Bathroom Design & Installation

Cost of bathroom installation

Whether you are replacing a few items or want a full bathroom renovation, working with an experienced fitter can make the whole process simple.

A great bathroom fitter will be able to design a bathroom that is top quality, saves on space and looks excellent. They will be able to help source and fit your new suite, carry out tiling or plastering, and install any extras, too.

In fact, working with a professional fitter is the best way to achieve a high standard bathroom without having to pay inflated costs.

Depending on how much work your bathroom needs, your final fee may vary, especially if you want a whole new suite. If you are wondering how much it costs to install a new bathroom, this guide is here to help you.

We have put together everything you need to know about different bathroom installation rates, including the cost of individual jobs. We have also got details on how much it will cost to plaster and tile your new space, as well as the average time it takes to complete each task.

Bathroom installation cost guide

Depending on the bathroom work you have in mind, your fitter will either charge you per hour or per square metre. If you are having a suite installed, this will be factored into the cost so the more items you want replaced, the higher your total cost will be.

If you just want a new sink installed, many fitters will be able to give you a standard quote for the job without seeing the bathroom first. For a full bathroom redesign or more complicated projects, like creating a basement bathroom, they will probably schedule a few appointments with you in order to look at the space and get your opinion on different designs.

Most people will not need their bathroom fully refitted in an emergency but if you need an urgent shower or toilet installation, you will have to pay a higher rate. Keep in mind that the model of suite you choose can also boost your final fee. If you are based in London or the South East, expect to pay slightly higher costs.

Standard bathroom design rates

There are so many different jobs involved in a bathroom redesign that it can be hard to know what fees to expect. Here is a handy breakdown of how your bathroom fitter may charge you, and which costs you will need to budget for:

Hourly rates

If you are employing a bathroom fitter for a minor job that can be completed in under a day, you will probably be charged per hour.

For example, installing a new fan or bathroom lights will only take a few hours so you are unlikely to be charged a daily rate. A new light takes 2 hours to install and usually costs around £155, which is a rate of £77.50 per hour.

Keep in mind your fitter will include the cost of any new fittings in their hourly rate so the more items you have installed, the higher your final fee will be. Smaller items, like extractor fans, will cost about £60 but your fitter may be able to source more affordable fittings for you.

Daily rates

If you are planning a full bathroom redesign, your fitter will charge you a daily rate for the length of the project.

For example, installing underfloor heating can take 1.5 days and will often need to be completed before the rest of your renovation work. The cost of this work is in the region of £275, so the rate per day is £183.

If your bathroom fitter works with a team, your project will take less time to complete, meaning you will be charged for fewer days of work.

Materials costs

For a full bathroom renovation, your fitter will discuss the different styles of bathroom furniture with you and make recommendations for the space. If you buy your new suite through your fitter, this cost will be included in your final fee but they will often give you a few options to suit different price points.

Replacing some of your bathroom furniture will cost less than a whole new suite. However, for complete renovations, you can often save money by buying everything from one supplier, instead of purchasing each piece individually. For example, some cost-effective suites can start from £300 but purchasing a toilet individually can cost £150 for a standard model.

The general cost of a standard suite will be in the region of £1,200 but the design and quality can affect the final price.

If you are unsure, always discuss your options with your fitter. They will have a lot of experience in working with different budgets and will be able to give you personalised advice.

Full bathroom installation costs

Once you have a quote for a daily rate and you have chosen your bathroom fittings, you may be wondering how much it will cost for a full bathroom installation.

For a standard bathroom installation that includes tiling, plastering and a new suite, it will cost around £4,600.

The final fee may be affected by your location, the size of your bathroom and the fittings you choose. If your renovation runs into any issues, you might have to pay more than your original quote but this should not be more than 10% extra.

Some bathroom renovations will be naturally more affordable. For example, the cost to install an en suite or downstairs bathroom will often be less as they are usually smaller rooms and require less furniture or tiling work.

Generally, a downstairs bathroom will cost £2,000 to install but this can be cheaper if you are simply renovating an existing bathroom. To install an upstairs bathroom, expect to pay £3,500.

For more complex renovations, you will have to pay a higher fee. To install a bathroom in a basement, expect to pay around £7,000 but this can be as much as £11,000 if you need to extend your basement space or fit a new plumbing system.

Average labour costs to install a new bathroom

If you are wondering how much each stage of your bathroom design project will cost, here is a breakdown of the different services your fitter will offer, and how much you can expect to pay for them.

Suite removal

If you are planning a big project, keep in mind that you will have to pay for the removal of your old bathroom fittings. This job should not take more than 2 days and cost around £400.

If you are keeping some of your bathroom fittings, this will reduce the amount of time it takes to prepare the room for the new suite so you will save on daily rates.

Toilet installation

If you are simply replacing an old toilet, installing the new model should only take 2 hours and cost about £335.

Depending on the quality of toilet you choose, you may have to spend more but you can generally find discounts when you buy a whole suite at once.

You might also have to pay more if your bathroom fitter discovers any damage after removing the old unit but fixing the problem now will save you time and money in the long run.

Shower installation

Any shower installation times or costs will depend on your chosen model.

For a standalone cubicle installation, the work can usually be completed in 4 hours at a cost in the region of £515. If you are installing a brand new mixer shower, the work can take around 5 hours and will cost around £363.

It is worth considering replacing your old shower with a newer version of the same model as this can make it easier to fit, and cut installation time to about 2 hours.

Sink installation

A sink installation will be one of the quickest parts of your bathroom renovation. Sinks take 1.5 hours to fit and cost around £335.

A higher quality sink unit will come with a bigger cost and keep in mind that repairing any water damage from old leaky taps will also boost your final fee.

Bath installation

Replacing your bath will take 4 hours of labour and cost around £375. Standalone baths will require less time to fit but built-in units can be more complicated, and cost slightly more to install.

If you are trying to save on space, your bathroom fitter might recommend you opt for a smaller bath or a combined bath and shower. These models are generally much cheaper and can be easier for your fitter to install, too.

Fan installation

If you are trying to avoid water damage, a good quality extractor fan is a must. Installation takes around 3 hours and you can expect to pay in the region of £170.

Keep in mind that installing a whole new fan system will be more complicated, especially for upstairs bathrooms, and rates can start at £300.


Your bathroom designer will often charge per square metre for tiling jobs so the bigger your space, the more your final cost will be.

Generally, the cost is £80 per square metre and a standard size bathroom can be completed in 3 days. If your bathroom has alcoves or a complex shape, this will count towards the overall tiling area and boost your final fee.

A more cost-effective option can be to tile just half of the wall or only around places that will be exposed to more water. This way, you will save money on the tiles and will pay less on installation costs, too.


In some cases, you might need to completely re-plaster your bathroom as part of the renovation process. This is especially important if your bathroom has a lot of water damage or if the old plaster has started to crack. New plaster can make it easier to apply tiles and paint, and will make the entire space more waterproof so it is definitely worth the investment.

As with tiling, your fitter will probably charge you per square metre. Plastering can usually be completed in 2 days and will cost around £65 per square metre.

Smaller areas, like a downstairs bathroom, can take less than a day’s work so they will work out cheaper overall.

Keep in mind that your plaster will need to be fully dry before the rest of your renovation can begin so you may have to wait a short while once all the plastering is completed.

3 tips to finding the right bathroom fitter

If you are unsure which bathroom fitter to work with, here are 3 simple tips to help you make sure you have selected the best service for your design needs:

Ask about experience

Making sure your fitter has the right experience is essential, especially if you are looking for a specialised service, like a basement bathroom installation.

The easiest way to double-check your fitter’s experience is to read online customer reviews. This way, you can get an idea of which projects they have worked on in the past and can look for businesses that are punctual as well as professional.

If you have a friend or family member who has recently renovated their bathroom, it is a good idea to ask them for their recommendations. They will be able to give you in-depth information about their experience and might let you take a look at their finished bathroom.

Be clear on payment

To avoid getting caught out, it is important to opt for a bathroom fitter who is clear about their rates. A fitter who itemises their costs for you is less likely to hit you with hidden charges so make sure you know exactly how much you will pay, and what that money is going towards.

It is also a good idea to agree on a payment plan with your fitter as this makes it easier to budget for each payment.

Finally, always ask for a second opinion. Getting quotes from a few different bathroom designers will help you understand the average rates in your area, and make it easier to choose the best deal.

Check their certifications

Always remember to double-check your bathroom fitter is fully certified before they begin work.

This is especially important if your fitter will be completing your entire bathroom installation. For example, if your fitter is installing your new suite and taking on your plastering and tiling, you should make sure they are qualified for all 3 of these jobs.

Any fitter who is a member of a professional organisation will be more highly regulated and will have to follow certain guidelines. This can certainly give you peace of mind.
