Bathroom fitting – what you’re paying for


An experienced bathroom fitter has the skills to transform a dated suite into somewhere you can relax. The cost of refitting a bathroom can vary drastically though. So, whether you’re looking at a full refit or just want to swap out a few elements to spruce things up, use our bathroom fitting cost guide to forecast the potential cost of your project.

Below, we’ve included some things that you’ll want to keep front of mind when choosing your suite. One of the main factors to think about is that certain types of shower, bath, toilet and basin won’t just cost more to buy, they could cost more to install.

There are also accessories and finishing touches to mull over. The sorts of additions you might want included range from options such as underfloor heating and towel radiators through to improvements designed to prevent moisture and condensation problems – like an extractor fan.

How much does it cost to install a bath?


The average cost of installing a bath is £300.

The price of a bath starts at around £100 but it can cost a lot more depending on the material and design. The most affordable bathtubs are made from fibreglass, or FRP (fibreglass-reinforced plastic). It’s a light material that’s easy to install, but that also means it’s thin and prone to flexing. Steel is an inexpensive alternative, and it doesn’t flex as much – though it’s much heavier and that can make it more difficult to install. Both FRP and steel tubs are fairly hard-wearing, but they can suffer damage over time as they’re prone to scratches and chips.

Acrylic gives you the best of both worlds – it’s light and easy to fit like an FRP bathtub, but with the improved durability of high-end materials. If you want the best of the best, cast iron baths are the most durable of all. Resistant to dents, scrapes and scratches, cast iron was traditionally used for lavish Victorian roll-top baths. It’s also great at retaining heat. But, because it’s so heavy, baths made from this weighty metal can also be tricky to install.

If you’re happy with your current bath but it just needs a little TLC, a skilled bathroom fitter may be able to fix it, depending on the material it’s made from. Repairing an old bath isn’t always possible, but if it can be done it’ll usually be cheaper than buying and installing a new one.


How much does it cost to install a shower?


The average cost of installing an electric shower like for like swap is £300.

The type of shower you choose will probably depend on the plumbing setup in your home. If you’re simply looking for a shower to be installed in an enclosure, there’s a range of shower valves and heads to choose from, so you’re bound to find something to fit your requirements. You might want a simple, minimal showerhead with a neat single mixer valve, or a three-way mixer with a head, hose and body jets. It’s a good idea to look for a thermostatic valve, whatever setup you opt for. These valves have built-in thermostats that automatically keep your water temperature constant, even if a tap’s being used somewhere else in the house – so you can say goodbye to those sudden cold-water shower shocks.

Electric showers are an affordable option. They’re economic, easy to install, and give you hot water on demand. While you won’t be able to enjoy the most powerful water flow (due to the way electric showers work) some top-end, pricier models can deliver a fairly hefty output.

Bath/shower mixers combine a shower hose and head with a bath mixer tap. They’re among the easiest showers to fit, as they’re fed from your mains water and hot water tank, and simply sit above your bath. While they’re dependent on the water pressure of your heating system to achieve a decent flow, pumps can be installed to help here.

Power showers are among the highest-price options, featuring an integral pump to boost the flow rate. These models offer great water pressure, and a luxurious massaging effect, but they’ll only work with certain boilers. Specifically, you can’t partner a power shower with a combi boiler. That’s because combi models heat water as it passes through the boiler. If that flow is sped up with a pump, your boiler won’t have time to heat the water.

You’ll typically pay around £300 to install a like-for-like electric shower, £500 for a new electric shower (including the electric supply), £165 for a like-for-like ‘bar mixer’ shower and £250 for a new ‘bar mixer’ shower.

How much does it cost to install a shower enclosure?


The average cost of installing a shower enclosure is £410.

Your main consideration when it comes to shower enclosures will be the type of door. You could go frameless, hinged, sliding, bi-fold, curved, pivot, or even no door at all. The style you choose will depend on your bathroom. Just keep in mind that the more modern, frameless units are likely to be pricier, while conventional hinged or pivot doors are often thriftier options.

The price of shower enclosures will also be affected by the thickness of the glass. Prices tend to rise as glass gets thicker, so you’re paying more for a solid and robust feel. The typical thickness of a shower door is 6 mm or 8 mm, but 4 mm and 10 mm thicknesses are available from most manufacturers too. Often the 6 mm and 8 mm options are preferable, as the glass is solid enough so as not to feel flimsy, but not so heavy that it becomes expensive to install.


How much does it cost to install a bathroom basin?


The average cost of installing a bathroom basin is £100.

Pedestal basins are popular, easy to fit and relatively cheap. They’re not the most effective option if you’re seeking to maximise space though, because the pedestal stands on the floor. Semi-pedestals or wall-hung basins are more elegant and compact options. These modern units don’t take up as much floor space, which can be particularly handy in snug en-suite bathrooms. You’ll tend to pay slightly more for these units though – both for the product and the installation.

The majority of bathroom sinks are made from either ceramic or porcelain. Ceramic is an affordable but reasonably hard-wearing option, while porcelain is more expensive but it comes with the added benefit of being a bit tougher. Marble is the top-end premium option, and is the most resilient. It can often be repaired, should you scratch or chip the basin, so it’s probably no surprise that you’ll have to part with more cash if you’ve got your eye on a marble basin.


How much does it cost to install a basin tap?


The average cost of a basin tap installation is £90.

Many homeowners choose basin-mounted mixers, as the single tap controls both hot and cold flow. They’re easy to install and look smart too. But taps can also be wall mounted, and this is a neat design feature that elevates the look of your bathroom. As the plumbing needs to be hidden within the wall, this can make installation a bit trickier though, so expect slightly higher costs.


How much does it cost to install a toilet?


The average cost of installing a toilet is £200.

The price of a toilet starts at around £50. For a basic, affordable unit you can opt for a floor-mounted, low-level WC. But, if you’re short on space, you might want to go for a close-coupled toilet or one with a concealed cistern.

For a neat minimalist look, the latter of those options can be installed in a wall-hung arrangement – suspended off the floor. This will be more expensive to fit, as the concealed cistern and pipework will need to be built into the wall. But it’ll look impressive and create the impression of more room.


How much does tiling cost?


The average cost of tiling a medium-sized bathroom is £1,100.

Tile styles, sizes, finishes and quality can vary wildly. And that means the cost of tiling can fluctuate too. The main factors that steer the overall cost of the job are the surface area to be tiled and the price of each tile.

The first of those considerations is simple – the larger the area you want to tile, the greater the cost.

When it comes to the price of the tile, that depends on the material it’s made from. Ceramic tiles are cheaper, and they’re also easier to cut and install. That makes them a popular choice, and most ceramic tiles (certainly those that are thick enough) will be relatively long lasting too. Porcelain tiles are tougher – and that means they’re usually more expensive per square metre than their ceramic counterparts. They’re particularly resilient, but that quality makes them harder to fit.

It’s a good idea to talk to your tiler to understand what you can achieve with your budget. They might suggest only tiling halfway up the wall in some areas of your bathroom – either to cut the overall cost of the project or free up your budget so you can put it towards more impressive-looking tiles.
