How to unblock a bath or shower

No one wants to take a shower standing in an inch of water. And you definitely don't want your cubicle overflowing onto the bathroom floor, either. Luckily, we know just how to deal with a blocked bath or shower, and these 7 easy steps will take you through it.

1. Bring the right tools

You might not know exactly what's causing your blocked bath or shower. So to be safe, make sure you don't have to come into contact with any of the water. Before you get started, you'll need:

  • protective glasses and gloves
  • some baking soda
  • some white vinegar
  • some bleach

2. Start with the baking soda

Put on your gloves and glasses, and then carefully pour a small amount of baking soda down the blocked plughole.

3. Follow it up with the vinegar

Pour a cup of the white vinegar down the plug hole, on top of the baking soda. You should be able to see or hear the mixture start to bubble away, hopefully breaking down some of the debris that's causing your blocked bath or shower.

4. Rinse through with warm water

If the baking soda and vinegar seem to have cleared the blockage, use your shower head or bath taps to gently flush the mixture through the drain with some warm water.

5. Add bleach with care

Alternatively, you can pour a small amount of bleach down the plughole to try and clear the blockage, being careful to follow the instructions on the bottle. Don't try using any heavy chemicals, such as caustic soda – the residue from these kinds of products can hang around in your drain for hours.

6. Flush the bleach through

When it looks like the bleach has cleared the blockage, use the shower head or bath taps to rinse it down the drain with some warm water.

7. Don't use a plunger

If the bleach or the baking soda and vinegar haven't done the trick, try to resist bringing out the plunger. While it's useful in many other plumbing situations, it's not a good idea to use a plunger on a blocked bath when you can't see all of the waste pipe. If you've followed these steps, you should now know how to unblock a bath or shower. But if you're still stuck, or you're not comfortable trying these methods yourself, get in touch with one of our engineers – they're always happy to come and take a look.
