The 5 Best Stackable Washers and Dryers of 2024

Best Overall

LG WM4000HWA Ultra Large Capacity Washer & DLEX4000W Large Capacity Electric Dryer

$806 at Wayfair $1,099 $798 at Home Depot $2,182 at Ajmadison.com

The LG WM400HWA washer and LG DLEX400W dryer outperformed every option we tested, offering 17 quick and impressive washing cycles with effective stain removal capabilities. We love this set because it includes technology specifically designed to clean quickly. The washer uses AI to take the guesswork out of finding the right settings for your different fabrics and types of clothing—meaning your dress shirts will get the best care.

LG’s TurboWash360 technology uses five powerful jets to deliver variable sprays that help detergent penetrate deep into fabrics and provide a more thorough clean in less time. We were able to wash two sets of sheets at a time in the washer, despite the pretty average amount of space.

This set works great using just the basic modes or its additional features. It has an allergy mode certified by the Asthma and Allergy Foundation of America to remove more than 95 percent of common household allergens like pet dander, dust, or pollen using steam. The dryer also leverages steam power to reduce wrinkles and odors in clothes.

Now, the dryer gave us some trouble when we over- or under-filled it. When we loaded the dryer all the way up, items took more time to dry completely. If we only dried a few sheets at once, they would get tangled up, be a bit damp in the middle, and need a second cycle. This is hardly a deal-breaker though; using wool dryer balls that keep items separated, or running a smaller load, fixes the problem.

The washer and dryer are also both remarkably quiet, to the point that you can’t tell they’re on from the next room. A short, sing-song chime lets you know when a cycle ends. There's no lint trap indicator on the dryer (which tells you when the lint trap is full), and the spin cycle of the washer can be noisy—but that’s a typical complaint with washing machines.

One last note: To stack these units, you'll need to buy an LG KSTK4 stacking kit.

Best Value

LG WM3400CW Stackable Washer and DLE3400W Stackable Dryer

View on Best Buy

The LG WM3400CW washer and DLE3400W dryer provide a whole lot of value, with specs and features that compare very similarly to our best overall pick. The biggest difference is that this set includes fewer cycles, lacking the TurboWash and TurboSteam cycles. If you can live without these cycles that offer quicker wash times and steam, it could save you as much as $400 in comparison.

The washer and dryer are just as big as our best overall, and very capable of handling a range of loads, from towels and clothes to bulky bedding items. Our favorite washer feature is the speed-wash cycle, which gets small loads done in about 15 to 20 minutes (compared to 60 to 90 minutes normally), even if they’re fairly soiled.

We also like the inclusion of LG’s SenseClean system that automatically adjusts the wash time and water level based on the load; it simplifies the start of your laundry routine. The washer has a cycle designed to clean and dry out the tub and gasket to prevent mold growth, which can be an issue with front-loading washers.

To stack these units, you'll need to buy an LG KSTK4 stacking kit.

Best for Energy Efficiency

Electrolux ELFW7537AW Front Load Washer & ELFG7537AW Dryer

$1,898 at Ajmadison.com View on Best Buy View on Electrolux.com

The Electrolux ELFW7537AW washer and ELFE7537AW dryer are packed with useful features and topped off with an Energy Star certification, which is why this combo is our pick for the best energy-efficient, stackable washer-and-dryer set. It isn’t just Energy Star-approved, either—this set edges out our best overall pick in terms of actual operating cost and water use, which is no easy feat.

The dryer also fits more clothes than any of the other models we looked at, so this set is a particularly great option for larger households that do multiple loads per week.

The controls on both machines are intuitive and easy to understand, with options that include a 15-minute fast wash. Other useful modes include an allergen option that’s NSF-certified, a stain-removal mode that lets you select the specific type of stain you’re dealing with, and a steam function.

The LuxCare Wash technology included in the washer is a real time-saver since it uses smart load-sensing to adjust the water and detergent automatically, temperature controls to accommodate the needs of different types of fabrics, and a variety of tumbling and spinning actions to get rid of tough stains.

We also like the dispenser system you can find in the washer; it accepts laundry pods, plus standard detergent, so you can happily stock up on and use your favorite laundry detergent in any form.

The dryer also stands out with a predictive-dry feature that avoids over-drying and wasted energy, and a large 8-cubic-foot capacity to fit bulky comforters and other large items. The instant-refresh option is a nice touch since it removes wrinkles and freshens up clothes that have been lightly worn or stored for a long period of time without rewashing.

To stack these units, you'll need to pick up an Electrolux STACKIT7X stacking kit.

Best Laundry Center

LG WashTower Laundry Center

$1,660 at Amazon $1,727 at Wayfair $1,843 at Wayfair

Laundry centers are stackable washer-and-dryer sets that you can’t unstack, with the main benefit being a centralized control panel. The other benefit is that this set comes already stacked as an integrated unit, so you don’t need any extra hardware to hold them together. Overall, they're often easier to use than standard and compact stackable washers and dryers.

Aside from those key features, the LG WKEX200HWA WashTower is our favorite laundry center because it includes all of the most important capabilities of our best overall pick, making it the perfect option if you prefer an integrated laundry center over a washer-and-dryer pair that can be unstacked.

This laundry center is a little smaller than we’d like, but acceptable for a stackable unit (and deceptively accommodating). The dryer is huge too, so there’s no issue drying large comforters, dog beds, and other bulky items.

We love that this laundry center includes the same TurboWash 360 technology used by our best overall washer because it enables remarkably fast wash cycles without compromising on soil and stain removal. It also comes with LG’s TurboSteam function and an allergen wash cycle.

The dryer lacks a tumble-dry or no-heat setting, but it does have some useful options like a rack-dry feature for drying items that could damage the drum (like shoes), and delicate items that shouldn’t be tumbled. Some of the wash and dry cycles are locked behind the ThinQ phone app (you need to download them), but connecting the app has other benefits like notifications when your laundry is done.

Best Compact

LG WM1455HWA & DLHC1455W

$898 at Wayfair $1,299 $898 at Home Depot $1,299 $898 at Home Depot

The LG WM1455HWA (and its matching dryer) takes the cake for our favorite compact pick, and is really perfect for tiny spaces. Not all of us have large, dedicated laundry rooms, and this washer (and matching dryer) stack perfectly for space-saving in a closet or corner. The set is a bit smaller than your standard washing machine, but you would never know with the amount of clothes it can safely hold and clean to perfection.

We are so impressed with the efficiency of this compact washer, noting that during our testing, we transferred clothes from the dryer and they weren't sopping wet like they can be with other models. The touchscreen was also incredibly intuitive, and the set has Wi-Fi and app connectivity to take your loads to the next level. On the app, you can check how much time is remaining and get alerts when your load is finished, too.

It's quiet, effective, and efficient, but just smaller than your standard set, which can be a real perk for those in an apartment, condo, or townhome. It might not work for a large household with lots of laundry. But to us, this is the perfect pick for a compact space.

Notably, the stacking kit is included with the purchase of the dryer.
