Bathroom Renovation Costs

The cost of your bathroom renovation depends on these factors

Our shower panel comes in an array of colours and design choices that you can choose from to get your dream shower. We stock a range of this type of cladding, but if you can’t find what you are looking for, you can use our bathroom wall panels. They aren’t as thick, strong or wide, but there are more designs to choose from.

Bathroom Renovation
1.The size of your bathroom

Large-sized bathrooms provide more space. However, you’ll need more fitting and fixtures to fill in those space, and it will require a bigger budget.

2.The structural changes that are required

Having significant structural changes such as the installation of skylights, new windows, transferring plumbing or electrical points and replastering walls can add considerable value to the overall cost.

3. The quality of materials and fittings used


There’s a wide variety of options for bathroom fittings and choosing products with higher quality comes at a price.

4. The look you want to achieve.

Those who have a smaller budget can polish, clean and upgrade their fittings. However, removing tiles would cause waterproofing issues. Thus, it requires a full renovation. Meanwhile, those with a bigger budget can add premium fittings and other luxurious elements.

Plumbing Installation

Prices and Labour

Whether you’re able to do it yourself, or need to use professionals, planning the plumbing layout for your bathroom renovation can help reduce costs.

It’s always a good idea to use the existing plumbing wherever possible. Moving the toilet, for example, can escalate your bathroom renovation cost more you might think. Removing a current water supply and drain pipes is labour intensive and will entail quite a lot of breaking into walls and even floors. The same can be said for showers, basins, and baths.

There is no set price regarding the plumbing requirements for a bathroom renovation. It depends entirely on the amount of piping that needs to be installed and the labour requirements. Steel or copper pipe prices in the UK range from about £2.60 for the cheapest copper pipe, up to £6.70 for expensive galvanised pipes. Plastic tubes are popular, these days, as they are by far the most affordable option and uPVC doesn’t rot regardless of chemicals. If there are significant alterations to the existing plumbing layout, the cost for plumbing services can mount from £700 to £900.

Electrical costs

rewiring and diagnostics

The price for electrical wiring alterations can be kept to a minimum, depending mostly on the fixtures that you choose. A luxury bath or shower can require additional electrical wiring if they use a pump. There are worth considering when calculating the electric cost for a bathroom renovation.

Bathroom Fittings and Fixtures

How much does a bath cost?

The cheapest bath can cost as little as £80. Though these will be lightweight acrylic baths, with no reinforcing, a standard acrylic bath will require a frame which will need tiling or some form of waterproof cladding, so this cost needs to be taken into account. High-end, freestanding acrylic baths are strong and durable. These cost anything from £250 to over £1500.

An economy steel bath is probably the best value for money. They are of a reasonable quality standard and can cost as little as £120. If you have the budget for the ultimate in luxury baths, cast iron and stone baths will be the most expensive. Typical bath installation can take 3 to 4 hours.

Bath Cost Summary:

How much does a shower cost?

The cheapest option would be an electric shower, and this can be as little as £50. These showerheads only require a cold water supply, and the water then heated at the shower unit. They need an electric connection but use very little power. It will save on electricity costs over time, though the cheapest electric showers are not always that effective at heating the water properly.

Combination bath and shower mixers are also a cheap option and don’t require a shower enclosure. These also range from about £50 and upwards.

A standard shower mixer will cost you around £60 for a basic unit. A Thermostatic shower mixer adjusts the water temperature when the water pressure changes and these cost upwards of £125.

Luxury showers come in various forms. A power shower uses a booster pump to increase the water pressure and will cost upwards of £150. Digital showers have settings for water pulsing, along with various jets and sprays. These will cost £250 or more.

You will also need to consider the cost of the shower enclosure. These usually come in kits that include the shower tray, frame and door. An economy quadrant tray and a frameless door can cost as little as £60, with full wet room kits exceeding £500. Fixing shower into your walls can take 1 to 2 hours.

Shower Cost Summary:

How much does a bathroom basin cost?

Depending on the style you’re going for, you can choose between pedestal, semi-pedestal, or vanity unit basins. The budget option would be a ceramic pedestal basin, with prices starting at around £50. For a little more, a basic semi-pedestal (wall-hung) bowl can be a cost-effective solution, the cheapest of which is about £60.

Vanity units are the most elegant, and most expensive. Apart from the cost of building the actual group, the basin is going to cost you £90 or more. Standard ceramic bowls will always be the cheapest. The more elite metal, glass, or stone basins can end up costing over £300, and installation can take around 1 to 2 hours.

Bathroom Basin Cost Summary:

How Much does a toilet cost?

If you’re considering a standard floor-mounted toilet, you’ll only be paying about £50. If you’d prefer a more elegant design, expect to pay up to £500. Usually, the installation of a toilet takes 2 to 3 hours.

Toilet Cost Summary:

How much do taps cost?


You have three basic options for bathroom taps. You also need to take into account the type of basin or bath that you choose. Some sinks and tubs will require wall-mounted faucets, whereas many countertop basins will need a tap that’s mounted to the counter. A freestanding bath, far from a wall, will need floor-mounted taps. You can usually get the job done within 2 hours while skilled workers can do it quicker.

Pillar taps are separate units (one cold and one hot) and are the cheapest, from £30 for a set. Mixer taps come in two variations.

The more expensive, more convenient option, is the Monobloc mixer. These taps have a single handle that you lift to open and swivel to either side for water temperature control. Monobloc mixers cost £50 to a little over £100. Cheaper water mixers (from about £45) have separate controls for hot and cold water.

Bathroom Walls

Tiling and other Cladding Alternative

How much does it cost to tile a bathroom?

Bathroom tiles or wall cladding makes a considerable difference to the look and practicality of the bathroom. When estimating the cost of tiling your bathroom, you need to also factor in the value of the tile adhesive, grouting, and the ply underneath floor tiles.

Budget floor tiles (including adhesive, grouting, and ply) should cost about £25 per square meter. For mid-range floor tiles, you’ll be paying about double this, while top-end tiles can cost up to £65 per square meter. Installation takes 1 to 5 days, depending on the coverage required.

Tile Cost Summary:

Wall tiles are usually a little cheaper than floor tiles, but there is a much less expensive option which is the Vinyl flooring. PVC wall panels are rapidly becoming the wall cladding of choice for bathroom renovations in the UK. Not only are they cheaper to buy, but they are also much easier to install. It reduces your building cost and saves a lot of time. It’s the most cost-effective solution and is very elegant. These waterproof wall panels are available at Easypanels for as low as £9.50 (250mm x 2600mm). So, it’s an excellent cladding solution if you’re working on a budget and the installation can be done within 1 to 3 days.

What are the labour costs for a bathroom renovation?

Most plumbers will complete a bathroom renovation in about two to three days. It will depend on the size of your bathroom and the amount of work required. Our labour estimator for a bathroom renovation won’t be the same throughout the UK. On average, one can expect to pay around £350 per day for labour. For an average-sized bathroom, you should budget approximately £1000 for the actual plumbing.

Planning Your Bathroom Renovation

The typical bathroom renovation order of work sets out the steps and procedures that one should follow. It helps to know what you’re in for, especially if you’re planning your first DIY bathroom renovation. A professional bathroom renovation team will work according to a well laid out schedule to maximise efficiency and reduce the disruption to your home. Even if you use a contractor, you may be able to save some money on the initial preparation by doing it yourself.

Planning Your Bathroom Renovation


Step 1: Initial Preparation

Remove all personal effects from the bathroom. Turn the main water supply off and drain the central heating system. Lay down floor protection for all areas leading to the bathroom. All bathroom fixtures are removed. Redundant electric wiring and pipes are removed. Tiles are stripped and the walls repaired and prepared for new cladding.

Step 2: Plumbing and wiring

Walls will need to be chased for the installation of new pipes and electrical wiring. Holes in the floor and walls are drilled where required. Electric wiring and pipes need to be installed according to council regulations.

Step 3: Building and Preparation

Any structural changes need to accommodate the bath, vanity counters or basins, the toilet, and shower enclosure required to be completed. The walls need to be plastered and prepared for tiling. All fixtures are secured to the floor or walls.

Step 4: Tiling

Before tiling, all surfaces need to be cleaned, leaving no trace of loose grit. Wooden floors need a waterproof floor ply. Depending on the weather, tiling will typically take about two days. The tile adhesive needs to set, before grouting. Alternative wall cladding, like PVC wall panels, should only take a couple of hours to install.

Step 5: Finishing and Cleaning

Wall-mounted taps, towel rails and shelves can only be installed after the wall cladding has been fitted and cleaned. After that, all remaining cleaning can be done. Cleaning grout residue can take some time.

As you can see, there is a lot of planning that goes into a bathroom renovation. Doing your homework will make a big difference, both in the bathroom renovation cost, and how smoothly the project runs. Shopping around for good deals and requesting several quotes from plumbers is advisable, though plumbers with proper references can put your mind at ease, even if they aren’t the cheapest. So it’s not entirely about the cost, you need to know that you’re spending your money wisely.
