The speaker doesn’t work. How can I fix that?

Hi Briann Bravo,

Was the phone dropped into the water or only onto the sand?

If only onto the sand then here is a link to the iPhone 6 Plus Speaker Replacement guide. This will help you to gain access to the speaker to ensure that it is still connected properly or if it has to be replaced.

If you have to replace the loudspeaker the part is available from ifixit. Here's the link iPhone 6s Plus Loudspeaker

If the phone was dropped into the water then follow the directions in this link.

How do I fix a salt water dameged iPhone 6 plus?.

Here's a link to the ifixit iPhone 6 Plus guides which may be of some help if you decide to do the repair yourself.
