Some films are more sensitive to temp changes than others, so I err on the safe side and temper all my liquids the same.
A. In thousands of rolls of film I have never had any problem with wash water or stop water being a different temp than developer. Nor have I ever checked the temp on wash or stop other than to see that it was not hot.

B. Toss a few ice cubes in a ziplock bag and use that to lower your developer temp.

C. Use Diafine, or some other developer that is either temperature independent or that is a higher temp developer with a development curve that goes through your normal water temps.

D. Just use bottled water.
