A standard bathroom faucet has a restrictor to limit it to 2.2 G/Min.
If you ran one faucet non stop, you would fill the pool in 208 days, 9 hours, 55 minutes.
Note, this does not account for evaporation. I am assuming you are filling a perfectly sealed volume, where every bit of water that evaporates condenses and drips back into the pool.
Other people have answered the OP's question well, but I want to expand on it a little.
One bathroom faucet (5.7L/min) would fill an Olympic-size pool (2.5 ML) in 304.6 days.
However, there are 325.7 million people in the US. If each of them brushed their teeth for 2 minutes, twice a day, and left their faucets running the whole time, we're looking at daily wasted water in the US of 2 * 2 * 5.7 * 325.7 = 7,425.96 million liters. That's equivalent to 2,970 Olympic-size pools filled up in one day.
TL;DR @WinslowDumaine needs to stop trying to be clever, and learn basic arithmetic.

Olympic-size swimming pools contain 2,500,000 L. A bathroom faucet delivers 5.7L/min or less.
It would take 2,500,000 L / 5.7 L/min or 438,596.5 minutes. That comes to 7,309.9 hours, or 304.6 days.

An Olympic pool has 660,253.09 gallons of water.
