The 3 Best Dehumidifiers For Bathroom Use - Fall 2024

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 within large bathrooms. At 1.6 gal (6.0 L), its water tank is a tad on the smaller end for something with this level of capacity, but thankfully, it has a drain spout and a built-in pump for continuous drainage, even into a sink or high-walled tub once its tank has been filled. This unit is also jam-packed with smart features. It has a built-in humidistat and will automatically vary its fan speed depending on your desired humidity. It's also Wi-Fi enabled, allowing you to run the device through your smartphone or with voice commands using Alexa or Google Assistant. Unfortunately, this dehumidifier 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 necessarily have it drain into an elevated sink or high-walled tub. If that isn't an issue, it's a very good option for use in bathrooms; while its dehumidification capacity is considerably lower than that of the Midea, it's still not terrible in this regard and should do just fine in all but the most stately of bathrooms. It's also notably smaller than the Midea, making it easier to set up in most bathrooms. This unit also has a built-in humidistat, allowing you to input your desired humidity level and have it automatically adjust its fan speed to match, reducing the need to constantly fiddle with the settings.

That 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 out fairly often if you're dealing with really high humidity levels in your bathroom.

If you have an especially 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 an exceptionally good 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 efficiently deal with moisture 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 very little heat, which is great if you leave it running for hours. While there's no drain spout, it does have an automatic shut-off, so you won't have to worry about its tank overflowing.
