Replacing a bathroom window can be a great way to improve the look and feel of your home, as well as increase energy efficiency. But how much does it cost?

The cost of a bathroom window replacement will vary depending on a number of factors, including:

  • The size and type of window
  • The material of the frame and glass
  • The installation
  • Whether you need any additional work, such as new lintels, plastering or decorating

For a bathroom window replacement, you could be looking at a cost of anywhere between £200 upwards of £1,500, depending on your choices.

The size and type of window

The size of the window is one of the biggest factors that will affect the cost. A small window will obviously be cheaper than a large one. The type of window will also make a difference. Tilt and turn windows, for example, are often more expensive than casement windows.

The material of the frame and glass

The most common materials for bathroom window frames are uPVC, aluminium, and timber. uPVC is the cheapest option, while aluminium is more expensive. Timber is the most expensive option, but is more suitable in some types of properties, such as those in conservation areas.

The type of glass you choose will also affect the cost. Double glazing is the most common option, as it is more energy efficient than single glazing. Triple glazing is even more energy efficient, but it is also more expensive.

For the UK, double glazing is often the recommended option as it provides a good trade-off between cost and energy efficiency. But if you have the money, then triple glazing can provide longer-term value.

The installation

The cost of installation will vary depending on the complexity of the job. If your window is in a difficult-to-reach location, for example, it will cost more to install. Additionally, where you live will also have an impact, as installation costs vary across the country.

If additional items such as scaffolding and waste removal are required, this may incur additional costs.

Whether you need any additional work

If you need any additional work, such as plastering or decorating, this will also add to the cost. Typically, this is not covered as part of a standard window installation and you’re best placed to find a contractor to carry out any further work required other than the window installation.

How much does it cost to replace a bathroom window?
