The thought of adding a new bathroom to your house might seem like a big expense, but is it actually as costly as you think? Costs will vary depending on what type of space you want, whether it is a complete renovation, extension or you just want to install a toilet in a small space. The average cost around to add a bathroom can depend on variants such as the existing space in your home, the going business rates and materials needed. Therefore, before looking to install a bathroom, make sure you have done adequate research around the cost of bathroom fitters and the bathroom extension or bathroom renovation.

The Typical Cost of Adding a New Bathroom

The price of your new suite will alter depending on varying factors, however, the typical price to add bathroom suite averages between £3,000 to £5,000. The total price could be less, if you decided not to replace any of the flooring for example, or it could cost more if you decided to include an installation that is more expensive, such as a wet-room. It is a wise idea to calculate your budget and get a quote for your new addition.

What Affects Installation Costs?


If you already have a bathroom in your house that you just want renovating, that will be significantly less money than if you are installing a new suite altogether. This is due to existing plumbing work meaning that you will only need to pay for installing the new suite itself.

If you want to add your bathroom suite into a space with no existing adequate plumbing, this could cost upwards of £1,000. This factor would affect the installation price quite drastically and is useful to bare in mind when choosing where to place your new suite.

Waste Disposal

This is often something that homeowners forget to factor into their budget when calculating the price for their new bathroom. If you want all new pieces for your suite replacing old ones, then you might need a skip-which can cost anywhere between £100-400, depending on size and where you live.

Alternatively, the council may take your waste away for a small fee (again, depending on where you live), or you might be able to cut the cost completely and dispose of it yourself at a local tip.

Quality and Finish

The quality of the bathroom will affect the bathroom installation costs. The better quality, the more expensive it will be. It is also worth considering how long you are looking for your bathroom to last. If you have just moved into a new home and are looking for a bathroom to last you 20 plus years, it might be worth investing in a more expensive bathroom to achieve that longevity of the suite.

The finish of your bathroom will also affect the price; for example, vinyl flooring is cheaper than limestone flooring and a whirlpool bath is more expensive than a regular one. Similarly, heated flooring can range between around £120-170 per square metre, driving the price of your bathroom up.

Considerations for Adding a New Bathroom


It is useful to consider how small or large you want your installation to be. Do you want it to be a cosy en-suite? Or do you want a large bathroom, complete with a wet-room and jacuzzi? Obviously, the bigger the space, the more expensive it will be. Working out the size of your desired bathroom per square meter will help calculate an accurate cost.
