In LEGO Fortnite, swimming and dealing with the oceans in general is rather arduous. If you’ve placed an item underwater, well, you’re in for a tricky time removing it.
The only way to get rid of items underwater in LEGO Fortnite
Before I tell you of all the ways I desperately tried to get rid of a built structure underwater in LEGO Fortnite, I’ll quickly spoil the conclusion. The only way that succeeded in destroying something underwater was by throwing an Boom Barrel at it.
You’ve got to be careful, as if you miss the target, and it doesn’t explode, it’ll uselessly bob up and down. Depending on the placement of the item, you can try to shoot the barrel with a recurve crossbow, and if it’s close enough, it may be able to blow up the object.
Ideally, you’d be able to trigger the barrel by it hitting the floor when it initially sinks, or by hitting the object itself.
Do not try any other method. It will not work.

What not to do when destroying an underwater object in LEGO Fortnite
The following methods will not work, so use my experimentations as guidance. If you want to try something that I’ve somehow missed, then go ahead, but it probably won’t work.
Dynamite, for some reason, disappears upon contact with water. So please don’t waste your dynamite. Also, Recurve Bows aren’t strong enough to deal damage to structures, which is generally useful, but an annoyance in this situation.
I also tried to make a car or vehicle to ram into the object, as I’ve found they’re great at destroying trees and rocks. However, upon loading up a dynamic platform with loads of large thrusters, it did not succeed in destroying the wall.
You could load up a dynamic platform with some Boom Barrels enclosed in a chamber and launch that full speed at a wall, but in that case, you may as well just throw the barrels yourself. The only situation that this could be useful is if you’ve somehow placed an object too deep or too far for you to hit it.
Oh yeah, and placing balloons on the thing will not lift it. Not even a tiny furniture item can be lifted by the Large Balloon.
