Probably the sent of the bathroom is different from that of the kitchen and interferes with your taste buds especially if you just took a big steamy dump.

You know these stories I keeping hear from people are getting more and more ridiculous.
They just don't add up ?
The stories online and the people right in front of my face. If your going make up a story at least have it make a little sense, do some research!
I just didn't fall of the cabbage truck :)

I just can’t bring myself to drink from bathroom taps. Sure, I use it to brush my teeth, shower etc but I draw the line at ingesting the water

Your name doesn't start with an R does it? If it does I think you were complaining about this well over 20 years ago.

Has anyone looked up what's in the "safe" drinking water we all consume ?
Bathroom or kitchen it's all poisonous !
And if you live in an older building which a lot of people do you have the lead pipes wrapped in asbestos for the "healthy" tap water to run thru.
Yummy lead, metal's , rust, fluoride, arsenic. bacteria.
Hate to be the bearer of bad news.
