Looks like you have a good plan for the water.
When they get wet its normal to look like there is bald areas. Once they are dry and fluffed up they look normal again.
And i also bought a second rubbermade and cut the sides off and connected them. Because even with a diff waterer they still will get their bedding all wet.
So i connected mine and kept food and water on one side and the heat lap on the other with still one side cool. So one side always stayed dry and the water side often wet but i changed the bedding once a day.
