Cracked Galaxy S7 Edge

[Driver101]

I managed to drop the phone at work today. Even in the case it must have caught the bottom corner of the screen. I'm left with a little spider in the bottom corner and a few longer cracks across the screen.

It's not hugely noticeable and everything still works.

What will it cost to fix? Will it still be waterproof?

I've got insurance through my bank. It's £75 excess but I notice they supply refurbished handsets. Will they still be waterproof if the screen has been replaced?

I called the Samsung repair centre and was told it's
£250. They also said that they can't keep up with broken screens. There's a few more due in before the week is out, but they will go very quickly and I'd need to reserve one.
