Working in Larne

We cover every part of Larne, including BT40, and nearby Carrickfergus (9.3 miles) and Newtownabbey (13.6 miles).

Being a smaller town does not change how we work in Larne: free survey, written quote, one team. If your Larne house has a combi boiler, a loft shower can usually run on mains pressure without a pump. For a loft bathroom in a tank-fed Larne home, we work out how the shower will get its pressure before choosing a single fitting.

Most of County Antrim is supplied with soft water. If that holds for your street in Larne, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Fitted furniture made to the eaves, so the low space behind the slope becomes storage

Decisions to make first

Getting the water pressure

A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.

Roof window

A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.

Rules that apply in Northern Ireland

In Northern Ireland, building control covers the new drainage, any structural work to the floor and the ventilation, which is set out in Technical Booklet K. Wiring should be designed, tested and certified to BS 7671.

Loft bathrooms in Larne: questions

How much does a loft bathroom cost in Larne?

Is the water hard in Larne?

Does a loft bathroom in Larne need building control approval?

Building control in Larne is run by the local district council. Where approval is needed, for example for new drainage, we tell you at the survey and handle it as part of the job.

How long does a loft bathroom take?

Allow 6–12 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Larne.

How much headroom do you need for a loft shower?

Plan for around 2 m of clear height over the whole shower area, and enough standing height in front of the basin and WC. A bath can sit lower under the slope as long as you can stand up where you get in and out. We mark the usable height at each position on the survey drawing.
