Best Dehumidifier for a Bathroom

A 20-pint dehumidifier is plenty for a bathroom or laundry room. The Midea Cube 20 ($180) is the top pick: compact enough to fit in tight spaces, quiet enough not to bother you, and its 3.2-gallon tank means fewer trips to empty it.

Understanding Your Needs

Bathrooms generate intense humidity spikes from hot showers but return to normal levels within an hour or two. A bathroom exhaust fan handles most of this, but if your bathroom lacks good ventilation, develops mold on grout or ceiling, or stays foggy long after showers, a small dehumidifier fills the gap. A 20-pint unit is sized right for spaces under 200 sq ft. Look for a compact footprint, quiet operation (you do not want a loud machine running while you get ready), and a washable filter that holds up in a humid environment.

Why These Picks

The Midea Cube 20 combines a compact cube design that fits in bathroom corners with a 3.2-gallon tank that is 3x larger than competitors. At 45 dB, it is quiet enough for a bathroom. Wi-Fi lets you monitor it remotely. If budget is tight, the BLACK+DECKER 22-Pint ($160) is the cheapest option that still performs.

Sizing Note

Bathrooms get a 1.1x modifier because humidity spikes from showers are intense but temporary. A 20-pint unit handles these bursts effectively.
