The 3 Best Dehumidifiers For Bathroom Use - Spring 2025

The best dehumidifier for bathroom use we've tested is the Midea MAD50PS1WS. This full-size unit has a substantial 50-pint capacity and will quickly deal with ambient moisture, even in spacious bathrooms. At 1.6 gal (6.0L), its water tank is a tad on the smaller end for something with this level of humidification capacity, but thankfully, it has a drain spout and a built-in pump, so you can empty it into a sink or drain. This unit also has tons of smart features, including a built-in humidistat that allows it to vary its fan speed automatically depending on your desired humidity. There's Wi-Fi connectivity, so you can control the device through your smartphone or with voice commands using Alexa or Google Assistant. However, it puts out a lot of heat and could quickly make some smaller bathrooms feel pretty stuffy.

If this model's upright form factor doesn't appeal to you, you could also consider the Midea MAD50PS1QWT, which boasts a similar feature set and performance but instead features a unique collapsible design, in which you can swivel the main dehumidifier unit and drop it into its own water tank when it isn't in use. Alternatively, you can remove the dehumidifier unit from the bucket and have it drain continuously into a tub or sink, though using it in this configuration will take up a large amount of real estate on your bathroom floor or vanity.

If you're shopping for a bathroom dehumidifier on a budget, consider the Waykar PD160B. Unlike the Midea MAD50PS1WS, 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. If that isn't an issue, it's a very good option for bathrooms. While the dehumidification capacity is considerably lower than that of the Midea, it still isn't terrible in this regard and will do just fine in all but the most stately bathrooms. Its much smaller design makes finding a spot for it in your bathroom easier. 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 2.5L water tank is a little on the small side, too, so you'll need to empty it fairly often if you're dealing with really high humidity levels in your bathroom. That said, its auto-off switch prevents the tank from overflowing when it's full.

If 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 already 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 space. 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-gallon (0.5L) water tank, so it's really only suited for the smallest apartment or RV bathrooms.
