Bathroom Renovation Cost in Northern Ireland: 2026 Price Guide

Bathrooms in older housing stock across Northern Ireland, including in Belfast, Derry/Londonderry, Lisburn and Newry, are often small, oddly shaped, or squeezed into a converted box room - so a refit is as much about layout as it is about finish.

Typical costs

• Refresh (like-for-like suite, new tiling): roughly £3,500-£6,000
• Full refit (new layout, plumbing moved): roughly £6,000-£10,000
• High-spec refit (underfloor heating, walk-in shower, feature tiling): £10,000-£15,000+

Moving the position of a bath, shower or toilet - rather than replacing it in place - is usually what pushes a job from the lower end of the range to the middle, since it means new plumbing runs and often some floor or ceiling work below.

What affects the price

Bathrooms in period properties often sit above original lath-and-plaster ceilings, so plumbers and builders need extra care - and time - when running new pipework, which is reflected in quotes. Older waste stacks and water pressure in Victorian and Edwardian housing can also mean a plumber recommends upgrading pipework beyond the bathroom itself, which is worth asking about upfront.

Getting quotes that are actually comparable

Because so much of the cost comes down to the fittings you choose, ask each builder to quote against the same fixed spec sheet (make and model of suite, tiles, taps) rather than "supply and fit bathroom" - otherwise you'll end up comparing very different jobs.
