Queen steet station and Glasgow central station
Grand Central Station & Terminal are located at East 42nd Street between Park and Lexington Avenues. Grand Central Station is the subway station, where you can catch the 4-5-6 (the dark green line, aka the Lexington Avenue Line) or the S shuttle train to Times Square. Grand Central Terminal is the railroad terminal, for trains that are not part of the New York City subway system (like MetroNorth commuter trains).
According to Wikipedia and the MTA themselves, 77 of New York City's subway stations have working bathrooms, and 28 of these stations are in Manhattan. However, according to the Related Link (see below), in Manhattan, only 8 of these stations are actually functioning and open to the public (9 including "the developer-financed wonder bathroom at the Times Square Station"). The only one on the 6 line is the Brooklyn Bridge-City Hall Station. There are also bathrooms at Grand Central Terminal, downstairs, near the food court. The 4-5-6 line stops at 42nd Street-Grand Central Station, but Grand Central Station is the subway station, while Grand Central Terminal is the railroad station. So, you would have to exit the subway system to use the bathroom, and then pay another fare to get back on the subway.
