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.
Whatever prompted you to look into a new bathroom, whether wear and tear, a growing family or plans to move, we can survey your Merthyr Tydfil home and give you a price in writing. Homes in Wales typically come in at £4,600–£11,000, VAT included, for this kind of work. We also cover Aberdare, Rhondda and Ebbw Vale, and the same steps apply wherever you are in Mid Glamorgan.

Local housing and a new bathroom
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
Valley terraces commonly need repointing, roof repairs, rendering and window replacement, and loft conversions can add useful space. Newer estate homes often take garage conversions, porches and landscaping.
Whatever era your Merthyr Tydfil home dates from, we plan a new bathroom around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Merthyr Tydfil
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Merthyr Tydfil comes under Wales, covered below, and we raise any questions with the council before your quote is finalised.
Internal improvements do not need planning permission in Wales unless the building is listed.
Building Regulations in Wales cover notifiable electrical work, drainage, ventilation and any structural change.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new bathroom, and photograph or measure anything the quote needs to reflect.
Price and scope agreed
After the survey we send a quote for a new bathroom that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Merthyr Tydfil property.
Finish and handover
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
What you can expect from us
Frequently asked questions
Which tiles are easiest to keep clean?
Large-format porcelain tiles are usually easiest to keep clean, because there are fewer grout lines to collect dirt and porcelain absorbs very little water. Glossy tiles show water marks more than matt ones, while textured floor tiles give better grip. Grout colour matters too: mid-grey hides staining better than white. We can suggest anti-slip ratings and grout options that suit how you use the room.
Do you cover Aberdare, Rhondda and Ebbw Vale?
Yes. As well as Merthyr Tydfil, we cover Aberdare, Rhondda and Ebbw Vale and the rest of Mid Glamorgan. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new bathroom, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
