As someone who has spent years working in HVAC, I’ve seen firsthand how stubborn bathroom moisture can be. Even with good ventilation, steam and humidity build up fast.
If left unchecked, mold and mildew aren’t far behind, but a reliable bathroom dehumidifier can make a big difference.
In this guide, I’ll break down the best compact units that actually pull moisture from the air.
Top-rated bathroom dehumidifiers for true moisture removal
hOmeLabs HME1003
The hOmeLabs HME1003 is the most powerful unit on my list, and it’s the one I personally use in my own home.
hOmeLabs claims it’s rated for up to 7,000 square feet, which sounds impressive, but let’s be honest, 50 pints of daily moisture removal isn’t going to dry out an entire house. Still, in the room it’s placed, and even for nearby areas, this thing absolutely delivers.
I recommend it for larger bathrooms or spaces with heavy moisture buildup.
It includes a built-in pump for easy drainage and a 120 pint tank, so you won’t be dumping water daily. You can also set it up for continuous drain into a shower or tub, but the hose is sold separately.
Like the Midea Cube, this hOmeLabs model has WiFi controls, and while that might sound like overkill for an appliance like a dehumidifier, I’ve come to really appreciate the app reminders when it’s time to empty or clean it.
It produces about 55 decibels of noise, which is roughly the same as a standard bathroom fan. It's not silent, but totally reasonable.
It’s Energy Star certified, sits at 26" deep, and while it’s a bit bulky, the wheels and carrying handles make it easy to move where you need it.
If you’re dealing with high humidity and want something with a little more muscle than the Cube, this is your best bet.

Like the hOmeLabs model, the Midea Cube can remove up to 50 pints of moisture per day, making it more than capable of handling high humidity in larger bathrooms.
What sets it apart is its compact, nesting design. You can expand it for maximum dehumidification or nest it into a low-profile cube that sits more naturally on a shelf or countertop.
The Midea Cube is rated for up to 4,500 square feet, and although that may be a stretch in real-world conditions, it excels at localized moisture control.
I’ve installed this model in a few different spaces, and thanks to the built-in pump and included 16-foot drain hose, it handled vertical draining with zero fuss.
At just 48 decibels, it’s also one of the quietest units in this roundup, making it a great fit for homes where you don't want your dehumidifier to sound like a jet engine every time someone takes a shower.
Smart features are solid here, too: the WiFi-connected app is clean and responsive, and it integrates with Alexa for voice control.
Compared to the Shinco SDL-30P later on my list, the Midea Cube feels like a much more thought-out system for anyone already using smart home devices.
One thing to keep in mind with the Midea Cube is that the tank is smaller than the unit’s 50-pint daily capacity. If you’re not using the hose or pump, expect to empty it daily during high-humidity periods, or it will outpace you.
Honestly, I love how sleek and unobtrusive this one is. I’ve used it in a bathroom with limited floor space, and it fits right in without looking out of place.

If you’re after solid dehumidification without all the smart bells and whistles, the Waykar PD160B is a great, affordable pick.
It’s rated to remove up to 34 pints of moisture per day, which is impressive for a unit in this price range.
That said, the tank of this Waykar model only holds about 5.28 pints, so if it’s running full throttle, you’d need to empty it six or more times a day just to keep up (not ideal).
That’s why I strongly recommend using the included 6.5-foot drainage hose and setting up a gravity drain. It makes life way easier.
I’ve done this setup in a guest bathroom where a smart dehumidifier felt overkill, and once the hose was in place, it ran without needing daily attention.
Compared to the hOmeLabs or Midea Cube, this one is much more basic. There's no pump, no app, and only two fan speeds. Still, for many, that simplicity can be a plus.
It’s a great option for anyone who just wants to plug it in, set the humidity level, and walk away.
Even though it’s smaller in capacity, I appreciate the pop-up carry handle. It makes it easier to grab and move when needed. The build is simple, but it’s proven to be dependable for modest bathrooms or backup spaces.

If you’re looking for a dehumidifier that gets the job done without wrecking your wallet, the Shinco SDL-30P is often on sale for under $100, making it one of the most affordable picks on this list.
It can remove up to 30 pints of moisture per day, which is plenty for smaller bathrooms or laundry rooms.
Like the Waykar model, this unit doesn’t include a built-in pump, so I highly recommend using the included gravity drain hose.
Just note: the hose is less than two feet long, so depending on your bathroom setup, you might want to pick up a longer replacement to avoid creative drain pipe gymnastics.
One standout feature here is the activated carbon filter, which helps with odor control. It's a welcome bonus in any bathroom.
Just keep in mind, the filter needs to be replaced about every six months, and replacements run around $30 a pop. Still, for folks sensitive to musty or stale smells, it’s a worthwhile tradeoff.
I’ve used this one in a rarely-used half bath and honestly forgot it was even running. It’s compact, quiet, and just hums along in the background.
If you're not worried about smart features or advanced controls, it’s a solid little workhorse for everyday use.

Pros
Cons
The Pro Breeze PB-03-US is by far the smallest dehumidifier on my list, and with a moisture removal rate of just 3.1 pints per day, it’s also the least powerful.
Don’t let that fool you, though. This tiny unit makes a great countertop companion for bathrooms that don’t get overly wet, and it’s especially handy in RVs, campers, or small half baths.
I have one running at home and another tucked into my RV, and while it doesn’t pull gallons of water, it’s done a surprisingly good job of keeping condensation and humidity in check in those smaller, enclosed spaces.
It also has a slightly larger tank than the Shinco model I mentioned.
It's rated for up to 250 square feet, so while I’m often asked if it's good for closets or small pantries, I usually don’t recommend it for tight, enclosed spaces like that.
It does generate a small amount of warmth while running, and in tiny areas, that heat buildup outweighs the moisture removal. In those cases, I’d steer you toward a desiccant-style unit instead.
This model will automatically shut off when the tank is full, but there’s no gravity drain option, so unless you want it shutting off mid-day, it’s best to make emptying it part of your morning routine.
Compared to my top pick of the hOmeLabs 50 Pint, this is a low-profile, low-capacity unit that trades raw power for portability and ease.
It’s unobtrusive, ultra-quiet, and at around $70, it’s an affordable helper in smaller spaces. I’ve even packed one in a suitcase before; it’s that compact.

What to consider when purchasing a bathroom dehumidifier
Shopping for a bathroom dehumidifier isn’t the same as buying one for a basement or living room.
Bathrooms are small, wet, and often poorly ventilated, which means you need a unit that’s less about square footage claims and more about practical moisture control.

For bathrooms, don’t rely on “coverage area” specifications
Most dehumidifiers list a coverage area like 2,000 or even 7,000 square feet, but let’s be real, your bathroom is probably under 100. The problem? Bathrooms create a lot more moisture per square foot than the rest of your home.
A recent study showed that even a very short shower increases the humidity of your bathroom by about 20%, and if you don’t have some type of moisture control, this can really add up and create problems over time.
Instead of focusing on coverage area, pay attention to the moisture removal rate, usually listed in pints per day (PPD).
A small bathroom may only need 20–30 PPD, while larger or poorly ventilated spaces (like bathrooms without a window or fan) may benefit from something in the 50 PPD range, especially if nearby rooms also tend to get damp, such as in a basement apartment.
Pick the right drainage style for your bathroom setup
The biggest headache with bathroom dehumidifiers is often emptying the tank. You’ve got a few options here:
Pro tip: If you plan to run the unit 24/7, go with gravity or pump drainage to avoid constant babysitting.
Understand the Running Costs
Even small dehumidifiers draw power around the clock, and in humid climates or steamy bathrooms, they may need to run more often than you'd expect. That can add up over time, so it’s worth weighing a few things:
Pro tip: Check the unit’s wattage or hourly energy consumption (usually listed in kWh) to estimate monthly costs. Even small savings add up if it’s running every day.
Here’s an example of how dehumidifiers of different wattages stack up with the US national average kWh price of $0.17 per hour.
kWh price | Wattage | Price Per Day | Price Per Month (30 Days) | Price Per Year |
|---|---|---|---|---|
$0.17 | 100 | $0.136 | $4.08 | $48.96 |
$0.17 | 200 | $0.272 | $8.16 | $97.92 |
$0.17 | 300 | $0.408 | $12.24 | $146.88 |
$0.17 | 400 | $0.544 | $16.32 | $195.84 |
$0.17 | 500 | $0.68 | $20.40 | $244.80 |
$0.17 | 600 | $0.816 | $24.48 | $293.76 |
$0.17 | 700 | $0.952 | $28.56 | $342.73 |
