A bathroom dehumidifier needs enough moisture-removal capacity to handle repeated showers without taking up too much floor space. I focused on verified pint capacity, automatic humidity control, drainage options, noise, size, energy efficiency, and current US availability.
Top picks

GE 25-Pint Portable Dehumidifier — Best for heavy bathroom moisture
The GE 25-pint model is my pick for large bathrooms, frequent showers, or moisture that spreads into adjoining rooms. Smart Dry automatically changes fan speed according to humidity, while the full-bucket alarm, washable filter, and continuous-drain connection reduce routine monitoring.
- This small dehumidifier for bedroom, bathroom, basement use removes up to 25 pints of moisture per day. Perfect as a room dehumidifier for humid spaces up to 1,500 sq ft.
- Smart Dry automatically adjusts fan speed based on room humidity for efficient moisture removal without over‑drying, helping save electricity compared to running the portable dehumidifier on constant high‑speed settings.
- Simplify water removal with the built-in drain hose connection for continuous drainage or use the easy‑to‑empty 8.5 pint bucket. The system will alert you with a 10-second alarm when the bucket is full or missing.
Pros
- Strong 25-pint daily capacity
- Automatic Smart Dry operation
- Continuous-drain option
- Bucket and filter alerts
Cons
- Bulky for a small bathroom

Buying guide
Choose compressor power over tiny tank size
Small thermoelectric dehumidifiers may fit easily on a counter, but their extraction rates are usually far below those of compressor models. For a bathroom used for daily showers, I would start with an eight-pint compressor unit and move toward 20–25 pints when moisture remains for hours or spreads into nearby rooms.
Use pint capacity as the main comparison
Capacity describes how much water a dehumidifier can remove in 24 hours under specified test conditions. Advertised square-foot coverage is less consistent between brands, so pint capacity, humidity conditions, and drainage setup provide a better basis for comparison.
Look for an adjustable humidistat
A humidistat lets the dehumidifier cycle off after reaching the selected humidity instead of running continuously. The EPA recommends keeping indoor humidity below 60%, ideally between 30% and 50% when possible.
Continuous drainage saves work
A hose can drain collected water into a suitable floor drain, shower drain, or sink when the manufacturer permits that arrangement. Gravity-drain systems require the hose outlet to remain lower than the dehumidifier connection; otherwise, the bucket must be emptied manually.
Do not treat it as a replacement for ventilation
A dehumidifier can help when humidity remains after a shower, but the bathroom exhaust fan should still vent moist air outdoors. The EPA specifically recommends using the bathroom fan or opening a window to control moisture.
Keep electricity away from water
Place the dehumidifier on a stable, dry surface outside the tub or shower splash zone. Follow the manufacturer’s clearance requirements, avoid extension cords, and use a properly installed bathroom outlet with required GFCI protection.
FAQs
What is the best dehumidifier for a bathroom?
The Midea Cube 20-Pint is my best overall pick because it combines substantial moisture removal, automatic humidity control, smart features, and flexible bucket or hose drainage.
What size dehumidifier does a bathroom need?
An eight-pint compressor model can suit a small bathroom with moderate moisture. A 20- to 25-pint model is more appropriate for frequent showers, larger rooms, poor ventilation, or humidity that reaches adjoining spaces.
Can I run a dehumidifier while showering?
Only place and operate it exactly as permitted by its instructions and local electrical requirements. Keep it outside splash zones and never position it where the cord, plug, or appliance could get wet.
Where should I place it?
Place it on a dry, level floor with enough open space around the air inlet and outlet. A location near the bathroom doorway can provide safer clearance from water while still drawing humid air from the room.
Should I close the bathroom door?
Closing the door can help the unit concentrate on the bathroom, provided the machine has enough airflow around it. Leaving the door partly open may work better when moisture has spread into an adjoining bedroom or hallway.
How long should it run after a shower?
Run it until the humidity returns to the selected range, commonly around 45% to 50%. Automatic humidistats make this easier because the unit can stop or reduce operation after reaching the target.
Will a dehumidifier prevent bathroom mold?
It can reduce the excess moisture that supports mold growth, but it will not repair leaks, inadequate ventilation, wet walls, or existing mold. Persistent dampness should be traced to its source.
Final verdict
The Midea Cube 20-Pint is my top bathroom dehumidifier because it offers strong extraction, automatic control, and flexible drainage without requiring an oversized 35- or 50-pint machine. Choose the hOmeLabs 8-Pint for a smaller footprint, the Frigidaire for smart controls, the GE for heavier moisture, or the Danby for simple operation.
