Water damage repair

The cost will vary depending on the extent of damage. It will likely be hundreds of dollars, since the reduced charge if you had AppleCare+ would be $300. Apple will provide an estimate before you decide whether or not to have it repaired.

yes—If you have AppleCare+ it will cover a large portion of accidental damage.

AppleCare+ (similar for iPhone and iPad, each incident of accidental damage) for Mac will carry its own price tag. Screen damage or “external enclosure damage” will run $99 per incident, while other damage, including water damage, will run $299. Users receive coverage of two incidents under AppleCare+, and after the two incidents have been used up, out-of-warranty replacement rates will apply

(*note: there may be some delay due to the temporary Apple Store closures)

Unfortunate. 😢 The basic warranty, no. If you bought AppleCare+, it will cost $299 for the repair.
