You said regarding a home mikvah for toiveling,
If you can fill it till the mouth of the faucet is in the water, then we might have what to work with.
Fill a large enough bathtub....
A piece of rubber hose attached to the faucet?
How big a bath tub?
Do yo approve of a jaccuzi for toiveling if it`s at least 3 1/2 feet deep and seats 10?
