Does an Extra Bathroom Add Value?

You may be looking into the value of your house because you're intrigued, or, you want to move onto a new chapter in your life - will an extra room, specifically a bathroom, add more value to your house? Read on to find out.

Finding out the value of your house is good to know regardless if you’re selling or not. It's always wise to keep an eye on the housing market because you never know if it's going to drop or spike, which will impact the price of your house. Having more than one bathroom is definitely going to increase interest from buyers, especially if they have a family or need to get ready at the same time as their partner in the morning. No one wants to be banging on the bathroom door asking their significant other or family member when they're going to be out. If you're given the choice between one bathroom or two and can afford it, you're obviously going to choose two - it's more convenient and considered a luxury.

The renovation of an existing bathroom can cost between £3,000-£5,000 on average. This can depend on where in the country you live, the price of the products you choose and the plumber/electrician fee. Direct Line Home Insurance reports that by creating an extra bathroom, you can add up to £12,000 to a 3 bedroom property. However, there are different ways you can implement an additional bathroom which you need to take into consideration. One way is an extension, another is replacing a smaller room, or, you can build a bathroom within a room.


Adding an extra room to the house via extension doesn't come without a cost though - will the return make it worthwhile? There's no point in spending more money than the value it will actually add. You will also need planning permission to be approved to carry out an extension on your house, not to mention the loss of space if you extend into the garden. Nowadays, people are converting their loft so they can add an extra bedroom as well as a bathroom. Obviously, this type of extension can cost over £25,000 in total, but the additional bedroom and bathroom can be a game-changer. According to Ideal Home, a loft conversion can add between 10-20% to the value of your home, so if you can spare the funds for this renovation, it is definitely worth looking in to.

Replace a Smaller Room

You can replace a room (for example a small bedroom), but this could potentially decrease the value. As much as having an additional bathroom can be a key selling point, reducing the number of bedrooms can have a very negative impact. Buyers with family (or looking to have one in future) who need additional rooms will usually be put off by this choice. If you have an extra room that isn't necessarily being used, i.e. a study, then you could consider transforming it into a bathroom. You might need to think about where the pipework is though so you can place the products in appropriate areas of the room.


Build Within a Room

If the master bedroom is a fairly big room with excess space that you don't need to fill up, you can put in partition walls and create an en suite bathroom within the room. The downside is your bedroom size is reduced, but you’d be gaining a bathroom simultaneously which adds another function to your house. Adding an en suite to a master bedroom is a huge selling point and having a big bedroom isn't really necessary as it's mainly only used for sleeping - so why not make the most of the unused space?

I think we can all agree that for every bedroom we'd love them to have their own bathroom (think of all that cleaning though!). If everyone in the house had their own bathroom, they could design it however they want and spend as long as they want in there without being rushed out. However, for most houses in the UK, this won't be the case as space needs to be optimised for families and essential rooms.


If you’re looking to sell your house, make sure that your bathroom doesn’t have any leaks or broken parts. When I bought my house, I had the en suite ripped out and replaced as it was very worn and outdated. We found out that the toilet had been leaking underneath which they had tried to cover up by painting the living room ceiling in thick paint! If you notice something wrong, then try to get it fixed before you put your house on the market. If you’re unable to, then it is best to let potential buyers know what they are dealing with. I know some people wouldn’t want to say anything just to make the sale, but the buyer will appreciate the information and can get it fixed asap.

In conclusion, an extra bathroom, in general, will add value to your house, but it all depends on how you go about including it into your floorplan. Don’t spend more money than what the additional bathroom will add to help the house sell at a higher price. Talk to different estate agents, builders and evaluators to get an idea of which option is best for you if you are unsure.

If you’re unable to add an additional bathroom, whether it's because of cost or space, then simply updating your original bathroom can still contribute to raising the value of your house.
