I have mine on carpet, doesnt hurt anything. When you spill water, you just soak it up. But a bit of advice from my last couple days.......if it is on the 1st floor above your basement, make sure it is not above your furnace. I had a little bit of water overflowing, it soaked down through the floor boards and landed on the furnace......guess what is bad for electrical work, saltwater. cost me $250 to get the electronics repaired.....may sound stupid, but just some consideration
