Bathroom fitting: fit-only or supply and fit

Bathroom fitting is the installation work itself: removing the old bathroom, running pipework and wastes, boarding and tiling, and fitting the suite, furniture and brassware. You can buy the products yourself and pay for fitting only, or have the fitter supply everything.

From £2,200 inc VAT4–8 working daysFree home survey
Bathroom fitter installing a basin and vanity unit

Plenty of people choose their bathroom online or from a merchant and then need someone to install it. That works well when the products suit the room and arrive complete. It goes wrong when a basin waste does not match the vanity unit, a shower valve needs more pressure than the system gives, or the WC pan does not line up with the soil pipe. On fit-only jobs, most delays come from parts rather than labour.

We fit suites that customers have bought, and we supply and fit complete bathrooms. For fit-only work, we check your product list at the survey and again before the start date, so gaps are found early. Labour for the same layout typically costs £2,200 to £4,000 including VAT; a new layout with re-routed pipework is £3,500 to £6,000. Either way, the quote sets out what we do and what you supply.

What does bathroom fitting with us include?

  • A survey of the room, the supplies and drainage, and the products you plan to use
  • A check of your product list against the room and the plumbing before the job is booked
  • Unpacking and checking delivered items before day one, so damage or missing parts can go back to the seller early
  • Strip-out of the old suite and tiles, and removal of the waste
  • First and second-fix plumbing: supplies, wastes, isolation valves and the connection to the soil stack
  • Boarding, tanking in the shower area and tiling labour, with tiles and adhesive from you or sourced by us
  • Electrical work by a qualified electrician where lights, a fan or a shaver socket are changing
  • Fitting the suite, furniture, screen and accessories, then silicone, testing and a clean handover

What do you need to decide?

Fit-only or supply and fit

Fit-only lets you choose and buy every product yourself; supply and fit puts sourcing, deliveries and returns on us, with one price for everything.

Who buys the materials

Adhesive, grout, boards, tanking, wastes and fixings can come from you or from us. The quote says which, so nothing is assumed.

Same layout or new

Keeping the layout keeps labour in the £2,200 to £4,000 range; moving the WC, shower or basin adds pipework and days.

Delivery timing

Having everything delivered and checked before the start date avoids a half-finished room while a missing part is sent again.

Tiling

Some customers tile themselves or use a separate tiler. That can work, but the order of trades and who tanks the shower area must be agreed first.

Making good

Decide whether you want the quote to cover making good and decorating, or to stop at the tiles so you can paint yourself.

How does the job run?

  1. Survey and product check

    We see the room, check the plumbing and electrics, and go through the products you have bought or plan to buy.

  2. Written quote

    The quote lists labour, any materials we supply and the items you are supplying, so responsibilities are clear.

  3. Deliveries checked

    Before the first day, your products are unpacked and checked against the list, and any missing or damaged items reported.

  4. Strip-out and first fix

    The old bathroom comes out, supplies and wastes are set for the new suite, and walls are boarded and tanked.

  5. Tiling, fitting and handover

    Tiles go on, the suite and furniture are fitted, and everything is tested and sealed before handover.

Who is it right for?

  • Customers who have already bought their suite, or found one in a sale
  • Landlords and developers buying the same products for several properties
  • Homeowners who want strip-out, plumbing, tiling and electrics handled around products they chose themselves
  • Like-for-like refits where the layout stays the same

What should you watch out for?

  • Check the WC pan outlet, soil pipe position and cistern type match before buying; back-to-wall pans and concealed frames need the right depth of boxing
  • Buy the right waste for each basin: slotted for a basin with an overflow, unslotted for one without
  • Check the minimum pressure your shower valve and taps need against what your gravity, combi or unvented system gives
  • Keep the boxes and paperwork until fitting is finished, because faulty items go back to the seller

What rules apply to bathroom fitting?

When you supply the products, you are responsible for them being complete, undamaged and suitable, and a claim for a faulty item goes to the retailer or manufacturer you bought it from. We are responsible for the fitting, which under the Consumer Rights Act 2015 must be carried out with reasonable care and skill. Products must also meet the water fittings rules where you live, including a maximum 6-litre flush for new WCs and backflow protection, so we raise anything that looks non-compliant before fitting it.

England

In England, the Water Supply (Water Fittings) Regulations 1999 apply to the products you supply as well as to the installation. Electrical changes such as new lights or a fan are notifiable under Part P and are done by a registered electrician or notified to building control. New drainage or a new connection to the soil stack can be Part H work.

Wales

Wales uses the same water fittings regulations as England but has its own Part P with a wider notifiable list, so more of the electrical side of a refit needs notifying. A registered electrician handles this and gives you the certificate.

Scotland

In Scotland, the Scottish Water Byelaws 2014 cover new taps, WCs and showers, whoever bought them. A like-for-like fit rarely needs a building warrant; a new layout that alters drainage may. Electrical work is tested and certified to BS 7671.

Northern Ireland

In Northern Ireland, the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 apply to supplied products, and building control covers new drainage and ventilation. Electrical work follows BS 7671 good practice, with testing and a certificate.

FAQ

Bathroom fitting: your questions answered

How much do bathroom fitters charge?

Fit-only bathroom installation typically costs £2,200 to £4,000 including VAT when the layout stays the same, and £3,500 to £6,000 when pipework and wastes move for a new layout. That covers strip-out, plumbing, boarding, tiling labour and fitting; tiles, adhesive and electrics depend on who supplies them. Full supply and fit usually comes to £6,500 to £12,000.

How long does it take to fit a bathroom you have supplied?

A fit-only bathroom usually takes four to eight working days. Same-layout jobs with tiling to the wet areas sit at the shorter end; a new layout, full-height tiling, a tiled shower floor or plastering push it towards eight days.

Will you fit a bathroom suite I bought online?

Yes. Send us the product list or links before the survey, and we will check sizes, wastes, valves and the cistern type against your room and plumbing. Missing or mismatched parts cause most fit-only delays, and they are far easier to sort before the start date than halfway through.

Who is responsible if a product I supplied is faulty?

If you bought the product, a fault with it is a matter for the retailer or manufacturer that sold it to you. We are responsible for our fitting work. If a fault shows up during fitting, we stop, show you, and help you describe it to the seller; fitting a replacement part can add labour, which we agree with you first.

What does a bathroom fitter do?

A bathroom fitter removes the old bathroom, installs new pipework and wastes, boards and prepares the walls, tiles, and fits the bath or shower, basin, WC, furniture and accessories. Electrical work in a bathroom is done by a qualified electrician, and any gas work, such as moving a boiler, by a Gas Safe registered engineer.

Should I buy my own bathroom suite or let the fitter supply it?

Buying your own gives you full choice and can save money in a sale, but you take on deliveries, checking every box and any returns. Supply and fit puts that on the fitter and gives you one price for everything. If you are unsure, ask for both options on the same quote. See fitted bathrooms for supply and fit.

Do bathroom fitters do the tiling?

Most do, and our fit-only quotes include tiling labour unless you ask otherwise. Tiles, adhesive and grout can come from you or from us. Supplied and fitted, bathroom tiling costs £45 to £90 per m² for most ceramic and porcelain.

What should I have ready before the fitter arrives?

Have every product delivered, opened enough to check, and stored somewhere dry near the bathroom. Clear the room and the route to it, and expect the water and toilet to be off at times. If this is your only bathroom, plan where you will wash on the days the shower is out of use.
