With summer in full swing, cold showers are better than ever. There's nothing more refreshing after a hot and sweaty day than taking a quick, cool dip to cool off and clean up. If your shower has no cold water, you may be in a bit of a bind here. Luckily, we have all of the fixes you could need.
The most common cause of a shower with no cold water is a defective pressure-balancing valve in your shower's cartridge.
There's good news and bad news with this. Good news - it's fixable. The bad news is that it's a rather involved process. Keep reading to learn how to replace a pressure-balancing valve and when to call a pro.

Okay, first off, let's make something clear - you're going to need to be at least slightly mechanically inclined to do this, and you will need a special tool. If the idea of disassembling your shower is scary or you don't want to buy a tool, hire a professional. It'll usually cost you around £100 to do for parts and labour, and will make things a bit easier on you.
Now, if you're dead-set on repairing this yourself (look at you, Mr./Mrs. Handyperson), then keep reading.
To perform this repair, you'll need several things:

If this didn't fix your issue, there are a couple of other things to check first.
If you've replaced your cartridge to no avail, take a walk and do the following.
This is usually a good indicator of what's wrong in the home. If your other faucets don't provide cold water, you likely have a shutoff valve in your home that's activated. It doesn't really matter how this happened; give it a look. Switching it back may solve your problem.
As mentioned in our article about cleaning an electric shower , cleanliness is important to your shower's functions. Buildups of limescale or other minerals can cause major issues with your water temperatures.
Poor water pressure could affect your shower's temperatures. If your pipes are unable to bring cold or hot water quickly enough to you, it'll come out lukewarm. Check out our article here about other potential causes of varied water temperature .
If this is a common problem for you, it may be worth it to make the leap to the 21st century. Electric showers are great in just about any home for one major reason - they heat the water separately from your boiler. This means you don't have to worry about running out of hot or cold water, regardless of exterior circumstances. Check out our guide to the best electric showers available today for more information.
While nobody likes to hear this, pros exist for a reason - not everyone can confidently make these types of repairs. If your shower still has no cold water, this may be the best bet. The same goes for lack of hot water.
We recommend calling a professional in this case because it's important not to cause further damage to your home's plumbing. Misuse of cleaners or tools could actively damage your plumbing or even cause leaks. This will result in more expensive repairs in the future - so if you're not comfortable, make the call.
As with all things in your home, showers are surprisingly complicated. If your shower has no cold water, there are a few things that could be causing this. While it's most likely that your cartridge needs to be replaced, it could also be a fault in your water pressure, a shutoff valve, or mineral buildups. By following the steps laid out above, you'll be back to chilly showers in the summer and hot ones in the winter in no time.
And don't feel ashamed of calling professionals for help. I know it's a bit of a touchy subject for many people, but help isn't bad . If you're not comfortable with making repairs and buying specialized tools, get your local plumber to come and take a look. It's not worth damageing your home's plumbing to save a few bucks. And maybe consider upgrading to an electric shower - we're in the 21st century, so your home should be too!
