COMMISSION AGENDA – Briefing Item No. 9a Page 2 of 3
Meeting Date: February 26, 2019
Template revised September 22, 2016.
In addition, on December 4, 2018, the working group conducted a focus group with faith-based
community stakeholders. The feedback from stakeholders helped inform the recommendations
included in the plan.
In January 2019, the working group received a layout study from consultant Architectural
Alliance International on Sea-Tac’s restroom program and how all gender restrooms might be
incorporated into the program. The study provided information on potential locations at Sea-
Tac where all gender restrooms may be added within the current footprint. In addition, a cost
estimate was also provided to the working group.
KEY HIGHLIGHTS OF THE PLAN:
Recommended Design for All Gender Restrooms in Existing Facilities
Compartment design: The compartment design features compartments that have a toilet and a
sink (accessible and non-accessible versions) with full height partitions and doors.
Potential Locations for All Gender Restrooms
Single-User All Gender Restroom Design and Signage
1. GATE D Head – Add one (1) single-user All Gender Restroom using the recommended All
Gender Restroom design and signage. This can be incorporated in the current restroom
renovation project.
Single-User All Gender Restroom Design without Signage (Future-Proofing in current space)
1. GATE B3 – Convert one set of restrooms to single-user All Gender Restrooms using the
recommended compartment-style design. The signage will be gendered (male or
female) to accommodate the building code requirements. The gendered signage can be
replaced in the future to the recommended All Gender signage once code is updated.
2. GATE C2 – Convert one set of restrooms to single-user All Gender Restrooms using the
recommended compartment-style design. The signage will be gendered (male or
female) to accommodate the current building code requirements. The gendered signage
can be replaced in the future to the recommended All Gender signage once building
code is updated.
3. GATE D3 – Convert one set of restrooms to single-user All Gender Restrooms using the
recommended compartment-style design. The signage will be gendered (male or
female) to accommodate the current building code requirements. The gendered signage
can be replaced in the future to the recommended All Gender signage once building
code is updated.
Recommended Signage for All Gender Restrooms
Plumbing fixture icon: The iconography of the western-style plumbing fixture of a restroom is
gender-inclusive and universally recognizable. The icon of a toilet is recognizable to both
international and domestic travelers. Focus group members were in favor of depicting what
was behind the door as it is clear and does not designate who can and cannot use the restroom.
