You are choosing between two setups: a single unit that washes and dries in one drum, or a tower with a separate washer and dryer. The single unit saves you from moving wet clothes between machines, but the separate dryer often finishes loads faster. Here is how three leading LG models compare for your space, your outlet, and your patience for long cycles.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Here’s what matters most when shopping for a 27 inch stackable washer dryer, explained in plain language so you can decide with confidence.
Our Picks at a Glance
How To Choose The Best 27 Inch Stackable Washer Dryer
Before you pick a model, you need to know whether your laundry room has a vent, what kind of electrical outlet you have, and how much floor space you can spare. These three factors decide which of the following LG machines will actually work in your home.
Vented versus ventless drying
A traditional stackable set uses a vented dryer that pushes moist air outside through a duct. An all-in-one combo uses a ventless system that condenses the moisture and drains it away, so you can install it anywhere without cutting a hole in your wall. If you live in an apartment without exterior venting, a ventless combo is your only realistic option.
Power requirements: 120V versus 240V
Most full-size electric dryers need a dedicated 240-volt circuit, which often requires an electrician. The all-in-one combo in this list runs on a standard 120-volt household outlet, meaning you can plug it in like any other appliance. Check your laundry area before buying, because this single difference can save you hundreds in installation costs.
Capacity and cycle time trade-offs
A separate washer and dryer finish a load in about an hour because the dryer uses more heat. An all-in-one combo washes and dries in the same drum, which typically takes much longer — sometimes several hours. If you need laundry done fast for a big family, a tower with two separate machines usually wins on speed.

In‑Depth Reviews
1. LG WKE100HWA WashTower Stacked Smart Laundry Center
Our pick — over 4★ from 30+ verified ratings; the strongest balance of quality and price.
One tower with a real dryer that finishes loads fast, built for families who hate waiting.
This is the pick for households that wash big loads daily and want them dry in a reasonable time. It pairs a 4.5 cubic foot front-load washer with a separate 7.4 cubic foot electric dryer stacked in a single 27-inch-wide tower, so you get two dedicated machines without taking up extra floor space. The separate dryer is the key advantage here — it uses real heat to finish a load in about an hour, unlike all-in-one combos that can run for hours.
Owners call it quiet, spacious, and easy to control, with several noting it cleans better than the laundromat. The washer’s drum matches the same 4.5 cubic foot size as the premium tower below, but this model’s energy use is higher at 607 kilowatt hours per year against the other tower’s 210 kWh. That’s a real gap on your utility bill, though it still balances performance with efficiency for most homes. The one-piece design stands 74.38 inches tall with a door-open depth of 55 inches, so measure your space before you commit.
Buyers find the Wi-Fi connection helpful, and the loaded height suits a 5’6″ user perfectly. The recurring trade-off is the unit’s weight — it’s a heavy one-piece tower that’s genuinely hard to move once installed, so plan your delivery spot carefully. The rare defect story involves a dryer failing after 10 weeks with frustrating warranty service, but that sits against a strong run of five-star experiences praising the cleaning and convenience.
What wins people over
- Separate 7.4 cu. ft. dryer finishes loads fast
- Quiet operation and easy controls
- Cleans better than a laundromat, per owners
Where to be careful
- Uses 607 kWh/year — more than the other tower
- Heavy one-piece unit is hard to move
- Needs 55 in. of depth with doors open
Reach for this if: you want a true separate dryer that finishes laundry quickly for a busy family.
Look elsewhere if: energy bills are your top concern — the other tower cuts annual use by roughly two-thirds.
2. LG WashTower WKE100HVA Stacked Smart Laundry Center
The leaner twin of the top pick, sipping a third of the energy with the same tower footprint.
If you want the same 4.5 cubic foot washer and 7.4 cubic foot dryer stacking layout but care about your electric bill, pick this version. Both WashTower models are 27 inches wide and 74.38 inches tall, but this one is ENERGY STAR certified (a government-backed label for energy efficiency) and uses only 210 kilowatt hours per year — that is 2.9 times less than the 607 kWh of the WKE100HWA. Over a year of heavy laundry, you will see the difference on your utility bill.
The layout is the same clever single-tower idea, with a center control panel that puts both machines at a comfortable reach. It’s also shallower with the door open — 30.38 inches against the other tower’s 55 inches — so it fits tighter hallways and smaller laundry closets. Owners call it top quality and reliable, noting the smart features are easy to ignore if you just want a plain washer and dryer. Owners praise the build quality most, with cleaning effectiveness a close second.
The catch is sound: buyers report it’s louder than expected, so it may not be the best pick for an open-plan living space right next to a bedroom. Delivery earns consistent praise for arriving early, a nice bonus on a heavy appliance. A rare experience involved the washer stopping four months after purchase, but the overall owner sentiment remains strongly positive on build quality and daily performance.
The energy story
- 210 kWh/year — dramatically less than the sibling tower
- Shallow 30.38 in. door-open depth fits tight spaces
- Center control panel is easy to reach
The honest limits
- Louder operation than owners expected
- Same heavy one-piece unit, hard to shift
Pick this one for: the lowest energy use in a full-size separate washer and dryer tower.
Think twice if: noise sensitivity matters — the WKE100HWA above runs quieter per owner reports.
3. LG 5.0 cu. ft. Mega Capacity All-in-One Washer Dryer Combo
A plug-and-play single drum that washes and dries in place, perfect for apartments with no vent.
This is the machine for renters and small-space dwellers because it removes the two biggest installation headaches: it plugs into a standard 120-volt outlet (the same as a regular appliance) and uses a ventless drying system (no outside exhaust pipe needed), so you skip the electrician and the venting work. You load dirty clothes, walk away, and come back to clean dry laundry — no transfer between machines.
The trade-off is speed. Because one drum both washes and dries, a full cycle can stretch to several hours, and some owners mention jeans taking up to 8 hours while a quick wash rinses poorly. Drying performance and cycle time draw mixed reviews — clothes come out dry, but you must plan ahead. The 120V plug and ventless design also mean it sips just 479 kilowatt hours per year, and One owner reports cutting electricity use by roughly 50% versus their old separate machines..
Owners who love it describe waking up to finished dry clothes after setting a load before bed, and praise the large drum and smart features like the auto detergent dispenser and over-suds detection. The main recurring gripes are the lint trap on top being hard to access and constant softener reminders even when you don’t use softener. Buyers praise the cleaning performance most, though a few question the value given the long cycle times.
Why it fits small homes
- Plugs into a standard 120V outlet — no rewiring
- Ventless drying, installable almost anywhere
- Biggest 5 cu. ft. drum in this list
Plan around this
- Full cycles can take hours — up to 8 for jeans
- Lint trap on top is awkward to empty
- Door swings out to 57.75 in., needs clearance
Best suited to: renters and apartments where no vent exists and you can wash overnight.
skip it if: you need laundry done fast during the day — this one is a marathon, not a sprint.
Understanding the Specs
Annual Energy Consumption (kWh/year)
This number tells you how much electricity a machine uses over a typical year of laundry. Lower is better for your wallet and the planet. The two towers show the range clearly: one uses 607 kWh per year while the other uses just 210 kWh, so the same-size machine can have very different running costs depending on its efficiency design.
Depth With Door Open
This is the total floor space the machine needs when its doors are fully swung open for loading. It matters more than you’d think — a model that measures 30.38 inches deep with the door open fits a narrow hallway, while one that reaches 57.75 inches needs a much larger open area in front. Always measure your laundry room before choosing.
