I was doing this for several months. I remember the biggest drawback was that cold water does not dissolve soap and shampoo as well as warm does, so it takes more effort to wash yourself well.

I stopped because I got sick, and never got the habit back.

I do hot-cold-hot, so: stage 1: hot, get clean (soaps) stage 2: cold (focus, empty mind, ~1m) stage3: hot (reset, new day feeling, sometimes I save hair conditioner for this step, ~2m) My showers take ~10m.
