DS: What do you give your dogs a bath in?

I've heard all kinds of answers to this one, because people use so many different things, I've even heard of people using their kitchen sinks...eww ( but that's just my opinion, not trying to be judgmental ) so..anyway what do you bath your dogs in? Tub, Sink, Kiddie Pool, Swimming Pool, Pond, Lake, Stream, Doggy tub ( if they have them ) Hose em down, wet em and scrub em down without any container or thing to place them in.? If you don't bath them do they go to the groomers.
