How To: Fit A Toilet - Installing Your New Toilet

Hands up who started a lockdown DIY project? Whether you decided to turn your hand to home decorating or fitting your new bathroom, enforced time at home has seen a huge rise in demand for DIY equipment. Of course, if you are unsure about your skills, it is always best to employ a professional tradesperson. If, however, you want to try out your plumbing skills, installing a new toilet is probably the easiest, most risk-free place for you to start.

Last week, we looked at how to remove your old toilet. This week, we get to the fun bit! How to install your new toilet in the existing location. If you need to install a toilet in a new location, contact your local plumber.

You will need:

  • Screwdriver
  • Silicone
  • Wrenches
  • Adjustable pliers
  • Flexi-hose to supply the cistern with cold water. Your existing toilet probably has a flexi-hose, but it is worth buying a new one
  • Sealant
  • Sealant gun
  • Soft cloth
  1. Measure up. The first step is to measure and mark for drill holes; the new loo may not have the same fixings as the old ones. If your toilet has an outlet underneath, instead of at the back, you will need to remove the soil cover and put a new wax ring in.
  2. Connect the toilet. With your toilet in place, you need to use the pan connector to connect the waste to your new toilet; remove the waste cover and ensure that the connector is securely attached.
  3. Install your cistern. Next, you need to install your cistern. There are three main types of cistern: close coupled, low level and high level. Attach your new flexi hose to the cistern; be careful not to over-tighten the pipe. A close coupled cistern is most common and easiest to install; it sits on top of the toilet and is fixed to the wall. Once your cistern is secured, connect the new flexi hose and tighten the connection until it is secure, but not too tight.
  4. Check for leaks. Once your water and waste pipes are connected, you can switch on the water! Check the water supply and waste for leaks before you use the toilet for real.
  5. Seal your base. With your toilet fixed and pipes attached, you can seal the toilet base to the floor using bathroom adhesive; a layer of adhesive on the water pipe could also help to keep it watertight.
  6. Ready, steady flush! Once you’re sealed and you’ve checked for leaks, you’re ready to use your new toilet!

As it doesn’t require multiple attachments, fitting a toilet should really be as straightforward as it sounds.
