Can one toivel keilim in a standard men’s mikva?
Toiveling keilim needs a mikva d’orayso on the level of a womens mikva. If the men’s mikva was made on such a level then it is alright. You should ask the people that run the mikva if it is good enough for keilim. For example a men’s mikva can from “zochalim”, but a keilim mikvah should not be from zochalim.
