EWI Design
EWI Design is a trusted home improvement consultancy based in Belvedere, Kent, specialising in high-quality bathroom and kitchen design, bespoke carpentry, luxury flooring, and full-home renovation services. Serving homeowners across London and Kent—including Bexleyheath, Sidcup, Eltham, Blackheath, and Plumstead—EWI Design blends creativity with craftsmanship to transform everyday spaces into stylish, functional interiors. With a hands-on approach and meticulous attention to detail, the team brings your vision to life—on time, on budget, and with stunning results.
Transform Your Dartford Bathroom Into A Luxury Sanctuary
Your bathroom renovation deserves better than the “measure-supply-rush installation-disappear” approach dominating Kent’s home improvement industry. We’ve seen the aftermath: beautiful Scudo suites installed over inadequately waterproofed walls, premium Aqualisa showers losing pressure within months, expensive RAK Ceramics tiles cracking because contractors skipped substrate preparation.
The bathroom fitting industry in Dartford is plagued by cowboys charging premium prices for amateur work. Homeowners discover mistakes 6-18 months later when mould appears, leaks develop, or tiles lift. By then, the “contractor” has vanished.
At EWI Design, we’ve spent over a decade perfecting bathroom installations across Dartford, Bexleyheath, and Kent. We’re not general builders who “also do bathrooms” – we specialise in complete renovations from design through final grouting. Every installation includes comprehensive waterproofing, professional plumbing, meticulous tiling, and a 2-year workmanship guarantee.

Dartford Property Expertise
Dartford’s housing stock spans Victorian terraces through 1930s semis to modern new-builds. Each era presents unique challenges we’ve mastered across 400+ Kent bathroom installations:
Victorian & Edwardian (pre-1919): Solid walls requiring specialist waterproofing, cast iron pipework needing replacement, limited floor depth restricting waste routing, lime plaster incompatible with standard adhesives.
Inter-war (1920s-1940s): Asbestos materials requiring safe removal, lead pipework replacement, solid floors with rising damp, and structural assessment needs.
Post-war (1950s-1970s): Concrete construction challenges, outdated soil stacks, undersized hot water cylinders, and electrical upgrades required.
Modern (1980s+): Plasterboard walls requiring reinforcement, plastic waste systems prone to poor installation, and Building Regulations ventilation compliance.
That experience means fewer surprises, faster problem-solving, and installations lasting decades.
Our Complete Bathroom Installation Process
Stage 1: Free Design Consultation & Survey
Before purchasing anything, we visit your Dartford property for a comprehensive assessment:
Structural evaluation: Floor load capacity, wall construction, ceiling considerations, window positioning, ventilation requirements.
Plumbing assessment: Water pressure and flow rate, boiler capacity, existing pipework condition, waste pipe routing, and soil stack location.
Electrical assessment: Consumer unit adequacy, IP rating zones, extractor fan options, and underfloor heating feasibility.
Design planning: 3D visualisation, material selection from supplier ranges, fixture positioning, storage solutions, and budget optimisation.
No obligation. No pressure. Just honest expertise from bathroom specialists who’ve seen every challenge Dartford properties present.
Call 01322 933 677 to schedule.
Stage 2: Detailed Quotation & Material Selection
We provide a comprehensive written quotation within 48 hours, including a complete materials schedule, labour breakdown by trade, removal and disposal costs, waterproofing and substrate preparation, fixtures and fittings, waste removal, and a 2-year guarantee.
Material selection assistance: Showroom visit to our Belvedere location, or we can bring samples to your property. Scudo bathroom suites, Aqualisa shower options, RAK Ceramics tile selection (200+ options), Grohe and Crosswater taps, lighting and accessories.
Stage 3: Installation (8-12 Days Standard Bathroom)
Days 1-3: Removal & First Fix
- Existing bathroom removal and responsible disposal
- Old pipework replaced with new copper or PEX systems

Common Bathroom Renovation Challenges in Dartford Properties
| Property Type | Common Challenge | Why It’s a Problem | Professional Solution |
|---|---|---|---|
| Victorian & Edwardian Homes | Limited floor depth | Modern waste pipes require 40-50mm fall per metre, which original floors often can’t accommodate | Strategic pipe routing, macerator pumps where appropriate, or discreet floor raising with smooth transitions |
| Victorian & Edwardian Homes | Solid walls retaining moisture | Traditional brick walls trap moisture, leading to damp, mould, and tile failure | Specialist tanking systems, breathable materials, enhanced ventilation, and moisture-resistant substrates |
| Victorian & Edwardian Homes | Cast iron pipework | Corroded, undersized soil stacks restrict flow and risk leaks | Careful removal and replacement with modern plastic systems using correct transition adaptors |
| 1930s-1950s Properties | Asbestos-containing materials | Ceiling tiles, floor tiles, and pipe lagging may contain asbestos, posing serious health risks | Pre-work testing, licensed asbestos removal if required, and compliant safe disposal |
| 1930s-1950s Properties | Inadequate ventilation | Original bathrooms rarely included mechanical extraction, leading to condensation and mould | Installation of compliant extractor fans meeting current Building Regulations |
| Modern Properties (1980s+) | Plasterboard walls not tile-rated | Standard 12.5mm plasterboard cannot safely support heavy tiles | Moisture-resistant board upgrades, tile backer boards, or full aqua-board systems |
| Modern Properties (1980s+) | Poorly installed plastic waste systems | Push-fit connections leak; undersized pipes cause slow drainage | Complete waste system replacement using correctly sized, solvent-welded pipework |
| Modern Properties (1980s+) | Low water pressure | Combi boilers and weak mains pressure reduce shower performance | Pressure testing, pump installation where viable, or alternative shower system specification |
Why Professional Installation Outperforms DIY
Common DIY disasters we remediate:
- Inadequate waterproofing (42% of failures) – Cost of fixing: £3,000-6,000. Water penetrates walls, causing mould, rot, structural damage, and ceiling damage in rooms below.
- Incorrect plumbing (28% of failures) – Cost of fixing: £1,500-4,000. Inadequate waste pipe falls, causing blockages, leaking connections, damaging subfloors, and shower pressure issues from undersized pipework.
- Electrical safety violations (18% of failures) – Cost of fixing: £800-2,000. Fixtures in wrong IP zones, missing RCD protection, inadequate bonding, and failed Building Control inspections.
- Tile installation failures (12% of failures) – Cost of fixing: £2,000-5,000. Cracking due to inadequate substrate preparation, lippage (uneven edges), and poor waterproofing, causing mould.
Time investment reality:
- Experienced DIYer: 60-100 hours over 4-6 weeks
- Professional team: 8-12 days start to finish
- Quality difference: Immediately obvious; failures apparent within 6-24 months
Cost comparison:
- DIY materials + tool hire: £3,000-5,000
- DIY remediation after failures: £2,000-8,000 additional
- Professional installation: £5,000-12,000 (guaranteed work, no remediation)
The question isn’t whether you can install a bathroom yourself-it’s whether you want to risk £5,000-13,000 on your first attempt with no guarantee, no comeback, and potential insurance implications.
Building Regulations & Legal Requirements
All bathroom renovations in Dartford must comply with Building Regulations. Non-compliance causes issues selling your property, insurance claims, and potential prosecution.
Key regulations applicable to bathrooms:
Part C – Waterproofing, damp-proofing, moisture resistance
Part G – Drainage, water supply, sanitary accommodation, water efficiency
Part H – Drainage systems, proper falls, soil stack ventilation
Part L – Insulation if external walls/windows are altered, energy-efficient lighting
Part P – All electrical work requires a Part P-certified electrician or Building Control notification
EWI Design handles all compliance: Notification to Dartford Building Control, coordination of inspections, provision of completion certificates, and electrical and plumbing testing certificates.
Learn more: Planning Portal – Building Regulations provides comprehensive guidance.
Industry Resources & Standards
Chartered Institute of Plumbing and Heating Engineering (CIPHE) – The professional body for plumbing and heating engineers provides technical standards, continuing professional development, and best practice guidance.
British Standards: BS 6465 (sanitary installations), BS 8000-13 (ceramic tiling workmanship), BS 5385 (wall and floor tiling), BS EN 1451 (plastic piping systems).
At EWI Design, we exceed British Standards requirements-they represent minimum acceptable practice, not best practice.
