Whether it's a straight refit in the same footprint or a complete redesign, we handle both. ### When you need it When your existing bathroom is dated, leaking, poorly laid out or eating into your home's value. Bathrooms are the second-highest ROI improvement after kitchens — a well-fitted one is a real asset when you come to sell. ### Why professional help matters Most bathroom problems start with plumbing under the surface — bad falls on waste pipes, undersized supplies, poor waterproofing behind tiles. Because we're plumbers first and finishers second, the parts you don't see are done to a standard that lasts. ## The cost of leaving it The gap between a bathroom that lasts 20 years and one that starts failing at year three is almost entirely down to what happens before the tiles go on. ### What can go wrong - Poorly tanked wet zones behind tiles cause hidden leaks that rot joists and destroy ceilings below — often only discovered years later. - Cheap or wrongly-specified waste falls back up into the shower tray or under the bath, creating slow drains and smells that never really go away. - Sub-standard first-fix pipework (undersized, unclipped, poor jointing) is impossible to fix later without ripping tiles off. - Multiple trades with no single point of accountability means every defect becomes 'the other trade's fault'. ### Common mistakes we see - Choosing the cheapest fitter and hoping for the best — bathroom rework is one of the most expensive things to redo. - Buying sanitaryware and tiles yourself from the cheapest supplier without checking availability and lead times — projects grind to a halt waiting for backordered items. - Skipping proper wetroom tanking or a bonded waterproof membrane to save £150 on materials. - Not planning lighting and ventilation before first-fix — retrofitting them means chasing walls that have already been re-plastered. ## Our process A clear, repeatable system — the same on every job, whether you're a homeowner or a landlord with a portfolio. 1. 01 ### Design & survey visit We visit, take measurements, talk through layout, discuss sanitaryware options, budget and lead times, and identify what's realistic in the space. 2. 02 ### Fixed written quote Itemised — strip-out, first-fix plumbing, tiling, waterproofing, sanitaryware, brassware, electrics coordination and finishing. No open-ended day rates. 3. 03 ### Strip-out & first fix Old bathroom carefully removed, floors protected, waste and supply pipework moved to suit the new layout, electrics roughed in, walls patched and prepped. 4. 04 ### Waterproofing & tiling Wet zones properly tanked, floors self-levelled where needed, tiling to your chosen pattern with straight, consistent grout lines. No shortcuts behind the walls. 5. 05 ### Second fix & handover Sanitaryware and brassware fitted, silicone finished, everything tested, room cleaned. You get a full walk-through and a written 12-month workmanship guarantee. ## What you get ### One team, one guarantee No juggling separate plumbers, tilers and electricians. One quote, one project manager, one warranty on the whole job. ### Plumbing done properly First-fix pipework sized, clipped and pressure-tested before anything gets covered up. What's behind the wall lasts as long as what's on it. ### Wet zones tanked correctly Full bonded waterproof membrane on floors and wet walls — not just a coat of paint-on tanking under the tiles. ### Real design input Practical suggestions on layout, storage, lighting and ventilation from someone who's fitted hundreds of bathrooms, not read three catalogues. ### Trusted supplier network We can source sanitaryware, brassware, tiles and lighting at trade prices — or fit customer-supplied items you've chosen yourself. ### 12-month workmanship guarantee Full written guarantee on the whole installation, on top of any manufacturer warranties. ## Recent bathroom installations work Photos from real jobs completed by Matt and the Premier Heating team.

What we're really selling is a bathroom that still looks and performs like new in 15 years. ### First-fix plumbing is everything Almost every bathroom problem we're called back to fix (weeping showers, slow drains, whistling taps, low flow) traces back to first-fix work someone rushed. We take our time on this stage — supplies correctly sized to shower demand, waste runs at proper falls, isolators on every appliance, pressure tests before anything is covered up. ### Waterproofing and tanking Wet zones (shower cubicle floor and lower walls, floor around freestanding baths, wet room floors) get a full bonded waterproof tanking system before tiling — not just a bit of paint-on. This is what stops water tracking behind the tiles into joists and ceilings. ### Wet rooms and level-access showers Level-access wet rooms need proper fall on the whole floor towards a linear or point drain, correct board substrates, and a fully tanked floor and lower walls. We spec, fall, tank and tile them so they still work and look tight in 10 years — not just on handover day. ### Sanitaryware, brassware and controls We fit whatever spec you want — from good-value ranges (Roper Rhodes, Tavistock) up to premium (Hansgrohe, Vado, Villeroy & Boch, Duravit). We can also supply and install thermostatic mixer valves with pre-set anti-scald settings, and pair them with a Vaillant or Megaflo cylinder for genuine mains-pressure showering. ### Coordinating other trades Electrics, plastering and (where needed) building work are coordinated through us — you don't have to chase separate trades. Any Part P electrical work is completed and certified by a qualified electrician working alongside us. ## Frequently asked questions How long does a full bathroom installation take?
