If you live in New York it is an average price (sadly) All the requirements for workers comp insurance, liability, insurance to cover tools, permit fees (yes in NY you cannot get a permit without showing proof of WC and liability now)

I bought a thankless sized for two bathrooms, a dishwasher, and a clothes washer on amazon for $550.
