Fermenting lager in water bins?

[Shoemaker]

I've heard of this but wondering how you guys do it. I've got a basement in the 60s range now and I'm planning on brewing a lager tomorrow.

How do you guys keep a constant temperature in these water bins? Anything else I should know?

It's not easy, but it can be done! You want to keep your water bath at 50 degrees or so- float a thermometer in the water bath to check the temperature. You can add a frozen water bottle (or exchange them) if you get above 50 degrees in the water bath.
