Using 3D Scanning for Bathroom and Kitchen Refits
3D laser scanning is increasingly used for UK bathroom and kitchen refits to capture millimetre-accurate as-built measurements, eliminating the measurement errors that cause costly rework during tile fitting and cabinet installation. Traditional tape measures cannot capture the subtle imperfections in old walls — the slight out-of-square corners, uneven floors, and hidden pipes — that make the difference between a perfect fit and expensive callbacks.
This guide explains how 3D scanning works for bathroom and kitchen refurbishments, the accuracy achieved, what deliverables you receive, and typical costs in 2025.
How 3D Laser Scanning Works for Refits
| Step | Process | | --- | --- | | 1. On-site scan | Surveyor positions a terrestrial laser scanner (e.g., Leica RTC360, FARO) in multiple positions to capture the entire room — typically 3–6 scan positions for a standard bathroom | | 2. Data capture | Scanner emits laser pulses measuring 1 million points per second, recording distances to walls, floors, ceilings, pipes, sockets, and fixtures | | 3. Point cloud creation | Individual scans are registered and stitched together into a unified 3D point cloud (.e57/.rcs/.las format) with up to ±1–2mm accuracy | | 4. Processing | Point cloud is imported into CAD or Revit software to produce 2D drawings, 3D models, or BIM deliverables |
For bathrooms and kitchens, the scanner captures every detail including sanitaryware positions, pipe and drain locations, window reveals, ceiling heights, and any existing damage or irregularities.
Why Traditional Measuring Fails for Refits
| Problem with Tape Measures | Consequence | | --- | --- | | Out-of-square corners | Tiles cut to wrong angles — visible gaps at corners | | Uneven floors | Cabinet plinths leave visible gaps — worktop doesn't sit level | | Undocumented pipe positions | Drilling hits pipes — cost of repair and delay | | Hidden obstacles | Socket positions, recessed cabinets, stud walls — missed measurements | | Single-point measurements | Missing the bow in a wall — worktop has a gap | | Ceiling height variation | False ceiling panels or bulkheads not accounted for |
A 3D scan captures all of this in one visit — and the point cloud is available for re-measurement if the scope changes.
Accuracy for Tile Fitting and Cabinet Installation
| Application | Accuracy Achieved | Benefit | | --- | --- | --- | | Tile layout | ±1–2mm | Captures wall out-of-square, uneven floors, and corner irregularities for perfect cut tiles | | Cabinet installation | ±1–2mm | Exact measurements for bespoke units — identifies pipe and obstacle locations before fabrication | | Worktop templating | ±1mm | Eliminates need for return visits — digital template sent directly to stone or composite fabricator |
Important: A bad scan can have up to 30mm error due to poor registration and setup. Professional survey companies achieve ±2mm consistently through proper control setup and multiple scan positions.
What 3D Scanning Captures for Refits
| What Is Measured | Why It Matters for Refits | | --- | --- | | Wall dimensions and angles | Exact tile layout — no mis-cuts at corners | | Floor levels and flatness | Cabinet plinths and flooring installation | | Ceiling heights and bulkheads | Fitting bathroom pods, false ceilings, extractor fans | | Window and door positions | Tiling around reveals, cabinet placement | | Sanitaryware positions | Exact locations of toilet, basin, bath, shower for new installations | | Pipe and drain positions | Prevents drilling into hidden services | | Electric socket and switch positions | Avoids clashes with new cabinetry | | Light fitting positions | Ceiling void access and light fixture relocation | | Wall bow and deflection | Worktop and tile fitting tolerances |
Point Cloud for Kitchen Design
The point cloud serves as a digital twin of your existing space — enabling kitchen designers to work from accurate measurements without site visits.
| Use | How It Helps | | --- | --- | | Import into Revit, AutoCAD, or SketchUp | Kitchen designers work from the accurate as-built model | | Visualise cabinetry, appliances, and plumbing | Check layout and clearance before ordering | | Clash detection | Identify pipe and cable conflicts before demolition | | Plan complex tile patterns | See exact wall and floor junctions for precise layout | | Worktop templating | Digital template sent directly to stone or composite fabricator | | Future reference | Point cloud archived for any future changes |
Worktop Templating from Point Cloud
For stone or composite worktops (granite, quartz, solid surface), the point cloud enables digital templating:
- Scan the kitchen after cabinets are installed and levelled
- Point cloud imported into CAD software
- Digital template generated with exact cut-outs for hobs, sinks, and tap holes
- Template data sent directly to the stone fabricator
- No return visit needed — accuracy of ±1mm without the templater on site
This is particularly valuable for island kitchens, L-shaped layouts, or properties where access is difficult.
Deliverables for Bathroom and Kitchen Refits

2025 Costs in the UK
| Deliverable | Price Range (ex VAT) | | --- | --- | | Point cloud only | £750–£1,250 per day | | Single bathroom or kitchen scan | £800–£2,500 for small residential | | Point cloud plus 2D CAD drawings | £1,000–£2,000 per room | | Point cloud plus 3D Revit or BIM model | £1,500–£5,000+ depending on complexity | | Hourly rate (scanning only) | £100–£500 per hour | | Worktop digital template | £300–£800 |
Cost factors:
- Size and complexity of the space (historic buildings add 15–30%)
- Deliverables required (BIM modelling is most expensive)
- Site challenges — night work (+20%), scaffolding (+15%)
- Number of scan positions required
When to Commission a Scan for Your Refit
| Project Type | Should You Scan? | | --- | --- | | Bespoke fitted kitchen | Yes — essential for accurate cabinetry and worktop fabrication | | High-end bathroom with stone tiles | Yes — tile layout accuracy is critical | | Period property with uneven walls | Yes — captures the irregularities that standard measuring misses | | Boutique hotel bathrooms | Yes — consistency across multiple rooms | | Standard replacement suite | Possibly — may not justify the cost for simple replacements | | Property with no prior drawings | Yes — creates the first accurate record of the space |
Frequently Asked Questions
Q: Can 3D scanning replace a site visit by the kitchen designer?
A scan provides accurate measurements, but most kitchen designers also need to see the space in person to assess finish quality, light, and spatial feel. Use the scan as the measurement tool and supplement with a designer's site visit for the creative aspects.
Q: How long does a bathroom or kitchen scan take?
For a standard bathroom: 30–60 minutes on site, with deliverables (drawings and point cloud) available within 3–5 working days. For a standard kitchen: 1–2 hours on site, with deliverables within 5–7 working days.
Q: Do I need to empty the room before scanning?
The scanner can work around furniture, but better results are achieved with clear access to walls and floors. Ideally, remove large items from the bathroom or kitchen before the scan. The surveyor can advise on the day.
Q: Can the scan show existing pipe and cable positions?
Yes — the laser scan captures the surface geometry of all visible pipes, conduits, and service routes. Hidden services (within walls, under floors) cannot be captured without additional investigation such as ground-penetrating radar or reference to as-built drawings.
Q: Is 3D scanning worth it for a simple bathroom replacement?
For a straightforward like-for-like replacement (new toilet, basin, bath, tiles), a traditional measured survey may be sufficient. For bespoke fitted furniture, stone worktops, complex tile patterns, or period properties with uneven walls, a 3D scan pays for itself in avoiding mis-cuts and re-makes.
Q: Can the point cloud be used for future projects?
Yes — the point cloud is a permanent archive of the space at the time of survey. It can be re-measured for future alterations without returning to site, which is particularly valuable for rental properties or homes where you anticipate future changes.
Q: What is digital worktop templating?
Digital worktop templating uses the point cloud data to generate a precise measurement file — DXF or PDF — that is sent directly to the stone or composite worktop fabricator. The fabricator cuts the worktop to exact dimensions without a physical site visit. This saves time and is increasingly standard for high-end installations.
