I don't really have the space to put it into a water bath but I will try a thermal blanket and get a thermometer to monitor the internal temp.
I have my fermenter in a water bath in an igloo cooler right now, to help slow any temperature changes. You wouldn't need much room- My cooler is not much bigger than the bucket alone.
A blanket would help, though!
