How much does it cost to just use dog wash station with my own dog shampoo?

I think you can start the machine for as little as $1, same as the car wash.

Yes Aaron Lewis is correct, we start at 1$-1 minute then we have bonuses once you get to 5$, you'll get 6 minutes all the way up to 10$ for 14 minutes. As for how much it will cost you, using our shampoo and dryer it costs me 10 - 12$ to wash my 80 pound chocolate lab. After you put money in it will continue to count down no mater what function you are on, or if you are on stop. That being said you can start the timer for a couple bucks get the dog wet, use your soap, and then restart when you are ready.

So is it on timer like car wash? I mean if I wet my lab and not use water until rinsing still counts minutes in between?

I don't know I only used the car wash
