Regardless of your opinion on gender neutral restrooms, its true that they are becoming far more common than they used to be. Most consist of private toilet stalls with handwashing sinks in the common area outside of the stalls, but without urinals, you loose the benefits of urinals, both for water conservation, the space savings of urinals, and the speed of urinal use vs standard toilet stalls.
There's been a few solutions proposed for this:
While they provide the best privacy and urinals in separate stalls can help solve the water use issue, they doesn't solve the space use issue, and in practice has slower throughput of users than urinals that aren't enclosed in stalls.
Dual flush toilets in stalls conserve some water, but not as much as urinals. Users also often don't pay attention and just flush normally by default, and these toilets cannot be auto-flush causing a potential sanitation issue. They also don't increase throughput of users, but they do allow any user of the restroom to use any stall, regardless of if they need to just urinate or not.
A separate room for urinals keeps them separate from users who may be uncomfortable by the presence of people using urinals, and have all of the speed of throughput and most of the space saving benefits of the traditional urinals, but women may feel unwelcome or uncomfortable using these urinals in a separate room, limiting these benefits to women.
Urinals in the main restroom with traditional, or slightly larger than usual urinal dividers save the most space and are more welcoming for women to use since it doesn't involve entering a separate space dedicated to urinals, but they could make cause make women users of the restroom uncomfortable being around men using urinals.
