Why the iPhone 15 Plus Waterproof Case Is Essential for Beach Lovers and Adventure Parents
Picture your iPhone 15 Plus tumbling off the paddleboard into the shallows — and you scooping it up, wiping it off, and getting back to your playlist. The iPhone 15 Plus Waterproof Case from Gorilla Cases seals your 6.7-inch big-screen iPhone (2023) inside an IP68-certified, full-body enclosure rated for submersion to 6.6 ft / 2 m for a full hour. A built-in screen protector guards the front, a clear scratch-resistant back panel shows off the phone in HD clarity, and Qi and MagSafe wireless charging beam straight through the sealed shell. Built for beach vacationers, boaters, poolside parents, rainy-commute cyclists, and anyone who refuses to leave the big iPhone behind on big days out — this is the best iPhone 15 Plus waterproof case for full-seal protection without the brick feel. The Gorilla Family does not wait out the weather — and now your iPhone 15 Plus does not either.
Key Features
- Black frame with crystal-clear back: the transparent rear panel keeps your iPhone 15 Plus visible in HD clarity while the black trim stays understated.
- Premium materials: shock-absorbing TPU seals inside a hard polycarbonate shell with a scratch-resistant clear back panel.
- Case type: full-body, two-piece snap-on enclosure — front and back covers clamp together and seal the entire phone in seconds.
- IP68 waterproof certification: submersible to 6.6 ft / 2 m for up to 1 hour — pools, lakes, surf spray, and downpours covered.
- Re-sealable design: the gaskets keep a watertight seal through many open-and-close cycles, so you can remove the case and trust it again.
- Built-in screen protector: a touch-responsive front membrane shields the display — no separate protector needed, no bubbles.
- Shock and scratch protection: the sealed shell absorbs 6.6 ft / 2 m drops and locks out sand, dust, and grit completely.
- Charging compatibility: the back panel does not block the charging coil — Qi and MagSafe wireless charging work with the case on, though magnetic accessory grip is reduced through the shell.
- Slim sealed profile: under 0.5 in / 12 mm total thickness — genuinely pocketable for a full-seal case on a 6.7-inch phone.
- Compatibility: fits the Apple iPhone 15 Plus (2023, 6.7-inch) ONLY. It does NOT fit the iPhone 15, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 14 Plus, or iPhone 16 Plus.
Materials Explained — What Polycarbonate Shells and TPU Seals Actually Feel Like
The structural shell is polycarbonate — the rigid, shatter-resistant plastic used in bike helmets and aircraft cockpit windows. The two halves clamp around your iPhone 15 Plus with a satisfying snap, and the clear back stays optically sharp so the phone never disappears inside its armor.
The waterproofing lives in the TPU gasket system — the same flexible compound found in running shoe soles and hockey puck rims, molded here into precision seals around every seam, button, and the charging port door. Snap the halves together and the TPU compresses into a continuous IP68 water barrier.
The built-in screen membrane feels close to bare glass under your thumb — taps, swipes, and Face ID all behave normally, with just a whisper of softness reminding you it is taking the scratches for the team.
Altogether the case weighs about 2.4 oz (68 g) and keeps the phone under 12 mm thick — full-seal protection that still fits a jacket pocket.

|---|---|
| IP68 sealed enclosure | Survives 6.6 ft / 2 m underwater for 1 hour — dunks become anecdotes |

| Under 12 mm sealed profile | Full-body protection that still pockets like a normal big phone |
Step-by-Step Installation Guide
- Clean your iPhone 15 Plus with a microfiber cloth — a single grain of sand under a gasket can compromise the seal.
- Lay the phone face-down into the front half, aligning the screen with the built-in protector.
- Snap the back half on starting at the top, pressing around the full perimeter until every clip clicks.
- Inspect the seam line for an even, gap-free fit and confirm the charging port door is fully closed.
- Test the buttons, Face ID, and speakers — and before the first swim, run a 30-minute submersion test with a tissue inside instead of the phone.
Troubleshooting and Tips
- Audio sounds slightly muffled? A sealed speaker chamber trades a little loudness for waterproofing — raise the volume, and clarity returns fully out of the case.
- Touchscreen less responsive underwater? That is physics, not a defect — water confuses capacitive screens, so use the volume buttons as your camera shutter when submerged.
- Wireless charging not connecting? Center the phone on the coil — the sealed shell makes alignment matter a little more than naked-phone charging.
- Seal looking less snug after months of cycles? Inspect the gaskets for trapped sand or lint and wipe them clean; re-test in the sink before water outings.
- Cleaning after the beach? Rinse the closed case in fresh water, dry it, then open — never use alcohol wipes on the membrane or gaskets, which can degrade them.
FAQs
Which phones does this case fit?
It fits the Apple iPhone 15 Plus (2023, 6.7-inch display) only. It does NOT fit the iPhone 15, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 14 Plus, or any iPhone 16 model — the seal geometry is precise to the 15 Plus body.
What comes in the box?
The two-piece waterproof case (front and back covers) with the screen protector built into the front half.
How waterproof is it really?
IP68 certified — submersible to 6.6 ft / 2 m for up to 1 hour. Built for swimming, splashes, rain, and accidental dunks; not intended for high-pressure or prolonged deep diving.
Does it work with MagSafe and wireless charging?
Yes — the clear back panel does not block the charging coil, so Qi and MagSafe charging work with the case on. Magnetic accessory grip (wallets, mounts) is weaker through the shell, so test before trusting a mount at speed.
Can I take underwater photos?
Yes — the clear back and sealed camera window stay sharp underwater. Use the volume buttons as the shutter, since touchscreens cannot register through water.
What is the drop protection rating?
The sealed shell absorbs drops from 6.6 ft / 2 m onto hard surfaces, and it is fully dustproof and sandproof as a bonus.
Does Face ID still work?
Yes — the front membrane is optically clear over the sensor array, so Face ID works normally with the case sealed.
Are the buttons and ports accessible?
Yes — sealed button covers keep full clickability, and a gasketed door covers the USB-C port; open to charge by cable, click shut before water.
Do I need to add a screen protector?
No — it is built into the front cover. Adding another underneath will break the fit and the seal.
Is there a lanyard or strap option?
The case includes lanyard anchor points at the bottom corner — add any standard wrist strap for boats and pool decks.
Will the clear back yellow over time?
The polycarbonate panel resists yellowing far better than soft clear TPU. Rinse off sunscreen and skip alcohol cleaners to keep it crystal clear.
Is it bulky on the big 15 Plus?
No — under 0.5 in / 12 mm total and about 2.4 oz (68 g). It is among the slimmest full-seal cases we make, even on a 6.7-inch phone.
Is this a good gift?
For anyone whose summer includes water and an iPhone 15 Plus — it is the gift that prevents a four-figure mistake.
What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all iPhone 15 Plus cases. If the case doesn't fit your iPhone 15 Plus or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.
Can I open and close it repeatedly without losing the seal?
Yes — the gasket system is engineered to stay watertight through many open-close cycles. Keep the seals clean and re-test after sandy trips.

What Gorilla Family Customers Are Saying
★★★★★
Lake weekend, zero casualties
My 15 Plus went off the dock in about four feet of water while filming the kids. Pulled it up dry as a bone. The built-in protector feels nearly like bare glass and Face ID works through it without fuss.
— Melissa T., Minneapolis, MN
★★★★★
Surf trip approved
Two weeks on the Gold Coast — salt spray, sand, and one full dunk in a rockpool. Nothing got in. The clear back means my blue 15 Plus still looks like itself instead of hiding in a black box.
— Nathan W., Sydney, NSW, Australia
★★★★★
Wireless charging through the seal is the killer feature
I never open the case — it just sits on my MagSafe stand every night and charges through the shell. Survived a rainy bike commute season and one drop on wet pavement already.
— Imogen H., London, UK
★★★★★
Pool mom essential
Swim lessons twice a week and this case lives in the splash zone. Install took me under a minute, and after three months of opening and closing it still seals tight — I test it in the sink every few weeks.
— Dana R., San Antonio, TX
★★★★½
Great seal, slightly quieter speakers
Took it tubing all summer with zero leaks. Only nitpick: the sealed design muffles the speakers a touch, so podcasts need an extra volume bump outdoors. Fair trade for genuine waterproofing on a phone this size.
— Connor B., Vancouver, BC, Canada
