As a bewhiskered guy, you always have to be conscious of your looks.  Because the facial hair that you carry may not be suitable for every occasion.  Also, if you consider growing your facial long & dusky, that’s fine, unless you maintain it.  Otherwise, it might end up being unkempt.  Therefore, it is always advisable to regularly trim or shave it off to maintain the beard. 

The question that arises is if a beard trimmer is good for detail trimming?  The linked article can serve the basic purpose but imagine, you have an urgent meeting or a date, and you are running out of time, and not bathed as well.  The only thing that can save your time is the best waterproof beard trimmer that you can use under the shower.

You might feel that the only difference is water-resistant, but trust me, it works differently under wet conditions and on any beard length and texture.  This article is a curation of both types of shavers – one that can be rinsed off under running tap water and the other can be operated under the shower.  Moreover, we have also included factors to consider so that it would be easier for you to purchase the best trimmer.

Manli Haircut Kit (Cordless)

Manli’s 6 in 1 professional 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. 

Unlike other trimmers that have specific charging cable and adaptor, this trimmer is entirely different. It has a USB charging socket, which means you can connect to any computer, adaptor, or power bank. It is not only versatile in terms of functions but also in terms of charging.  Also, what mesmerizes and gains attention is its runtime – 2 hours runtime with 2 hours charging on cordless mode. It has a power button for easy use.

The upgrade doesn’t end here – the combs are also part of the improvement. The company has updated 4 length combs settings to 10 length guide combs.  The two combs cater to specific lengths – one guide comb can trim off from 6 to 12mm, and the other from 14 to 20mm.  The detachable tools are easy to clean and rinse off.

And these nifty tools work well with the already equipped self-sharpening stainless steel titanium blades that ensure even the detail cuts on the neck, sideburns, and cheek lines.  The company has not only considered build quality to match the requirement but also think about the skin safety of the users. There is no lubricant blade oil with the kit to smoothen the blades.

In my opinion, it is one of the best waterproof 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 hair trimmer into water. You just have to clean the blades to remove leftover hair.

  • Has USB Charging Socket
  • Waterproof and Noise-free
  • Different lengths of hair and comb settings
  • Washable attachments
  • Users complain about issues with sharpness of blades
  • Cheap price reflects build quality, but a good option for a limited burget

Factors to Consider While Purchasing Waterproof Hair & Mustache Trimmer

buyer's guide for waterproof beard trimmer


Price is crucial as well as an important pillar when it comes to buying a waterproof hair trimmer.  And anything that is cheap might not offer valuable results.  You always have to 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 that is sufficient to spend on grooming. According to our research, a good beard trimmer can cost less than 100 dollars. Now you might be thinking that 100 dollars are a big ask for some, but remember this is not like groceries that you buy every week. It is a long-term investment and you are going to use it for at least a few months or even years!


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.  This 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 and head hair.  Here, you need to be very picky about your selection. The above product reviews elaborate in detail about the beard length settings. Also, the blades need to be considered.  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, you would be expecting a product that lasts long and worth your investment when it comes to durability.  You might want a travel partner, on the go buddy, and any trimmer that doesn’t match up to your expectations would make you feel bad. Go through the above-listed products – they are the best group of products that either has durable blades or a durability kit. You will definitely get the desired one.

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 might exclude travel baggage capacity and you don’t want to suffer through all the hassles, So, it is always suggested that you look for a product that is lightweight and comes with a travel bag. A good point to note is that trimmers with vacuum features are generally bulky!


1. How frequently should I oil my hair clipper?

It is suggested that you should always oil your trimmer before the 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 blade 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. The above is the curated list of famous and branded waterproof beard trimmers you can choose from.

3. Is it safe to wash the entire trimmer?

Again, 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.


Waterproof beard trimmers come with more runtime, which is an advantage and is mostly usable under wet conditions.  Also, you can use it for several trims as compared to a normal trimmer that at most lasts for an hour. However, you should check the manual.  Besides, all the trimmers can be used on corded mode if the battery drains away.

Though the trimmers are designed for men, there are few that can cater to the entire family need. Check on it to diversify your usage.  For the salon lovers, it would be difficult to break the habit but trust me, once you start doing it at home, you will love it.

We would be glad to hear your trimming experience and tools that you use to keep yourself cool-looking and handsome.
