When we put together plans for small projects people often ask “why are you putting in a drinking fountain and a janitor’s sink?” The answer is pretty simple, even on small projects they are required by the International Building Code.
Whatever the size of your project, unless it is a residential project or in a covered mall, count on having a janitor’s sink and a drinking fountain within the space. The total number of these fixtures will grow if your space grows, but it never goes away.
