been included in the design. (b) The shower cubicle should be considered as a passenger compartment in terms of the need for ventilation. The applicant should justify that adequate ventilation is provided within the shower. The cabin air itself can be considered as a ‘fresh air’ source for the air supply of the shower. (c) The shower cubicle air outflow should be directed into aeroplane areas that will not be adversely affected by the high water content of this air flow. (d) A means to steady oneself could be either (a) firm handhold(s) specifically designed and provided for the purpose or an intrinsic design feature of the cubicle. For instance, if one or more of the cubicle wall-to-wall dimensions does not exceed 1 metre (3.3 feet), it may be assumed that an occupant can steady himself/herself by placing his/her hands on opposite wall surfaces. (e) If electrical power outlets are installed in the room or area where the shower is present, all the following requirements should be fulfilled: (i) the shower cubicle should be enclosed up to the ceiling; (ii) there should be no electrical power outlet inside the shower cubicle; and (iii) no power outlet should be placed closer than 0,6m from any point on the surface of the closed shower door.
