Best Waterproof Beard Trimmers [2021] – Perfect Wet Trim

A man looking for the best waterproof beard trimmers on the market is usually looking to solve one of two issues. These are the need to use the trimmer in the shower (or just to trim wet), and the need to be able to clean the trimmer easily. 

There are so many beard trimmers on the market right now it can be difficult to know which ones you can rinse off without the fear of damaging it.

What I’ve done is ranked the best waterproof ones out there right now taking several important factors into consideration. 

If you’re in a rush, the Philips Norelco MG7750/49 (Amazon Link) is our best waterproof beard trimmer of 2020.

Factors To Consider When Buying A Waterproof Beard Trimmer

1. Do you need it to be cordless?

If you’re looking to use this trimmer in the shower, a cord wouldn’t be very practical. It’s unlikely that you’ve got a socket within reasonable reach of the shower. 

A cordless trimmer would be much less restrictive in these circumstances. Having said this, corded trimmers do give you that extra little bit of power. 

Consider where you’ll be trimming before you’ll be using it when making your decision.

To summarize, if you go for a corded trimmer, just be sure to check the cord length before committing. If you’re going for a cordless trimmer, make sure the runtime on full charge is adequate as well. 

2. What is the trimmer made of? 

I’m talking about the frame, the guards and the blades. Titanium and stainless steel are built for the long run, of course. Most high quality (yet affordable) beard trimmers opt for these in some way or form. 

A rubberized ergonomic grip feels exceptionally comfortable (I love it). But, if you leave it damp it does allow for a build-up of scum in the ridges. Just something to make a note of.

The moral of the story would be to gently towel-dry your trimmer after you use it wet. 

Don’t leave it wet, but at the same time, don’t be too rough when you dry it down after you use it.

Ultimately, go for durability. Buy a good beard trimmer that will last, instead of having to replace it time and time again. 

3. What beard length are you working with?

I’d recommend that men with long beards do get a waterproof trimmer. It’s all the more important that you’re able to rinse those long strands from the crevasses under the blades.

Let them build up and they can devastate a trimmer. 

But either way, when choosing a trimmer, it’s important to ensure that you’re happy with the length guards they come with before buying it. 

A nightmare situation would be buying a trimmer without checking first, and realizing that the length guards it’s come with are too short for the beard you want to maintain. 

If you also want a more nuanced and intricate style, you may want a wide range of length guards available in smaller increments. This is so you can vary the length in different areas of your beard if you want to. 

4. Will you be using it only on your beard?

If you intend to use it on different hairy parts of your body, try to ensure that the trimmer allows for this. 

Certain trimmers have several attachments that provide the ability to trim anywhere you can think of.

These are incredibly practical for some men, but others do prefer to have a trimmer solely dedicated to their beard. 

If you do intend on using the trimmer on multiple areas of your body, I’d say it was even more important for it to be waterproof.

The Best Waterproof Beard Trimmers [2020]

1. Philips Norelco Multigroom Series 7000, MG7750/49

Best features

It really is a great device at this price point, offering exceptional value for money. 

Here’s the Amazon Link.

Although it isn’t suitable for use in the shower, the trimmer is waterproof. This enables you to clean it under cold water as and when you please. But that’s just the start of it. 

DualCut technology blades are a dream, with twice the number of blades and self-sharpening technology.

They glide across the skin effortlessly leaving minimal irritation and a very slick and even cut. 

What I love about this trimmer is the versatility. It stays true to its name by enabling you to trim your beard, heard, ears, nose, chest and pubic region with its wide range of attachments.

The foil shaver attachment is a bonus, allowing you to effortlessly shave under the neckline and above the cheek line. 

Not having to use a separate razor or shaver to clean up the edges, define the borders and get rid of stubble is a huge practical benefit.

Buying an all-in-one trimmer such as this does bring efficiency to a grooming regimen.

The precision trimmer attachment is great for the final touches. There’s nothing more attractive than sharpening up the edges.

This could be your neckline, cheek line or around the mustache. 

It’s also very durable, with the frame being built from stainless steel that never feels uncomfortable against the palm. This is the case even with the longer trimming sessions. 

The battery life is also noteworthy, clocking in at 5 hours runtime when fully charged. Its Lithium-ion battery does it’s duty here.

This is more than enough time for many uses.

However, get into the habit of charging it after each use to prevent the motor from losing steam mid-trim after a while. This can lead to tugging, pulling, and uneven trims.

What you may not like

Although it’s easily rinsed, the trimmer isn’t suitable for shower use – this may be an issue for some.

Hardly a deal-breaker, but it’s important that you know what length guards it comes with. The Multigroom comes with 14 length guards ranging from 1mm to 16mm.

Although this is more than enough for most bearded men, there are of course those long-bearded warriors for whom it wouldn’t be enough. 

Also, if you aren’t a fan of keeping hold of multiple different attachments, this may not be for you. Its key feature is versatility thanks to its numerous attachments, but storing all of them may not be for you. 


The Multigroom does exactly what it claims to do. This waterproof trimmer was built to be the go-to “all-in-one” trimmer, and that’s exactly what it’s become. 

2. Remington MB4700

An ultra-modern, fully washable, and cordless “smart trimmer” with all the frills.

Here’s the Amazon Link.

First off, it’s important to note that unlike a few of the others in this list, this is a beard trimmer. It doesn’t pretend to be anything else. But what sets this trimmer apart is the modern convenience it brings to the table. 

Because it replaces the need for a bunch of length guards with a fully motorized comb, it immediately reduces storage requirements.

The comb moves in 0.1mm increments, which means that you’re capable of achieving 175 length settings between 0.4mm and 18mm. That’s right folks, it can deal with stubble beards as well. 

Some may say this is excessive, but surely you can appreciate the sheer number of options available? You can make very intricate changes to a beard with such a vast number of length options. 

The in-built memory can store previous length settings, which means you don’t have to set it every time you want to uses it. Again, it saves time and adds convenience.

When this is paired with the “wake up” feature, the sky is the limit. What this refers to is the ability to just pick up the trimmer and have it automatically turn on to your favorite length setting. I mean, it’s like something straight out of Iron Man, right?

If this isn’t “smart” enough yet, the Remington MB4700, much like the Braun MGK5080, has an auto-sensory motor.

In other words, it’s able to adjust the blade speed according to the thickness of the beard hair. This leads to an incredibly personalized trimming experience. 

It’s able to speed up when it needs to and slow down when it can. Overall, this aims to reduce tugging, pulling and irritation.

Top this all off with a digital touch screen and you’ve got a very competent, and fun-to-use beard trimmer on your hands. 

What you may not like

Some users feel as though this trimmer prioritizes features over actual trimming capability. But most people do feel as though it provides a very clean, neat, and even cut. 

The runtime on a full charge isn’t as impressive as a couple of others on this list, but it’s still perfectly adequate. Once again, when you’ve got a habit of charging your device after each use this doesn’t even matter.

It states that you’d be able to get 50 minutes out of it, but you’d probably be able to squeeze out around 1hr 15 minutes if you really wanted to. 


As a fan of convenience and modern touches, this beard trimmer does impress me. Remington appears to be pushing the boundaries in terms of what a trimmer is expected to do. 

Eventually, I think these features will become commonplace. It’s a strong contender for the number one spot on this list of best waterproof beard trimmers.

However, the Philips Norelco Multigroom wins the top spot by a small margin because of the versatility it adds at an even better price point. 

3. Braun All-in-One Trimmer MGK5280

Best Features

Another multi-purpose trimmer allowing you to trim your beard, head, nose, ears, and body. Fully wash-proof, you’ll be able to rinse it and shower with it without any problem at all. 

Here’s the Amazon Link.

So you may be sick of hearing about the beauty of multi-purpose trimmers by now. What sets the MGK5080 apart from the rest of the pack? 

It also has an autosensing motor, for one. It automatically adjusts blade speed according to the thickness of the hair you’re cutting.

This immediately reduces the risk of pulling and tugging when attempting to tackle the denser parts of a beard (or other regions). 

Its battery life is also impressive, but not as impressive as the top two choices. It clocks in at 100 minutes of a full charge, with a quick charge option available in 5 minutes. 

What I also like about this trimmer is that it is capable of trimming 13 different lengths between 0.5mm and 21mm with only 4 combs.

This is thanks to two of them being adjustable, significantly cutting down on the number of combs you’ll need to store. 

Although the thought of having many different combs might seem productive, ultimately, they can be a struggle to store.

Asides from the 4 combs, the trimmer comes with a body groomer attachment, an ear & nose trimmer attachment and a detail trimmer attachment.

The dual-purpose combs can be adjusted to the point where the device actually becomes a pretty competent hair clipper as well if you want it to.

Much like the two trimmers ranked above, the attachments enable you to sculpt a very meticulous beard while not neglecting other hairy regions.

They cut very smoothly and evenly, and neatness is specifically mentioned by many users. 

I’ll finish with a nice little touch. The travel lock ensures that the trimmer doesn’t turn on in your bag without your consent. There’s not much worse than a trimmer that drains its own battery, even before you get to your destination!

Traveling with this trimmer is made so much simpler as a result, with a lightweight design and a soft travel bag making it even more practical in this respect. 

What you may not like

The pictures can be misleading, as this trimmer doesn’t actually come with a foil shaver attachment. Some reviewers do mention being irritated by this, although it doesn’t mention this attachment anywhere in the description. 

A minor issue is that the blade can heat up a little after a particularly long trimming session, more so than with others. 


It’s probably the simplest of the three to use and cuts down significantly on storage space due to its adjustable combs. However, it doesn’t quite match the top choices in terms of cutting ability or durability. 

Final words

Looking for a good waterproof beard trimmer isn’t as simple as it may first seem. There are plenty of trimmers that claim to be washable but actually aren’t. There also trimmers that are perfectly washable but are of a low standard in other respects. 

Hopefully, this article has condensed a lot of the research you would otherwise have had to do yourself. If you have any questions or comments, be sure to leave them down below! Are there any other trimmers you feel should have made this list?
