Even if the Mikvah wasn’t used most of the year, the expenses I listed would exist.
An organization would not dare operate without insurance, both liability for slips and falls, etc. and casualty….fire, theft, a tree crashes through the roof, etc.
Towels need to be purchased and cleaned, soap, shampoo, etc is needed.
Especially if not used regularly, deep cleaning is required. Have you ever opened up a bungalow or winter vacation home after a long absence? Dust, dirt and dead inssacts will be there, no matter how well you cleaned before leaving,
Utilities>>>you still need water, maybe air conditioning, a heat source for water and building, electric lights, etc. Here in New England, you must heat to a minimum of 50 degrees F in the winter or risk freeze damage to the water system
Payroll….who cleans and fixes for free?
Upkeep? it will need painting every so many years, grout needs cleaning, rubber flappers in the toilets need replacing
To the best of my knowledge I don’t know CT Rebbe…………………
Pricing is based on 2 things: supply/demand and opportunity to raise funds. You might ask why a Kallah is charged 3 or 4 times the regular rate before her wedding compared to what she’ll pay afterwards.
BTW>>>>OOT most communities have only 1 or 2 mikvaos. In our area there are set fees for women, but just a place to leave a donation for men.
