Residence Hall - A and B unit Toilet and Bathing Areas

[Thomas Hofman]

I have seen some plans for new residence halls that look like they might have non-compliant toilet areas. I have always thought that B units had to be laid out so they could be converted to A units as necessary. To be convertible, they would have to be designed with a toilet, shower, and lavatory all meeting clear floor space requirements and door swings. Because of this, it tends to make the size of the room and the configuration of the fixtures more like a Type A unit than a smaller 'anything goes' residential layout. Is this not true?

Followup question....In a Type B unit; Toilet and Bathing Area, Option A, is the lavatory permitted to be outside the room with the toilet and shower. I am planning to build a sink area next to the closet storage which is next to the 48" wide compartmentalized toilet and shower room.

Thank you in advance.

If you are referring to A117.1 you need to provide type A units and type B units as scoped in the building code. Type B units are not required to be convertible to type A.

I'm sorry, yes I am referring to A117.1., specifically Section 1104.11.3.1 which points out the clear floor space at each fixture. It appears that all these clear floor space dimensions allow them to be convertible in the future (with of course blocking in the walls). I'm wondering if anyone sees any apparent issues with the drawing I attached in my first post, or if I have allotted too much unnecessary space for the bathroom layout. Also, thoughts on the sink being outside the toilet shower area would be helpful. Thank you.
