A quality waterproof phone case for a cruise costs $10–$50, with dry bags starting at $10 and premium hard-shell cases hitting $40–$50. You don't need to buy one onboard — ship prices are marked up 2–3x — so grab one before you sail.

You packed sunscreen, your passport, and your excitement. What you probably forgot is something to keep your $1,000 smartphone from becoming an expensive paperweight the moment a wave slaps the pool deck. Waterproof phone protection is one of the smartest, cheapest things you can buy before a cruise — and one of the most overpriced things you'll regret buying onboard.
How Much Do Waterproof Phone Cases Actually Cost?
The price range is wide, but the sweet spot for cruise use is $15–$30. Here's what you're actually getting at each tier:
| Option | Price Range | Best For | Waterproof Rating |
|---|---|---|---|
| Universal dry bag pouch (no-brand) | $10–$15 | Beach days, snorkeling, pool | IPX8 (submerge to 100ft) |
| Universal dry bag pouch (brand name, e.g. JOTO) | $12–$18 | Same as above, more reliable seal | IPX8 |
| Hard-shell waterproof case (phone-specific, e.g. Lifeproof FRĒ) | $40–$80 | Active excursions, kayaking, SCUBA | IP68 |
| Floating waterproof case with wrist strap | $15–$25 | Pool, water parks, island beaches | IPX8 |
| Onboard gift shop equivalent | $25–$45 | Desperation only | Varies |
| Cruise excursion rental (snorkel tours) | $5–$10/day | Single-use emergencies | Varies |
The onboard gift shop markup is brutal. A dry bag that costs $12 on Amazon will run $30–$40 in the ship's boutique. Budget travelers: buy ahead.

What Drives the Price (and What Actually Matters)
Phone size and model specificity is the biggest cost driver. Universal dry bags fit any phone and cost a fraction of model-specific hard cases. The tradeoff: touchscreens don't always work through the plastic film of a dry bag.
IP rating matters more than brand name. Look for:
- IPX7: Submersion up to 1 meter for 30 minutes — fine for pool splashing
- IPX8: Submersion beyond 1 meter — what you want for snorkeling or serious water activities
- IP68: Full dust and water protection — hard-shell cases only, ideal for active shore excursions
Wrist strap or lanyard is worth the extra $2–$3. Dropping your phone overboard or into a cenote is a much bigger problem than the case cost.
Touch sensitivity is a real issue with cheap dry bags. If you need to take photos underwater, spend $20+ on a bag with an optical-clear lens panel and tested touch response. The $10 no-brand bags often fog up or kill touchscreen response within a day.
Your itinerary drives the right choice. Caribbean beaches and pool decks? A $12–$18 dry bag is all you need. Alaskan kayaking excursion or Cozumel cenote dive? Spend $40–$80 on a hard-shell case rated for serious submersion.

Practical Tips to Save Money and Not Wreck Your Phone
Buy before you board — every time. This isn't optional advice. Ship gift shops sell waterproof pouches for 2–3x retail. Amazon, Walmart, and Target all carry solid options. Order the week before you sail.
The JOTO universal dry bag is the gold standard budget option at $12–$15. It's been the top-selling cruise-prep item on Amazon for years for good reason: it works, it floats, and it comes with a neck strap.
Don't rely on your phone's built-in water resistance. Apple's IP68 rating sounds impressive until you read the fine print — it's tested in lab conditions with still freshwater, not chlorinated pool water or saltwater. Both will degrade seals over time and void your warranty. Always use a case in the ocean or pool.
Test it before you use it in the wild. Fill your sink, pop your phone in the case (without the phone first), submerge it for 5 minutes, and check for moisture. A $15 bag that leaks in your bathroom sink would have cost you a phone.
For excursion-heavy itineraries, budget $40–$60 for a Lifeproof or Catalyst hard case. If you're doing kayaking in Alaska, waterfall hikes in Dominica, or snorkeling in Turks and Caicos, a dry bag won't cut it. A hard-shell IP68 case lets you shoot photos underwater and actually use your phone.
Pack two. Seriously. A $12 dry bag as a backup takes up zero space and weighs nothing. If your primary case fails or you lose it on a beach excursion, you have a fallback.
Recommended Picks by Cruise Type
| Cruise Type | Recommended Option | Typical Cost |
|---|---|---|
| Caribbean beach/pool-heavy | JOTO universal dry bag | $12–$15 |
| Bahamas/Mexico all-inclusive resort day | Floating dry bag with wrist strap | $15–$22 |
| Alaska active shore excursions | Lifeproof FRĒ (phone-specific) | $50–$80 |
| Mediterranean sightseeing | Basic splash-proof sleeve | $10–$15 |
| Adventure (cenotes, snorkeling, kayaking) | Catalyst or Lifeproof hard case | $40–$75 |
| Budget cruiser, any itinerary | JOTO 2-pack | $15–$18 |
One more thing: cruise ship photos taken through the ship's own photographers cost $20–$35 per print or $200+ for a package. A waterproof case that lets you shoot your own underwater photos on excursions pays for itself on day one.
