Short answer
Soft-mount washers use a suspension system to isolate more vibration and generally simplify installation. Hard-mount washers transfer more force to the structure and require a foundation designed for the selected machine. Confirm the manufacturer’s current installation drawing before construction.
Comparison
| Decision area | Soft-mount | Hard-mount |
|---|---|---|
| Vibration management | Machine suspension isolates more operating force. | Building foundation carries more operating force. |
| Site planning | Often easier for upper floors or retrofit projects, subject to structural review. | Usually needs a purpose-designed base or foundation. |
| Extraction | Often selected where higher extraction and lower residual moisture are priorities. | Performance depends on the model; compare current extraction data. |
| Initial installation | Can reduce foundation work, but utilities and anchoring still matter. | Foundation work must be included in project scope. |
How to choose
Ask the equipment supplier for operating weight, dynamic load information, anchoring details and service clearances. Then have the project’s qualified structural professional confirm the floor or foundation.
Questions for the site survey
- Is the laundry on ground level or an upper floor?
- What is the floor construction and condition?
- Can a foundation be built or modified?
- What extraction performance is needed for downstream drying?
- Are there adjacent spaces sensitive to vibration?
