Two problems always occur together with the washing machine: there is too little space, and the thing makes too much noise. Both can be solved with simple means — stacking wins back a square meter of floor space, and proper leveling plus a dampening mat removes the rumbling from the floor. This article covers both, in the correct order, with the mistakes you are better off avoiding.
Stacking: why a stacking kit is not a luxury
Placing a dryer loose on top of a washing machine seems to work — until the first spin cycle. The bottom machine moves, and without a connection, the top one shifts millimeter by millimeter along with it. After weeks the dryer is crooked, after months dangerously close to the edge. A stacking kit connects both machines into a single unit, so the dryer cannot shift. Many kits also have a pull-out tray: a work surface to place the laundry basket on while loading and unloading — a small detail that you will use daily.
Stacking in four steps
- Level the washing machine first. This is the most important step and it comes before everything: turn the leveling feet until the machine no longer wobbles, check with a spirit level on top, and tighten the lock nuts. A crooked bottom machine makes a stack inevitably unstable.
- Measure and check the dimensions — width and depth of both machines; most stacking kits fit standard sizes, but measuring takes two minutes and prevents a return.
- Lift with two people. A dryer is heavy enough that it is not wise to do it alone, and you need to be able to place it on the frame in a controlled manner instead of dropping it onto it.
- Attach the stacking kit according to the manual and then check if the whole unit does not move when you push hard against the top machine.
What you should avoid: using rubber pads or wooden slats as an improvised stacking kit. They do not absorb the movement but actually allow it — which is exactly what the problem is.
The vibrating machine: level first, then dampen
The order that most people reverse. If your machine vibrates, step one is not buying a mat but leveling the machine. A crooked machine swings itself further out of balance with every spin cycle, and no mat fully compensates for that. Therefore, check the following first:
- ✔ Are all four feet firmly on the floor? If the machine wobbles when you press a corner, one foot is too short or too long.
- ✔ Have the transit bolts been removed? On a new machine, this is the classic cause of heavy vibration — they are located at the back and must be removed before the first use.
- ✔ Is the laundry distributed evenly? One heavy bathrobe on one side makes any machine bang; distribute the load in the drum or add a towel.
- ✔ Is the machine clear of the wall and cabinet? Contact with a wall transmits the vibration directly to the structure.
If everything is set up correctly and it still rumbles through the floor — especially with wooden subfloors and in apartments — an anti-vibration mat does what it was made for: it absorbs the vibrations before they enter the building and stops the machine from "walking" slowly across the floor. You will notice the effect most in the room below.
What a mat does and does not do
Honest expectation management: a mat dampens vibrations and prevents sliding. It does not correct unevenness, fix broken bearings, or undo an imbalance. If your machine continues to bang loudly during spinning after leveling and using a mat — especially with a metallic sound — that is a technical defect that a mechanic should look at, not an accessory problem.
Setting up a practical laundry room
Now that the machines are stacked, the floor underneath is free: the perfect spot for a laundry basket or a small rack. Three practical points: keep the hoses behind the machine free of kinks, leave the door ajar after washing so the drum dries and no musty odor develops, and if you dry laundry indoors — keep in mind that this is the heaviest source of moisture in the house. What that means for the indoor climate and how to prevent mold is explained in "Moisture in the house? Here's how to prevent mold".
Frequently asked questions
Can I place a dryer on top of a washing machine without a stacking kit?
Not recommended. The washing machine moves during the spin cycle, and without a connection, the dryer will gradually shift along with it — towards the edge. A stacking kit connects both machines into one unit and prevents this; many kits also feature a pull-out tray for the laundry basket.
Why does my washing machine vibrate so hard?
Usually due to unevenness, transit bolts not being removed on a new machine, or unevenly distributed laundry. Check those three first: level the machine using the leveling feet, remove the bolts, and distribute the load in the drum. If the rumbling persists, an anti-vibration mat will dampen the sound transmitted through the floor.
Does an anti-vibration mat really help with noise?
For transmitted noise, yes: the mat absorbs vibrations that would otherwise travel through the floor into the building — you will notice the difference most strongly in the room below and on wooden floors. However, the mat only dampens vibrations; it does not correct unevenness or fix technical defects.
Does a stacking kit fit every washing machine and dryer?
A universal stacking kit usually fits standard sizes just fine. For peace of mind, measure the width and depth of both machines before ordering — it takes two minutes and prevents the hassle of returning items.
