The best Samsung Galaxy S25 Plus waterproof case in 2026 is the Gorilla Cases Galaxy S25 Plus Heavy Duty Screen Protector Case, a fully sealed IP68 shell rated to 6.6 feet (2 meters) of fresh water for 30 minutes, with a 2.0mm raised camera lip and a laminated front screen guard. Unlike a rugged case, it uses a continuous silicone gasket around the entire perimeter, so water has no entry path at the seam. That gasket is the whole difference between splash resistance and true waterproofing.
Gorilla Cases builds this shell for the 6.7 inch Galaxy S25 Plus specifically, because a gasket only seals when the tolerances match one device. The Gorilla Family should never buy a universal waterproof pouch and expect this level of sealing.
Why a Galaxy S25 Plus Waterproof Case Matters in 2026
The Galaxy S25 Plus already carries an IP68 rating from Samsung, so the obvious question is why a case adds anything. The answer is that Samsung IP68 covers a factory-fresh phone in fresh water, and it degrades.
Adhesive seals around the display and the SIM tray lose compression over time. Samsung explicitly excludes water damage from the standard warranty, and the port seals on a two-year-old phone are not what they were on day one.
A dedicated waterproof case restores that margin with a fresh, replaceable gasket. It also seals the USB-C port and the speaker grilles, which are exactly the openings a bare IP68 phone relies on internal membranes to protect.
There is a salt and chlorine problem too. Samsung IP68 is certified in fresh water only, so pool and ocean exposure sits outside the rating entirely. A Samsung Galaxy S25 Plus waterproof case is the only way to take the phone into either with confidence.
10 Key Features of the Best Galaxy S25 Plus Waterproof Case 2026
- IP68 sealed construction rated to 6.6 feet (2 meters) of fresh water for 30 minutes.
- Continuous silicone perimeter gasket compressed by a two-piece snap frame with no interruption at the corners.
- Laminated front screen guard that keeps full touch sensitivity on the 6.7 inch panel while sealing the display.
- 2.0mm raised camera lip with an optically clear window over the 50MP wide and 10MP telephoto lenses.
- Sealed USB-C port plug with a captive tether so it cannot be lost.
- Acoustic membrane over the speaker and microphone that passes sound while blocking liquid.
- 13 foot (4 meter) drop rating, because the same rigid frame that seals also absorbs shock.
- Polycarbonate frame with a TPU sealing collar, the combination that holds compression without cracking.
- Lanyard attachment point at the corner for kayaking, boating, and dock work.
- Wireless charging pass-through at 15W so the case stays on between uses.
The acoustic membrane is the part cheap sealed cases get wrong. Without one, either the sound is muffled to uselessness or the seal is not actually continuous.
Who the Galaxy S25 Plus Waterproof Case Is For
Swimmers, anglers, kayakers, boaters, pool parents, and anyone working in rain or washdown environments. It is also the right answer for snorkelers who want photos without a dedicated action camera.
If you need armor rather than sealing, the Galaxy S25 Plus 3-Layer Shockproof Protection Cover gives higher impact resistance at a lower price. For everyday drop protection without the gasket, the Galaxy S25 Plus Military Grade Drop Proof Cover is the practical daily pick.
Anyone who wants the phone finish visible should look at the Galaxy S25 Plus TPU Clear Cover Case, though it offers no water sealing at all. The complete range is in the Galaxy S25 Plus Cases collection.

An Illustrative Use Scenario
Here is an illustrative example of how this plays out. Picture a charter fishing guide on Lake Erie who needs the Galaxy S25 Plus for navigation, weather radar, and customer photos.
The phone is exposed to spray for eight hours straight, and spray is worse than immersion because it never stops. Bare IP68 handles a single dunk far better than it handles constant salt-adjacent mist and wind-driven rain.
With the sealed shell on, the USB-C plug stays closed, the acoustic membrane keeps calls audible, and the lanyard point means a fumble goes into the case rather than into the lake. The 13 foot drop rating covers a fall from a flying bridge to the deck.
At the end of the day the case gets rinsed with fresh water and the phone never touches it. This scenario is illustrative and is not a customer testimonial.
Protection Tips for Your Galaxy S25 Plus Waterproof Case
- Water test the empty case first. Seal it with a folded paper towel inside and submerge it for ten minutes before ever trusting it with the phone.
- Inspect the gasket every single time. One hair or one grain of sand across the silicone defeats the entire IP68 seal.
- Rinse with fresh water after salt or chlorine. Both degrade silicone over months of exposure.
- Do not exceed 6.6 feet of depth. IP68 at 2 meters is a pressure rating, and deeper water will force the gasket.
- Avoid hot tubs and hot showers. Steam penetrates seals that liquid water cannot, and heat softens the gasket.
- Replace the gasket annually if the case is used in water more than a few times a month.
- Keep the USB-C plug closed whenever it is not charging. The plug is the most common point of user error.
- Dry the case fully before opening it. Water sitting in the seam will run onto the phone the moment you unclip the frame.
What Is in the Box Plus Installation Steps
The Gorilla Cases Galaxy S25 Plus waterproof case ships as a sealed front and back assembly with the gasket pre-fitted, plus a spare USB-C plug, a lanyard cord, and a microfiber cloth. A fitment card confirms the SM-S936 model match.
Installation takes about three minutes and should not be rushed:
- Step 1. Water test the empty case for ten minutes and confirm the paper towel inside is dry.
- Step 2. Power the Galaxy S25 Plus off and clean the display and back glass completely.
- Step 3. Unclip the frame and inspect the full silicone gasket under good light for hair, lint, or grit.
- Step 4. Seat the phone face-up into the back shell with the camera cutout aligned to the vertical lens array.
- Step 5. Lower the front frame on evenly rather than starting at one corner.
- Step 6. Press along all four edges until every clip has audibly latched.
- Step 7. Insert the USB-C plug fully and confirm it sits flush.
- Step 8. Power the phone on, test the touchscreen edges, the speaker, and the microphone before any water use.

Galaxy S25 Plus Waterproof Case FAQs
1. What does IP68 mean on a phone case?
IP6 means fully dust tight and the 8 means protected against continuous immersion, here defined as 6.6 feet of fresh water for 30 minutes.
2. My Galaxy S25 Plus is already IP68. Why add a case?
Because factory seals degrade, water damage is excluded from the warranty, and Samsung IP68 is fresh water only. A case gives you a fresh, replaceable gasket and covers pool and salt exposure.
3. Can I take it in the ocean?
Yes, within 6.6 feet of depth. Rinse the case with fresh water immediately afterward.
4. Can I take photos underwater?
Yes, through the optical camera window. Touch response underwater is limited, so set up the shot before you submerge and use the volume key as the shutter.
5. Does the case muffle calls?
The acoustic membrane passes speech clearly. Expect a modest reduction in maximum speakerphone volume.
6. What is the drop rating?
13 feet, or 4 meters, onto concrete.
7. Does it fit the Galaxy S25 or S25 Ultra?
No. This is the 6.7 inch S25 Plus, model SM-S936. Gasket cases are strictly model specific.
8. Can I leave it on all the time?
Yes. It supports 15W wireless charging, so the case can stay on between water sessions.
9. How thick is it?
About 5.0mm per side and roughly 104 grams.
10. Is it safe in a hot tub?
No. Heat and steam are outside the IP68 test conditions and will compromise the gasket.
11. How often should the gasket be replaced?
Annually with frequent water use, or any time you see a nick, flat spot, or discoloration.
12. Does it work with face unlock?
Yes on land. Underwater the front camera view is distorted, so use the PIN.
13. How tall is the camera lip?
2.0mm, with an optically clear window rather than an open cutout.
14. What is the return policy?
Gorilla Cases offers a 30-day exchange policy on every order.
