The National Capital Mikvah is happy to assist brides and grooms before their wedding date. Women should make an appointment as normal, but should book a 1-hour bath appointment so that there is time to learn the process without feeling rushed. Men should email at least a week prior to their wedding date, so that a shomer can be arranged. Grooms use the mikvah during the day, typically just after shaḥarit (morning services).
