Cold-crashing in a refrigerator, bathtub, outside, or someplace other than where you intend to do the siphoning is not the best advice.
If at all possible, set your fermentor at counter height in a cold, sub 40F basement or garage for the length of the cold crash (about 4-5 days). That way, when it is time to siphon, you don't have to move the fermentor and stir up the trub, thus negating the whole benefit of the cold crash.
