Why the Best iPhone 8 Plus Waterproof Case 2026 Matters
The iPhone 8 Plus (2017) has a 5.5-inch Retina HD display and dual 12 MP cameras. Many owners still love the Home button and the familiar size. A phone this age has often survived several drops, so sealing it against water is a smart way to keep it going.
Water is one of the most common ways older phones die. A single dip at the dock or a pocket in the rain can end a phone that is otherwise healthy. An IP68 iPhone 8 Plus waterproof case closes that gap for a fraction of the cost of a replacement.
Gorilla Cases builds this iPhone 8 Plus waterproof case with a compressing gasket and a snap-lock closure. The gasket works like a dry-bag roll-top, firm and even. For a modern waterproof comparison, read our Best iPhone 13 Pro waterproof case 2026 guide.
Waterproof Case or Screen Protector Only: What Does the iPhone 8 Plus Need?
A screen protector guards the glass but does nothing for water or for the body. A waterproof case wraps the entire phone and includes its own screen membrane. For adventure use, the sealed case is the better choice.
If you use the phone mostly on dry land, you may want only glass. Gorilla Cases sells the iPhone 8 Plus Screen Protector 3 Pack made of Japanese Asahi glass rated 9H. For privacy in public, the iPhone 8 Plus Privacy Screen 2 Pack uses a micro-louver filter.
Important: the waterproof case includes a built-in screen guard, so a separate protector is not needed or allowed with it. Choose one approach or the other.

Illustrative Scenario: The Beach Parent With a Classic iPhone
Imagine a customer who still loves an iPhone 8 Plus and takes it to the lake every summer. The phone gets sunscreen hands, sand, and a splash or two. This is an example, not a verified testimonial.
With the waterproof case on, the same customer films waist-deep boogie-board runs without worry. At the end of the day, the case rinses clean under a tap. The screen stays scratch-free behind the built-in membrane.
7 Protection Tips for Your iPhone 8 Plus Waterproof Case
- Inspect the gasket for hair, sand, or lint before every closure.
- Press all around the perimeter until the snap-lock clicks evenly.
- Test the sealed case without the phone first if you are unsure of the fit.
- Rinse the case with fresh water after salt or chlorine exposure and dry before opening.
- Do not install a separate screen protector under this case.
- Avoid exceeding 6.6 ft (2 m) or 30 minutes of submersion.
- Replace the case if the gasket cracks or the frame warps.
What Is in the Box and How to Install It
The box contains the iPhone 8 Plus waterproof case in black. Installation takes a few minutes the first time. Open the snap-lock, seat the phone, align the mute toggle, and close the halves evenly.
After installing, run your finger around the whole seam. Confirm Touch ID and touch response work through the membrane, and test the Lightning port cover. Always verify the seal before taking the phone near water.
Materials Explained: Polycarbonate and TPU
Polycarbonate is the impact-resistant plastic found in bike helmets and aircraft cockpit windows. On a phone this size, rigidity keeps the seal compressed evenly across the wide back. TPU is the flexible workhorse of running shoe soles and hockey puck rims.
In this case, TPU forms the gasket that seals the halves. The front membrane is optical-grade film that doubles as a permanent screen guard. Together they turn the biggest classic iPhone into a poolside camera rig.
