For large bathrooms, RTINGS names the Midea MAD50PS1AWT-C; for average bathrooms, the Midea MAD20S1QWT; and for very small spaces with light lingering humidity, the compact TABYIK DH-CS01. They are not interchangeable: the TABYIK is not built to clear heavy post-shower moisture quickly, while the larger Midea models take more space and make more noise. A dehumidifier can help manage humidity, but it does not replace a bathroom exhaust fan that removes moisture at its source.
Which bathroom dehumidifier should you choose?
| Model | Best fit | Capacity and drainage | Main trade-off |
|---|---|---|---|
| Midea MAD50PS1AWT-C | Large bathrooms and heavier moisture loads | 50-pint capacity per day; 1.6-gallon (6.0 L) tank; built-in pump for drainage to an elevated outlet | Loud, relatively bulky, and produces noticeable heat during extended use |
| Midea MAD20S1QWT | Average-sized bathrooms | 3.2-gallon (12.0 L) tank; optional hose for continuous gravity drainage | Slower in persistently humid spaces; no pump for elevated drainage; somewhat bulky and audible |
| TABYIK DH-CS01 | Very small bathrooms, including RVs, with light lingering humidity | 0.3-gallon (1.0 L) tank; manual emptying | Limited moisture removal; no humidistat or continuous drainage |
These model details and use-case recommendations come from RTINGS’ bathroom dehumidifier guide, updated September 25, 2026. RTINGS says its selections account for price, visitor feedback, and availability; confirm current model variants, stock, and local availability before buying.
Best dehumidifier for a large bathroom: Midea MAD50PS1AWT-C
Choose the MAD50PS1AWT-C when a larger room or persistent moisture calls for faster removal and you can accommodate a substantial appliance. RTINGS reports a 50-pint daily capacity, a humidistat, Wi-Fi connectivity, and a built-in drain pump. The pump can move collected water to a nearby sink or another elevated drain, which avoids relying on gravity alone.
Its 1.6-gallon (6.0 L) tank is small relative to the unit’s capacity, so tank-based use can mean frequent emptying during demanding conditions. RTINGS also describes it as loud, notes noticeable heat during extended operation, and says it still occupies considerable floor space. It is a practical fit when moisture removal and pump drainage matter more than quiet operation or compactness.

Best dehumidifier for an average bathroom: Midea MAD20S1QWT
The MAD20S1QWT is the more moderate-capacity choice for an average-sized bathroom. Its 3.2-gallon (12.0 L) tank is larger than the MAD50PS1AWT-C’s, and it has a humidistat and Wi-Fi controls. For continuous drainage, it can use a hose routed by gravity into a tub or shower drain.
This model has no pump, so the drain outlet must be lower than the unit. RTINGS says it removes moisture more slowly than the 50-pint pick in persistently humid spaces and describes it as somewhat bulky and audible. Choose it when the larger tank and a gravity-drain setup suit your room better than pump-assisted drainage.

Its moisture-removal capacity is very limited, so it is not the choice for quickly clearing heavy shower moisture. It has neither a humidistat nor continuous drainage: you must start it manually and empty the tank by hand.

How to size and compare bathroom dehumidifiers
Match capacity to the room and its conditions
Room size alone does not determine the right capacity; humidity conditions matter too. ENERGY STAR advises matching capacity to the size of the space and the conditions without dehumidification, and cautions against undersizing. The three picks above are recommended for different bathroom sizes and moisture loads, not as equivalent alternatives.
Compare efficiency using IEF
Integrated energy factor (IEF) measures liters of water removed per kilowatt-hour. A higher IEF generally indicates a more efficient dehumidifier. ENERGY STAR says certified dehumidifiers are 20% more efficient than non-certified models; its current specification took effect October 1, 2025. The cited product information does not establish comparable IEF values or operating costs for these three models under the same room conditions and electricity tariff, so a model-specific bill estimate cannot be made from these figures.

Consider drainage, controls, noise, and space together
Tank capacity does not tell you how often a unit will need attention by itself: capacity, bathroom moisture, runtime, and drainage all matter. A gravity hose needs a drain below the appliance; a pump can send water to an elevated outlet. Humidistats can automate humidity-based operation, while a model without one requires more manual oversight. Check that the physical footprint and operating noise are acceptable for the bathroom location.

Remove moisture at its source
ENERGY STAR advises using vent fans in bathrooms and kitchens to remove humidity at its source. A dehumidifier helps manage moisture in the room, but should not be treated as a substitute for suitable bathroom ventilation. ENERGY STAR gives 30%–50% relative humidity as the generally considered optimum range for a building; levels above that may promote mold growth. In colder climates, winter guidance may call for 30%–40% RH to reduce window condensation.

Keep water away from electrical hazards
- Use a properly grounded outlet.
- Keep collected water and drainage away from electrical circuits and devices.
- Route drain hoses away from cords and connections, and avoid long, unwieldy hoses that can create trip hazards.
These precautions are from ENERGY STAR’s dehumidifier saving tips. For a model without a humidistat or a useful relative-humidity display, ENERGY STAR suggests considering a separate hygrometer near the unit.
Check bathroom fan installation conditions by model
Fan suitability above a tub or shower is model-specific. Broan-NuTone says its AE50110DCS is UL listed for use over bathtubs or showers when ceiling mounted and connected to a GFCI-protected branch circuit. That condition is specific to this fan and should not be assumed for other models. The manufacturer lists selectable airflow of 50/80/110 CFM on its AE50110DCS product page.
