I have a half bathroom in my basement. I want to remodel the bathroom and add a shower, so I'll need to bust up the concrete floor and tie in the new shower drain to the existing drain line in the floor. Problem is, I don't know where exactly I will need to bust up the floor. I could do the whole floor, but obviously the less the better. So I was wondering if there was a way I could snake something "snake-able" down the toilet drain, and then use some sort of locator to wave over the floor that would beep when it's directly over my snake, and then I can mark it at different "depths", therefore showing me exactly where the drain is running under the floor.
Is there such a thing? It seems like a very simple concept and I don't see why something like this wouldn't exist for a reasonable price. This way, I'd only have to chip up the floor where the shower is going and where I'll be tying into the existing drain line. Any thoughts?
