- One in-house project manager from first fix to final test, not a chain of separate trades to chase yourself
- 5-year guarantee on labour and installation, plus a 2-year guarantee on products
Supply Pipes, Waste Runs and Drainage Work Covered
- Extending and rerouting hot and cold supply pipes to new basin, bath, shower and toilet positions
- Waste pipe runs for basins, baths and showers, including the fall needed for reliable drainage rather than a slow-draining shower tray
- Wet room and walk-in shower drainage, including linear or point drains, and pump-assisted units where a gravity fall isn't achievable
- Central heating pipework extended or rerouted for heated towel rails and radiators
- Shower valve and mixer installation, including concealed thermostatic valves
- Toilet relocation, including waste pipe diversion and macerator (Saniflo-type) installation where gravity drainage isn't an option
- Boxing in surface-run pipework so it's hidden behind panelling rather than left exposed
- Isolation valves fitted at each appliance, so a washer or valve can be serviced later without shutting off water to the whole house
Not Included / Costed Separately
- General household plumbing unrelated to the bathroom project, such as kitchen taps or outside taps
- 24-hour emergency call-outs for burst pipes - this is planned installation work booked in advance, not an emergency plumbing service
- Boiler installation, service or repair itself (only the pipework connecting into it as part of a towel rail or radiator run)
- Clearing blocked drains or shared soil stacks beyond the bathroom's own waste connection
- Any plumbing not included in the itemised fixed quote - if something's added mid-job, it's priced and agreed before work continues, not billed as a surprise afterwards
First Fix, Second Fix and the Pressure Test That Follows
- Free home consultation -- A member of the team visits, looks at where your current pipes actually run (not just where a floor plan suggests they should), checks water pressure, and discusses what you want to change - moving a toilet, adding a wet room, fitting a bigger shower.
- Design, plumbing plan and fixed quote -- You get CAD or 3D drawings alongside a plumbing layout showing exactly where supply and waste pipes will be extended or rerouted, with an itemised fixed quote - not a verbal estimate that shifts once the plaster comes off.
- First fix -- Existing pipework is opened up, new supply and waste runs are laid in, and the positions for the shower valve, toilet waste and basin are set out and pressure-tested before any boarding or tiling goes over the top.
- Second fix and connection -- Once tiling and boarding are complete, taps, the shower valve, toilet, waste traps and towel rail are connected, and every joint is checked for leaks under running water rather than just visually.
- Commissioning and handover -- The system is flushed through, water pressure and drainage are tested at every point, and you're shown where the isolation valves are so a future job - a new washer, a service - doesn't mean turning off water to the whole house.
What Plumbing Adds to Your Bathroom Quote
Plumbing is rarely priced as a stand-alone line - it's bundled into the labour cost of the wider bathroom job, and that labour typically makes up somewhere between 45% and 60% of a full renovation, working out at roughly £1,800 to £4,000 in labour on an average bathroom, according to Checkatrade's 2026 cost data. Where a job includes a wet room conversion with proper drainage falls, specialist labour for that alone tends to run at around £240 to £320 a day, per BookaBuilderUK's 2026 figures - wet room plumbing takes longer to get right because the whole floor build-up depends on the drainage being correctly set out before anything else happens. On top of the plumbing itself, a full bathroom design, supply, installation and project management typically starts from around £5,000, depending on room size, the products chosen, and whether wider building work - moving a stud wall, upgrading electrics - is needed alongside it. None of these figures replace an actual quote: what your plumbing costs depends on where your existing pipes run, how far they need to travel, and what's hidden behind your walls, which is exactly why a fixed price only gets given after someone's been out to look at the room.
A Plumber on Their Own vs Plumbing Inside a Managed Bathroom Project
| What matters | General plumber (bathroom plumbing only) | Derby Bathroom Fitter (in-house team) |
|---|---|---|
| Waste and supply pipe rerouting | Usually covered | Covered, planned around the full room layout |
| Coordinating tiling, electrics and plastering around the plumbing | Left to you to schedule and chase | Handled by one project manager throughout |
| Gas Safe engineer for any gas-related pipework | Often needs sourcing separately | In-house Gas Safe registered engineer |
| Guarantee on the finished plumbing work | Varies by individual tradesperson | 5-year guarantee on labour and installation |
| Single point of contact if something needs revisiting | Not always | Same project manager from quote to handover |
Qualified to NVQ and City & Guilds Standard, Every Time
Every supply and waste run is carried out by plumbers trained to NVQ Level 2 and City & Guilds standard, so the fall on a shower waste or the position of an isolation valve isn't a guess made on site - it's set out the way the trade's meant to be done. Where a job ties into gas central heating pipework, such as extending a run to a new towel rail or radiator, that connection is made by a Gas Safe registered engineer, because that's what the law requires for anything touching a gas appliance or its pipework, not an optional extra. Between the team there's more than 20 years of hands-on plumbing and bathroom-fitting experience, and it shows up less in claims and more in the detail - checking a wall's actual pipe route before opening it up, testing
every joint under running water rather than eyeballing it, and knowing which older Derby properties are still running galvanised supply pipe that's worth replacing outright rather than extending. That work carries a 5-year guarantee on labour and installation and a 2-year guarantee on any products fitted, so a shower valve or macerator that plays up while it's still under guarantee gets sorted without an argument about whose fault it was.
Different Derby Streets, Different Pipe Runs
Most of the work happens in Derby itself, and the city's mix of building ages shapes a lot of how it gets planned. Cathedral Quarter apartments and terraces near Derby Cathedral often have older, narrower pipe runs that need careful extending rather than a straightforward tap-in, while the newer estate housing around Mickleover, Littleover and Breadsall generally has more accessible routing through stud walls and loft space. Areas like Allestree and Darley Abbey, close to Darley Park and the Silk Mill along the River Derwent, tend to bring a mix of both - period stone-built houses alongside more recent infill, so the pipework survey at the start of a job matters more than usual. Out towards Spondon, Alvaston and Chellaston, in the commuter belt around Pride Park, plumbing work is more often about extending into a modern loft conversion or en-suite than working around old pipework. Further along the Derwent Valley towards Belper, Duffield and Milford - inside the Derwent Valley Mills UNESCO World Heritage corridor - waste routing changes on older or listed properties sometimes need extra thought around what's visible from outside, and that gets factored into the plan before work starts. Up towards Matlock, Bakewell and Ashbourne on the edge of the Peak District, older stone cottages can still have galvanised or lead supply pipework that's better replaced outright than extended, which is worth flagging early rather than discovering once a wall's been opened up. Derby's water is also hard, which over time furs up shower valve cartridges and thermostatic mixers faster than in soft-water areas - worth knowing if your existing shower has been getting stiffer to adjust. Beyond the city, the same service covers Long Eaton, Ilkeston, Ripley, Heanor, Swadlincote, Burton on Trent, Alfreton, Willington, Repton, Buxton, Borrowash, Quarndon and Markeaton, and further out into Nottingham, Sheffield and the wider Nottinghamshire area.
Questions About Pipes, Pressure and Drainage
Do you fix leaking bathroom pipes, or only fit new bathrooms?
The focus is full bathroom installation rather than general repair call-outs, so a leak on its own - unrelated to a bathroom project - isn't something to expect a same-day fix for. Where a leak turns up during a design consultation or while work's under way on your bathroom, it gets sorted as part of that job. If you need an emergency plumber for a burst pipe with no bathroom work planned, that's a different service to what's offered here.
How much does it cost to reroute bathroom plumbing?
It depends on how far the pipes need to travel and what's in the way - a straightforward extension to move a basin along the same wall costs a lot less than rerouting waste pipes to move a toilet to the opposite side of the room. As a rough guide, labour across a full bathroom job typically runs to somewhere between £1,800 and £4,000, with plumbing making up a good share of that. A firm figure only comes after someone's seen the room and the existing pipe runs.
Can you install a new shower valve or mixer?
Yes, including concealed thermostatic valves, which are the most common request on newer installations because they hold a steady temperature and don't leave exposed pipework to clean around. Fitting one properly usually means opening up the wall behind the shower to get the valve body and pipework in the right position before tiling goes on.
Do you deal with low water pressure in showers?
Low pressure is usually down to one of a few things - undersized supply pipework, a shower valve that isn't matched to the property's system (gravity-fed versus combi or unvented), or, in Derby's hard water areas, limescale build-up inside an older valve cartridge. Part of the initial visit is checking which of those applies before recommending a fix, rather than assuming a new shower head will solve it.
Can you move a toilet to a different part of the bathroom?
Yes. It means diverting the waste pipe to the new position with the correct fall to the soil stack, which is usually the biggest single factor in how much a bathroom reshuffle costs. Where the new position doesn't have a workable gravity fall - a common issue in layouts where the toilet needs to sit some distance from the existing stack - a macerator (Saniflo-type) unit is fitted instead, pumping waste to the nearest connection point rather than relying on gravity alone.
Are your plumbers Gas Safe registered?
Plumbing is carried out to NVQ Level 2 and City & Guilds standard. Where a job involves gas-related pipework - for instance, tying new radiator or towel rail pipework into an existing gas central heating system - that part is handled by a Gas Safe registered engineer, as required by law for any work on gas appliances or connected pipework.
How long does it take to replumb a bathroom?
The plumbing itself is usually done across the first-fix and second-fix stages of a wider bathroom installation, so it's rarely timed on its own. On a standard family bathroom, first-fix plumbing (opening up, new pipe runs, pressure testing) typically takes a day or two, with second fix (connecting taps, valves and waste) coming later once tiling's finished. A wet room adds time because the drainage and floor falls have to be right before anything else can go on top.
What building regulations apply if you're changing waste pipe routing?
Altering how waste water drains from a bathroom falls under Building Regulations Part H, and depending on what's changing - particularly if you're adding a new soil pipe run or altering the route to the main drain - it can need notifying to Building Control, either directly or through a competent person's scheme. This gets checked at the design stage so it's factored into the plan rather than becoming a problem once the pipework's already in the wall.
Get the Pipework Booked in Before the Tiler Arrives
Pipework hidden behind tiles is the hardest part of a bathroom to fix once the room's finished, so it's worth getting right the first time rather than working around a rushed job later. Because only one bathroom is taken on at a time, booking a free home consultation now means your job gets a dedicated project manager from the first pipe run to the final test, not a slot squeezed in between two other projects. Get in touch to arrange a visit and a fixed quote for the plumbing your bathroom actually needs.
