6 Best Stackable Washers and Dryers for Small Spaces That Actually Perform
We found the best stackable washer and dryer sets for saving space and tackling stains.
Expert consulted: Carolyn FortéHome Care & Cleaning Lab Executive Director
Stackable washers and dryers are designed to maximize vertical space, freeing up valuable room for folding, storage, or simply moving around. Today’s stackable washer-dryer sets have come a long way from the machines of yesterday, offering larger capacities, better energy efficiency, and noticeably quieter cycles. Many newer washers even include features like improved venting systems that help prevent mold buildup, while some dryers use smart technology to communicate with the washer and automatically select the ideal drying cycle based on the load you just washed.
Our top picks:
- Best overall: LG Ultra Large Capacity Washer & Electric Dryer
- Best value: GE UltraFresh Vent System Washer & Electric Dryer
- Best single unit: LG WashTower
- Best compact: Miele Stacked Washer & Electric Dryer Set
To find the best stackable washing machines and clothes dryers, the experts in the Good Housekeeping Institute Cleaning Lab regularly test the latest models from a range of brands, evaluating ease of use, cleaning performance, and efficiency. If you’re ready to upgrade your laundry setup, these space-saving picks deliver powerful results and help keep your laundry room organized.
Pros
- Washer was the best performer in our recent test
- Both appliances have bright drum lights
- Both machines have large drums for fitting bulky loads
Cons
- Dryer and stacking kit must be purchased separately
This LG washer and dryer set stands out for combining large capacity with short cycle times, making it a great choice for households that want speed without sacrificing performance. In our most recent washing machine evaluation, the washer earned the highest overall score, driven largely by its speed. The Quick cycle finished in just 16 minutes, and it even washed larger, 8-pound loads on the Normal cycle in just over 30 minutes. Note that the dryer does need to be purchased separately, and to stack them, you’ll need to purchase the proper kit.
Despite the shorter cycles, the washer still delivered strong soil removal results in testing. While it wasn’t as gentle as some other models we evaluated, it remained reasonably kind to clothes overall. The drum has a 5.0 cubic foot capacity, making it easy to accommodate bulky loads. The automatic detergent dispensing and AI cycle adjustment features are a plus for anyone who wants to make laundry as hands-off as possible.
While we haven’t formally evaluated the dryer in this pairing, we are testing a similar model with great results. It has many useful features like AI dry, which automatically chooses the best cycle, temperature, and time by sensing the fabric texture and load size. We particularly like that the time-dry setting ranges from 10 to 100 minutes, allowing for more precise control than some other machines.
For both machines, cycle selection is handled with a central dial. Settings like temperature, spin speed, dry level, and other adjustments are accessible on an adjacent panel. The interface is intuitive, and we really appreciated the built-in screen on the dial that clearly displays each cycle’s name and description. Both machines have bright drum lights that make it easy to see inside when loading and unloading clothes.

Pros
- Steam functionality
- Works with Amazon Alexa, Android, Google and iOS smart home devices
- The appliances' drums are illuminated
Cons
- Some reviewers say the washer is loud
This sleek GE washer and dryer set comes at a great price for two full-size, fully-featured machines (you just have to buy the washer and dryer separately). The washing machine's detergent dispenser holds up to 32 loads' worth of detergent, so you don't have to worry about refilling it constantly, and it automatically dispenses the correct amount for each cycle.
While front-loading washing machines are prone to becoming musty, the washer in this set counteracts this with a fresh-air venting cycle to dry the drum interior and door gasket, which should prevent water or mold build-up that can lead to odors. Plus, moisture-prone areas like the gasket, dispenser drawer, and hose are treated with Microban to further control odors by inhibiting bacterial growth.
The washing machine has another helpful feature. For small loads or single pieces of clothing, you can wash and dry in the washing machine. This one-step wash-and-dry cycle runs for eight hours and is designed to run overnight, which is especially useful if you won't be home to transfer your laundry to the dryer. It also has a steam feature for quick refreshes.
The venting feature and overnight dry cycle (and all the other cycles, for that matter) can be activated within the app. It's easy to use and allows for voice control on Amazon Alexa, Android, Google, Sonos, and iOS smart home devices.
In addition to the efficiency and effectiveness of the wash cycles, reviewers loved the drum light's visibility and its ability to thoroughly dry the door gasket of residual moisture. On the downside, some reviewers reported that the washer is loud. The dryer can be connected to the washer so it automatically selects the correct cycle for the load coming its way.

Pros
- Easy-to-reach controls
- Excellent stain removal
- Luxurious-looking exterior and tempered-glass doors
Cons
- The machines can be separated for repairs but not to fully replace one or the other
LG's WashTower pioneered the modernized laundry center. Its innovative design combines a washer with either a gas or electric dryer in a single unit (with the dryer stacked on top). Better yet, it's 3.5 inches shorter than a traditional stacked washer-dryer pair, so it can be tucked away more easily in a closet or other tight spaces.
We were particularly impressed by the appliance's luxurious-looking exterior and tempered-glass doors. The control panel controls both the washer and dryer, and it's located between the two machines. It eliminated the need for the excessive stretching sometimes necessary to reach the dryer's controls, which was especially valued by our shorter testers. It was also easy to load and unload.
The steam option, which allows for quick refreshes of lightly worn garments, was a welcome bonus, but most impressive were its speedy yet effective cleaning cycles with excellent stain removal. The appliance uses AI to automatically select water temperature, spin speed, and drying temperature for each load, helping save energy and reduce laundry time.
It’s also worth noting that even after five years of use, our test machine continues to function flawlessly and has remained odor-free. That said, while the machines can be separated for repairs, they cannot be replaced or swapped out on their own—they come as a single unit.
Features at a Glance
| Dimensions | 27" x 74.34" x 30.34" |
| Washer capacity | 4.5 cu. ft. |
| Dryer capacity | 7.4 cu. ft. |
Pros
- Variety of specialty cycles available
- Only about 23 inches wide
Cons
- Not ideal for larger loads of laundry
At just under 24 inches wide, this combo unit is great for those who don't have enough space for full-size units. The drum of the washer is surprisingly large at 2.26 cubic feet, while the drum of the matching dryer is 4.2 cubic feet—roomy enough to accommodate average loads for smaller families.
Despite its small size, it packs many convenient features like self-dispensing detergent and SoftSteam, which allows you to steam your clothing inside the machine. The washing machine also has cycles tailored to synthetic and outdoor fabrics. As for the dryer, it has a honeycomb structure that, according to the brand, is more gentle on clothing and helps the laundry dry more uniformly.
Our Cleaning Lab tests also found that it was incredibly effective, removing stains and whitening cotton swatches in under an hour. Miele said it also tested this product by running it for more than 10,000 hours to make sure it could hold up to years of use. While the drum sizes are impressive considering the units' small footprint, they are not designed to handle large loads of laundry.

Pros
- Good value for combo unit
- Offers the benefits of a top loader in a stackable unit
- Good for limited spaces
Cons
- Machines cannot be swapped or replaced independently
- Some reviewers report that it's noisy
For those who prefer the speed, ease of loading, and cleaning power of a traditional top-load washer but lack the space for separate units, GE offers a unique laundry center solution. The GE Unitized Spacemaker combines the space-saving design of stackable washers and dryers with the benefits of a top loader, including a built-in agitator for tough stains.
While this option lacks some of the more premium features, such as an accompanying app and delayed start, it offers great value. Not only does it have the unique top-loading feature, but it also offers 11 wash cycles and sensors that determine load size, so the machine automatically adds the right amount of water. And while there is no app for live updates on your laundry, indicator lights show the cycle's progress as it runs.
Measuring in at 3.8 cubic feet, the washer is spacious enough for bulkier loads like bedding. The appliances' biggest downfall is that if one machine breaks, you will have to replace both since they are fully attached. Also, some reviewers reported that it's noisy.

Pros
- Has convenient features like a reversible door, interior light, and 15-minute speed cycle
- SmartBoost and StainSoak features effectively treat stains
- Detergent dispenser has a place to insert packs
Cons
- It doesn’t have Wi-Fi for monitoring or controlling cycles remotely
Electrolux’s Smartboost washing machine mixes detergent with water before it enters the drum, improving penetration and stain removal. This feature helped the unit ace our stain removal tests. It also has a steam mode for sanitizing clothes and lifting dirt out of fabrics. We also appreciated convenient features like its reversible door, interior light, and 15-minute speed cycle.
The washer includes an Adaptive Dispenser with a dedicated chamber for detergent packs, so there’s no need to toss packs directly into the tub. This solves the occasional but annoying problem of partially undissolved laundry packs. As the water hits the chamber, the pack opens, flushing the detergent into your load.
Our biggest complaint is its longer wash cycles—some are as long as two hours. It’s also worth mentioning that the Electrolux lacks Wi-Fi connectivity, so there’s no way to remotely monitor cycles.
At 8 cubic feet, the stackable dryer offers a roomy capacity and a convenient 15-minute quick cycle to freshen clothes, whether you want to smooth wrinkles or remove odors.

How we test stackable washers and dryers
The Good Housekeeping Institute Cleaning Lab regularly tests washers and dryers to find the units best suited to your cleaning needs. Our evaluations follow industry standards set by the Association of Home Appliance Manufacturers (AHAM).
In our most recent washing machine tests, we ran pre-stained fabric strips through multiple wash cycles to assess each machine’s soil-removal performance. We then took color measurements of the stained areas to calculate how effectively stains were removed.
To evaluate fabric care, we washed cotton swatches with pre-cut holes to measure fraying, observed whether items tangled excessively during cycles, and assessed the user-friendliness of each machine’s controls. For models with a sanitizing cycle, we reviewed manufacturer-provided data to confirm claims regarding bacterial reduction.
To test clothes dryers, we installed each standalone unit in a controlled climate chamber on a platform balance to ensure consistent temperature, humidity, and venting conditions. This allowed us to measure how long it took a standardized wet load to return to its dry weight. Following AHAM protocols, we also attached temperature-sensitive strips to individual items to confirm that the dryer's internal temperature remained within fabric-safe limits.
Throughout testing, we evaluated drying speed, twisting and tangling, and checked garments for wrinkles after steam and refresh cycles to verify that those features performed as intended.
What to look for in a stackable washer and dryer
✔️ Overall size: If you are stacking your appliances, you probably have size constraints, so this is crucial. If the stack is too tall or wide to fit in your space, nothing else matters. Also, remember to account for an extra 6 inches at the back for venting hoses and materials.
✔️ Capacity: We suggest choosing the largest capacity washer and dryer that will fit in your space. This will allow you to wash and dry larger loads.
✔️ Cycles and settings: Although newer models offer tons of high-end features, Carolyn Forté, the executive director of the Good Housekeeping Institute Home Care and Cleaning Lab, suggests prioritizing the wash cycles and options you'll actually use. For example, if you have many delicate items, make sure the machine has a well-reviewed gentle cycle. If you have kids or a large family, prioritize machines with power-wash features and large drums.
✔️ Warranty and availability of service: Most washing machines and dryers offer a one- to two-year full warranty on all parts and labor, and some have longer warranties on certain parts like the drums or transmission. It also pays to check which authorized service is available in your area for any brand you are considering, in case something goes wrong. You can find this out by calling the manufacturer's customer service line.
Are front-loading washers and dryers less powerful than top-loaders?
After conducting many rounds of GH Cleaning Lab tests, Forté says there are typically very few differences between front-loading and top-loading washing machines. And while some (not all!) front-loading washing machines may have an edge, Forté says "more aggressive washing action is not always better, as it can be more damaging to fabrics. Gentleness is also something we evaluate at GH, and in our opinion, the best washers offer the best combination of effective cleaning and gentle fabric care. They can be either top- or front-loading."
The most consistent difference between top-loaders and front-loaders is the most obvious: how you load them. It can be convenient to dump items directly into a top-loading machine, but they will need to be lifted out at the end of the cycle. For a front-loading machine, you will have to bend down both when loading and emptying.
What are the negatives of a stackable washer-dryer?
The main drawbacks of stackable washer-dryer sets are convenience-related rather than performance-related. “The controls on the dryer may be difficult or impossible for shorter people to reach,” says Forté. “And when stacked, the appliances are heavy to move, if they can be moved at all,” which can make servicing more difficult.
You’ll also want to confirm that you have enough vertical clearance before buying. “If you have low ceilings or cabinets above your washer and dryer, a stacked set may not fit,” Forté adds.
Are wash towers worth it?
Wash towers can be a smart choice if you want a streamlined, space-saving setup with easy-to-reach, centrally located controls. The downside is flexibility—since they’re sold as one unit, you’re locked into replacing both the washer and dryer together.
