How Much Does a New Bathroom Cost? (Installation & Fitting)

If you have the same bathroom suite that came with the house, then the chances are that it may have become drab and dated by now. Perhaps, now is the time to consider buying a new bathroom suite, with up-to-date fitments. Perhaps you should remodel for a fully fitted bathroom or install an additional toilet somewhere? Or, you intend to move house and you want to ask as much as you can for your property.

Whatever your situation, they are all good reasons to invest in an updated or extended bathroom and toilet. 

Generally, new bathrooms depend on how much you can pay and how many and what quality fitments you want. An average cost of a new bathroom installation (standard range) would be in the region of £2,500 to £6,500. Prices in London and Southeast will be about 20% higher than the remainder of the country, which works out to be between £3,000 and £7,800. And, you should add VAT on top of this.

Bathroom Installation Cost Calculator: Maximising Value (examples)

Let’s look at some cost estimates in more detail, ranging from basic up to luxury bathrooms. 

Bathtub 

This is probably the most important thing to have in a bathroom. The clue is in the name!  

A lightweight acrylic bath is probably the cheapest you can buy at about £80 to £100, but it’ll need a frame and tiling around it. A highend freestanding acrylic bathtub is more stable and less flexible so doesn’t need a frame. These will be anything from £250 to £1500 and more.  

Probably, a basic steel bathtub is the best value for money starting from about £120. More expensive ones include cast iron and polished stone tubs.  

Fitting a bathtub will take about 3 to 5 hours irrespective of the price range. 

  • Low-end: £80 
  • Midrange: £250 to £650 
  • Luxury: £250 to £1500 

Shower 

The cheapest type is an electric shower unit that only needs a cold water feed. These can be as cheap as £50 to £70. They only need an electrical connection to heat the water inside the unit. However, these can be temperamental if you have low domestic water pressure and someone else in the house turns on the cold tap, reducing the cold feed to the shower. 

A basic shower mixer using hot water heated elsewhere, and mains cold water costs about £60. A thermostatic mixing valve keeps the temperature constant when water pressure varies and these cost at least £130. Sometimes, a mixer tap connects to the bathtub taps. And, a combination bathtub shower is another cheap option as you don’t need a shower enclosure or a tray. These cost about £50. 

There are many types of luxury shower. If you suffer from low water pressure, a power shower uses a booster pump to raise the water pressure. These cost from £150 upwards. Showers using digital technology provide pulsing jets and sprays and cost at least £250. 

Apart from the shower bathtub combination, you’ll also need a shower enclosure. These include a frame, door and shower tray and can cost from as little as £50 up to at least £500. 

Installing a shower unit can take 2 to 3 hours. 

  • Low end: £50 
  • Midrange: £60 to £500 
  • Luxury: £500 to at least £2,000

Toilet 

Now, a toilet might be in the bathroom or it might be in a separate room. Wherever you have the toilet in your house, a basic floormounted pan costs about £50. Luxury ones cost anything up to £500. You can buy wall mounted pans as well as taller ones suitable for the elderly and disabled. It’s your choice. A plumber takes about 2 to 3 hours to install a toilet. 

  • Low end: £50 
  • Midrange: £100 to £300 
  • Luxury: £300 to at least £500 

Washbasin 

The styles vary from pedestal mounted, wallmounted and vanity unit basins. The basic pedestal mounted model costs about £50. A semi pedestal or wallmounted basin will also be a cheap buy, starting at about £60. Vanity unit mounted basins are the luxury ones here. You’ll have to buy the vanity unit as well, but the basin costs at least £100. You also have a choice of material. The cheapest is ceramic, while, stainless steel, glass or polished stone can cost more than £300. A plumber will take 1 to 2 hours to install a basin. 

  • Low end: £50 
  • Midrange: £100 to £300 
  • Luxury: At least £300 

Taps 

Many people don’t realise that taps and other accessories are usually extra and cost more on top of the initial price.  

You can choose from wall mounted taps, those fitted to the basin and taps installed into a vanity unit’s worktop. Additionally, there are also mixer taps or separate pillar hot and cold sets. Pillars are the cheapest at about £30 per set.  Mixer taps come as ‘monobloc’ costing from £50 to £100. Alternatively, cheaper mixer taps start at about £50. There are also various architectural styles and different materials to suit your décor. A set of taps will take about 1 to 2 hours to install. 

  • Low end: £30 
  • Midrange: £40 to £70 
  • Luxury: £50 to at least £100

Tiling 

A bathroom wouldn’t be complete without some waterproof tiling. But, surprisingly tiles are often forgotten when calculating costs in bathroom refurbishment. 

It’s not only tiles either. There’s also grout, adhesive and any backing material behind the tiles on uneven walls or floors. 

Cheap floor tiles, including accessories, cost about £25 per m2, while top-end tiles cost about £70 per m2. A professional wall tiler will take between 1 to 5 days to install wall tiles. 

Floor tiles are more expensive than wall tiles, or you can choose a vinyl floor covering. 

  • Low end: £25 per m2 
  • Midrange: £35 to £50 per m2 
  • Luxury: At least £50 per m2

Additional Components & Labour Day Rates

The labour costs for the individual bathroom components will be less if the plumber installs more than one item at the same time. Most plumbers will take about 3 days to install a complete bathroom suite. But, this will depend on the size of the bathroom and the style and number of fittings you choose. 

A plumber will charge about £300 per day for fitting a complete bathroom and for an averagesized, midrange bathroom, prepare to pay about £1,000 for the fittings. 

You’ll also have to budget for any structural changes to the room and installing any additional plumbing. 

Of course, you might be able to re-use components from your existing bathroom and incorporate them into the new design. If you look around at budget DIY stores, you can often find very attractive and serviceable bathroom suites, incorporating all the components, costing a lot less than the cost of individual items. 

It’s possible to make a luxury bathroom using cheaper components. Buy budget range ceramic units, but choose luxury range trimmings like taps and the shower cubicle. These items always stand out so spend your money on these.  

Remember that prices will vary depending on where in the country you live in. London and the Southeast will cost about 20% more than elsewhere.

Further Considerations

When renovating your bathroom, remember the electrical work. These include electric showers, extractor fans, razor powerpoints, vanity lighting and main lighting, and will always be needed. Additionally, if you choose a luxury spa bath you’ll need an electrical hook-up for the pump. Part P of the Building Regulations clearly states the rules about this, and you should always use a qualified electrician who knows the regulations and can self certify 

You’ll also need a waste skip to remove old fittings. However, expect the plumber to remove any waste copper or brass for recycling.

Planning Permission & Building Regulations 

Generally, you won’t need Planning Permission for a bathroom renovation project unless you are building an extension of a loft conversion. Furthermore, if you own a listed building you should contact the planning department to check if there are any constraints you must comply with. 

On the other hand, the Building Regulations are relevant.  New drainage work and any electrical fitments will need approval. If you are installing a bathroom in a room that previously was not used for this purpose, you must ensure adequate ventilation and proper drainage. You must also comply with Part P which deals with electrical safety, and Part B for fire safety. 

Top 5 Bathroom Fitting Hiring Tips 

  1. Weed out those professionals who give quotations that are too high or too low. If the quote is too high, then the professional is good and is stacked out with work. He doesn’t really want your job so is submitting a silly price. The low quotation comes from the guy who hasn‘t got any work at all. He’s desperate to get work because he isn’t very good at his job. 
  2. You shouldn’t hire anyone whose work you haven’t seenAfter weeding out the extremes, ask for references from the bathroom fitter and contact the people. Then, ask to see the finished work and ask them detailed questions. 
  3. Does the fitter live locally and how long has he been trading? You can tell a lot from these two questions. If he lives locally, then he’s nearby in case anything goes wrong. If he’s been trading a long time, he has the experience and the contacts to do a good job. 
  4. Check for insurance. He should have insurance to cover you and your property from poor workmanship and accidents. 
  5. Check he has the relevant qualifications and certifications for plumbing and electrical work. Or, he intends using a subcontractor for one of these. If the local authority has approved him to self certify his work with regards to the Building Regulation, you can be sure he is a reputable tradesman.

Do you tile before or after fitting a bathroom?

How much will it cost to turn a bedroom into a bathroom? 

You must route plumbing and drainage to and from the new bathroom, so it’s better if you choose a bedroom not too far away from the existing services. Preferably in the next room or above a kitchen or downstairs toilet. If everything goes okay, you can expect to pay between £3,000 and £5,000. Remember that this work will be subject to Building Regulations, so use a good plumber who can provide a Building Regs certificate.
