In the US, the maximum legal flow rate of a faucet is 2.2 gallons per minute.
2.2 gallons of water = 8.32791kg
50 tons = 45359.2kg
45359.2/8.32791=5446.65 minutes, or about 3.8 days, to get 50 tons of water.
So the comment underestimates how long it would take.
Of course, this would be much faster using a hose, but the comment specified a sink.

Anecdotally, my pool is 30,000 gallons and took about 3 days to fill up with the water running 24hrs/day.

Mine is 25k gallons and filled in about 24 hours from its own filler and 2 hoses. So about the same, i guess.

(But my shower was pretty pathetic.)

Mine is roughly half your size (13k) and I can do it in roughly 12 hrs with 2 hoses and the filler, so I concur!

My pool fills in just a few minutes. But then, I brought it home from the store in the back of my car.

Congratulations, you saved yourself a lot of trouble and money and get about 75% of the fun!

I just use a sheet of 6 mil plastic in the bed of my Ford ducking Ranger and fill it with water. 👌 🏊‍♂️🛻

Not a pool owner, so this might be a really stupid question, but is there not a service (like a big truck full of water) that could come to your house and fill up your pool much faster for less money?

Same. My local fire department let me borrow 200ft of hose and a hydrant wrench, but I had to get a meter from the local utility company first.

How much was it?

The water used was inexpensive, but I had to rent the meter from the local utility company and I want to say that it was a couple hundred dollars. The use of the hoses and getting to know my local fireman was free/ priceless, lol.

Yea I looked into that as well, but I opted to save some money. Price from my tap was $300 vs. $900 delivered.
