Bathroom installation cost guide

Updating your home by installing a new bathroom suite is one of the most popular home renovations in the UK. In this guide we’ve put together the average costs for a new bathroom installation, to help you plan the budget for your bathroom project.

Whether you’re renovating, modernising, extending or adding an en-suite, a new bathroom can be a worthy investment for your home. And one that can both improve day-to-day living and add value to the property – if done right.

Doing the work yourself might keep initial costs down, but fitting a new bathroom can be complex. Hiring a bathroom installation expert might be more expensive but in many cases it’s a cost worth paying for, due to the skills needed to successfully install all the different bathroom elements.

We spoke to the online estimators at My Build Estimate – a professional estimating company monitored by the Royal Institute of Chartered Surveyors (RICS). They’ve provided us with estimated average prices for fitting a new low/medium end bathroom suite.

How much does it cost to fit a bathroom?

Bathroom installation costAverage cost range - LowAverage cost range - Medium Average prices
Cost of bathroom renovation (including materials)£1,500£7,500£3,500
Toilet installation£100£175£150
Basin installation£100£200£175
Bath installation£250£400£350
Shower installation£350£600£500
Shower enclosure installation£350£500£400
Heated towel rail installation£200£300£250
Radiator installation£200£300£250

An average low/medium end bathroom installation will cost between £1,500 – £7,500 (including materials).

In this guide we’ve provided a range of costs for low/medium end projects. Generally there’s no average upper limit, as some bathroom/ensuite elements can be considerably more expensive.

Installation of luxury and/or bespoke bathroom fixtures and fittings can cost a lot more than the prices we’ve included.

Things to consider when installing a new bathroom

As with all home improvement projects, there are usually a number of factors that will affect the price you pay. With bathroom installations this is particularly true, as there are so many different types and sizes of bathrooms, all with different elements that directly affect the overall cost.

The majority of your new bathroom installation costs will be affected by:

  • Any electrical work that needs doing
  • Plumbing work (and access to plumbing)
  • The choice of bathroom suite (bath/shower, sink and toilet)
  • Size
  • Location
  • Age and condition of the property
  • If specialists are required (for more complex installations)

How much does it cost to install a new bathroom suite?

Bathroom installation cost

When planning your bathroom installation, it can often be broken down into the different elements. Having a bath and shower will be more expensive than just having one or the other.

Equally, if you only plan to install or replace parts of a bathroom that will keep the cost down.

Bath installation

There are a wide variety of baths to choose from, some fitted and others stand alone. On average, a standard bath installation will cost around £350.

Here’s more information on the cost to install a bath tub.

Shower installation

Depending on the type of shower you choose for you home, it will cost in the region of £500 for supply and installation. The price is affected by the cost of the shower unit itself and the labour involved.

Check out our guide on the cost of a shower install.

Shower enclosure installation

The biggest factors affecting the cost of installing a shower enclosure are the size and the materials used. Larger showers involve more labour. And bespoke designs are often more complex to make and install, which means a higher price tag.

Supply and installation of an average shower enclosure costs about £400.

Basin installation

One of the must-haves in every bathroom, and often in multiples for larger bathrooms where homeowners wanted matching basins for a couple.

For a single basin installation, you’ll be looking at paying around £175.

Toilet installation

The type of toilet unit you choose will be the biggest determining factor of the total price of installing a toilet. Not only for the price of the unit, but also the labour that will be involved – as some toilet systems can be more complex to plumb in than others.

A standard toilet installation will cost you around £150.

Heated towel rail installation

Towel rails have become an integral part of many modern bathrooms, and come in a range of sizes, shapes and styles. An average heated towel rail will cost you about £250.

Radiator installation

As with many other bathroom elements, the type and size will greatly affect the price you pay for to install a new radiator. On average, the cost of a standard radiator installation is about £250.

How long does it take to install a bathroom?

A standard bathroom installation will usually take between 5-10 days. However, this will be affected by the size and complexity of the bathroom.

Other costs to considerBathroom installation prices

In addition to the main bathroom suite itself (bath/shower, sink and toilet), there are a number of other costs to consider for your new bathroom installation. They include:

  • Waste removal
  • Extractor fans
  • Ceiling lights
  • Tiling
  • Pipework adjustments
  • Flooring
  • Finishing
  • Underfloor heating

Can I install my bathroom myself?

If you’re an accomplished DIY enthusiast with experience dealing with complex home improvement projects then you might want to attempt to install your new bathroom yourself.

To install a bathroom you’ll need to be confident dealing with electrics, plumbing, tiling, painting and decorating. Otherwise, we would highly recommend hiring a professional bathroom fitter to carry out the installation work.
