LG WM6998HBA all-in-one washer dryer vs WKHC252HWA WashTower: one drum or two?

A laundry space can hold one machine that washes and dries the same load, or a vertically arranged pair that lets washing and drying occur in separate drums. The LG WM6998HBA is an all-in-one ventless washer-dryer with a listed 5.0-cubic-foot capacity. The LG WKHC252HWA WashTower combines a 5.0-cubic-foot front-load washer and a 7.8-cubic-foot ventless heat-pump dryer in one stacked unit. Both use a heat-pump drying approach in their saved descriptions, yet their work rhythm and room shape differ. The first question is how many loads have to move through the laundry area in a day.

The LG WM6998HBA all-in-one washer dryer is listed at $3,449.84 in the September 30 catalog snapshot. The Black Steel unit washes and dries clothing in one drum using Advanced Inverter HeatPump technology. LG's listing gives a two-hour wash-and-dry time, without specifying the load size, fabric mix, or settings behind that figure in the saved excerpt. Treat it as a manufacturer claim to investigate for the household's usual load, not a promise for every basket of towels or bedding.

The related guide to washer closet-depth fit uses another machine to show why a stated cabinet dimension is only part of installation planning. It does not establish the fit of either LG model. The LG WKHC252HWA ventless WashTower is listed at $3,759.06. The white 27-inch tower has Center Control, TurboWash 360 with five variable-spray jets, a 5.0-cubic-foot washer, and a 7.8-cubic-foot electric ventless heat-pump dryer. Its ThinQ app offers remote laundry control and proactive maintenance tips. The row says a large wash load can finish in under 30 minutes with TurboWash, but it gives no matched drying time.

Follow two baskets through an ordinary laundry day — LG WKHC252HWA ventless WashTower

The all-in-one's appeal is that one load can stay in the same drum from wash to dry. A person can start it, leave for work, and avoid transferring wet clothes. That is useful for a single daily load or a household where forgetting the transfer is a common problem. The limitation is workflow: while that drum is drying, it cannot begin washing a second load. The catalog's two-hour claim needs a look at the load and cycle conditions, especially if the family regularly handles towels, jeans, or bulky items.

The WashTower has physically separate washer and dryer drums. After a wash finishes and clothes are transferred, the washer can begin another load while the dryer works on the first. That overlap can shorten the time to clear several baskets even if any one dry cycle takes longer than expected. It also requires someone to be present for the transfer. A household doing laundry once each weekend may value the overlap more than a household doing one small load most evenings. Write the sequence of loads on paper; the answer becomes clearer than a single advertised cycle-time number.

The tower's 7.8-cubic-foot dryer is larger by stated volume than its 5.0-cubic-foot washer. That pairing may give washed clothing room to tumble, subject to the manufacturer's load guidance. The all-in-one row lists 5.0 cubic feet for the appliance, but does not state a separate maximum drying load in the excerpt. Ask for LG's wash and dry capacity guidance for the combo. A drum can physically hold many items while a satisfactory drying result requires a smaller or different load. A capacity label alone does not settle the weekly schedule.

Draw the room in three dimensions — guide to washer closet-depth fit

The WashTower's saved row says it is 27 inches wide and stacked, with controls placed centrally. It does not give height, depth, door swing, or required service and ventilation clearances. The all-in-one's saved excerpt provides no exterior measurements. Get installation diagrams for both exact models and measure the room's width, depth, height, doorway, stair turns, and path from the delivery vehicle. A machine that fits inside a laundry closet may still fail to pass through the hall or leave room for hoses and a power connection.

The related closet-fit guide is a reminder to add the door-open space and the hardware behind the cabinet. Check water lines, drain placement, outlet location, floor level, and room for the appliance to be serviced. Ventless drying eliminates a traditional exhaust duct in these saved descriptions, but it does not remove every installation requirement. Heat-pump machines still need the conditions specified by the manufacturer, and water from the process must be handled as instructed. Do not assume either model can be sealed inside an unventilated cabinet because it has no exterior dryer vent.

Think about body reach as well as floor area. A tower puts a dryer opening above a washer while Center Control brings the controls to a central position. The row does not give door heights or a reach measurement. A shorter user, a person with limited mobility, or anyone handling heavy wet bedding should check the openings in a showroom or from precise diagrams. The all-in-one keeps one door at one level, which may ease transfers but also places the wash and dry work in that single drum. A laundry room's best fit includes people and baskets.

Compare time claims without combining unlike cycles — LG WKHC252HWA ventless WashTower

LG's two-hour statement for the WM6998HBA is a wash-and-dry claim in the saved listing. The WashTower's under-30-minute statement is for a large wash load using TurboWash 360; it is not a wash-and-dry total. Combining those numbers in a simple speed ranking would mislead. Ask each product's current documentation for conditions, settings, and typical times for the household's main fabrics. A cold wash with light shirts, a deep-clean cycle, and a full bedding load are different tasks.

The tower's five variable-spray jets are part of the described TurboWash system. The saved row does not provide a matched stain-removal test against the all-in-one, so a wash-time claim should not become a cleaning-quality verdict. The combo uses Advanced Inverter HeatPump technology for drying, while the tower calls its dryer a ventless heat-pump unit. The excerpts do not report energy use per cycle, moisture left in a typical load, or noise in the same test room. Check current energy labels and manuals if those costs will influence the decision.

A simple home time study can help after installation. Note when each typical load starts, when washing ends, when drying ends, and whether clothes are dry enough for storage. Keep load sizes and settings in the record. For the WashTower, include the time until someone transfers the load; a fast washer followed by a two-hour wait for a transfer will not clear the basket quickly. For the combo, include any additional dry time needed for bulky fabrics. This observation can validate the buying assumption without pretending the catalog figures measured the household.

Plan upkeep for a heat-pump routine — LG WKHC252HWA ventless WashTower

Both models use heat-pump drying according to the saved rows. The exact cleaning steps, lint-filter layout, and water-handling details are not given in the excerpts. Read the current manual for the model being purchased and identify what must be cleaned after each load and what needs periodic care. A blocked lint path or neglected filter can affect drying, regardless of the advertised technology. Place the unit so routine maintenance points remain accessible without dragging a heavy appliance out of the closet.

The all-in-one has one drum and a wash-to-dry sequence. Check how lint is captured and whether a maintenance cycle or filter cleaning is needed between different fabrics. The tower has separate washer and dryer drums; check the washer's drain-pump access and the dryer's lint and heat-exchanger guidance. These are questions for the manuals, not claims that one design has fewer chores. A household with pets or fleece fabrics should pay particular attention to how the actual machine handles lint.

The WashTower's ThinQ app and Proactive Customer Care may make reminders or alerts easier to notice. The saved combo row does not mention comparable app features. That absence is not proof it lacks them; check current specifications if remote monitoring matters. An alert cannot clean a filter or move a load, but it can make the task harder to forget. Confirm network requirements and which features remain available if the household prefers to operate appliances only from their local panels.

Installation, service, and risk — LG WKHC252HWA ventless WashTower

A tower sold as one unit can simplify matching its washer and dryer, while an all-in-one occupies a single drum position. The exact installation labor, electrical circuit, plug, and water-connection requirements must come from the model manuals and the home's infrastructure. Do not assume two appliances with ventless drying share the same outlet requirement. Before checkout, show an installer the complete room measurements and model numbers. Ask whether existing water and drain connections are suitable and whether any delivery restrictions apply.

Consider what happens if one function needs service. The WM6998HBA combines washing and drying in one appliance, so a fault could affect the whole laundry routine. The WashTower has separate mechanisms but is sold as a single stacked unit; its service access and parts arrangement require model-specific review. The saved catalog does not provide failure rates or repair-time comparisons. Check warranties, local service coverage, and how the appliance can be moved for repair. Plan a fallback laundromat or shared machine if laundry is essential to work uniforms or caregiving.

The current catalog amounts are high enough to make return and delivery terms important. Inspect the unit at arrival for shipping damage, model-number mismatch, and missing parts. Verify the doors open in the chosen space before the installer leaves. Run an initial cycle according to LG's instructions and check for leaks or unusual warnings. A clean source receipt and live product page establish the offer's identity, but only the installed unit can prove it works with the home's hookups and floor.

Price and the most useful question — LG WKHC252HWA ventless WashTower

The tower's saved $3,759.06 price is $309.22 above the combo's $3,449.84. Actual checkout totals may differ. The tower buys a separate 7.8-cubic-foot dryer and the ability to wash one load while another dries. The combo buys a one-drum wash-to-dry workflow and may avoid a transfer in the middle of a day. The price gap should be weighed against the number of weekly loads and the available height, not treated as a score for cleaning or durability.

Choose WM6998HBA when one-load convenience is central and the actual space and cycle performance fit the household. Ask for dry-load guidance and measure the machine before ordering. Choose WKHC252HWA when multiple loads need to overlap and the room can safely fit a 27-inch-wide stacked unit with usable reach and service access. Verify installation diagrams, electrical requirements, and current warranty terms for either. A drawing of the laundry space and a schedule for two typical baskets will reveal which design removes more work from the household's week.
