What Experts Say
According to water quality experts, the key difference lies in contamination risk. If your bathroom water supply comes from a cold-water storage tank rather than directly from the mains, it may be more susceptible to:
Bacteria growth: Especially if the tank isn’t sealed properly or cleaned regularly.
Lead or metal leaching: Older plumbing systems can release small amounts of metals into standing water.
Stagnation: Water that sits in pipes overnight or for long periods can develop a stale taste and harbor microorganisms.
The kitchen faucet is where most people fill drinking glasses for a reason—it’s the most reliable source of clean, potable water in the home.
My Experiment: Proving My Point
One night, after my husband took another lazy sip from the bathroom tap, I decided to test his theory.
I filled two glasses—one from the kitchen, one from the bathroom—and set them side by side. The difference was subtle, but noticeable.
The kitchen water looked crystal clear. The bathroom water? A faint cloudiness, almost invisible unless you really looked. I tasted both. The kitchen water was crisp and fresh, while the bathroom one had a slightly metallic tang.
When I told him what I found, he rolled his eyes. “You’re imagining it,” he said.
