Waterproof case and Zagg glass shield

I recently upgraded to an iphone 6s plus. I put a ZAGG invisible shield glass. I like Lifeproof but on their site it states....Our cases are precision-fit to the device. Any other products that change the dimensions of the device are not compatible with our cases.

I NEED a waterproof case....for my peace of mind. We will be going to Florida this summer and I like to take pictures at the beach. Any idea what waterproof case will work with my invisibleshield?
