I've never used water as a stop bath, because it really doesn't stop the
development, but slows it down.  When developing film, I feel the need to
stop the development precisely.

However, if you insist, water can be used as an intermediary step between
the developer and the fix.  The problem is that not using a real stop bath
will definitely reduce the capacity of your fixer.  The stop bath not only
stops the development, but also neutralizes the components from your
developer, thus extending the lifetime of your fixer.  Not using a stop
bath really isn't the recommended practice.
