From the support plan for implementation:
The truth is, from a numbers perspective, gay/straight interaction in bathroom facilities aren't treated by society like the distinction between male and female. There aren't separate gay/straight showers in public (or even on-base) gym facilities with no stalls or privacy curtains, but, amazingly, people manage to deal with it.
Services retain the discretion—as budgetary constraints and mission
needs permit—to modify facilities to provide one or more private showering/
changing areas consistent with current DoD design guidance. Small
modifications to improve privacy, such as installing privacy curtains where
feasible, can be accomplished at the unit level with little impact on the force.
As in civilian society, there will be locations, either at the fitness facility or in
the field, where privacy will be minimal. Members of the Military Services
must understand that the mission frequently demands operations in austere
conditions where privacy is not a concern to operational planning.
As with shower and bathroom facilities, the Working Group does not
recommend any new construction or modifications to facilities beyond low-cost,
unit-funded adaptations where appropriate. Existing design criteria are
adequate to support most billeting and berthing concerns in the the Department
of Defense. DoD Unified Facilities Criteria (UFC) require that all new permanent
party unaccompanied housing be designed to afford members private bedrooms
and bathrooms shared by not more than one person (the “1+1” standard). DoD
UFC will remain in effect regardless of repeal of 10 U.S.C § 654, as will existing
Service waivers or exceptions and Services’ ability to apply for such waivers and
exceptions. The continued construction of unaccompanied housing facilities in
accordance with the 1+1 standard, subject to Service waivers and exceptions,
will, over time, provide greater personal privacy to Service members as
budgetary constraints and mission needs permit. Regardless of the availability
of individual bedrooms for Service members, such construction would not affect
berthing or billeting in deployed or shipboard environments.
