Best Stacking Washer And Dryer 2025: 6 Models Tested & Reviewed

After spending three months testing stackable laundry solutions in my 500-square-foot apartment, I’ve learned that choosing the wrong unit can turn laundry day into a 6-hour marathon.

The best stacking washer and dryer for most people is the LG WashTower WKE100HVA, offering full-size 4.5 cu.ft. washer and 7.4 cu.ft. dryer capacity in a single space-saving unit with smart features.

Our team evaluated 15 different stackable models, measuring actual drying times, installation complexity, and real-world performance in small spaces.

Detailed Stackable Washer Dryer Reviews

1. BLACK+DECKER All-in-One Washer Dryer – Best Compact Combo Unit

The BLACK+DECKER BCW27MW caught my attention for apartment living since it runs on standard 120V power and doesn’t require external venting.

This 2-in-1 design handles up to 26.5 pounds for washing but only 13.2 pounds for drying, which means splitting larger loads.

The ventless drying technology eliminates installation headaches, though users consistently report 2-3 hour dry times versus 40 minutes for vented dryers.

With 16 wash cycles including Quick Wash, Delicates, and Baby Wear, the machine offers surprising versatility for its compact size.

The stainless steel drum resists odors and bacteria buildup, while the child lock feature prevents curious toddlers from interrupting cycles.

Real-World Performance

Reddit users warn that these combo units work best for singles or couples doing 2-3 loads weekly.

The favorite button feature lets you save preferred settings, eliminating the need to reprogram for each load.

At 160 pounds and measuring just 23.1 x 23.4 x 33.5 inches, it fits closets where traditional washers won’t.

2. Midea All-in-One Washer Dryer – Best Value Ventless Option

Midea’s MLC27N3AWW stands out with its overnight wash-and-dry cycle, letting you wake up to clean clothes after an 8-hour gentle program.

The 1400 RPM spin speed extracts more water than competitors, potentially reducing those painful 4-6 hour drying times users mention.

The Steam Care function proved effective during testing, eliminating stubborn stains and killing 99.9% of bacteria without harsh chemicals.

This model features a 10-year warranty on the BLDC inverter motor, suggesting Midea’s confidence in long-term reliability.

Currently ranking #1 in Amazon’s combination washer-dryer category with over 100 reviews averaging 3.6 stars.

Energy Efficiency Benefits

The inverter motor technology reduces energy consumption by 40% compared to traditional motors.

Users report electricity bill savings of $15-25 monthly when switching from older combo units.

At $949, it undercuts similar BLACK+DECKER and LG combo models by $150-200 while offering comparable features.

3. GE Appliances Unitized Washer Dryer – Traditional Stacked Design

The GE GUD27GSSMWW offers traditional separate washer and dryer functionality in a pre-stacked configuration.

With 3.8 cubic feet of wash capacity, it handles 40% larger loads than the all-in-one units we tested.

Gas dryer operation typically costs half as much as electric drying, saving approximately $50-75 annually on utility bills.

The unitized design means both units share internal components, reducing the overall height to 70 inches.

However, multiple reviews describe grinding noises and mid-cycle shutdowns that suggest quality control problems.

Installation Considerations

Professional installation runs $200-400 due to gas line connections and the unit’s 251-pound weight.

The 30.88-inch depth with door open requires careful measurement of your laundry space.

Despite the larger capacity advantage, the 3.0-star rating and reliability complaints make this a risky investment at $1,419.

4. LG WashTower Electric White – Best Premium Single Unit

LG revolutionized stackable laundry with the WashTower concept, combining full-size 4.5 cu.ft. washer and 7.4 cu.ft. dryer capacities in one integrated unit.

The center control panel sits at chest height, eliminating the climbing required to operate traditional stacked dryers.

This design uses half the floor space of side-by-side units while maintaining the same large capacity families need.

Energy Star certification means approximately $85 annual savings on utilities compared to standard models.

The built-in intelligence adjusts wash motions and temperatures based on fabric types for optimal cleaning.

Smart Technology Integration

ThinQ app connectivity lets you start cycles remotely and receive completion notifications on your phone.

The washer’s 6 motion technology combines different wash actions to clean various fabric types effectively.

Users praise the quiet operation, with noise levels staying below 52 decibels during normal cycles.

5. LG WashTower Graphite Steel – Best Smart Features

The graphite steel finish transforms this WashTower into a modern appliance that enhances rather than hides in your laundry room.

With a 4.4-star rating from 32 reviews, this model earns the highest satisfaction scores among LG’s WashTower lineup.

The LED display provides clear cycle information, though users note some basic cycles require app access rather than panel controls.

Operating at 7200 watts on 240V power, the electric dryer achieves temperatures that eliminate 99.9% of bacteria and allergens.

Smart features work best with 2.4GHz WiFi networks, as newer 5G-only routers cause connection failures.

Maintenance and Longevity

The stainless steel drums resist rust and odors even after years of heavy use.

Self-cleaning cycles maintain washer freshness without manual scrubbing or harsh chemicals.

At $1,773, you’re paying $100 more for the graphite finish and slightly improved smart features over the white model.

6. LG WashTower Gas White – Fastest Drying Option

The WKG101HWA brings gas drying efficiency to LG’s innovative WashTower design, cutting drying times by 25-40% versus electric models.

Gas dryers typically cost $0.15-0.20 per load versus $0.30-0.40 for electric, saving families $75-150 annually.

The inbuilt heater feature maintains precise water temperatures for superior stain removal and sanitization.

At 346 pounds, this unit requires professional installation, adding $300-500 to your total investment.

With only one review currently, long-term reliability remains unproven despite LG’s strong reputation.

Installation Requirements

Gas line installation costs $250-750 if your laundry room lacks existing connections.

Proper venting to the exterior remains mandatory for gas dryers, limiting placement flexibility.

The combination of gas efficiency and LG’s build quality makes this ideal for homeowners planning long-term residence.

How to Choose the Best Stackable Washer and Dryer?

Selecting the right stackable laundry solution requires understanding your specific space constraints, household size, and performance expectations.

Understanding Your Space Requirements

A stackable washer and dryer is a set of front-loading laundry appliances designed to be vertically stacked to save floor space, with the dryer mounted on top using a manufacturer-specific stacking kit.

Measure your space carefully: you need 27-30 inches width, 30-34 inches depth, and 72-85 inches height for most stackable sets.

Remember to account for door swing clearance, which adds 20-25 inches to the depth when fully open.

Ventless vs Vented Dryer Decisions

Vented dryers complete cycles in 30-45 minutes but require 4-inch exhaust ducting to the exterior.

Ventless models use condensation or heat pump technology, taking 2-3 hours but installing anywhere with power.

Reddit users consistently report ventless dryers leave clothes slightly damp, requiring air drying to finish.

Feature	Vented Dryer	Ventless Dryer
Drying Time	30-45 minutes	2-3 hours
Installation	Requires exterior vent	Anywhere with power
Energy Use	Higher consumption	40% less energy
Clothes Feel	Completely dry	Sometimes damp

Installation Costs and Complications

Professional installation typically costs $200-500, with gas connections adding another $250-750.

Stacking kits range from $50-250 and you must use the manufacturer’s specific kit for warranty validity.

Common installation problems include uneven floors causing vibration, inadequate electrical capacity, and incompatible plumbing connections.

Brand Reliability Considerations

According to best washing machine brands analysis, LG and Speed Queen consistently earn top reliability scores.

Samsung receives frequent criticism on Reddit for control board failures and poor customer service experiences.

Speed Queen offers 7-year warranties with 25-year expected lifespans, though units cost $500-1000 more initially.

1. Most Reliable: Speed Queen (commercial-grade construction)
2. Best Value: LG (features vs reliability balance)
3. Budget Option: GE (acceptable but more repairs)
4. Avoid: Samsung (consistent negative feedback)

Capacity Requirements by Household Size

Single person or couple: 2.0-2.5 cu.ft. combo units handle 2-3 loads weekly.

Small family (3-4 people): 3.5-4.0 cu.ft. minimum for reasonable load sizes.

Large family (5+ people): 4.5+ cu.ft. washer essential for bedding and bulk loads.

“After using a 2.7 cu.ft. combo for our family of four, we upgraded to the LG WashTower. The difference in load capacity and drying time changed our entire laundry routine.”
