The short version

The LG WashTower answers a question a lot of homeowners eventually ask: what if the washer and dryer were one integrated unit instead of two separate appliances? Not a combo machine that washes and dries in the same drum, but a true stacked set built as a single product from the ground up.

The result is a machine that fits in roughly half the floor space of side-by-side units without compromising on capacity. The 4.5 cubic foot washer and 7.4 cubic foot dryer are full-sized. Both operate simultaneously and independently. The Black Steel finish runs the full height of the unit for a clean, intentional look.

Who this review is for: Households with limited laundry space who want full-capacity washer and dryer performance without side-by-side placement. Particularly good for condos, townhomes with small laundry closets, and anyone doing a laundry room renovation with space as a constraint.

Performance in real use

Both the washer and dryer perform at the level you would expect from standalone LG units of the same capacity. The washer's 1300 RPM spin speed is the same as the standalone WM4000HBA, which means moisture extraction and dry times are equivalent.

The dryer's 7.4 cubic foot drum handles the full washer load without needing to split it. Steam refresh cycles in the dryer reduce wrinkles on clothes pulled from the clean pile. The integrated controls between washer and dryer are intuitive once you spend a few minutes with the panel.

The biggest practical advantage is the footprint. In a standard laundry closet where side-by-side units would not fit, the WashTower works. That is not a minor convenience for the households it is designed for.

Our verdict

The best stacked laundry solution for space-constrained homes

The LG WashTower is the right answer when floor space is the constraint and you refuse to compromise on laundry performance. Full-capacity machines, integrated design, simultaneous operation, and LG's reliable ThinQ platform make it a complete package.

The price premium over buying a washer and dryer separately is real. What you are paying for is the integrated design, the footprint reduction, and the cleaner aesthetic. For the households this is built for, those things are worth the premium.

Frequently asked questions

Can the washer and dryer run at the same time?
Yes. Unlike a combo washer-dryer that uses one drum for both functions sequentially, the WashTower has two completely separate drums that operate independently. You can run a wash load while the dryer finishes a previous load simultaneously.
What happens if one unit breaks?
Each unit is serviced independently. A repair to the washer does not require taking apart the dryer, and vice versa. The integrated structure does mean you cannot replace just one half with a different brand unit if you wanted to upgrade one side.
