10 Best Small Bathroom Dehumidifier For High Humidity And Mold 2025 in the United States

The hOmeLabs 1,500 Sq. Ft. WiFi-Enabled Dehumidifier is a solid choice for those dealing with high humidity and mold in small to medium-sized bathrooms. It can remove up to 22 pints of moisture per day, making it effective for improving air quality in spaces up to 1,500 square feet. The WiFi-enabled smart functionality is a great convenience, allowing you to control the dehumidifier remotely, which is perfect for maintaining the desired humidity levels without constant manual adjustments.

This model also features a modern, portable design with built-in wheels and handles, enhancing its portability and ease of relocation within your home. Additionally, its quiet operation ensures minimal disturbance to your daily activities or sleep. On the downside, weighing 36.3 pounds, it might be slightly heavy for some users to move around. Energy efficiency is a plus, as it runs continuously with an automatic shut-off when the tank is full, or it can be set up for continuous drainage.

The washable filter adds to its ease of maintenance, though regular cleaning is necessary to ensure optimal performance. For a bathroom with high humidity and mold issues, this dehumidifier offers effective moisture removal with added conveniences such as remote control and portability.

The TABYIK 42oz dehumidifier is a compact, portable option that works well for small spaces like bathrooms, bedrooms, closets, and even RVs. Its 42-ounce water tank provides decent moisture removal capacity for areas up to about 320 square feet, which suits many small bathroom setups facing humidity and mold issues. It runs quietly thanks to advanced semiconductor technology, making it unobtrusive for daily use or overnight.

The unit uses just 40 watts, so it’s energy efficient compared to larger models. A helpful auto shut-off feature stops the device when the tank is full to prevent leaks, and an indicator light reminds you to empty it. It also has an automatic defrost mode, allowing it to work reliably in cooler temperatures. Since it relies on semiconductor cooling, it performs best in rooms warmer than 68°F with at least 60% humidity, so it’s less effective in colder or drier conditions.

This model balances quiet, compact design with decent moisture removal, making it a good fit for small bathroom spaces where noise and footprint matter, although it may not suit very cold or large damp areas.

The TABYIK 35 OZ Small Dehumidifier is designed for use in small rooms, bathrooms, RVs, and closets, making it suitable for spaces up to 280 sq. ft. With a capacity to collect up to 16 oz of water per day, it performs reasonably well in high humidity conditions. Its compact size (5.9 x 5.9 x 10.1 inches) and lightweight build (2.19 pounds) make it easy to move and place anywhere.

Additionally, it features auto shut-off protection, which ensures safety by stopping operation when the water tank reaches 700-800ml full. The transparent 35 oz tank allows you to monitor water levels easily, and the groove design facilitates straightforward water disposal and cleaning. The dehumidifier operates quietly at 28dB, contributing to a peaceful environment, suitable for bedrooms and offices.

The colorful light feature adds a pleasant ambiance but might be seen as a gimmick by some users. Energy efficiency is commendable, with low consumption of less than 1-kilowatt hour per day. However, it lacks continuous drainage and advanced filtration, which might require regular manual emptying and cleaning. It's a practical choice for small spaces suffering from humidity and mold, but users looking for more advanced features might need to explore other options.
