While the phone is not really waterproof that term has become almost interchangeable with the correct one which is water resistant. If you want your phone to be "like" new after it has been repaired you should always replace this front assembly adhesive.
iPhones has become slightly more complicated when it comes to replacing a broken screen. The main differences are the additional of yet another proprietary screw, the Y000 Tri-lobe used on the inside and the addition of a water resistant adhesive that holds the front display assembly in place. On top of that the cables are thinner and more fragile than ever before so while this can be a DIY repair it may be better to seek professional help if you don't already have plenty of iPhone repair experience.
This model opens from the side similar to the iPhone 7. There are several clips at the upper end of the screen though so it must be slid down a bit before you can open the screen up.
The connectors are also very fragile so care must be taken when unplugging or connecting them. They bend easily too so you have to be sure that even pressure is applied since pushing on just the center can cause them to warp. If the front facing camera flex cable is plugged in upside down you may end up with post repair complications so it is important to note the orientation of this cable during disassembly. The home button is another troubling factor as damaging the secure enclave or anything attached to it may render Touch ID inoperable and this is not a component that can be replaced by third parties in order to restore functionality.
After market LCDs for the iPhone 8 Plus are now available and for most consumers make are a good option if they wish to save some money or expect the screen to be broken again in the near future. It is also possible to acquire OEM replacement screens although they will cost more and in most cases are actually fitted with after market glass. Tempered glass is always a good investment and can restore that "smooth" feel in the cases where an after market screen replacement part lacks an oleophobic coating.

Note that while it is often considered best practice to use an ESD safe pry tool when performing an iPhone 8 screen replacement we opted for precision tweezers this time to demonstrate how easy it is to damage components when prying with a plastic tool or fingernail. Given the level of precision required to replace an iPhone 8 display it this should not be a concern for capable parties. Just be sure to always carefully disconnect the battery first and watch out for small components in close proximity to the connectors.
