Strip-out, replumb to current regs, tanking, screed, underfloor heating where wanted, tile, grout, silicone and fit-out. ### Who It's For Homeowners replacing a tired bathroom; landlords turning round rental bathrooms between tenancies; renovators rolling a bathroom into a wider scheme; anyone who's been quoted by a bathroom showroom that supplies but doesn't fit, or a fitter who doesn't tank. ### When You Need It Once you've settled on the layout and the suite, and the rest of the house programme allows for 7–14 days without a working bathroom — or with the right family logistics, longer. ### Why It Matters Bathrooms fail at the tanking step. A bathroom fitted by a kitchen fitter, plumber or general handyman skipping the tanking system will leak into the ceiling below inside 12–24 months — and the damage is structural, not cosmetic. The unglamorous bits decide the lifespan. What Happens If You Wait ## The Cost OfDoing Nothing. A leaking bathroom is the most expensive failure in domestic construction. Joists rot, ceilings come down, insurance gets argued. ### Risks Of Ignoring It - →Wet rooms tiled before tanking — water in the joists, ceiling down below within 18 months. - →Pipework run in floor voids without access — first leak means a floor up. - →Tile grout failing because of substrate movement — water gets behind the tiles. - →Silicone bead applied over dirty surfaces — peels off, water tracks behind. - →Wrong board behind tiles — paper-faced plasterboard under a shower, not tile-backer. ### Common Mistakes Customers Make - ×Buying the suite before measuring up properly. - ×Letting a kitchen fitter 'do the bathroom too'. - ×Skipping underfloor heating then regretting it forever. - ×Specifying glass-only screens where a half-height wall would work better. Our Process ## First Call ToFinal Sign-Off. 01 ### Survey & Spec Measure up, agree the layout and suite spec, check existing services, photograph everything before strip-out. 02 ### Fixed Written Quote Itemised written quote — strip-out, plumbing, tanking, tile spec, suite, second fix, decoration. 03 ### Strip & First Fix Bathroom stripped to brick or stud, pipework reset to current regs, electrical first fix, tile-backer board where required. 04 ### Tank, Screed & Tile Full tanking system to walls and floor in wet areas, screed to fall, underfloor heating laid, tile and grout to spec. 05 ### Fit & Sign-Off Suite installed, silicone beaded properly, tested under pressure, snags fixed same day, paperwork handed over. Why It's Worth It ## What YouActually Get. ### Tanking Done Properly Full liquid or membrane tanking system to walls and floor in any wet area — the bit that stops your ceiling coming down next year. ### Water Where It Belongs Falls cut into the screed, pipework pressure-tested, traps accessible, silicone beaded to clean surfaces. No surprises. ### Tile-Ready Substrate Tile-backer board behind tiled walls, not paper-faced plasterboard. The substrate decides whether the tiles still look right in five years. ### Underfloor Heating Option Wet or electric UFH laid under tile when specified — quiet, even warmth and no ugly radiator on the wall. ### One Quote, One Team Plumber, tiler, electrician and joiner all run on one programme by one accountable team. No three-trade booking dance. In Detail ## Bathroom Renovations —Every Variation Covered. Materials, methods and the situations each variation applies to — so you know what you're buying before you buy it. Working across Pontypridd · Rhondda · Ynysybwl & Abercynon · Talbot Green · Aberdare · Merthyr Tydfil · Caerphilly Full Service Area Map ### Family Bathrooms Bath plus separate shower or shower-over-bath, vanity unit, WC and storage to a domestic spec built to last the next 10–15 years. Standard suite or your supplied kit. ### Wet Rooms & Walk-In Showers Fully tanked floor and walls, screed-to-fall, linear or point drainage, frameless glass screens, large-format tiles. The bit that fails most often when done by anyone but a properly trained fitter. ### En-Suites & Cloakrooms Compact layouts where every millimetre counts — pumped soil systems where gravity won't reach, slimline suites, sliding or pivot doors. Same tanking standard as a full bathroom. ### Rental & Landlord Turnarounds Hardwearing, easy-clean specs designed for tenant turnover — durable tile, simple silicone joints, accessible plumbing for the next leak fix. Fast programme between tenancies. ### Period Property Sensitivity Bathrooms inside Victorian or Edwardian terraces sometimes need solid-wall detailing — lime-friendly fixings, breathable build-ups where possible, and pipework routes that don't notch joists into oblivion. Questions ## StraightAnswers. Cost, timeline, guarantees, lifespan, emergency availability — the questions everyone asks, answered before you call. Ask Yours ### How much does a new bathroom cost in South Wales? +Cost depends on suite spec, tile choice, layout changes and any structural work. We give itemised fixed written quotes after a site visit so you can see exactly what each element costs. ### How long does a bathroom take to fit? +A straightforward replacement bathroom is typically 7–10 working days. A full strip, replumb, tank, tile and fit usually runs 10–14 working days. Wet rooms with screed-to-fall and underfloor heating add a few days. ### Do you supply the bathroom suite or do I? +Either works. We can spec through trade suppliers we trust or fit suites you've bought yourself — just want to see the spec before pricing labour so we don't undersize a soil run. ### Do you tank every bathroom? +We tank every wet area as standard — full tanking system to walls and floor inside shower enclosures and wet rooms. Family bathrooms with bath-only get the wet zones tanked. ### Can you install underfloor heating? +Yes — wet or electric, laid under screed before tile. Specify at quote stage so we set the floor build-up correctly. ### Will I be without a bathroom for the whole job? +Yes — once the strip starts the room is out of action until the end. For households without a second bathroom we'll talk through options before quoting. ### Do you take a large deposit? +No. We work on stage payments against completed milestones, not large up-front deposits. You're paying for work done. ### Do you handle electrical certificates for the bathroom? +Yes — Part P electrical work is signed off and certificated, bundled into the handover paperwork.
