Since bathrooms are small, damp spaces, they're particularly prone to the mold and mildew that can grow in moist areas. Luckily, a dehumidifier is a simple solution that'll remove dampness from your bathroom quickly and effectively. The very best dehumidifiers for bathrooms are compact enough to fit in any-sized powder room, and run continuously to remove a good amount of the humidity from the air before anything starts, for lack of a better word, growing.
What To Look For In A Bathroom Dehumidifier
Now, by design, all dehumidifiers pull moisture from the air to prevent that musty scent and mold buildup. But when you're searching for a dehumidifier to put in your bathroom, you'll definitely want a high-efficiency model. High-efficiency dehumidifiers can accomplish a lot of what an extra-large dehumidifier can, but without taking up much space. Be on the lookout for a dehumidifier that can pull at least 9 ounces of water from the air per day, and a tank capacity larger than that, so you can go a few days before having to empty it. That way, it's a low-maintenance solution you don't have to put much energy into.
You also want to consider your living situation before you go all-in on a great bathroom dehumidifier. For example, if your bathroom is right next to your bedroom, the last thing you want is a super loud, clunky unit that keeps you awake all night. Or if you're prone to allergies or have asthma, it's really important to invest in a dehumidifier with a HEPA filtration system to truly clear the air.
So whether you need a dehumidifier for bathroom mold or simply want to curb excess moisture, check out the highly rated bathroom dehumidifiers below.

The Best For Allergies & Mold Sensitivity: Tenergy Sorbi Air Dehumidifier
- Also available on Walmart, $90
- Dimensions: 8.5 x 7.7 x 12.4 inches
Not only does this sleek dehumidifier make your air more comfortable, but it also doubles as an air purifier.. This unit features a 1-liter capacity tank and can remove up to a whopping 35 ounces of moisture from your bathroom per day. It also comes with a HEPA filtration system, which is the best of the best when it comes to removing every last allergy-causing particle from the air, so you can breathe easy while you get ready for the day. Plus, this dehumidifier runs super quiet (35 to 42 decibels, depending on which setting you've chosen) and features an auto shut-off function. This dehumidifier is a bit heavier, at nearly 7 pounds, but its dimensions are comparable to the overall best pick above.
According to one reviewer: "Our bathroom does not have any ventilation and has been having surface mold. I got this one to filter the air when we are not in the shower And run the dehumidifier during showers. It has been working well and the fan is pretty quiet. When the fan is on high it's a little loud for me but on low it is just right. My towels are not damp the next day anymore so it must be working. I also feel like my bathroom is less smelly.”

The Best Small Dehumidifier For Bathrooms: Eva-Dry Renewable Dehumidifier
- Also available on Ace, $20
- Dimensions: 5.5 x 2.5 x 5.5 inches
Although it offers less power than the other options on the list, the Eva-Dry dehumidifier is a wallet-conscious pick that takes up next-to-no space in a bathroom — and it’s still earned a 4.3-star overall rating after more than 28,000 reviews. The technology of this option is very simple and operates without the use of electricity or batteries. Instead, it’s filled with orange silica gel beads that absorb 6 ounces of moisture from the air. Once it’s hit capacity, the unit can be plugged into any electrical outlet, where the heat generated will release the water vapor, and return the dehumidifier to baseline.
Weighing just 1.2 pounds, it’s the lightest and most compact option on the list, and won’t need to be placed near an outlet, except when it needs to be reactivated. That being said, if you’re dealing with a lot of humidity, you’ll likely have to plug it in fairly often to reactivate the silica beads, so this won’t be the best choice for heavy humidity or larger bathrooms.
According to one reviewer: “We just moved a home built in 1954. It’s very original including little to no ventilation including in the bathroom. I hung this in our bathroom and it has helped tremendously to take moisture from the air. It turned dark green about 3 weeks after using. I plugged it in for a day and it dried out and turned back to orange. Very cool device!”

The Best For A Large Bathroom: Ivation 13-Pint Small-Area Dehumidifier
- Also available on Home Depot, $203
- Dimensions: 10.6 x 6.9 x 17.5 inches
Although this high-efficiency dehumidifier is a bit taller and heavier than other small-space units (nearly 18 inches in height and 14 pounds in weight), tons of reviewers insist it's worth the investment. That's because it's nearly as slim as smaller models, making it easy to slide it right beside your tub or bathroom cabinets and never notice it's there. And, impressively, this dehumidifier can collect nearly 12 pints of water a day (that's 188 ounces).
This model also runs without a compressor, so it's one of the quieter dehumidifiers out there. (The decibel rating isn't listed, but many reviewers confirm it operates quietly.) It also features multiple ways to drain the 13-pint (or 208-ounce) tank. You can do it manually every couple of days, or you can release the stopper and allow the tank to drain continuously into a sink or drainage hole. This unit even features an easy-touch LCD screen and an automatic shut-off to prevent any overflow.
According to one reviewer: "This is my favorite Amazon purchase of the year. Our 2008 Rockwood Roo travel trailer [...is] housed near the Chesapeake Bay, so moisture is a constant, year-round. We only visit the trailer on occasion - it's not used for full-time living. The dampness had caused a terrible musty odor that I could not eradicate by cleaning. I bought this dehumidifier and placed it in the bathroom shower pan. Hooked up the electric, and attached the included clear hose (draining to the grey water tank (left partially ajar outside to drip) for full-time use. I could not believe how well this worked!”

A Solid Budget Option: Pohl Schmitt Electric Dehumidifier
- Also available on Walmart, $25
- Dimensions: 6.1 x 5.1 x 8.7 inches
Perfect as a small bathroom dehumidifier, this option has all the features you need for half the price of some of its competitors. It's designed with a 17-ounce capacity tank and can pull up to 10 ounces of water from the air per day. The auto shut-off function will turn this dehumidifier off when the tank is ready to be emptied. Plus, at less than a foot tall and only 2.5 pounds, you can easily tuck this dehumidifier into any corner space or countertop without taking up much room. And, like many smaller models, this one runs very quietly, producing just 40 decibels of noise.
According to one reviewer: "I bought this because my bathroom does not have a ventilation system and I needed something to keep as much moisture out of the air as possible. As you can see in the picture, it is small enough to fit on my bathroom sink which is convenient. You can also see the water in it from two showers. While I know it is not getting everything, I think for the price and the size, it is doing a great job.”
