How to Calculate Materials for a Kitchen Renovation
A kitchen renovation can range from a quick backsplash and paint refresh to a complete refit. Our calculator helps you estimate materials for the three most common DIY kitchen projects: backsplash tiling, cabinet painting, and countertop replacement.
Kitchen Renovation Cost by Element
| Element | Budget | Mid-Range | Premium |
|---|---|---|---|
| Backsplash tiles (1.8 sqm) | EUR 40-70 | EUR 70-130 | EUR 130-250 |
| Tile adhesive + grout | EUR 15-25 | EUR 20-35 | EUR 25-45 |
| Cabinet paint (12 doors) | EUR 40-80 | EUR 80-150 | EUR 150-250 |
| Primer (12 doors) | EUR 15-30 | EUR 25-45 | EUR 40-60 |
| Laminate countertop (3m) | EUR 240 | EUR 360 | EUR 480 |
| Stone countertop (3m) | - | EUR 600 | EUR 900-1500 |
| Materials subtotal | EUR 350-485 | EUR 755-1120 | EUR 1045-2585 |
Labour for a full kitchen refresh (backsplash + paint + worktop) typically costs EUR 800-2000 depending on kitchen size and location.
Common Kitchen Layouts and Sizes
| Layout | Typical Length | Floor Area | Best For |
|---|---|---|---|
| Galley (two parallel runs) | 2.5-4 m | 6-10 sqm | Narrow rooms, apartments |
| L-shape | 3-4 m + 2-3 m | 8-14 sqm | Most homes, good workflow |
| U-shape | 3 runs of 2-3 m | 10-16 sqm | Larger kitchens, maximum storage |
| Island | L or U + 1.5-2 m island | 14-20 sqm | Open-plan, social cooking |
| Single wall | 3-5 m | 6-12 sqm | Studios, open-plan living |
The work triangle (fridge-sink-hob) should total 4-8 metres for efficient movement. Our calculator uses the floor area to estimate project duration — smaller kitchens under 8 sqm take 3-5 days, medium kitchens 5-8 days, and large kitchens 8-14 days.
Backsplash Tile Materials
| Material | Cost per sqm | Pros | Cons |
|---|---|---|---|
| Ceramic (10x10cm) | EUR 20-35 | Affordable, easy to cut, huge colour range | Can chip on edges |
| Glass mosaic | EUR 40-80 | Reflective, waterproof, modern look | Expensive, shows imperfections |
| Subway tiles (10x20cm) | EUR 25-45 | Timeless, versatile, easy to lay | Requires more grout than large tiles |
| Porcelain (30x60cm) | EUR 30-60 | Durable, minimal grout lines | Heavy, needs diamond blade for cuts |
| Natural stone | EUR 50-100 | Unique patterns, premium look | Needs sealing, porous |
Cabinet Painting Coverage
One litre of cabinet paint covers approximately 10 sqm. Each cabinet door is approximately 0.5 sqm. With 2 coats of paint and 1 coat of primer:
- 10 doors: 1 L paint + 0.5 L primer
- 15 doors: 1.5 L paint + 0.8 L primer
- 20 doors: 2 L paint + 1 L primer
- 25 doors: 2.5 L paint + 1.3 L primer
Always degrease, sand, and prime before painting. Melamine cabinet paint adheres to glossy surfaces without heavy sanding. Allow 16-24 hours between coats for a hard, durable finish.
If you are renovating the bathroom at the same time, our bathroom renovation calculator provides tile and waterproofing estimates. For repainting other rooms, try the paint calculator. The tile calculator handles general tiling projects beyond the kitchen backsplash.
These calculations are estimates only. Actual requirements may vary depending on surface conditions, product specifications, and installation methods. Always consult a qualified professional for precise measurements.
