What to think about when buying a waterproof safe

As you have seen above, there are a lot of different safes in all kinds of shapes, forms, and designs. With that said, it can be difficult to know which safe you should choose. There are a number of things that need to be taken into consideration when making your choice in order to find the best safe for your needs.

Why buy a waterproof safe?

The primary reason to buy a waterproof safe is to add an additional level of protection for your valuables. Most items should not be in contact with water as it can completely destroy them. Especially if it comes to things like valuable documents, electronics, or firearms. With that said, having a waterproof safe can bring peace of mind knowing that your items are protected from water as well.

In addition, the vast majority of waterproof safes are also fireproof. The reason for this is quite simple:

On most occasions when safes are subject to water is actually not if there is, for example, leakage or flooding, but rather if there is a fire. The most common way to put out a fire is with water, and therefore, a fireproof safe also needs to be waterproof. This is great news, knowing that your safe is probably both fire and waterproof.

But whether there is flooding or a fire that is extinguished, a waterproof safe can be great to have.

Waterproof safe – Size and purpose

When considering the safe to buy, a great place to start is the size and purpose. Starting will purpose should be able to tell you the size as well.

If you are only going to store small objects such as passports and keys, you don’t necessarily need a huge safe, but rather can manage with a smaller safe box. At the same time, larger safes are generally more robust and resistant to break-ins, so this is something worth considering as well. Are you buying a safe solely for the purpose of being waterproof, or are you also buying it to prevent potential thieves from breaking in?

Also, think about where you plan to place the safe. How much room do you have for where you plan to store it? Naturally, a large safe requires more space and may not be ideal for all homes.

Then we also have the purpose. Different safes are designed with different interiors to store different items. A firearms safes course has different storage capabilities than those made for cash and jewelry. Therefore, think about the items you plan to store, and then choose a safe that meets your needs.

Furthermore, a lot of people buy a waterproof safety box because they want to be able to protect their belongings, for example, when going on a boat. In this situation, a safety box that you can carry with you may be the most suitable option. Whilst keeping your items locked and safe, it will also protect your belongings from water.

Electronic or mechanical  waterproof safe?

There are both electronic and mechanical safes on the market. This means that you either use a key to open or open with a pin code, or in some cases, your fingerprint.

The great news is that many safes are now equipped with box a digital and a mechanical lock so you can choose, or use a key when it has run out of battery or when you have forgotten the code.

Safes that combine electronic and mechanical tend to be quite popular as they offer a greater alternative for opening.


Last but not least, different safes have different performances when it comes to water. Some safes are only ” splashproof” and can handle water for shorter periods of time, but others can withstand deep water for hours. This is something that is important to take into consideration depending on where you plan to place it and how big the potential risk of water is

When do you need a waterproof safe?

There are many good reasons why you would want a waterproof safe. I would say that you need a waterproof safe all the time, but there are some situations when it is more important. One such occasion is when you are storing items that are particularly sensitive to water. Some items can handle water better than others and so in some instances, it won’t be as important.

Another time when a water-resistant safe is important is when you are storing the safe in places where there is a great risk, or at least potential risk, that it may be subject to water. This brings us to the next point.

Where will you store your waterproof safe?

Where you will store your safe obviously has a great effect on how important it really is to have a waterproof safe. Some of the places where the risk of it being subject to water are:

  • Places where flooding can occur
  • Places where sprinklers are installed
  • When stored in a boat
  • When stored in other places where water is common

Waterproof rating

As you have seen above, different safes have different water-resistant ratings. Therefore, it is important to think about your water-resistant needs when buying a safe. Some can be fully submerged for a couple of hours, others are just able to withstand water splashes or low levels of water.  In many instances, the greatest risk is a sprinkler system and perhaps high-powered hoses from the fire department in the case of a fire, and in these situations, you won’t have to look for a safe that can be fully submerged.

Therefore, think about the potential risks that the safe will be subject to and then choose a safe accordingly.

Are safes waterproof?

In general, safes are not waterproof. Most of the safes on the market are not waterproof and therefore, it is important to actively look for those that are if this is an important criteria for you.

At the same time, nothing is ever completely waterproof, so technically, water resistance would be the best terminology to use. Any safe, waterproof or not, will eventually start to leak. This is why it is important to take appropriate actions shall your safe ever be subject to water.
