If you’re tight on laundry room space, an LG washer dryer stacking kit might be the practical solution you’ve been looking for. This hardware kit lets you safely mount your LG dryer directly on top of your washer, cutting your floor footprint nearly in half while keeping both appliances fully accessible. Whether you’re working with a compact apartment or trying to reclaim valuable square footage in a shared laundry space, stacking can transform how efficiently you use the room. This guide walks you through what you need to know before buying, how to choose the right kit for your specific models, and how to install it correctly, without costly mistakes or safety issues.
Key Takeaways
- An LG washer dryer stacking kit cuts your laundry room footprint nearly in half by safely mounting your dryer on top of your washer, reducing floor space from 54 to 27 square feet.
- Model compatibility is critical when choosing a stacking kit—always verify your washer and dryer serial numbers against LG’s compatibility matrix before purchasing to avoid safety issues and warranty voidance.
- Proper installation requires two people, correct tools (hand tools only, no power drills), and thorough leveling of both appliances before stacking to prevent vibration, misalignment, and tipping during operation.
- The most common installation mistake is skipping the level check on the washer, which causes uneven dryer seating and can lead to vibration damage and potential tipping during spin cycles.
- Genuine LG stacking kits ($150–$350) are engineered for your specific model pair and are safer and more affordable than aftermarket alternatives, especially when factoring in potential warranty claim costs.
- After installation, verify at least 1 inch of clearance around the dryer vent exhaust to prevent heat buildup and fire risk, and test gas line connections with soapy water to confirm no leaks exist.
What Is an LG Washer Dryer Stacking Kit?
An LG washer dryer stacking kit is a steel bracket assembly designed to connect your LG dryer securely on top of your washer. It’s not just a simple frame, it’s engineered to support the weight of a full-size dryer while maintaining stability during operation. Most kits include a mounting bracket that attaches to the top of the washer and a corresponding bracket on the dryer’s bottom, along with all necessary hardware and fasteners. The kit holds the dryer anywhere from 6 to 12 inches above the washer surface, depending on the model, and includes adjustable feet to ensure level installation. Without a proper stacking kit, placing a dryer directly on a washer risks tipping, vibration damage, and voiding your appliance warranties. This is not a DIY fabrication project, you’re buying purpose-built equipment made by LG’s engineers.
Why Stack Your Washer and Dryer?
The primary reason homeowners stack is space savings. A stacked pair takes up roughly 27 square feet of floor space compared to 54 square feet for a side-by-side setup, that’s cutting your laundry room footprint in half. In apartments, condos, or homes with limited utility closets, this can mean the difference between fitting your laundry appliances and having to use a laundromat. Stacking also improves workflow ergonomics for some users. Pulling wet clothes from a waist-height washer and loading them into a dryer at chest level (rather than bending to the floor) reduces strain on your back. From a design perspective, vertical stacking opens up wall space for shelving or cabinets, letting you add storage or a folding countertop above the pair. The trade-off is accessibility: you’ll need a step stool to load the top dryer, and you can’t swing open both the washer and dryer doors simultaneously. Consider your household’s actual needs before committing to the stack.
Choosing the Right LG Stacking Kit for Your Models
Not all LG washers and dryers can stack together, and not all stacking kits fit all models. Model compatibility is everything, so check your appliance serial number tags (usually on the back or inside the door frame) before purchasing any kit. LG publishes compatibility matrices on their support website, cross-reference your washer and dryer model numbers. Some models require a specific kit version, while universal kits exist for broader LG lineups, though they’re less common and not always recommended by the manufacturer. Pay attention to whether your dryer is electric or gas. Most stacking kits work with both, but gas models have additional venting considerations that affect how tightly the dryer sits atop the washer. The kit’s weight capacity matters too, dryers typically weigh 80–110 pounds, but the kit must handle that load plus vibration and movement during spin cycles. Don’t assume a cheaper aftermarket stacking kit will work: LG’s genuine kits are engineered for your specific model pair and are often cheaper than the cost of a voided warranty claim. You can order directly from LG’s parts site, through authorized dealers, or from reputable appliance retailers. Expect to pay $150–$350 for a genuine kit, depending on your models.
Step-by-Step Installation Instructions
Preparation and Safety Precautions
Before touching a single bolt, unplug both appliances or switch off their circuit breaker. If you have a gas dryer, ensure the gas line is properly shut off at the valve. Clear your laundry room completely, you’ll need access to the top, sides, and back of both the washer and dryer. Have a helper on hand: lifting a dryer safely requires two people, and someone needs to spot you while you position the bracket. Wear work gloves and safety glasses to protect against sharp edges and pinched fingers during assembly.
Read the specific installation manual that comes with your stacking kit. Layouts vary by model year and dryer type. Gather your tools: a Phillips-head screwdriver, an adjustable wrench, a level (digital is easier), and a socket wrench set if the kit uses bolts rather than screws. Don’t use power drills on appliance fasteners, hand tools give you better control and prevent overtightening, which can crack mounting brackets.
Installing the Stacking Frame
-
Position the washer and dryer side by side in their final locations, ensuring both are level before stacking. Adjust the front feet of the washer and dryer independently until each unit sits flat on the floor. A tilted base leads to vibration and misalignment once stacked.
-
Attach the mounting bracket to the top surface of the washer according to your kit’s diagram. This bracket typically bolts to the washer’s top panel or to threaded studs built into the cabinet. Tighten all fasteners by hand first, then with a wrench, checking alignment after each one. The bracket should sit flush and square, no gaps.
-
Attach the dryer bracket to the bottom of the dryer. Locate the designated bolt holes or studs on the dryer’s underside: they’re pre-drilled or threaded during manufacturing. This is where your helper earns their keep. Tilt the dryer back (never tip it forward, you risk crushing the control panel) so you can access the underside, then secure the bracket. Have your helper stabilize the dryer to prevent tipping.
-
Carefully lift the dryer and position it onto the washer’s mounted bracket. This step is critical, dryers are heavy (80–110 pounds), and an awkward lift can cause back injury or dropping the unit. Use a dolly with a strap or two people coordinating the lift. Align the dryer bracket with the washer bracket, then slide them together until they mate fully.
-
Lock the brackets together using the provided fasteners. Depending on your kit, this might be bolts, pins, or a sliding lock mechanism. Secure all connection points and ensure there’s no play or movement between the two units.
-
Check level and stability with your spirit level. The stacked pair should be plumb (vertical) and not rock when you gently push on the top dryer. Adjust the dryer’s feet if the kit has them: some designs include leveling legs.
-
Plug in or reconnect power and gas lines only after the unit is fully secured and level. Reconnect the dryer’s exhaust vent, ensuring no kinks or compression. For gas dryers, double-check the gas line connection and test for leaks using soapy water (bubbles indicate a leak: call a professional if you find one).
-
Run both appliances through a test cycle. Start with a short, empty wash and dry to confirm vibration is minimal and both units operate correctly.
Common Installation Mistakes to Avoid
Skipping the level check: The single most common error is not ensuring the washer is level before stacking. A washer tilted even slightly will cause the dryer to sit unevenly on top, leading to vibration, premature wear on the bracket, and potential tipping during spin cycles. Spend five minutes on this: it saves hours of trouble later.
Using the wrong stacking kit: Buying a kit designed for a different model, or worse, a cheap universal kit with no LG engineering, is tempting but dangerous. The dryer can slip, shift, or fail catastrophically. Always verify compatibility before ordering.
Overtightening fasteners: It’s tempting to use maximum wrench force, but over-torquing bolts cracks plastic mounting blocks or strips threads. Hand-tight plus a quarter turn with a wrench is usually sufficient. Consult your manual for specific torque specs if provided.
Forgetting to account for dryer vent clearance: When you stack the dryer higher, its vent exhaust outlet may be closer to walls or cabinetry. Ensure at least 1 inch of clearance around the vent opening to prevent heat buildup and fire risk. Some laundry rooms require repositioning ductwork after stacking.
Not securing the gas line properly: Gas dryer installations involve a flexible connector line that can kink or disconnect if not routed carefully and secured with a bracket. A loose connection is a safety hazard: tighten all fittings and test for leaks before using the dryer. Better yet, have a licensed technician handle the gas line if you’re uncomfortable with it.
Failing to unplug before installation: Working on appliances with power connected, even standby power, is risky. Unplug both units and flip the circuit breaker to off. Label the breaker so no one resets it while you’re working.
