A washing machine in a closet saves space, but it can be noisy. Also read about the dos and don'ts of a washing machine in a closed closet . With the right setup, you can reduce both vibrations and airborne noise without compromising safety or ventilation. Below, you'll find a practical step-by-step plan that works in apartments, terraced houses, and detached houses.
Understanding Sound: Impact Sound vs. Airborne Sound
Vibrations from the washing machine will cause your floor and cabinet to vibrate. This is called impact noise and is often heard as thumping or resonance due to the structure. There is also airborne sound: the sound that radiates directly from the machine and through the cabinet doors into the room. For effective soundproofing, you address both. Impact noise can be reduced by adding mass and decoupling, for example, with a heavy platform and a vibration-dampening intermediate layer. Airborne noise can be reduced by adding absorption to the cabinet interior and by limiting gaps, while maintaining adequate ventilation. This combination prevents the sound from building up or traveling through the walls. To learn which materials, ventilation requirements, and stability are important, see the requirements for a washing machine cabinet .
Start with the subfloor: stable, heavy base
The biggest gains are achieved under the machine. A washing machine is naturally more stable on concrete than on wood. If your washing machine is on a wooden floor, create a separate, heavy platform that doesn't rest tightly against the walls or baseboards.
- Place a heavy plate (e.g. concrete or paving stone package) that is separate from the wall.
- For extra damping, create a mass spring: two heavy plates with a vibration-dampening mat between them. Make sure the whole thing is flat and stable.
- Check that all machine feet load the plate evenly and adjust them level.
- If the machine shakes violently or walks away, first resolve alignment and loading issues before adding additional cushioning.
On a concrete floor, a flat, heavy slab with a good rubber or PU mat underneath is often sufficient. The goal is always the same: to add mass and reduce contact with the building structure.

Insulating a washing machine in a cupboard: practical construction
In a washing machine cabinet, you want to prevent vibrations from traveling through the walls while simultaneously reducing airborne noise. Work in layers: decouple the machine from the floor, make the cabinet less reflective internally, and ensure proper ventilation.
- Place the washing machine on the heavy, detached platform. Leave a few millimeters of clearance all around and do not rigidly attach the machine to the cabinet.
- Cover the inside of the back and side walls with acoustically absorbent material. Choose a sufficiently thick, fire-resistant panel and install it vibration-free.
- Minimize gaps in cabinet doors with draft excluders, but avoid completely sealing them. A slightly heavier door will help block airborne noise.
- Where possible, use a pull-out tray or stable shelf that does not resonate hollowly; add mass if necessary.

Ventilation and safety
Always ventilate: leave openings at the top and bottom of the cabinet unobstructed, especially with a heat pump or condenser dryer. Maintain 3-5 cm of clearance around the appliance; you can read more about the correct distance behind the washing machine in the cabinet here. Prevent heat buildup and install a leak protection device where necessary. Pay attention to the load-bearing capacity of the installation and secure high-mounted machines to prevent tipping. Always follow the installation instructions for your cabinet. At Wasdroom, you'll find sturdy , closed washing machine cabinets and clear instructions; the final soundproofing depends on your own installation and material choices.
Common mistakes that actually make more noise
- A thin layer of foam under the machine without extra bulk - this provides cushioning, but does not dampen.
- Placing the machine or platform tightly against walls actually feedback vibrations.
- Insufficient ventilation in a fully closed cabinet – more heat, more resonance and risk of malfunctions.
- Using vibrating feet on an unstable machine - first adjust the alignment, transport bolts and loading.
Frequently Asked Questions
How can I reduce the noise of my washing machine?
Start with a flat, heavy, and freestanding base. Add a vibration-dampening layer between two heavy plates and adjust the machine feet to a perfectly level level. Reduce airborne noise with absorbent material in the cabinet and heavier doors, while maintaining ventilation.
Can you put a washing machine in a wardrobe?
Yes, provided the cabinet can handle the weight, you maintain adequate ventilation and clearance, and the connections are secure. Use a freestanding, heavy platform, don't rigidly connect the machine to the cabinet, and secure any high-rise installation to prevent tipping.
How do you soundproof a washing machine cabinet?
Completely soundproofing is unrealistic. Aim for soundproofing: adding mass, decoupling from the floor, and absorbing the interior. Limit gaps with moldings and choose heavier doors, but maintain airflow for cooling and moisture removal.
