With so many sources of ambient moisture and sometimes insufficient ventilation, it'll be no surprise that bathrooms are a pretty ideal breeding ground for mold. If you want to get that problem under control, it might be time to invest in a dehumidifier. There's no need to invest in a whole-home unit if the problem is localized to a single room, and there's no shortage of portable units that can easily handle bathroom moisture. Some even come with handy features like a drain pump, allowing them to run continuously and have any accumulated moisture pour out of a window or into a sink or tub.
If you're looking for a more general set of recommendations, see our picks for the best dehumidifiers, the best dehumidifiers for basements, and the best dehumidifiers for bedrooms. If you have a mold problem, it's a good idea to invest in more than a dehumidifier; check out our recommendations for the best air purifiers for mold.
If you don't know where to start, deciding between dehumidifiers can put a damper on your day. Luckily, we've streamlined the process, buying and testing over 20 dehumidifiers from major retailers; no cherry-picked models. Our lab team then measures airflow, capacity, and more to ensure you have the data you need to make a buying decision. If you're still between models, you can compare them directly, side by side.

Best Dehumidifier For Large Bathrooms
Bathroom7.7Capacity8.5Noise5.6Temperature Stability6.2Size:7.0Drain Pump:YesNoise:5.6See all our test resultsWater Tank Capacity:1.6 gal (6.0 L)The Midea MAD50PS1AWT-C is the best dehumidifier for large bathrooms we've tested because of its high moisture-removal capacity, strong airflow, and convenient drainage options. It can quickly reduce humidity after showers, help prevent condensation on mirrors and walls, and keep consistently muggy bathrooms more comfortable. Its shorter, shallower body also gives it a better shot at fitting beneath a pedestal sink or in bathrooms with tight vertical clearance. Its water tank is fairly small relative to its 50-pint capacity, so you'll likely need to empty it often if you're using it in a particularly humid bathroom. Fortunately, the built-in drain pump lets you bypass the tank altogether and continuously send water to a nearby sink or other elevated drain. It also comes with a humidistat and Wi-Fi connectivity, allowing you to monitor and adjust it remotely via its companion app.
That said, it's still a loud unit that won't fade into the background while you're getting ready or unwinding in the bath. It also throws off a noticeable amount of heat during extended use. And while its relatively short profile makes it easier to place than some full-size models, it still takes up a fair amount of floor space, so you'll want a larger bathroom with enough room to accommodate it comfortably. You can purchase this unit from Costco's website.

Best Dehumidifier For Average Bathrooms
Bathroom6.9Capacity6.5Noise6.6Temperature Stability6.2Size:6.7Drain Pump:NoNoise:6.6See all our test resultsWater Tank Capacity:3.2 gal (12.0 L)If the 50-pint Midea above is more dehumidifier than your bathroom needs, the Midea MAD20S1QWT is a better option for most average-sized bathrooms. Its lower capacity is still enough to deal with everyday moisture from showers without stepping up to a heavy-duty model intended for much larger or consistently damp spaces. It has a humidistat that can automatically maintain your preferred humidity level, along with Wi-Fi controls for checking conditions or changing settings remotely. Its large water tank also means you won't need to empty it constantly, or you can connect a hose to continuously drain down into your bathtub or shower drain if preferred.
That being said, it's nowhere near as quick at removing moisture as the MAD50PS1AWT-C, so it's not the best choice for bathrooms that stay very humid for long periods. It also lacks a drain pump, so you won't be able to pump water up to an elevated drain, such as your bathroom sink. It's somewhat bulky as well, though it collapses to about half its size if you want to store it when not in use. It can also get pretty loud, though it won't be much more distracting than a typical ceiling exhaust fan you'd find in most bathrooms.

Best Budget Dehumidifier For Small Bathrooms
Bathroom5.9Capacity2.5Noise8.8Temperature Stability7.9Size:8.9Drain Pump:NoNoise:8.8See all our test resultsWater Tank Capacity:0.3 gal (1.0 L)If you're on a budget and only need light moisture control in a very small bathroom, like in an RV, the TABYIK DH-CS01 might be worthwhile. Its compact design makes it easy to fit on a counter or tuck into a clearance beside a toilet or pedestal sink, so it won't take up much usable space. It also runs very quietly and adds very little heat to the room. That said, it has very limited moisture-removal capacity and is better suited to light, lingering humidity than to quickly clearing the moisture left behind after a shower. Since it lacks a humidistat and continuous drainage, you'll need to turn it on yourself and empty its 1.0 L tank by hand.
