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 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 Bathrooms
Bathroom7.6Capacity8.5Noise5.0Temperature Stability5.1Type:RefrigerantSee all our test resultsDrain Pump:YesThe best dehumidifier for bathroom use we've tested is the GE APYR50LC. This full-size unit can quickly deal with ambient moisture in the largest, most humid of bathrooms, thanks to its high 50-pint capacity. At 1.7 gal (6.6 L), its water tank is a tad on the smaller end for something with this level of humidification capacity, meaning that it'll fill up pretty quickly. Thankfully, you can set it up to run continuously and drain into an elevated receptacle like a utility sink or tub thanks to its built-in pump. This GE unit also has a humidistat, allowing it to automatically adjust its fan speed setting depending on current humidity levels.
Unfortunately, there's no getting around the fact that this is a very bulky unit, and will likely be overkill for all but the largest of bathrooms with high levels of ambient moisture. It's also rather noisy and puts out a lot of heat while running, so it can make smaller bathrooms hot and stuffy.

Best Budget Dehumidifier For Bathrooms
Bathroom7.3Capacity6.1Noise7.9Temperature Stability8.0Type:RefrigerantSee all our test resultsDrain Pump:NoIf you're shopping for a bathroom dehumidifier on a budget and have a smaller bathroom that doesn't require the same level of dehumidification capacity, consider the Waykar PD160B. Its 8.5-pint capacity is far less than that of the 50-pint GE APYR50LC, but that should still be sufficient for most small and medium-sized bathrooms. Its much smaller design makes finding a spot for it in your bathroom easier, and it emits a lot less heat, so it won't make your bathroom feel quite as stuffy. Like the GE, this unit has a built-in humidistat, so you can set your desired humidity level and have it automatically adjust its fan speed to match, so you won't need to fiddle with the settings constantly. The hands-off operating method is for the best, as its display is dim and hard to read unless you're looking at it head-on.
Its 2.5 L water tank is a little on the small side, so you'll need to empty it fairly often if you're dealing with really high humidity levels in your bathroom. Its auto-off switch prevents the tank from overflowing when it's full, and it can be configured to drain continuously. However, it lacks a built-in drain pump, so you can't drain it into an elevated sink, high-walled tub, or really any other receptacle above ground level.

Best Dehumidifier For Small Bathrooms
Bathroom5.8Capacity2.5Noise8.0Temperature Stability8.1Type:Thermoelectric (Peltier)See all our test resultsDrain Pump:NoIf you have a really small bathroom or need a dehumidifier for a camper or RV bathroom, the ProBreeze PB-03 might be worthwhile. It's roughly half the size of the relatively compact Waykar PD160B, making it a great option for bathrooms where free space is at a premium. This tiny size comes at a cost to performance: the PB-03's dehumidification capacity is poor, and it'll struggle to deal with moisture efficiently in anything larger than a walk-in closet-sized bathroom. It also consumes very little energy while running, though its low dehumidification rate means it's far from what we'd call efficient.
On the upside, you won't have to worry about making your bathroom feel stuffy; it emits minimal heat while running, which is great if you have to leave it on for hours at a time. While there's no drain spout, it does have an automatic shut-off, so you won't have to worry about its tank overflowing.
This model can be hard to find at online retailers. If so, or if you need something truly tiny, check out its smaller sibling, the ProBreeze PB-02. It's more compact and quieter but has a smaller 9-ounce capacity and a tiny 0.1-gal (0.5 L) water tank, so it's really only suited for the smallest apartment or RV bathrooms.

The Midea MAD35S1QWT is a 35-pint dehumidifier. It has a lower capacity than the GE APYR50LC, but it's quieter and produces less heat, making it a better option for smaller bathrooms. That said, it lacks a drain pump and takes up just as much room.
