In soaking Sesh for mites (and those are LONG soaks) she's good at 83 - left the temp probe in there last time and the tupperwareadjacent to a heat lamp so the water wouldn't cool off too much. Again in agreement with Will - you should be upgrading the size of the water dish in synch with hide and enclosure sizes - they should always be able to comfortably get all the way in their water for a soak should they be so inclined.
