It gets harder as they get older
If (or I should say when :LOL) I am faced with these scenarios I try to find a way for dc do do what they want (dump water on the floor) while getting what I want (no water on the floor). If it was my ds (when he was that age) I probably would have explained that water on the floor can make it slippery and dangerous then found him another container to place outside the tub to pour water into. He has fallen on wet slippery floors so he would have understood. When he was finished the bath I would have handed him a towel to help mop up the excess water. Not in a "punishment" kind of way, but just, "here ya go, lets clean up the water." matter of fact kind of way.
This approach almost always works. Keeping things fun and light-hearted makes such a difference. The challenge (for me) is having the energy and the right frame of mind to come up with creative solutions
