It depends on how big you are going to get, there should be a big place in front of the door, the traffic should be big, the equipment, if it's just a car wash, a car wash machine, a foam machine, a vacuum cleaner, towels, a car wash liquid 。。。。。。, you can go to one, that would be better.

You can go to a place that will be better I don't know where you are, but if you are doing it yourself, a storefront of less than 100 square feet will do, I hope that helps you
