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

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.

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 BREEZOME 60 OZ Dehumidifier is a strong candidate for managing humidity in small bathrooms and similar spaces. It offers a decent moisture removal capacity of about 700ml per day, which suits areas up to 350 square feet, making it effective for typical small bathroom sizes. The 1.8-liter water tank is relatively large for this type of unit, so you won’t need to empty it very often. Plus, the auto shut-off feature stops the machine when the tank is full and alerts you with a red light, which helps prevent overflow and hassle.

This model is compact and lightweight, with a built-in handle making it easy to move around, which is handy if you want to use it in different rooms or in an RV. Its quiet sleep mode runs at a noise level of around 35 decibels, so it won’t disturb you at night—a bonus if you want to run it in the bathroom close to your bedroom. Energy efficiency is quite good, consuming only about 1.15 kWh over a 24-hour period, and the built-in timer offers flexible operation from 12 to 48 hours, helping avoid unnecessary power use. Maintenance is straightforward, with a washable filter and an automatic defrost feature that ensures the machine continues running well even in cooler environments. The colorful adjustable night light is a nice touch for ambiance but might be unnecessary in a bathroom setting.

Some minor drawbacks include its maximum operating temperature capped at 30°C (86°F), which limits use in hotter climates, and the modest dehumidification capacity compared to larger units if you have very high humidity. This dehumidifier is a quiet, portable, and energy-friendly choice suitable for small bathrooms facing moderate humidity and mold concerns.
