How Much Should I Charge to Fit a Bathroom?

For bathroom installers

There isn't one figure I can give you and say, “That is what you should charge to fit a bathroom.”

You can find plenty of bathroom fitter day rates and average installation prices online, but somebody else's figure doesn't tell you what your business needs to charge, and it certainly doesn't tell you what the bathroom in front of you is going to take to complete properly.

A straightforward replacement bathroom, with the new sanitaryware going back in roughly the same positions, is a completely different job from moving the toilet, altering drainage, changing the shower position, preparing poor walls, replacing damaged flooring, tanking wet areas, tiling the whole room and coordinating several different trades.

They might both be described by the customer as “fitting a bathroom”. They are not the same job.

Start with the bathroom in front of you, not somebody else's day rate

I've never been a fan of deciding what to charge because somebody down the road charges £250, £300 or £400 a day. You don't know their overheads. You don't know what they include, what they leave out, whether they are VAT registered, whether they use subbies, how much non-productive time they carry or, most importantly, whether they are actually making any money. Your price has to work for your business.

With a bathroom, that starts with understanding the complete project. Depending on the job, you may be pricing for strip-out and waste removal, plumbing and drainage alterations, first fix, wall and floor preparation, waterproofing, tiling, sanitaryware, shower or bath installation, ventilation, electrical work, sealing, finishing, testing and the time involved in managing other trades.

Then there are all the smaller things that still take time and cost money: collecting materials, protecting the customer's home, parking, disposal, deliveries, fixing problems with customer-supplied products and returning to complete something that could not be finished because another part of the job was delayed.

Leave enough of those things out, and a bathroom that looked profitable when you quoted it can become a very different job by the time you finish.

A like-for-like bathroom is not the same as changing the whole layout

Where everything is staying in roughly the same place and you know the condition of the room, you may be able to price the installation with a reasonable amount of confidence.

Move the toilet and suddenly the soil connection matters. Move a basin or shower and water supplies and wastes may need changing. Take tiles off and the walls behind them may be perfectly sound — very occasionally — or you may discover they need considerably more preparation than expected.

Bathrooms also have a habit of hiding problems until the old room comes out. Rotten flooring around an old shower or toilet, previous leaks, poor plumbing, damaged plasterboard and questionable work from earlier installations are all things many of us have uncovered over the years. If there has been water around a bath, shower or toilet for years, you need to be realistic about the possibility that there may be damage you cannot see during the survey.

Water also does not always make the problem obvious. A leak can start in one place, appear somewhere completely different and cause damage along the way. Anyone who has had to trace one knows how quickly a small-looking problem can turn into a time-consuming one.

That does not mean you should throw a huge contingency into every bathroom price just in case something goes wrong. It means your quote needs to make clear what you have priced, what you could reasonably inspect beforehand and how genuinely hidden additional work will be dealt with if it appears.

A mistake in your original pricing is not automatically a variation. But something you genuinely could not have known about before opening the room up can be.

Bathrooms are not a job to rush

This is one of the biggest things I learned from fitting bathrooms. You are dealing with water for a large part of the job, and mistakes have a habit of biting you later. Trying to force the programme or shave too much time off a bathroom can create exactly the sort of problems you were trying to avoid.

There are times when slowing down is the quickest way to finish the job properly.

A shower tray is a good example. In many installations it effectively becomes a first-fix item. Once it is fitted, tiled around, sealed and the rest of the bathroom is completed, it is one of the last things you ever want to have to remove again.

That means fitting it properly matters, but protecting it afterwards matters as well. If it gets scratched or damaged while the rest of the bathroom is being completed, replacing it can mean disturbing finished tiling and undoing work that has already been completed.

The same applies throughout a bathroom. Take the time to test things properly, protect finished products and make sure each stage is right before covering it up or moving on.

If your price is so tight that the only way to make money is to rush the installation, I would question whether the job has been priced properly in the first place. Trying to be the cheapest bathroom fitter is not much comfort when you are going back months later trying to trace a leak.

Work out what the job needs to earn

Once you understand the scope, you still need to know what your own time is worth.

Your working rate has to contribute towards more than the hours you physically spend fitting. A self-employed installer still has a van, fuel, tools, insurance, accountancy, phones, software, workwear, quoting, surveys, admin, holidays, sickness and all the other costs that come with running a business.

You also need to make a profit. That sounds obvious, but plenty of very busy installers end up paying themselves for doing the work without properly charging for the business that sits around it.

If you employ people or use subcontractors, their cost needs to be properly understood too. What you pay somebody is not automatically what you should charge the customer for their involvement. There is still organisation, responsibility, risk and often your own time managing that part of the project.

This is why copying an online bathroom fitter day rate is such a poor starting point. The number might be useful as a bit of market context, but it cannot tell you what your bathroom installation business needs to earn.

Price the complete job, not just the days you think you will be fitting

I generally like a properly worked-out fixed price where the scope is clear enough to price with confidence. The customer is buying a finished bathroom installation, not simply buying eight or ten days of your life.

Experience also has value. If you can complete something properly in six days that might take somebody else eight, I don't believe becoming better and more efficient should automatically mean earning less.

But there is an important distinction between being efficient and rushing. Efficiency comes from experience, better organisation, having the right tools and knowing the order in which things need to happen. Rushing is trying to squeeze eight days of work into six because the price wasn't high enough in the first place. Bathrooms are not forgiving of that.

That doesn't mean you ignore time when pricing. Far from it. You need a realistic idea of how long every stage will take because your time is one of the main costs inside the job. The difference is that your time becomes part of the calculation behind your price rather than necessarily being the product you sell to the customer.

There will still be bathroom work where a day rate makes more sense. Investigation work, repairs, opening up areas where nobody knows what will be found or other genuinely uncertain work can be difficult to fix-price fairly.

Use the method that suits the risk you are taking on rather than deciding that every bathroom must always be priced in exactly the same way.

Don't forget who is managing the job

One of the areas that gets missed in bathroom pricing is project management. If you are bringing in an electrician, tiler, plasterer, plumber or another specialist, somebody still needs to organise when they arrive, make sure the room is ready for them and deal with the knock-on effect if the programme changes. If you are the person taking responsibility for delivering the complete bathroom, that responsibility has value.

Over the years I came to realise something else as well. When it is your job and your customer, nobody involved in that project is likely to care about the finished result quite as much as you do.

That isn't a criticism of good subcontractors. A good electrician, tiler or plasterer can be worth their weight in gold. But they may be doing one part of your bathroom before moving on to another job. You are the person who has to hand the finished room over to the customer and you are normally the person the customer phones if something is wrong.

That means you have to stay on top of the project. You need to make sure the trades you use are good enough, that they understand what is expected, that their work fits with what comes next and that you have allowed enough money to use the right people rather than simply looking for the cheapest subcontractor you can find.

Cutting corners on the people involved can become very expensive if you end up putting their work right afterwards.

The customer could potentially organise a plumber, tiler, electrician and other trades separately themselves. If they are paying you to take the whole installation from strip-out to completion and coordinate everybody involved, don't treat that work as if it costs you nothing.

At the same time, be clear about what you are actually taking responsibility for. Being the main bathroom fitter does not mean pretending you are competent to undertake every specialist part of the project yourself.

Customer-supplied products can change the job too

A labour-only bathroom where the customer supplies everything can look simpler to price because you are not buying the sanitaryware, tiles and fittings. It can still create cost and risk.

Products arrive damaged. Parts are missing. Cheap fittings take longer to install. Shower trays don't match what was measured. Concealed components turn up without the pieces needed to complete the installation. Tiles can be short or unsuitable for what has been planned.

Some products also deserve more thought simply because of where they sit in the finished bathroom. Again, a shower tray is a good example. A tap or even a toilet can generally be replaced later without dismantling half the room. Replacing a shower tray once walls and floors have been tiled around it can be a completely different exercise. That is worth thinking about when products are being specified and when you are deciding how much care and protection they need during the installation.

You cannot prevent every product problem, but your quote can explain what you have assumed will be available and suitable when you arrive and what happens if customer-supplied products cause additional work or delay. Again, that is not about looking for extras. It is about making the job clear before you start.

The customer needs a clear scope, not your internal costing sheet

There is a difference between giving a customer a clear quotation and showing them every internal calculation you have used to reach your price. The customer needs to know what you are doing, what you are not doing, the agreed price, the main assumptions, who is supplying what and how additional work will be handled. They do not automatically need your internal labour allowances, overhead calculations, buying prices or profit margin.

If the customer removes part of the work, you may also need to reprice the revised bathroom rather than simply subtracting one figure from the original quote. Installation is a sequence of connected work and changing one part can affect other stages of the job.

Look back at completed bathrooms

One of the best ways to improve bathroom pricing is to stop treating every completed job as finished and forgotten. Look at what you allowed and compare it with what actually happened.

How long did the strip-out take? How much preparation was needed? Did the tiling take what you expected? Did you spend more time organising other trades than you allowed? Were there materials or small costs you repeatedly forgot?

Also look at the problems. Were there stages where you felt rushed? Did a subcontractor cause a delay? Did you have to go back because something had not been tested properly? Did you spend time protecting or replacing something you had not allowed for?

Those lessons matter because bathrooms have a way of reminding you about shortcuts long after the original job has finished.

Over a number of installations, that information becomes far more useful than an online article telling you the national average bathroom fitter day rate. You start building your own evidence. That is how pricing becomes more accurate.

So, how much should you charge to fit a bathroom?

Charge enough to complete the bathroom properly, cover every cost involved in providing the installation, pay yourself properly and leave a worthwhile profit for the business.

Build the price from the actual scope in front of you. Understand the difference between a simple replacement and a complete reconfiguration. Be realistic about the possibility of hidden damage. Allow properly for preparation, specialist trades and the time involved in coordinating the job.

Most importantly, allow enough time to do the work properly. Bathrooms are one of those jobs where cutting a corner today can come back to find you months later. Water gets into places you didn't expect, a small leak can cause damage somewhere else and products that are easy to fit during the installation can be extremely difficult to replace once everything around them is finished.

Protect yourself against genuine unknowns with a clear scope and variation process rather than trying to guess every possible problem beforehand.

And use market rates as context, not as your business plan.

You are not trying to discover what every other bathroom fitter charges. You are trying to work out what you need to charge for this bathroom to do the job properly and for the job to be worthwhile.
