The US government is proposing a rule change that would allow showerheads to boost water pressure after President Donald Trump complaints.
The Department of Energy plan follows comments from President Donald Trump last month about increasing water flow for home appliances because he needs to keep his hair "perfect".
"We're bringing back consumer choice in home appliances so that you can buy washers and dryers, showerheads and faucets," he said at a White House event.
"So showerheads - you take a shower, the water doesn't come out. You want to wash your hands, the water doesn't come out. So what do you do? You just stand there longer or you take a shower longer?"
"Because my hair - I don't know about you, but it has to be perfect. Perfect."
Consumer groups denounced the plan, saying the Department of Energy's proposal is "silly" and that amid the problems the country faces, showerheads aren't one of them.
The new proposal would allow shower fixtures to include multiple shower heads that would get around 2.5 gallon (9.4 litres) per minute.
With four or five more nozzles, "you could have 10, 15 gallons per minute powering out of the showerhead, literally probably washing you out of the bathroom," said Andrew DeLaski, executive director of the Appliance Standards Awareness Project.
"Frankly it's silly," he told Associated Press. "The country faces serious problems. We've got a pandemic, serious long-term drought throughout much of the west. We've got global climate change. Showerheads aren't one of our problems."
"If the president needs help finding a good shower, we can point him to some great consumer websites that help you identify a good showerhead," DeLaski said.
It is uncertain whether the plan would be finalised but the proposal could face court battles if it advances, Reuters reported.
