The invention of indoor plumbing catapulted us to a place of convenience, privacy and indulgence. Now, bathrooms are an essential part of modern living, and the more people staying in your home, the higher the demand for bathrooms is.
What’s more, new buyers may be put off your home due to a lack of bathrooms. With these reasons in mind, exactly how much value does another bathroom add to your home?
Today we’ll aim to answer that question plus take a deeper look into whether it’s worth adding a second bathroom to your home.
Do bathrooms add value to a house?
You may be considering adding a second bathroom for convenience, especially if your family is growing. And, in terms of the value of your home, you may be wondering do bathrooms add value to your house?
Well, not only can a new bathroom increase your home’s value financially, but when viewing properties, many people will be put off by a lack of bathrooms. As such, adding a new bathroom can greatly raise the selling price of your home plus make selling much easier.

How important is a second bathroom?
While many people are happy to live with just one bathroom, adding an additional bathroom can bring a range of benefits. If you’re curious about how important a second bathroom is, consider the following:
- Socialising and entertaining: If you plan to have guests over for parties or overnight stays, having an extra bathroom can give your visitors their own space.
- Convenience: Deciding to install a downstairs bathroom is a great choice. This will mean you don’t need to traipse upstairs every time you need to use the bathroom. This is particularly important if you have mobility issues that make it hard for you to climb stairs. You can even add an ensuite for added convenience.
- Expanding families: The more children you have or are planning to have, the higher the need for an extra bathroom will be.
- Relaxation: If you live with family members it can be difficult to spend time in the bathroom relaxing alone if young people constantly need to use the toilet urgently.
- Added value: As we previously discussed, adding an extra bathroom could add thousands of pounds to the value of your home.
- Summary: So is it worth adding a second bathroom? If you want a convenient, private place to relax that raises the value of your home, yes, it’s absolutely worth the investment.
