Bathroom renovation in Cardiff.
A complete bathroom renovation in Cardiff, handled start to finish by one team — strip-out, plumbing, tiling, and fitting, with a fixed price agreed before anything starts.
At a glance JM Plumbing Services carries out full bathroom renovations across Cardiff — strip-out, plumbing, tiling, and fitting from one accountable team, with a fixed price agreed upfront.
What does a full renovation actually involve?
A renovation means everything comes out and everything goes back in properly — old suite, tiling, and pipework stripped out, then new plumbing, waterproofing, tiling, and fittings installed to work as one finished space, not a patched-together mix of old and new. Most standard renovations take 3–5 working days from start to finish; larger bathrooms, en-suites, and wet rooms can take a little longer, and we'll always give you a clear timeline before we begin.
If your bathroom just needs individual elements replaced rather than a full renovation, see our bathroom installation page instead. We handle the plumbing, tiling, and flooring ourselves rather than passing you between separate tradespeople — see our tiling and LVT & vinyl flooring pages for more on those specifically.

Bathroom Renovation FAQ
Questions about renovating your bathroom.
How much does a bathroom renovation cost in Cardiff?
As a general guide, a full bathroom renovation in Cardiff typically starts from around £2,500–£4,000, depending on the size of the room, the suite you choose, and how much work is involved. Wet rooms, larger bathrooms, or more complex layouts will cost more. The only accurate way to get a number for your specific bathroom is a free, no-obligation quote — we'll visit, take a look, and give you a clear fixed price before anything starts.
Will the price change once work has started?
No — we always agree a fixed price before starting, and in the vast majority of jobs it stays exactly as quoted. The only exception is if we uncover something unexpected mid-job, like hidden water damage behind old tiles, and even then we'll always talk to you before doing anything that affects the price.
Do you supply the bathroom suite and materials, or do I?
Either works for us. We can source and supply everything — suite, tiles, fixtures, and fittings — or we can work with materials you've already bought, and we'll advise on specifications and measurements if you're buying your own. We can't be responsible for the quality of customer-supplied materials, though.
Do you fit wet rooms?
Yes — we install wet rooms as well as standard bathrooms and en-suites. Wet rooms need careful waterproofing and drainage installation, which is something we're experienced in and take seriously, since it's the part that causes problems years later if it's rushed.
Is it worth renovating a bathroom before selling?
In most cases, yes. A modern, clean bathroom is one of the first things buyers notice and can add real perceived value to a property. You don't need to spend a fortune — a refreshed suite, new tiling, and updated fixtures can make a genuine difference to how a property presents during viewings.
