Bathroom plumbing problems in North London properties are rarely straightforward. A leak under a basin, a shower that runs cold, a toilet that fills slowly, or damp appearing on a ceiling below a bathroom all point to faults that need proper diagnosis before any repair is agreed. At EBT Build, we carry out bathroom plumbing installations and repairs across Islington, Angel, Camden, Hackney, and Haringey as part of our wider plumbing and heating services.
Every job starts with a site assessment to confirm the fault before any work is quoted or booked. We handle everything from single fixture repairs and waste pipe replacements to full first and second fix plumbing on new bathroom layouts. All work is carried out by our own plumbers with no subcontracting, priced in writing after the assessment, and tested before any wall or floor finish is closed.

Our bathroom sink plumbing services include installation, repair, and upgrades for all sink types. We align drainage, install waste traps, and ensure systems meet UK water regulations and WRAS guidance.
We fit and repair traps, waste assemblies, flexi hoses, isolation valves, and compression fittings. Whether for bathroom sink plumbing repair or a full drain upgrade, every connection is securely fitted and pressure tested. In older homes, damaged pipes found during sink repairs may require pipework replacement
Bathroom plumbing faults in North London properties range from a leaking waste trap under a sink to a concealed pipe failure inside a wall that does not show until ceiling damage appears below. EBT Build carries out bathroom plumbing installations and repairs across Islington, Angel, Camden, Hackney, and Haringey for homeowners, landlords, and full refurbishment projects. We handle everything from first fix pipework on new bathroom layouts to fault finding and repair on existing systems, with every job tested before walls or floors are closed. Where a bathroom requires hot water from a new or upgraded heating system, this is assessed alongside the plumbing work and connected to the existing boiler installation and servicing as part of the same job.
A bathroom sink that drains slowly, leaks under the cabinet, or has inconsistent water pressure has a plumbing fault, not a fixture problem. We install and repair bathroom sink plumbing across North London covering hot and cold feed connections, waste trap installation, isolation valve fitting, and waste pipe alignment to the correct gradient. Every connection is pressure tested and every joint is checked before the cabinet is closed.
We install, replace, and repair toilet and cistern plumbing for homeowners and landlords across Islington, Camden, Hackney, and Haringey. This includes close coupled and concealed cistern installations, soil stack connections, flush mechanism replacement, and isolation valve fitting. Where a toilet is being relocated, we assess the soil stack position and waste gradient before any work is agreed to confirm the layout is viable.
Shower plumbing involves more than connecting a head to a pipe. Flow rate, pressure balancing between hot and cold supplies, thermostatic mixer valve installation, and waste pipe gradient all affect how the shower performs. We install concealed and exposed shower plumbing systems, thermostatic and manual mixer valves, shower tray waste connections, and overhead and handheld shower configurations. All work is carried out to WRAS standards before tiling or wall finishes are fitted.
Bath installation requires correct hot and cold feed sizing, a properly sealed waste and overflow assembly, and a waste pipe connected at the correct gradient to prevent slow drainage and trap siphonage. We install freestanding and built-in bath plumbing including tap connections, waste fitting, overflow assembly, and waste pipe routing to the main drainage stack. Every installation is tested for flow and leak-free performance before the bath panel or surround is fitted.
Older bathroom pipework made from lead, iron, or degraded copper causes low pressure, discoloured water, and recurring leaks that surface repairs cannot fix. Where a bathroom inspection identifies pipework that is beyond repair, we carry out targeted or full pipework replacement using copper or WRAS approved barrier pipe, correctly sized for the fixtures being supplied. All new pipework is pressure tested and insulated where required before walls or floors are closed.
A bathroom leak that is not visible at the surface is usually more serious than one that is. Damp patches on ceilings below bathrooms, unexplained pressure drops, and mould around walls and floor edges are all signs of a concealed leak inside the floor or wall structure. We carry out leak detection using moisture mapping and acoustic tracing to confirm the source before any surface is opened, then carry out the repair and test the system before reinstatement.
Bathroom plumbing done incorrectly does not fail immediately. A waste pipe laid at the wrong gradient drains slowly for months before the trap siphons and sewer gas enters the room. A compression joint fitted without the correct insert collapses under repeated pressure changes and leaks inside the wall. A shower mixer installed without balancing the hot and cold supplies scalds or runs cold. At EBT Build, every bathroom plumbing job is carried out by qualified plumbers who work to WRAS standards and CIPHE guidance, and every connection is tested before any surface is closed.
We carry out bathroom plumbing across Islington, Angel N1, Camden, Hackney, and Haringey for homeowners, landlords, and property managers. Every job is handled by our own plumbers with no subcontracting, every repair is confirmed leak free before we leave, and every project is priced in writing after a site assessment with no costs added once work begins. Where a property requires plumbing work in both the bathroom and kitchen, we coordinate both under one visit our kitchen plumbing service covers sink installation, waste connections, and appliance feeds as part of the same managed job.
We provide targeted upgrades, including bathroom plumbing system improvements, replacing PEX or copper feeds, installing isolation valves, and fixing drainage issues. Smaller jobs include moving bathroom sink plumbing, shower waste realignment, and vent pipe improvements for better drainage flow.
Before starting, we assess existing pipelines, pressure levels, venting arrangements, and water quality to ensure all upgrades remain compliant and cost-effective.
We specialise in complete bathroom rebuilds including first-fix and second-fix plumbing. This includes bathroom tub plumbing, shower mixer installation, toilet waste systems, concealed pipework replacement, and drainage redesigns.
The project begins with a full inspection of visible and concealed pipework. We trace leaks, blockages, slow drains, sewer smells, or pressure issues before any work begins.

Bathroom plumbing costs in London depend on the scope of work, number of fixtures, and whether concealed pipework is involved. A single fixture repair such as a leaking trap or slow draining waste typically costs between £80 and £200 including labour and parts. A full bathroom first and second fix plumbing installation on a standard three piece bathroom suite costs between £800 and £2,500 depending on pipework complexity, fixture type, and access. Shower plumbing with a thermostatic mixer valve and concealed pipework costs between £400 and £1,000 depending on the installation. EBT Build provides a written quote after a free site assessment so you know the full cost before any work begins.
A single fixture repair or replacement such as a toilet cistern, basin waste, or shower mixer typically takes two to four hours. A full bathroom plumbing installation covering basin, toilet, bath, and shower on a new layout takes two to four days depending on whether pipework needs rerouting and how much concealed work is involved. First fix plumbing on a full bathroom refurbishment is usually completed before tiling begins, with second fix connections made after tiles and wall finishes are fitted. EBT Build confirms timelines in writing before work starts so you have a clear programme for the full project.
First fix plumbing is the pipework that goes behind walls and under floors before any tiling or decoration is done. It includes hot and cold supply pipes, waste pipes, soil stack connections, and any concealed shower or bath connections that need to be in place before the room is finished. Second fix is everything that connects to those pipes after the room is decorated, including fitting taps, connecting waste traps, installing the toilet cistern, and connecting the shower mixer. Both stages need to be carried out correctly as mistakes in first fix are expensive to access and repair once walls are tiled.
A sewage smell in a bathroom is almost always caused by a dry or siphoned trap. Every sink, bath, shower, and toilet in a bathroom has a trap — a water-filled bend in the waste pipe that blocks sewer gas from entering the room. If a fixture is used infrequently the water in the trap evaporates, if the waste pipe gradient is incorrect the trap siphons dry after every use, or if the vent pipe is blocked the trap gets pulled dry by drainage pressure. Running water into unused fixtures usually fixes a dry trap temporarily. A recurring smell means the vent pipe or waste gradient needs professional assessment.
In some cases yes, depending on the fault. Trap replacements, isolation valve repairs, cistern mechanism replacements, and waste pipe adjustments under a basin can usually be carried out without disturbing tiles. Concealed pipe faults inside walls or floors, shower valve replacements behind tiled surfaces, and bath waste repairs under a tiled panel all require access to the surface. EBT Build carries out leak detection before opening any surface to confirm exactly where the fault is and limit the area that needs to be disturbed.
Damp patches on walls or ceilings below a bathroom, soft or discoloured flooring around a bath or shower tray, mould appearing at wall and floor junctions, unexplained drops in boiler pressure, and a water meter that continues to move when all fixtures are off are all signs of a concealed leak. By the time visible damage appears the leak has usually been running for weeks or months. EBT Build carries out leak detection using moisture mapping and acoustic tracing to locate the source before any surface is opened.
