How to Install PVC Shower Panels: A Step-by-Step Guide
One of the biggest advantages of PVC shower panels is how straightforward they are to install. Unlike tiles, which require specialist tools and professional skills, panels can be fitted by most competent DIYers in a single day — often in just a few hours.
What You'll Need
- PVC shower panels — measured to your wall area, plus 10% for cuts and waste
- PVC trims — internal corners, external corners, edge trims, and a starter trim
- Adhesive — a high-grab, waterproof panel adhesive (not general-purpose)
- Silicone sealant — clear or colour-matched, for sealing edges and joints
- Fine-tooth saw or sharp utility knife
- Tape measure, pencil, and spirit level
- Clean cloth and white spirit — for wiping away excess sealant
Step 1: Prepare Your Walls
Panels can be fixed to most flat, dry surfaces including plasterboard, plastered walls, and even existing tiles. The key is making sure the surface is clean, stable, and free from loose paint or flaking material.
If you're fitting over tiles, give them a thorough clean and make sure none are loose. If the wall is uneven, fix timber battens first and attach panels to those — this also creates an air gap for ventilation.
Step 2: Plan Your Layout
Measure each wall carefully. Most PVC shower panels come in standard widths of 250mm, 500mm, or 1000mm, and lengths of 2.4m or 2.6m. Work out how many panels you need, accounting for windows, taps, or shower fittings.
Start with the wall furthest from the door and work outward so any cut panels end up in the least visible position.
Step 3: Fit Your Starter Trim
Fix your starter trim to the edge of the wall where your first panel will sit. Use adhesive and small screws to hold it in place. Make sure it's perfectly vertical using a spirit level — this sets the alignment for everything else.
Step 4: Cut and Fit Your First Panel
Measure the wall height and cut your first panel to length. Apply adhesive to the back in a zigzag pattern. Slide the tongue edge into the starter trim and press firmly against the wall. Check it's level.
Step 5: Continue Across the Wall
Each subsequent panel slots into the previous one via the tongue-and-groove joint. Apply adhesive to each panel before fitting and press firmly. The interlocking system creates a tight, waterproof join. For the final panel, cut to width and fit an edge or corner trim.
Step 6: Cut Around Fixtures
For taps, shower valves, and pipes, mark the position and cut out using a hole saw or jigsaw. Cut slightly larger than the fitting to allow room for sealant, and finish with a pipe collar for a clean look.
Step 7: Seal All Edges
Run waterproof silicone sealant along the bottom edge where panels meet the bath or shower tray, around pipe holes, and along trim joins. This is the most important step for waterproofing. Smooth with a wet finger and wipe away excess before it sets.
Step 8: Final Check
Inspect every join, trim, and seal. Press any loose panels and top up sealant where needed. Allow 24 hours for adhesive to cure before using the shower.
Tips for a Professional Finish
- Always dry-fit panels before applying adhesive
- Cut panels face-down to avoid chipping the printed surface
- Use colour-matched trims for the cleanest look
- Don't skimp on sealant — it's your waterproof barrier
