How much does a bathroom cost in Blackheath?
Across Blackheath and nearby areas — Blackheath Village, Blackheath Standard, Westcombe Park, Cator Park and the Kidbrooke side — typical 2025 ranges are:
| Scope | Typical Total Range* | Best For | What’s Usually Included |
|---|---|---|---|
| Essentials Refresh | £6,000–£8,000 | Like-for-like swap with cleaner, smarter finishes | Suite replacement, minor plumbing tweaks, partial tiling, silicone, making good |
| Complete Refurb (Most Popular) | £8,000–£12,000 | Full strip-out and modernisation | Re-boarding where needed, tanking in wet zones, full tiling, upgraded lighting, furniture install, waste removal |
| Premium Wet Room / High-End | £12,000–£20,000+ | Layout change or top-spec finish | Walk-in / former & linear drain, full tanking, UFH, niches, premium brassware, feature lighting |
*Ranges include typical labour, preparation, materials and waste. Final quotes vary with room size, tile area, plumbing/electrical changes and specification.
What pushes costs up (or down)
- Layout changes (moving a WC, shower or stack).
- Tile format & pattern (mosaics, herringbone = more labour; large-format = fewer grout lines, more handling care).
- Electrics (downlights, mirror demisters, fans, shaver sockets, zone/IP compliance).
- Substrate & prep (levelling, cement boards, waterproofing/tanking).
- Specification (brassware grade, screens, furniture, stone tops).
Buildaway tip: Keep the layout stable to save on plumbing and electrics, then invest in better waterproofing and brassware — the finish and longevity are night-and-day.
Timeline: how long will it take?
- Essentials Refresh: 7–10 days
- Complete Refurb: 10–14 days
- Premium / Wet Room / Layout change: 14–20+ days
Drying times, tile format, electrics and any re-boarding/tanking affect duration. We phase works to minimise downtime and keep your household running.
Do I need planning permission or building regulations?
- Planning permission: Not usually for internal works (exceptions: listed buildings, or if part of an extension). Blackheath includes conservation areas and period homes, so we’ll flag any constraints early.
- Building regulations:
- Electrics: Bathrooms are a “special location” — works must comply with Part P (zoning/IP ratings, certification).
- Ventilation: Adequate extraction is required; we’ll advise on fan spec and ducting.
- Drainage/structure: Significant drainage alterations or structural changes may require approval.
You’ll receive the appropriate certificates on completion.
Price breakdown (where the budget goes)
- Labour: ~55–65% (plumbing, tiling, carpentry, plastering, electrics)
- Materials & consumables: ~30–40% (suite, boards, adhesives, trims, grout, fixtures)
- Waste & sundries: ~5–10%
Blackheath bathroom choices we’re fitting most right now
- Walk-in showers with tiled formers and linear drains
- Large-format porcelain for a clean, minimal grout look
- Underfloor heating paired with IP-rated downlights and mirror demisters
- Wall-hung furniture and built-in niches for storage and space
- Matt black or brushed brass brassware for a modern, timeless style
Local insight: Many Blackheath homes are Victorian/Edwardian terraces, Georgian villas and mansion flats near the Heath; smart storage, wall-hung furniture and light-reflecting tiles make a big difference in narrower rooms.
How to choose the right bathroom fitter (and avoid the headaches)
- End-to-end capability: One accountable team for plumbing, tiling, electrics and finishing.
- Compliance & certificates: Part P electrics; correct ventilation; building control where required.
- Detailed written scope: Demo, prep, boards, tanking, tile areas, trims, ventilation, making good, and clear exclusions.
- Warranty: Choose a fitter who backs their work (Buildaway’s 18-month workmanship warranty).
- Local proof: Ask for Blackheath projects and references.
Smart ways to manage the budget — without compromising quality
- Keep the layout similar to avoid re-routing.
- Choose a quality mid-range suite, then upgrade brassware for feel and longevity.
- Prefer large-format tiles where suitable; fewer grout lines, faster coverage.
- Never cut corners on waterproofing — it’s the difference between “nice now” and “nice for years”.
