Until the 1950s, Jews of all denominations were generally allowed to use the same communal mikvaot (ritual baths) for the purposes of converting to Judaism, observing the rules of niddah in regard to laws of marital purity, ritually cleansing dishes, etc. However the Haredi movement increasingly denied the use of mikvaot to non-Orthodox rabbis for use in conversions. According to Walter Wurzburger, Soloveitchik counselled Orthodox rabbis against this practice, insisting that non-Orthodox have the option to use mikvaot (Wurzburger, 1994).
