Tubs just substitute one issue for others especially in single snake set ups that are in normal rooms with normal room temps. Tubs heat very easily but they loose heat just as easily they can be very hard to hold ambient and cool end temps. Typically they only hold a degree or two over ambient room temps. If your room is 80 that is perfect if not it can be a problem.

Bigger water bowl and substrate choice can make a huge difference. I found that using coco coir substrate. Under the coolside I would a bury a plant saucer filled with water dry coco on top. This would increase the rh a bunch. Every week or so I would dig though the thick cool end substrate and fill the bowl. The hot side substrate is quite thin.
