Wall Panelling Cost Calculator: Budget Your Project

Wall panelling costs £15–45 per m² for materials, depending on the panel type and finish — with a total fitted cost of £25–70 per m² including trims, adhesive, and labour. A standard bathroom (approximately 12 m² of wall area) costs £300–850 fully panelled, making it 40–60% cheaper than a tiled equivalent. Costs vary by panel quality, finish type (smooth vs embossed), colour range, and whether you fit the panels yourself or hire a professional.

Budgeting a wall panelling project accurately requires more than just multiplying the panel price by the wall area. You need to account for trims, adhesive, sealant, waste allowance, and (if applicable) labour. This guide breaks down every cost element so you can budget your project with confidence.

How to Calculate Your Project

Step 1: Measure the Walls

Measure each wall separately:

  • Height: Floor to ceiling (or floor to desired panel height if not full-height)
  • Width: Wall to wall

Calculate the area of each wall: Height × Width = m²

Subtract large openings: Windows, doors, and any areas not being panelled. Subtract at least 50% of these areas from your total (you will still need some material for the panels around the edges of openings).

Step 2: Add Waste Allowance

Add 10% to your total m² figure. This covers:

  • Cutting waste (offcuts from panels cut to fit around pipes, windows, corners)
  • Measurement errors
  • Damaged panels (rare, but allows for one mistake)

Step 3: Calculate Panel Quantities

Divide your total m² (including waste) by the coverage per panel:

  • A standard panel (250 mm × 2,700 mm) covers approximately 0.675 m²
  • A wider panel (333 mm × 2,700 mm) covers approximately 0.9 m²
  • Round up to whole panels

Step 4: Count Trims

Trim TypeWhereHow Many
Internal cornerEvery internal cornerCount corners (typically 4 per room)
External cornerWindow reveals, boxingCount external corners
Start/end trimFirst panel edge, last panel edge2 per wall (or use corners)
Ceiling trim / covingTop of panelsTotal perimeter of room
Base trim (optional)Bottom of panelsTotal perimeter (often sealant is used instead)

Step 5: Adhesive and Sealant

  • Adhesive: 1 tube per 3–4 m² of panels (varies by adhesive brand)
  • Silicone sealant: 1 tube per 6–8 metres of junction (bath edge, shower tray, edges)

Cost-Saving Tips

1. DIY Installation

Labour is 30–50% of the total fitted cost. Wall panel installation is genuinely achievable as a DIY project with basic tools — no tiling skills, no specialist equipment, and the process is straightforward enough for a confident homeowner to complete in a day. See our installation guide for step-by-step instructions.

2. Buy in Bulk

If panelling multiple rooms or properties (landlords, developers), buying panels by the pallet significantly reduces the per-panel cost. Speak to your supplier about volume pricing.

3. Choose Standard Colours

Popular colours are stocked in volume and priced lower. Specialist colours and premium finishes command higher prices and may have longer lead times.

4. Standard Panel Sizes

If your ceiling height matches standard panel lengths (2,400 mm or 2,700 mm), you avoid cutting waste. Measure before ordering — many bathrooms have ceilings at or near these heights.

5. Use the Kalsi Calculator

Our wall panelling calculator takes your room dimensions and calculates the exact number of panels, trims, and adhesive you need — preventing over-ordering.


Panels vs Tiles: Cost Comparison

For a standard 12 m² bathroom:

Cost ElementWall PanelsCeramic Tiles
Materials£185–640£415–1,740
Labour£0–500£400–1,500
Ongoing maintenance (5-year)£0£150–400 (regrouting)
5-year total cost£185–1,140£965–3,640

Panels save 40–70% over a 5-year period when maintenance costs are included.


Frequently Asked Questions

How much does wall panelling cost?

£15–45 per m² for materials, depending on the panel type and finish. A standard bathroom (12 m²) costs £185–640 for materials or £385–1,140 fitted. This is 40–60% cheaper than a tiled equivalent.

How much wall panelling do I need?

Measure each wall (height × width) to get the total m². Add 10% for waste. Divide by the coverage per panel to get the number of panels. Use our wall panelling calculator for an exact figure.

Is it cheaper to panel or tile a bathroom?

Panelling is significantly cheaper. A fully panelled bathroom costs £185–1,140 (materials to fitted). A tiled equivalent costs £815–3,240. Panels also have lower maintenance costs over their lifespan.

How much does a professional installer charge?

Typically £25–60 per hour, with a standard bathroom taking 4–8 hours. Total labour cost: £200–500. Some installers quote per room rather than per hour — get at least two quotes for comparison.

Can I save money by fitting panels myself?

Yes — DIY saves £200–500 on a standard bathroom. Wall panel installation requires basic DIY tools and skills. The process is significantly simpler than tiling and does not require specialist equipment. Most homeowners can complete a standard bathroom in 4–8 hours, and the room is ready to use as soon as the sealant has cured (typically 24 hours, though the bathroom can be used carefully before this).
