The convenience of trimming under the shower makes waterproof beard trimmers unique and distinctive from others.  Besides, using it with shaving cream is an advantage for sensitive skin guys. Lastly, the cleaning part of the trimmer post-shaving is a big relief to the users.

Here, the question arises, how will you be able to find the best waterproof beard trimmer?  Since the market is flooded with a plethora of trimmers, it will be a tough job for you to sort out the water-resistant trimmer for yourself.  And even if you find one, it would be only washable, which means you cannot use it under the shower; just rinse the attachments under the running water.

Considering the hassles of users and the requests we received from them in the last few months, we decided to write up an article. These trimmers are really good and work with any beard length.

According to us, this trimmer is the best one!

A trimmer that works on both modes, i.e., corded and cordless.

So, let’s start with the exclusive features.

Manli Haircut Kit (Cordless)

Expert Score

Best Feature: The beard trimmer caters to full body hair trimming by offering specific heads for each hairy part of your body.

Manli’s 6 in 1 professional hair clipper is an updated version of its original body.  There are tons of improvements from the original product.  And you’ll be quite amazed to read all the improvements. 

One being the versatility in terms of charging.  Yes, unlike other trimmers, this trimmer has a USB charging socket, which means you can connect to any computer, adaptor, or power bank. 

It will free you from the hassle of buying a cable or adaptor if it’s damaged.  Besides, it also relieves you from the struggle of finding a plug point for charging.

Adding this beard trimmer will not only save you from long-term ownership cost but also resolves the challenges that you face in day-to-day life for charging.

Another benefit that you may reap is the comb upgrade.  The company has updated trimmer guide combs.  Now the two combs cater to specific lengths – one guide comb can trim off from 6 to 12mm, while the other trims 14 to 20mm.  The detachable tools are easy to clean and rinse off.

Besides, the company also offers a sideburns trimmer with a trimmer comb that measures 3mm. It helps you trim sideburns and the backside of the head.

For the ones who experiment with different designs on their beards, Manli has brought a design trimmer with a comb.  The comb measures 3mm, which you are required to install on the trimmer and start designing.

Apart from this, buying this beard trimmer will give you the convenience of trimming body hair.

You get a 3-blades shaver head with this pack to shave underarm hairs and pubic area.  The two sides of the blade cut the hair, and the foil area (middle area) makes the skin smooth.  Besides, you also get a nose and ear hair trimmer attachment.

So this was all about the attachments.  Now let’s look at the blades and their material.

The beard trimmer features self-sharpening stainless steel blades that ensure detail cuts on the neck, sideburns, and cheek lines.  The self-sharpening blades are another deal-breaker as neither the blades will dull nor will you have to buy a new one.  

Also, there is no release button to detach the head, which may confuse you, but don’t worry, just place your hand on the head and push the blade away.

Lastly, the convenience of wet shaving satisfies our primary requirement.  All the attachments are washable, but we would still advise not to wash it every time and use the comb (included in the kit) to remove the stray hairs.  Though you can use it with shaving cream, it is still not ideal for trimming under the shower.  You may find a challenge fitting the limit comb as it requires hard-press.

All this is possible because the trimmer comes with a battery that offers 2-hours of runtime.  The battery takes 2-hours to fully charge, which is quite less than other trimmers on the list.

Lastly, we would say that if you hate attachments, you will not like this trimmer, but these attachments are the reason for their versatility.

  • USB Charging Socket
  • Completely Waterproof and Noise-free
  • Different lengths of hair and comb settings
  • Washable attachments
  • Users complain about issues with sharpness of blades
  • Inferior build quality
Verdict: In our opinion, it is one of the best beard trimmers for long beards because of its simplicity and the way it uses the current technology to improve. However, the body is not water-resistant, which means you do not have to put the trimmer into water. You just have to clean the blades and guards.

In addition, you get a Gillette ProGlide razor for the ones who prefer clean shave. It gives 100% results.  

Furthermore, the sharp blades are the reason behind all the wonders that you will be able to do on your mustache and beard.  The biggest benefit of this trimmer is that it has only one guard that does all the trimming jobs and doesn’t need a replacement, which means it is cost-efficient.  It is more innovative than all of Braun’s previous versions.

All this is possible because the beard trimmer offers an unparalleled 80 minutes runtime. However, it requires 8-hours of charging to deliver such performance.  What we like about this trimmer is it even operates when kept in charge.

The waterproof feature is an added advantage to the hair clipper.  Also, the beard trimmer is low-priced, which no other trimmers on the list are.

Panasonic ER-GB40-S (Cordless)

Expert Score

Best Feature: It can cut the thickest, densest, and most unruly hair.  Plus, it is easier to maintain as well.

Another product that caters to beard and mustache trimming is Panasonic ER-GB42-K, just like the above product.  However, it has only 19 precision length settings with an adjustment that ranges between 1-10mm.  The attached comb lifts and cuts the flat-lying hair on the skin.  The adjustable dial ensures customized trimming, sculpting, detailing, and cutting.  

And all this is achievable with precision 45-degree hypoallergenic blades that are durable and super sharp.  The blade prevents your skin from getting bruises, cuts, redness, or bumps.  

The trimmer becomes costly in the long run as the blades need replacement when it gets dull to retain the same performance.  Panasonic WER9606P is the blade that you need to purchase.

Talking about the control over the trimmer, it comes with an ergonomic and rubberized grip, which reduces the risk of falling or slipping from the hand.  

The trimmer offers 50 minutes of runtime with 15hours of charging, which is a major pitfall for this product. The trimmer features a Ni-MH battery.  It has a charging light indicator that shows a red light when in charge and stores the battery when not in use.

The trimmer for your facial hair is easy to wash and charge.  You can use it to trim off your subtle, stubble, short or long beard.  

Also, the trimmer for beard is compatible with both dry and wet hair cutting.  You can use a dry feature when plugged-in, and under the shower in cordless mode.  And it is easy to clean and wash as well. 

  • Highly recommended from TOMFW
  • 45 degree stainless steel blades for a perfect trim/li>
  • 19 precision settings
  • Wet and dry use
  • None- Just go for it
Verdict: Overall, it is the best beard trimmer cordless, waterproof, and finely built to cater to the requirements. Also, the hair trimmer has no attachment, which makes it quite convenient to carry and travel.

Philips Norelco Multigroom 7000 (Corded/Cordless)

Expert Score

Best Feature: The amazing feature about Philips Norelco Multi-groom 7000 beard trimmer is it offers unbelievable 5-hours runtime.  It is the only trimmer so far we have reviewed that has given this much runtime.

The trimmer is waterproof but not fully, which means you cannot use it under the shower.

The beard trimmer features Dualcut Technology, which includes dual blades that many beard trimmers fail to offer.  Besides, the blades are self-sharpening, which saves you from long-term replacement costs.

What we like about the blades is it doesn’t cause irritation nor does it cut your skin.

The set of attachments that it offers makes the trimmer the most versatile trimming tool.  It trims the nose, ear, pubic, underarms, beard, and mustache.  The company offers around 14-length guards, which is sufficient for a medium to a short beard.  However, the longer facial hair will still struggle with the attachments as they require more than 16mm guards.

Besides, there is a foil shaver attachment that caters to the nose and cheek line.  And it even saves you from buying a separate razor since the trimmer does clean up the edges effortlessly.

We believe that having such a beard trimmer means valuing your money and investing it in the right place.

The attachment beautifies the trimmer by bringing in more convenience to the user’s life.  And the build quality of the trimmer is super amazing.  The outer body contains stainless steel material.  Though it is heavier, it never makes the trimming session uncomfortable or painful.

Another feature that we would say is outstanding and fantastic is its battery life.  We mean which trimmer offers 5-hours of runtime in a single charge.  If we were at your place, we would have added it to our bathroom cabinet.

Tip: Charge this beard trimmer after every use to avoid the motor losing steam.  Also, it could lead it pulling, tugging, and uneven trims.

  • Zero long-run cost
  • Variety of guards
  • Head-to-toe trimming
  • Amazing runtime
  • Trimming under the shower not possible
  • Short of attachments for longer beards
  • Too many attachments
Verdict: The multi-purpose beard trimmer stands on its words in offering full body trimming. Though there are a few pitfalls, it won’t hamper the performance. In our opinion, it adds value to not only your shaving routine but also your bathroom cabinet.


Factors to Consider While Purchasing Waterproof Beard & Mustache Trimmer

waterproof trimmer


Price is crucial as well as an important pillar when it comes to buying a waterproof hair trimmer.  And anything cheap might not offer valuable results.  You should always have a good budget for buying such trimmers for beards that have so much to offer with so little to spend.  Here, a good budget doesn’t mean you need to break the bank, but a reasonable amount sufficient to spend on grooming.


A waterproof beard trimmer doesn’t mean that all the trimmers can work under the shower. Some might just require cleaning and rinsing off under the running water and while a few may operate under the shower as well.  It requires an in-depth analysis of selecting the best beard trimmers.

Trim Levels

The trim level plays an important role because you will use the trimmer kit for trimming or shaving off your beard or body hair.  Here, you need to be very picky about your selection. The above product reviews elaborate in detail about the length settings. Manufacturers prefer stainless steel blades, but not every time these blades work well.  You should also look for different blade quality and its features.


Durability is a must because you are investing your hard-earned money, and you would be expecting a product that lasts long and worth your investment when it comes to durability.  You might want a travel partner, the go buddy, and any trimmer that doesn’t match up to your expectations would make you feel bad. Go through the listed products; they are the best products that are durable and travel-friendly.

Size and weight 

Size and weight matter a lot as you not only confine it to your home, but you must be searching for something that you can carry anywhere.  Also, a product with heavyweight (like trimmers with vacuum functionality) might exclude travel baggage capacity, and you don’t want to suffer through all the hassles.  So, it is always suggestible to look for a lightweight product that comes with a travel bag.


1. How frequently should I oil my hair clipper?

It is advisable to always oil your trimmer before use for smoother and convenient trimming. And for oiling, you should hold the trimmer upside down – blade facing down. Switch on the trimmer and place 2-3 drops of oil on the top blade.

2. Which are the best waterproof beard trimmers?

The answer to this question depends on various factors to consider before investing your earned money into it. If you are finding the best waterproof beard trimmers, check the trimmer’s list in this article.

3. Is it safe to wash the entire trimmer?

You need to check the guide that comes with the trimmer kit or description. Some trimmers are washable and can be used under the shower, while some are limited to only rinsing off blades and guards.


So these are the waterproof beard trimmers, out of which, a few you can use under the shower, while a few of them work well with wet shaving.  Sorting out which one works for which purpose isn’t simple, which is why we undertook the responsibility of doing it.

We hope this article finds you well and you get the best waterproof beard trimmer for your beard.  Share your trimming experience with us, and let us know, which one is comfortable according to you.
