Question: What is the required depth of mikvah waters?
Short Answer: Water in a mikvah must be a certain height above the middle of the immerser’s body. Accordingly, many mikvaos are approximately four feet deep.
Question: Should observant Jews strive to build mikvaos in non-observant communities? Should a mikvah (run by observant Jews) allow non-observant Jews to use the mikvah for conversions?
