A bathroom installation replaces your old suite with new sanitaryware, a bath or shower, tiling and fittings, including the plumbing, electrics, ventilation and waterproofing needed for a complete, watertight room.
We take on a new bathroom throughout Larne and the surrounding BT40 postcodes, as well as in Carrickfergus, Newtownabbey and Bangor, County Down. The guide range for this work in Northern Ireland is £4,300–£10,500 including VAT; where your project falls depends on its size, the materials you pick and how easy the site is to reach. A free survey turns that range into a fixed figure.

Homes in County Antrim
Belfast has long rows of red-brick Victorian terraces, Edwardian villas in the north and south of the city and large post-war estates, while towns such as Ballymena, Antrim, Larne and Carrickfergus mix terraces, semis and newer developments. Dark basalt appears in older rural buildings, and pebbledash or roughcast is a very common finish.
The north coast and glens are exposed to strong winds, salt and frequent rain, which affects render, roofline and outdoor work.
Building traditions across County Antrim also raise conservation and planning questions, so we check those for a new bathroom in Larne at the survey stage.

Internal improvements do not need planning permission in Northern Ireland unless the building is listed.
The Building Regulations (Northern Ireland) apply to structural work, drainage and ventilation; electrical work should be tested and certified.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
We look at the job
First, someone visits your home in Larne to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Quote in writing
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Booking the work
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new bathroom are in place before the first day on site.
Build and hand over
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.

Questions about a new bathroom in Larne
How long does it take to fit a bathroom?
Fitting a typical bathroom takes one to two weeks on site. Strip-out and first-fix plumbing and electrics come first, followed by any plastering or boarding, waterproofing, tiling and then the suite, taps and fittings. Wet rooms and rooms with underfloor heating take longer because screeds and waterproofing need time to cure. We give you a day-by-day plan before work starts.
Do I need a new boiler for a new shower?
You do not always need a new boiler for a new shower, but your hot water system decides what kind of shower will work well. Combi boilers suit mixer showers directly from the mains. Tank-fed systems may need a pump for good pressure, and electric showers heat their own water. We check your boiler, cylinder and water pressure during the survey and recommend a shower to match.
Can you combine a new bathroom with other work?
Yes. Because we manage several trades under one contract, we can plan a new bathroom alongside other work on your Larne home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Can I move the toilet to a different position?
Moving a toilet is usually possible, but it is limited by the soil pipe, which needs a large-diameter pipe with a steady fall to the soil stack. Short moves along the same wall are often simple, while moving it across the room may mean lifting floors or boxing in pipework. A macerator pump is an option where gravity will not work. We check the stack position during the survey.
How long will a new bathroom take?
On a typical home, allow 1–2 weeks per bathroom. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
