Learn how to Measure Bathroom Wall Panels for a Perfect Fit, with our Simple Step-by-Step Guide for Shower Panels.
If you want your panel installation to go smoothly, you need to measure your wall accurately from the start.
Donβt worry, weβll show you exactly how to do it.
This simple step by step guide shows you how to measure your bathroom wall, work out how many panels you need, and avoid costly mistakes.
Follow this and your PVC wall panelling will sit properly, your shower panels will line up clean, and you will get a perfect fit without stress.
What tools do you need to measure your walls for panel installation?
Youβll need a tape measure, a notebook and pen. These are the minimum tools to ensure accurate measurements.
A spirit level is optional but helps check alignment and ensures the wall is perfectly level before you begin.
Using the right tools reduces the risk of errors and helps ensure all panels are ready for installation.
Step by step guide to measure your wall panels
1. Measure the width of a wall
Use a tape measure and measure from one corner of the wall to the other in a straight line. Keep the tape level and tight so you get an accurate measurement. Write the number down straight away so you can record all measurements clearly and avoid confusion.
2. Check the wall measurement in three places
Measure the same wall at the bottom, middle, and top. Walls are often uneven, so each measurement may differ slightly. Use the largest measurement to ensure your panel will cover the full width without leaving a gap. This step ensures all panels will fit properly across the wall.
3. Measure the height of the wall
Measure from the floor to the ceiling. If you are installing shower panels, measure from the top of the shower tray or bath instead. Make sure the tape runs straight so your measurement is precise and consistent. This gives you the correct height needed for a precise fit.
4. Measure each wall separately
Measure every wall separately, even if they look the same size. Write each wallβs measurements down clearly so you donβt mix them up. Measuring each wall individually helps you calculate the number of panels required and keeps your layout organised.
Top Tip: Draw your bathroom from above and write the measurements on the sketch. It makes the layout clear, avoids mix ups, and helps you plan your panels properly.
5. Work out how many panels you need
Each panel covers 1 metre in width. Take your wall measurement and round up to the next full number. Example: If your wall is 3.7 metres wide, you will need 4 panels. This ensures full coverage across the wall.
6. Add extra panels for cuts and adjustment
Add around 10% extra panels to your total. This allows for cuts, trimming, and small mistakes during installation. It also helps if your wall is uneven and needs slight adjustment to ensure all panels fit neatly.

Frequently Asked Questions
What are the common sizes of bathroom wall panels and how do I calculate how many I need?
Most standard bathroom wall panels measure about 2400mm long x 1000mm wide. Decorative and tile-effect panels also come in other panel sizes (for example, 250mm or 600mm widths). To find how many panels you need, measure the width of your wall in millimetres (or centimetres) and divide that length by the panel width. Then round up to the nearest whole panel. For example, a 3700mm wide wall Γ· 1000mm panel width = 3.7, so you would need 4 panels.
How do I measure my walls accurately for panel installation?
Use a tape measure to get precise measurements. Measure each wall separately by stretching the tape from one corner to the other, keeping it level and straight. Note the width and height in millimetres (mm). It's best to measure in at least three places, bottom, middle, and top, and use the largest width. Record each measurement carefully in your notebook to ensure you have correct measurements for installation.
How should I measure around wet walls or shower areas?
For shower panels or wet walls, measure from the top of the shower tray or bath to the ceiling for height, and measure corner to corner for width as usual. Make sure to account for any fixtures like taps or soap holders. These panels are designed for wet areas, so measuring the same way as other walls will give you the correct height and width needed.
Can I install wall panels as a DIY project and how precise do the measurements need to be?
Absolutely, fitting bathroom wall panels is DIY-friendly. However, precise measurements are crucial. Take your time with each measurement in mm or cm and double-check them. Record each dimension and plan your layout ahead. Proper preparation and accurate measuring will help ensure a professional, seamless finish.
Why should I buy extra panels when installing, and how do I handle cutting and trims?
It's wise to add about 10% extra panels to your order to account for cuts, mistakes, and future repairs. Bathroom walls are often uneven, so extra panels ensure you can adjust as needed. Also, plan your layout so that trims and decorative edges align neatly. Wall panels also come in decorative finishes, like tile or marble effect, so allow for patterns when cutting. Having extra panels means you can cut carefully and still have backup panels if needed.
Where can I find more help with panel measurements?
If you're unsure, sketch your bathroom layout from a bird's eye view and add the wall dimensions to each side. This visual plan makes it easy to see each wall's size. Remember the rule: measure twice, cut once. If you still need advice, feel free to call our team or visit our contact page.
