Ripping out a bathroom is the easy part. What decides whether the finished room lasts is the work nobody sees: the fall on the waste pipes, the tanking behind the tiles, the position of the shower circuit and how the hot water is blended. Our teams handle the plumbing, the electrics and the second fix as one job, so there is no gap between trades where problems tend to appear.

A bathroom installation in a Victorian terrace near Ealing Broadway raises different questions to one in a 1930s semi in Pinner or a purpose-built flat off Kilburn High Road. Soil stack position, joist direction, existing lead or steel pipework and the water pressure on the top floor all shape what is realistic. We survey first and tell you what the room will actually take.

Part of our plumbing services. Because heating, plumbing, electrics and appliances are all in house, a second fault found on the day does not mean a second company.

When a bathroom needs replacing rather than patching up

  • Tiles sound hollow when tapped and grout keeps failing along the bath edge.
  • Persistent damp on the wall behind the shower, or paint flaking below it.
  • The floor flexes underfoot near the WC, or the pan rocks slightly.
  • Hot water reaches the bath far too hot with no blending control fitted.
  • Waste smells linger because a trap has dried out or been bypassed.
  • Suite is cast iron or coloured and spares are no longer available.

What a bathroom installation with Home Utility covers

  • Strip out, waste removal and protection of hallways and stair carpets.
  • First fix hot, cold and waste pipework, resized where flow is poor.
  • Tanking and waterproofing to shower walls and trays before tiling begins.
  • Shower and lighting circuits installed and tested to BS 7671 zone requirements.
  • Extractor fan fitted and ducted to outside, not into a loft void.
  • Sanitaryware set, sealed, commissioned and left running with no weeping joints.
How the job runs

How a booking runs, start to finish

  • Survey and design

    An engineer measures the room, checks joist direction, stack position and incoming pressure, then sets out what will fit. You get a written quote covering labour, materials and sequence before anything is agreed.

  • Strip out and first fix

    The old suite comes out, floors and walls are made good, and pipework and cables are run to their final positions. Anything hidden behind plasterboard is photographed so you know where services sit.

  • Waterproofing and tiling

    Wet areas are tanked, boards are fixed and levelled, then tiling and grouting follow. Movement joints go in at internal corners and around the tray so the finish does not crack later.

  • Second fix and handover

    Sanitaryware, taps, shower and lighting are fitted and commissioned. We run every outlet, check for leaks under load, test the electrics and hand over certification, manuals and guarantee paperwork.

Electrical zones, water temperature and ventilation: the details that get a bathroom failed

Bathrooms count as a special location under BS 7671, and that governs where fittings may go and what protection they need. Zone 0 is inside the bath or shower tray, zone 1 sits directly above it, and zone 2 extends outward from the edge. Fittings must carry an IP rating suited to the zone they occupy, and circuits serving the room require 30mA RCD protection. In England, adding or altering a circuit in a room containing a bath or shower is notifiable work under Building Regulations Part P, so it has to be certified and registered rather than simply wired in and closed up.

Part G governs the water side. Where a new dwelling or a newly formed bathroom is involved, hot water to the bath should be limited by a blending valve so the outlet stays at a safe temperature, and cold supplies must be protected against backflow under the Water Supply (Water Fittings) Regulations 1999. Ventilation matters just as much: an extract fan needs to discharge outside through insulated ducting, because bare duct in a cold loft condenses and drips back into the fan housing.

Replacement rather than repair usually becomes the sensible route once the floor deck has gone soft, the tanking has failed behind the tiles, or the supply pipework is still lead or corroded steel.

Safe to try yourself, and what is not

Turn off the water at the stopcock if a joint starts weeping, and stop using a shower that trips the RCD. Do not cut into cables buried in bathroom walls or alter a circuit yourself; that is work for a qualified electrician under Part P and BS 7671. Any pipework touching a gas appliance is handled by our Gas Safe registered team, number 974833.

Questions we are asked most

How long does a full bathroom take?

Most single-bathroom jobs run over one to two weeks on site, depending on whether walls are moving, how much making good the floor needs and how long tile adhesive and grout need to cure. Flats with restricted access hours or a shared stack can add time. We give you a day-by-day sequence at quote stage so you know which days the room is out of use.

What does a bathroom installation cost?

Cost is driven by the size of the room, whether the layout changes, the condition of the pipework and floor underneath, the specification of the sanitaryware and whether an electric shower needs a new circuit. Moving a WC is the single biggest variable because it means altering 110mm waste. We survey, then issue a clear written quote covering labour and materials before any work starts.

Can you fit a bathroom in a flat with low water pressure?

Often, but the fix depends on the cause. Gravity-fed systems in older conversions around Maida Vale and Willesden give poor flow at the top floor, and a pump or an unvented cylinder may be the answer. Where the incoming mains supply itself is weak, an accumulator is usually better than a pump. An engineer measures static and dynamic pressure before recommending anything.

Do I need to supply the tiles and sanitaryware?

You can, and plenty of customers choose their own. We will check the specification against the room before it is ordered, because tray sizes, tap tail lengths and waste positions catch people out. If you would rather not source it, we can supply everything through our merchants and list it separately on the quote so you can see exactly what is included.
