NFPA 13 3.3.2 “two bathrooms can be adjacent to each other and are considered separate rooms, provided they are enclosed with the required level of construction.”
Taylor Schumacher From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Fox, Duane T. (FireMarshal) Sent: Monday, September 24, 2018 9:48 AM To: 'sprinklerforum@lists.firesprinkler.org' Subject: Omission of sprinklers in hotel bathrooms I have a hotel project where the designer has placed a door inside the bathroom between the sink and toilet/shower. The bathroom is over 55 sqft, however, with the placement of the door inside the bathroom each area on either side of the door is less than 55 sqft. NFPA 13 – 8.15.8.1 states bathrooms under 55 sqft are exempt (with other criteria met) and the appendix for that section states a door is not required in order to omit sprinkler as long as the bathroom complies with the definition for compartment. I assume the door in the appendix is between the bathroom and the living space. My question: is adding a door inside the bathroom, making two areas within the bathroom, a viable design to allow the sprinklers to be omitted? In my opinion the bathroom square footage is the entire area within the bathroom space no matter how many doors are used. Therefore, the space would need coverage. Duane T.
