How Much Is a New Bathroom?

How much does a new bathroom cost in the UK?

The average cost of a medium-sized bathroom with an average finish is £5,000. The size of your bathroom and the quality of the finish you are after will significantly impact the overall cost of your bathroom refurbishment.

Obviously, the larger your bathroom, the more work will be required - but, if you have an awkward bathroom layout, this will also impact your costs. Although new bathroom suites will account for a large portion of your project's budget, labour costs can be the highest cost of a new bathroom.

Other central factors that can influence the cost of a complete bathroom refurbishment can include:

If you need to have your bathroom redesigned to change the use of your bathroom.
If you're changing the shape or size of your bathroom.
If you're making a room that was not a bathroom previously into an additional bathroom for your home.

I've just bought my first house and the bathroom needs renovating. No plastering needed, no paint needed, a lino floor, and PVC plastic 4 sheets needed. My cheapest quote was £7,500. Is that how much a bathroom renovation costs?

"I reckon this type of bathroom renovation costs £5,000, but it could be even cheaper depending on how fancy you choose the style and who you get to fit it for you."

How Much to Fit a Bathroom? (Labour Only)

Next, let's look at bathroom fitting labour costs.

Fitting a bathroom takes between 6 and 8 days to complete. Labourers typically charge £100 to £150 per day, totaling £600 to £1,200 in labour costs alone.

However, the type of refurbishment you take on will directly impact the timescale of your project and, therefore, your expected labour costs.

Most bathroom refurbishment projects will need the following tradespeople:

Plumber
Electrician or Heating Technician
Plasterer
Tiler
Carpenter
Floor Fitter

You may also need an additional contractor to redesign your bathroom or reconfigure a space, and a builder if you need to move walls or knock through spaces to create a larger room.

How much does it cost to install a new bath, toilet, and sink in a bathroom?

"I would personally go off a day rate, as it can depend on the pipes. Generally, a plumber would charge £180 to £250 a day. This job could take around 3 to 4 working days."

AA's Maintenance

Cost of Bathroom Removal

The main cost of removing a bathroom is found in waste removal services and labour. A skip will cost between £180 and £300 to hire on average, while a labourer will typically charge between £100 to £150 a day to remove your bathroom.

This price will depend on the size of your existing bathroom suite and whether or not you're selling the suite, as the labourer will have to be more careful with their removal tactics if you need to preserve the old suite.

How Long Does a Bathroom Renovation Take?

The average bathroom takes around 6 to 8 days to complete.

However, the size of your bathroom will have more of an impact on the timescale for completing your full bathroom refurb than the level of finish. The finish is more swayed by the tiles you choose, fixtures, and fittings.

Factors that could increase the length of time it takes to complete your full bathroom refurbishment can include:

Late deliveries of necessary supplies.
Build and manufacture time for custom-built pieces.
Uncovering issues with plumbing, electrics, or walls during the process.

I need my 3m x 3m bathroom renovating. The whole thing needs removing and new bath, sink, and toilet installed along with tiling. How long should I expect it to take?

"Depends on how many men you throw at it, and what the state of the walls are once everything is stripped out. Obviously much quicker with two people, but then you start falling over each other in a small space. It's much easier if you can go away for a week so that the contractor can get the bulk of it done."

What Impacts the Cost of a New Bathroom?

Bathroom Size and Shape

The size and shape of your bathroom will affect your refurbishment cost - the larger your bathroom, the more money it will generally cost.

However, small bathrooms don't always equal lower costs. Bathrooms which are odd in their shape or difficult to work in and therefore require specialist work are labour-intensive and may need bespoke bathroom units to fit in, all of which will increase your project's price.

Room Reconfiguration

If you want to switch up an existing room with no plumbing into a bathroom, be aware that this will cost considerably more than a straightforward old-for-new bathroom suite replacement.

This is because this job will include more work and skill and enlisting the help of additional tradespeople such as electricians, plumbers, and builders to knock down walls, lay pipes, and electrical cables. For example, if you're having a loft conversion with a new bathroom, this can cost in the region of £20,000 and £60,000+.

Quality of Finish

The more basic the items you are looking to include in your new bathroom, the lower the overall cost will be, but you will have to take into account the quality and how long these items will last.

You may think you're getting a good deal by buying the cheapest toilet seat or extractor fan, but if they do not work properly, break frequently, or do not do the job, replacing them could see you spending more money than if you had gone for a better quality item in the first place.

Adding nice-to-have extras such as underfloor heating, LED mood lighting, and waterproof TVs can increase the premium quality of a bathroom refurb - although this comes at a higher price.

Functionality of Bathroom Suite

There are thousands of bathroom suites on the market, which is great news as there is something for everyone, but how specific do you want to be? For some people, price is more important than the style, aesthetic or extra functions that a suite may have.

People short on space often want every piece to be as multi-functional as possible. There are single-unit showers or double units, some with sliding doors or concertina doors, or there are walk-in showers, and even wet rooms, for example.

What Are the Benefits of a New Bathroom?

Adds Value to Your Home

A bathroom refurbishment can increase your property's value by 3% to 5%. Bathrooms, along with kitchens, typically see a return on investment (ROI) of approximately 48% or 49%.

To get the best ROI, you'll want to keep things relatively simple if the only reason you're refurbing your bathroom is to be able to sell your home more easily.

If your bathroom is too personalised for you, it can adversely affect your ability to sell your property. In these scenarios, you should keep the design neutral and plain.

How much will I increase the value of my London home by having my bathroom renovated?

"A new bathroom renovation will not always increase the value of the property a great amount, maybe 20% to 30% of the renovation cost, what it will do is give the estate agent more selling power if you decide to sell."

David Barnard

Improves the Aesthetics

Increasing the overall look of your bathroom will make a huge difference to your day-to-day living. Having a bathroom that you look forward to being in can help the space become a sanctuary.

For some, this can be done with something as simple as a fresh coat of paint. Other people may want to change the fixtures in their existing bathrooms to make them more modern and functional.

Corrects Old Problems or Faults

Your home's bathroom is one of the most-used spaces, making the likelihood of problems and faults occurring high.

There can be different types of issues, such as storage issues or replacing leaking shower pipes, which are relatively simple to remedy. Other jobs may require you to get in contact with a professional, such as a plumber for a leaking toilet or an electrician for a faulty light or broken extractor fan.

Optimises the Space

Many bathrooms can be awkward shapes, with the most common being those in listed buildings, ensuite bathrooms, or bathrooms in attics created as part of a loft conversion project.

Having multi-functional storage solutions in your bathroom can be one way of optimising the space. If you have awkward corners, alcoves, or gaps that you don't know what to do with, hiring a local carpenter can help to transform otherwise unused areas of your bathroom.

Increases the Energy Efficiency of Your Bathroom

With water and electricity both costing a small fortune over a year, it is becoming increasingly common for people, especially within larger households, to look for ways to become more energy-efficient bathroom users.

This can be something as simple as opting to take a shower over having a bath, as the cost of the average shower is approximately a third of the price of a bath. But there are other things that you can do too.

Energy-saving options can be things such as installing a water-saving showerhead, replacing your regular toilet for a low-flow toilet, and getting energy-efficient LED lighting installed.

How to Keep New Bathroom Costs Down

Ask Contractors for Itemised Quotes

When collecting quotes from contractors, you should always ask for an itemised breakdown of costs. Not only does this help with avoiding last-minute price hikes and "forgotten" costs, it will help you see where you could potentially save money.

For example, if your contractor is charging you a premium for new bathroom tiles, shop around and see if you can source them yourself, taking advantage of sale seasons and offers. Being savvy with collecting your supplies can pay off in the long run, although it can be time-consuming.

Choose to Self-Manage Your Project

Not only will this help you stay on top of your project, but it will also prevent you from spending money on hiring someone else to be your project manager.

However, if you work long hours, work away from home, or just don't feel comfortable with the undertaking, this might not be the ideal option, but it can be a great way of saving money if you are comfortable with the responsibility.

Aim for Early Sign-Off

The earlier plans and planning approval are signed off, you will have fewer hold-ups. If keeping to a tight budget is imperative, then signing off early is the way to achieve that.

Find Cheaper Alternatives

If you're looking to keep the cost of your full bathroom refurb down, you should opt for the most basic bathroom suite.

You need to focus more on function than style here, and you can add more personal touches with your finishing, which will be much cheaper than buying an expensive bathroom suite.

Be Savvy with Installations

To cut around 40% off your total tile price, you can tile the areas you need to be made splash-proof - around the bath, shower, and basin - instead of the entire bathroom.

DIY

Depending on the size of your bathroom, this can easily remove a significant amount of labour time and costs for your tradesmen if you feel you want to have a go.

These DIY tasks can include:

Doing any of the labour-intensive jobs yourself, as long as you feel competent enough to undertake them. Tiling is the most popular.
Ordering and collecting your new bathroom suite to avoid delivery costs.
Being your own project manager.

What Does Bathroom Removal Look Like?

While you can undertake some work yourself, such as tile removal, it is advised that you employ professional traders to handle the bulk of the job. Bathrooms combine water and electricity in close proximity and, therefore require professional attention to ensure safety.

Certain elements of a new bathroom installation must be approved by a self-certified installer or the Building Control Authority. To avoid additional costs, having professional labourers undertaking the work for you can make this job much safer and faster than if you were to do it yourself.

Your contractor will first turn off your central heating, and drain the system. If there are any electrical connections in your bathroom, these will be turned off.
The contractor will then remove the old bathroom suite, leaving the bath until last as water and waste will need to be drained into it.
Once all of your suite has been removed, your contractor will then need to remove and replace all waste pipes in your bathroom.
The final job will be to remove all traces of your old bathroom, such as old wall and floor tiles, and clear the waste away into a skip.

Can I Install a New Bathroom Myself?

You can fit a new bathroom or undertake a bathroom refurb as a DIY project if you are experienced in the necessary areas. However, it is advised that you use professional tradesmen to undertake the task. Electricals are dangerous, and when combined with water, the risk is huge.

Getting things wrong when attempting to complete a DIY bathroom refurb may not only be dangerous but also hugely costly, as they often end up with professionals coming in to put right all of the issues that a DIY fanatic has accidentally done incorrectly.

There are, however, some areas of your bathroom refurb that are much easier, safer and often rather fun for you to take on as a project of your own.

The more popular DIY job to be done by amateurs is tiling, grouting and sealing the walls of a bathroom. It’s fairly simple to do once the walls have been made flat, even with the wallboards, and it is a very repetitive job, so once you have been shown what to do, you can soon speed up.

I’m getting a new bathroom fitted. Should I get the floor and walls tiled first, or will they likely get damaged by the fitters?

"You'll need to complete the first fix plumbing work, including water and waste pipes. After that, you can tile the space and then install the hand basin and toilet.

For the bathtub, it depends on the type. You have two options: install the bathtub before tiling or, if it's a freestanding bathtub with exposed legs, tile the floor and walls first, then install the bathtub."

FAQs

How Much Does It Cost to Redo a Bathroom?

The average new bathroom cost is about £7,000.

How Long Does It Take for a New Bathroom to Be Fitted?

On average, it takes 8 to 10 days to fit a new bathroom, but this may vary depending on the size, difficulty of the job and the quality of the overall job required.

What Do You Do With Your Old Bathroom Suite?

Most people simply throw their old bathroom suite into a skip, but some people opt to put certain items on selling sites. They may not gain thousands of pounds back from this, but in a costly refurb such as a bathroom, every little helps!

How Do You Protect New Sockets in a Bathroom?

The only sockets allowed in a UK bathroom are those of shaver sockets. Lights should be enclosed, and no hanging lights should be used.

You can get waterproof sockets for a bathroom, similar to those that can be used outdoors, but it is ill-advised to use any electrical appliance around water and, therefore, in a bathroom, which is one of the most dangerous rooms of the house because the two should never mix.
