What Size Bathroom Wall Panels Do I Need? A Complete Guide
Bathroom wall panels come in a wide range of widths — from 200mm narrow boards to 1000mm wide slab panels. Choosing the right width affects not just the look of your bathroom, but also the installation time, the number of joins visible, and the overall cost.
Width Options Available
| Width | Look | Best application |
|---|---|---|
| 200mm | Classic tongue-and-groove, beadboard style | Traditional, cottage, wainscoting |
| 250mm | Classic with slightly wider boards | Traditional-modern hybrid |
| 300mm | Transitional | Versatile — suits most styles |
| 500mm | Contemporary with subtle vertical lines | Modern bathrooms |
| 600mm | Near-seamless | Modern, minimal |
| 1000mm | Fully seamless, slab-like | Contemporary, luxury |
Which Width Looks Best?
For a traditional look — choose 200mm or 250mm. For a contemporary look — choose 600mm or 1000mm. Wide panels also make small bathrooms appear larger.
How to Calculate How Many Panels You Need
- Measure the height and width of each wall to be panelled
- Multiply height × width to get the m² for each wall
- Add all wall areas together for the total m²
- Add 10% for cuts and waste
