Who it's for Homeowners refurbishing a tired bathroom, families converting a bath-only room into a shower room, anyone fitting an en-suite into a bedroom, landlords upgrading rental properties, and downsizers wanting a contemporary, low-maintenance bathroom. When you need it When your bathroom is over 15 years old, when fixtures are leaking, grout is failing or tiles are tired, when you're remodelling a home, when adding an en-suite, or when preparing a property for sale (a modern bathroom is the #2 ROI improvement after kitchen). Why professional matters Most 'cheap' bathroom installs fall over because they use 3–4 different trades managed by the homeowner. Plumbers blame tilers, tilers blame electricians, electricians blame plasterers — and nothing matches. A single in-house team eliminates the gaps, the delays and the blame game. What it costs to delay ## The real consequences of putting it off A poorly installed bathroom doesn't just look bad — it leaks, rots, and devalues your home: ### Hidden leaks under the floor Push-fit fittings tucked into voids, untested before tile-down. Months later, the kitchen ceiling stains and £6,000 of damage emerges. ### Failed waterproofing Cement-board tile backer without a tanking membrane, walk-in shower trays with the gradient on the wrong axis, silicone joints in place of mastic — all leak within 18 months. ### Failed extractor / mould Undersized or improperly ducted extraction grows black mould in the silicone within a year. ### Electrical non-compliance Zone 1/2 lighting and sockets done by non-Part-P-certified installers — a fire and shock risk that fails any future EICR. ### No real warranty Self-managed projects have no single party to hold accountable. We've replaced cheap installs in their second year more times than we can count. ### Common mistakes we fix #### Buying the suite before the design Suite chosen on aesthetics, then forced into a room that can't accommodate it. Always design first, choose to fit. #### Skimping on the substrate Tile-backer board, primer, decoupling membrane — these are not optional. Skipping them leads to grout failure and tile crack-out within months. #### DIY electrics Bathroom electrics are notifiable under Part P. Skip the certificate and your insurance is void. Our Process ## A predictable, engineered process 1. STEP 01 ### In-home consultation We measure, photograph, discuss budgets, lifestyle and wish-list. Honest scope conversation — what's possible, what's worth doing, what isn't. 2. STEP 02 ### 3D design & specification Full 3D visual walk-through of your bathroom before any work starts. Suite, tiles, layout and lighting all to-scale. Iterate until you love it. 3. STEP 03 ### Fixed quote & schedule Itemised written quote: every fitting, every fixture, every trade. Locked-in dates, locked-in price. No 'extras' day-of-install. 4. STEP 04 ### Installation (typical 7–14 days) Strip-out, alterations, first-fix plumbing & electrics, plastering, waterproofing, tiling, second-fix, sanitaryware, joinery, lighting, ventilation, decoration. One project manager, daily clean-up, dust-screened. 5. STEP 05 ### Snag, commission & handover Pressure-test, leak-test, electrical compliance certificate, extractor flow test, snag walk-through, full clean. Operating instructions for showers, controls and lighting. 12-month workmanship guarantee. Why it pays off ## Outcomes you can measure ### One team, one accountability Plumbing, tiling, electrics, joinery and decoration delivered by Greencore engineers under one roof. ### 3D design — no surprises Walk through your bathroom in 3D before any tile is cut. Layout regrets eliminated up front. ### Fixed price, no 'extras' What we quote is what you pay. Surprises are absorbed by us, not added to your invoice. ### Predictable timeline 7–14 working days for a typical full installation. We turn up when we say, work the hours we say, finish on the day we say. ### Insurance-grade compliance Part P electrical certificate, WRAS-compliant plumbing, fully waterproofed walk-in showers. Your bathroom is insurable and certifiable. ### 12-month workmanship guarantee We come back at 12 months for a free snag visit — anything we've installed that isn't perfect, we fix. The Engineering Detail ## Under the bonnet A great bathroom is built behind the tiles. Here's what we get right that others don't: ### Waterproofing (tanking) Every wet area — full shower walls, splash zones, walk-in shower floors — receives a fully bonded tanking membrane (Aquapanel + Mapelastic or equivalent) before tile. Not silicone, not just board. This is the difference between 25 years and 2 years. ### Substrate strategy Walls: 12.5 mm cement-bonded tile backer on timber stud, taped and tanked. Floors: 22 mm ply overlay screwed to joists at 150 mm centres, decoupling membrane (Schluter Ditra), then porcelain tile. No flex, no crack-out. ### Plumbing materials Copper or polybutylene for hot/cold (push-fit on inspectable connections only — never buried). Soldered joints in inaccessible chases. Full pressure-test at first fix, recorded in writing. ### Electrical zones Bathroom IP-rated downlights, fan, mirror lighting and shaver sockets — all Part-P notified and certified. Zone 1/2 compliant fittings only, RCD-protected circuit, isolator outside the room. ### Ventilation done properly Continuous-run extractor (Vent-Axia Lo-Carbon Silhouette) ducted in rigid pipe to atmosphere via insulated route, condensate trap on cold runs. Sized to the room volume per Doc F — typically 15 l/s for a bathroom, 8 l/s for a WC. ### Underfloor heating Electric mat as standard in any tiled bathroom — 150–200 W/m² with floor probe and Heatmiser smart thermostat. Warm-floor luxury for under £600 fitted. ### Suite selection We are open-spec — work with any UK brand the client wants (Roca, Lefroy Brooks, Britton, Crosswater, Burlington, Vitra etc). We recommend the right valve/fitting brand for hard water (Darlington water is moderately hard) to maximise lifespan.
