10 Best Dehumidifier For Small Bathroom 2025 in the United States

The TABYIK dehumidifier is a good choice for small bathrooms and similar spaces up to about 320 square feet. With a 42-ounce water tank, it can hold a decent amount of moisture before needing to be emptied, which is handy for reducing humidity without constant upkeep. It operates quietly thanks to its advanced semiconductor technology, so it won’t disturb your sleep or daily activities. The unit is compact and lightweight, making it easy to move around or fit into tight spots like closets or bathrooms.

Energy-wise, it uses 40 watts, which is fairly low and helps keep power costs down. It also features an automatic shut-off that stops the machine when the tank is full, preventing leaks or spills. The auto defrost function ensures it works well even in cooler conditions, though it’s best used in environments warmer than 68°F with at least 60% humidity for optimal performance. One thing to note is that it doesn’t have a built-in humidistat to automatically maintain your preferred humidity level, so it runs continuously until the tank is full.

If you want a quiet, compact, and energy-efficient dehumidifier for a small bathroom or similar space, the TABYIK offers solid performance with easy-to-use features. However, if you need smart humidity control or heavy-duty use, you might want to consider other options.

The TABYIK 35 OZ Small Dehumidifier is designed for small spaces like bathrooms, bedrooms, closets, and RVs, covering an area of up to 280 sq. ft. One of its prominent strengths is its compact and portable design, weighing only 2.19 pounds and measuring 5.9 x 5.9 x 10.1 inches, making it easy to place anywhere.

It features a 1000 ml (35 oz) water tank and can extract up to 16 oz (450 ml) of moisture daily under specific conditions (86°F and 80% RH). This dehumidifier operates quietly at 28 dB, ensuring minimal disturbance, and it includes a colorful light feature for added ambiance, which could be a nice touch for some users.

Additionally, it has an auto shut-off function that activates when the tank is nearly full, enhancing safety and convenience. Although its energy consumption is low (less than 1-kilowatt hour per day), the dehumidifying capacity might be insufficient for larger or more humid areas. The TABYIK dehumidifier is ideal for users needing a compact, quiet, and energy-efficient solution for small spaces.

The Frigidaire 22-Pint Portable Dehumidifier is designed to efficiently handle moisture in small to medium rooms, including bathrooms up to around 1,500 square feet. Its 22-pint daily capacity is a good fit for typical bathroom sizes, helping prevent mold and dampness without being oversized. The unit is relatively compact and portable, measuring about 12 by 16 by 20 inches and weighing 35.7 pounds, which means it can be moved around but isn't the lightest model out there.

It offers convenient features like an easy-to-carry 1.7-gallon water tank with automatic shut-off to avoid spills, plus an option for continuous drainage if you want to skip emptying the bucket. The built-in humidistat lets you set your preferred humidity level for consistent comfort, and the dehumidifier can operate in cooler environments down to 41°F, which is handy for bathrooms that might get chilly. Energy Star certification means it consumes less electricity, making it cost-effective to run. On the smart side, Wi-Fi connectivity allows remote control via an app and compatibility with voice assistants like Alexa and Google Home, which is a nice modern touch for hassle-free use.

On the downside, while noise levels aren't explicitly stated, portable dehumidifiers at this capacity tend to produce moderate sound, so it might be noticeable in very quiet spaces. Also, its weight might be a bit much for some users to move frequently. This Frigidaire model balances solid moisture removal with user-friendly features and energy efficiency, making it a strong choice for those wanting a reliable dehumidifier tailored to smaller bathrooms or similar spaces.
