Belfast's housing stock throws up more variety than people expect. You've got Victorian terraces around the Holylands with original cast iron pipework, 1930s semis in Belmont with airing cupboards that were never designed for a modern combi boiler, and new-build apartments off the Lagan with compact en-suites that need clever space planning. A fitter working in Stranmillis one week might be ripping out an old cylinder system, then the next be dealing with a tight ensuite in a Titanic Quarter flat where every centimetre counts. That mix of old and new means it's worth finding someone who's genuinely comfortable with both, rather than a fitter who only ever does one type of job. Local knowledge counts too, particularly around older areas like the Ormeau Road or Sydenham where soil pipe routes and stopcock locations can be a bit of a mystery until someone's under the floorboards.
The businesses listed here come from public business listings, ranked mainly by review rating and how many reviews they've collected, with a small boost given to those showing a working website and phone number. We read through each business's homepage to check that bathroom fitting is genuinely what they focus on, which stops general builders or unrelated trades sneaking onto a page like this. Any listing flagged as permanently closed gets removed as part of that same process. Where you spot a Trust Verified badge next to a business, that firm has gone further and passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. For businesses without the badge, none of that has been independently checked by us, so it's down to you to look into it before booking anything.
Before you commit to a fitter, ask to see their Gas Safe registration if they're touching boiler pipework, and their public liability insurance certificate regardless of the job size. Check whether they're registered with a trade body and ask how they handle waste removal, old suite disposal and making good the walls afterwards, since these details often get left out of quotes. Get at least two or three written quotes rather than verbal estimates, and ask each fitter to break down labour, materials and any allowance for unexpected issues like rotten floor joists or old lead pipework. A written contract with a clear timeline protects both sides if the job overruns, which happens more often than anyone would like.
How We Select & Rate The Best Bathroom Fitters in Belfast
Rankings are driven mainly by review rating and review count pulled from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm bathroom fitting is what they primarily do, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our full verification, covering qualifications, insurance, trading history, customer review history and registered company information; see our How We Verify page for the complete list. Other businesses here haven't been independently verified by us, and being included isn't an endorsement. Do your own checks before hiring anyone.

A straightforward suite swap in a standard bathroom typically runs from around £2,800 to £4,500 including labour, while a full refit with new tiling, flooring and a reconfigured layout can reach £6,000 to £9,000 or more, especially if walls are being moved or wet rooms installed. Older properties around areas like the Antrim Road or Finaghy sometimes need extra spent on pipework or damp issues before the visible work even starts. Getting two or three quotes is standard practice here, and it's worth asking each fitter to itemise labour, materials and any contingency separately so you're comparing like for like.
How long does a bathroom refit typically take in Belfast?
A basic like-for-like suite replacement can be done in three to five working days, but a full refit involving new pipework, electrics and tiling usually takes one to two weeks. Terraced houses with limited access, common around the Lower Ormeau or Sandy Row, can add time if materials have to be carried through the house rather than a side entrance. Always ask for a realistic start and finish date in writing, and build in a few days' buffer for anything unexpected turning up once the old suite comes out.
Do I need planning permission or building control approval for a new bathroom in Belfast?
Most straightforward bathroom refits don't need planning permission, but if you're adding an en-suite that changes the drainage layout, converting a loft space, or altering a listed building, Belfast City Council's building control team should be consulted first. Any work involving new soil pipe connections or moving a WC needs to comply with building regulations, and a competent fitter will know whether building control needs notifying. It's worth asking upfront rather than assuming, particularly in older properties where drainage runs aren't always obvious.
Should I choose underfloor heating for a Belfast bathroom?
Electric underfloor heating is a popular add-on for Belfast bathrooms, particularly in colder, older houses where tiled floors can feel like ice in winter. It typically adds £400 to £800 to the job depending on room size and whether floor levels need building up. Wet underfloor systems linked to the boiler are more efficient long-term but cost more upfront and need more careful planning around pipe runs, so they suit a full refit better than a quick suite swap.
What's the difference between a wet room and a standard bathroom conversion?
A wet room does away with the shower tray entirely, using a tanked, sloped floor that drains water straight into the floor gully, which suits smaller bathrooms or anyone wanting step-free access. It generally costs more than a standard shower enclosure because the tanking and floor levelling work is more involved, often adding £1,000 to £2,000 to the job. Ask any fitter quoting for a wet room what tanking system they use and whether they've fitted them before, since a poorly tanked wet room is one of the more common causes of leaks into the room below.
How do I choose between bathroom fitters in Belfast?
Start by reading through recent reviews rather than just the star rating, since detailed reviews often mention things like timekeeping, tidiness and how well a fitter communicated during the job. Ask to see photos of previous work, ideally similar in scope to your own project, and request contact details for a past customer if you're spending a significant amount. Check the fitter holds current public liability insurance and, if any boiler or gas pipework is involved, confirm they're Gas Safe registered. Get quotes in writing, ask what happens if unexpected problems are found once work starts, and clarify who's responsible for skip hire and waste disposal before you sign anything.
