Updated October 24, 2026
Bathrooms without a good exhaust fan stay damp long after a shower, and that moisture feeds mold on grout and ceilings. Our list of the best dehumidifiers for bathrooms compares six compact and mid-size models on size, capacity, drainage and features. To browse every model we cover, visit our Portable Compressor Dehumidifiers page.
Bathroom units need to be compact and easy to empty, so we weighed footprint and drainage alongside capacity.

What to Expect from Dehumidifiers for Bathrooms
A portable compressor dehumidifier works like a small refrigerator: a fan draws damp air over cold coils, water condenses and drips into a bucket or out through a hose, and the dried air passes back into the room. It suits bedrooms, bathrooms, basements and laundry rooms, and most units have a humidistat that holds the humidity at a level you set.
Compressor models remove far more water than small thermoelectric units, but they are heavier, hum while they run and lose capacity in cold rooms. Expect to empty the bucket regularly unless you use a drain hose or a built-in pump.
For more options, see our guides to dehumidifiers for bedrooms and small dehumidifiers. The product cards show the current price for each dehumidifier.
How to Choose a Dehumidifier for Your Bathroom
Match Capacity to the Space
Small units suit a bedroom, bathroom or closet. Mid-size units handle a damp bedroom, a living room or a small basement. Large units are for full basements, laundry rooms and spaces that smell musty or show condensation. When in doubt, a slightly larger unit running on low is quieter and more efficient than a small one running flat out.
Plan the Drainage
Every unit here has a bucket that shuts the dehumidifier off when it is full. For a damp basement, continuous drainage saves daily emptying: a gravity hose works when a floor drain sits lower than the unit, and a built-in pump pushes water up to a sink or out of a window when it does not.
Keep the Filter Clean
A washable filter protects the coils from dust. Rinse it every couple of weeks during heavy use; a clogged filter cuts airflow and capacity, and some units remind you when it needs cleaning.
How We Evaluate Dehumidifiers for Bathrooms
We rank dehumidifiers on manufacturer specifications and listing details: rated capacity and the test conditions behind it, coverage, drainage options, efficiency, controls and noise. For this list we kept only new, in-stock compressor units and left out renewed listings, thermoelectric mini units, commercial crawl space models and listings with too little data. For bathrooms we weighed footprint and drainage first, then capacity and efficiency.
Frequently Asked Questions
Is it safe to use a dehumidifier in a bathroom?
Yes, outside the splash zone. Plug it into a GFCI outlet and keep it away from the tub and shower.
Should a dehumidifier replace a bathroom fan?
No. Use both. The fan removes steam fast, and the dehumidifier dries what remains.
How long should a dehumidifier run after a shower?
Until the humidity drops back to around 50%. A humidistat handles this automatically.
Can a dehumidifier stop bathroom mold?
It helps by keeping surfaces dry. Clean existing mold first.
Final Verdict
The Hisense 35 Pint Compact Dehumidifier is the best dehumidifier for bathrooms, compact with a slide-out bucket and a 2-year warranty. For heavy use, choose the GE 35 Pint Dehumidifier. For efficiency, the Keystone 35 Pint Dehumidifier is ENERGY STAR certified.
