Moen isn't the only one trying to change the shower game. 
French company Smart and Blue showed its Hydrao range of showerheads at CES. They're kitted out with LED lights that change color, from green to blue to purple to red, based on how long you've been showering. The aim here is to cut unnecessarily long showers short, saving you money on utility bills in the process. And you can turn it on without getting out of bed.
Available for preorder in the US now.
