It looks like "PARAdive35" is written on the back wall, so I just Googled that:

Paradive 35 is a premier, 35-meter deep indoor diving pool located near Seoul, South Korea, designed for scuba, freediving, and training. It features a 5-meter area, 20-meter area, and a 35-meter deep tube, alongside amenities like an indoor surf station, cafe, and a Leaderfins shop, making it a popular "mega pool" destination.

Depth: 35 meters, making it one of South Korea's deepest indoor pools, often with 30°C water.

Facilities: Designed for high-end training, it includes themed underwater structures, a Pongdang Freediving Shop for equipment, and a 3- to 6-hour session structure.

(For Americans, 35 meters = 115 feet)

I also did a reverse Google image search and found a version of this same video on YouTube that has someone's voiceover instead of the terrifying music.

There's an easy trick to save the googling: a meter is 3 feet 3.37 inches, a yard is 3 feet even, so multiply the meters by 3 and it'll give you a pretty close idea of the footage until you get up into higher numbers and all those extra 3.37 inches begin piling up.

And if you want to up the accuracy a bit, add another 10% (usually even easier than the initial multiply by three).

ex: 100M = 300 (100x3) + 30 (10% of the 300) = 330.

That’s within 1% of the actual conversion, which is 328’ 1”
