Bathroom installation in Cardiff, done properly.

It depends on the size of the room, the suite you choose, and how much work is involved — which is why we don't publish a single blanket figure. As a general guide, a full bathroom renovation typically starts from around £2,500–£4,000, with wet rooms, larger bathrooms, and more complex layouts costing more. Rather than give you a number that only applies to the cheapest possible job, we'll come out, take a look at your actual space, and give you a clear, fixed price before anything starts — so you know exactly what you're paying and there's no shifting goalposts once work is underway. The only exception is if we uncover something unexpected once we're into the job, like hidden water damage behind old tiles — and even then, we'll always talk to you before doing anything that changes the price.

We handle everything. JM Plumbing Services are fully qualified to carry out all the plumbing work involved in a bathroom renovation, plus the tiling, flooring, and fitting — so there's no need to find and coordinate separate tradespeople yourself, and no risk of one trade blaming another when something doesn't line up. One team, start to finish, and one point of contact if anything needs sorting afterwards. It's worth noting we don't carry out gas or boiler work — if a job needs that, we'll tell you upfront rather than take it on and get it wrong.

Most standard bathroom renovations take between 3 and 5 working days from start to finish. Larger bathrooms, en-suites with more complex layouts, or wet room installations can take a little longer, and we'll always give you a clear timeline before we begin so there are no surprises partway through. During the work you won't have full use of that bathroom, so if you've got a second bathroom or WC, we'll work around that where we can — we'll talk through the schedule with you in advance so you can plan around it properly.

Yes — JM Plumbing Services are fully insured for all bathroom fitting, renovation, tiling, and plumbing work across Cardiff and Barry, and we're happy to provide details on request before you book anything. If something isn't right once we've finished, get in touch and we'll come back and sort it — no argument. Our reputation locally is built on 25 five-star Google reviews, and that's not something we're willing to risk by walking away from a job that isn't finished properly.

No — we don't own a showroom, and that's deliberate. It means the suite and fixtures we recommend are based on what actually suits your space and budget, not whichever range a showroom needs to shift that month. If you already know the brand or style you want, we'll work with it; if you'd rather see options first, we can talk you through photos of similar jobs we've completed and point you toward suppliers directly, without the showroom mark-up sitting inside the price.

Yes. Most people who contact us haven't got a finished design in mind, just a sense of what's not working — not enough storage, an awkward layout, a bath they never use. At the free quote visit, we look at your actual space and talk through realistic layout options for it, not a generic template. If you've got inspiration photos or a Pinterest board, bring it along; if you don't, we'll suggest layouts based on similar rooms we've fitted before. You don't need a finished plan before you get in touch.

In most cases, yes. A dated or poorly laid-out bathroom is one of the first things buyers notice, and it's one of the rooms people mentally price a renovation into when they're making an offer — so an outdated bathroom can cost you more in a reduced offer than a sensible renovation would have cost to do. You don't need to go all-out: a refreshed suite, new tiling, and updated fixtures at the lower end of the £2,500–£4,000 range is usually enough to remove that hesitation, without over-investing in a house you're about to leave.
