Why Choose Bathroom Wall Panels Over Tiles?

Bathroom wall panels are a stylish, low-maintenance alternative to traditional tiles:

100% waterproof when installed correctly with trims and sealant
Quick to fit with minimal preparation
Easy to clean with no grout lines to scrub
Wide range of finishes to suit any bathroom style

Tiles vs. PVC Panels – Which Should You Choose?

Bathroom Panel Sizes & Best Uses

We offer two main thicknesses and sizes of PVC panels for bathrooms:

10mm Thick Shower Panels

Size: 1m width × 2.4m height
Best for: High-moisture areas like shower enclosures and wet zones
Benefits: Large coverage per panel, fewer joins, more rigid and durable

8mm Thick Bathroom Wall Panels

Size: 250mm wide × 2600mm high (supplied in packs of 4 = 1m wide × 2.6m high total coverage)
Best for: General bathroom walls, utility rooms, and lower-moisture areas
Note: Not recommended for showers or areas with constant water exposure

👉 Choosing your panel size before measuring will make your calculations more accurate.

Tools You’ll Need to Measure

5m+ steel measuring tape (for accuracy)
Pencil and notepad (or phone)
Spirit level (to check for wall straightness)
Stepladder (for high walls)
Masking tape (optional, to mark panel coverage)

Step-by-Step: How to Measure Bathroom Walls

1. Measure Each Wall Separately

Measure from one corner to the other at floor level, mid-wall, and near the ceiling.
Record the smallest measurement to ensure the panels fit without forcing.
Repeat for every wall — bathrooms often have slight variations or irregular shapes.

2. Measure Wall Height

Measure from the finished floor to the ceiling.
If installing above a bath or shower tray, measure from the tray/bath edge to the ceiling.
Panels can be trimmed down, but exact measurements help you plan cuts more accurately.

3. Record Obstacles and Fixtures

Mark and measure the position of:
- Windows and alcoves
- Pipes, taps, shower valves, niches
- Doors (if panelling above them)
- Extractor fans, switches, or sockets

Easy Panels’ Top Measuring Tips

Measure after removing old tiles/panels — wall dimensions can change
Plan joins so they’re in discreet areas, not mid-window or mid-feature
Check ceiling height in several spots (especially in older homes)
Don’t forget trims and silicone sealant for a watertight finish

How to Calculate How Many Panels You Need

For 10mm Shower Panels (1m wide × 2.4m high):

Add up the total wall width you want to cover.
Divide by 1 metre (the panel width).
Round up to the nearest whole panel.

Example:

Wall width = 3.4m
3.4 ÷ 1 = 3.4 → 4 panels needed

For 8mm Wall Panels (250mm wide × 2600mm high, packs of 4):

Add up the total wall width you want to cover.
Divide by 0.25 metres (the width of a single panel).
Round up to the nearest whole panel.

Single Wall Example:

Wall width = 2.5m
2.5 ÷ 0.25 = 10 panels needed

Multiple Wall Example:

Wall 1 = 2.5m , Wall 2 = 2.5m → total width = 5m
5 ÷ 0.25 = 20 panels needed

✅ Always calculate each wall separately, then add them together for your total. This avoids underestimating if walls vary in width or height.

Should You Order Extra?

Yes. Always order 10% more than your calculation. This covers cuts, mistakes, and pattern matching — avoiding costly delays if you run short.

DIY vs Professional Installation

DIY-friendly: Bathroom panels are generally easier to fit than tiles, making them ideal for competent DIYers.
Professional recommended: For shower enclosures and high-moisture zones, professional fitting ensures perfect waterproofing and longevity.
