If you want to hit the beach — or the hot tub! — with your iPhone 6 Plus, a waterproof case is a must-have.

A waterproof case not only protects your iPhone 6 Plus from water damage, but from sand, dust, and dirt as well. It also lets you take awesome underwater pictures! Since failure isn't an option, it's so important to make sure you pick the right waterproof case for you. Here are the ones we recommend!

Have an iPhone 6 instead? No problem! Here are the best waterproof cases for iPhone 6!

1. Lifeproof Nuud

Best waterproof cases for iPhone 6 Plus: LifeProof Nuud

Waterproof without the screen protector

I love Lifeproof's Nuud line of cases because they don't implement the bulky screen guards many other waterproof options do. Instead, a vacuum seal system allows you to have full access to your screen while still providing excellent waterproof protection at up to 2 meters (6 feet) for up to 2 hours. You also get drop protection up to two meters.

2. Seidio OBEX

Ultra-slim waterproofing

The Seidio OBEX, which comes in a variety of colors, features a super-slim design that also makes it a great general purpose protective case when not in the water. The OBEX exceeds IP-68 ratings. That means it can withstand submersion of at least 1 meter (around 3 feet) for extended periods of time.

3. OverBoard

Waterproofing on a budget

If you want a waterproof case that only goes on when you go in, OverBoard is a great option. It functions more like a vacuum seal bag system but still gives you complete access to your iPhone 6 Plus. It's reusable, floats if you drop it in the water, and works at a depth of up to 6 meters (over 19 feet).

4. Catalyst

Best waterproof cases for iPhone 6 Plus: Catalyst

For deeper depths

Catalyst will protect your iPhone at depths of up to 5 meters (over 16 feet). It also provides complete protection against snow, dirt, and dust. The Catalyst comes in two different colors: black and white, and also supports most aftermarket Lightning cables so you don't have to take the case off to charge it.
