How to install a toilet

1. Start by fitting the cistern parts using the instructions provided.

When you unpack your cistern you will find all the connections, screws, bolts and bits required for installation, including a seal. Most cisterns have a way of being fixed to the wall so check your cistern and grab a tape measure.

here is a small list of Cistern types you may need

• Close Coupled Toilet Cistern – This cistern is connected very close to the pan. That’s where this toilet gets its name. 
• Low Level Toilet Cistern – A traditional style cistern for traditional toilets; low level cisterns are fixed just above the pan and usually have a gap between them and the pan.
• High Level Toilet Cistern – Another traditionally styled cistern for a traditional toilet; high level cisterns are fixed high up on the wall above the pan and require a step or step ladder to gain access.

2. Connect the cistern to the pan.

One of the easiest and most common cisterns to install is a close coupled cistern. This cistern sits on top of your close coupled toilet pan and is typically secured by two bolts with square ends. Slot them into fixings either side of the seal on the underside of your cistern or where your instructions suggest. The top of your toilet pan will have a hole (usually in the centre) where the water will pass from the cistern into the pan when you flush it. Place your seal on top of this hole. Now take your cistern and carefully position it over the pan and ensure all the screws line up. Now take your nuts/wingnuts and tighten the screws which hold the cistern to the pan; this can be a fiddly process so try to have some patience! The cistern will need fixing to the wall; although this is purely for keeping the cistern in place and won’t require to much work.

3. Mark holes.

Check that there are no pipes or cables beneath the fixing points. Put the toilet in place, and slide the pan outlet into the flexible connector that’s attached to the soil pipe (a little silicone grease will ease it on). Then drill some pilot holes into the floor at the fixing points. If it’s a solid floor, you’ll need to make the holes with a hammer-action drill and plug them.

5. Fix toilet to wall and floor

Follow your product’s instructions at all times as these cisterns do differ from one to another. Measure up your cistern against the walls and mark out your drill holes. Ensure the piping lines up with your toilet and use a spirit level to ensure the cistern isn’t wonky. Your water supply pipe will typically be above the cistern itself so if you’re installing your toilet from scratch then we recommend getting a professional to help here. .

Push plastic protective inserts through the holes in the base of the pan, and insert the retaining screws through and into the floor. If the cistern has fixing holes in the back, attach it to the wall by drilling and plugging. Remember to add rubber washers before you tighten the nuts.

6. Connect the pan to the waste pipe.

If it is not a straight waste pipe then connect the waste pipe over the waste hole in the toilet and secure it with the fittings supplied.

7. Attach the water inlet pipe

Taking care not to over tighten. Connect the water pipe to the cistern and using a wrench, tighten up until it’s nice and secure. If your cistern is connected to the toilet; a close coupled toilet for example, then you’ll need to connect it to the toilet using the nuts and washers provided. Adding a small amount of sealant where the bolt sits against the cistern will add an extra level of waterproofing.

8. Turn on the water and check for leaks

9. Fit the hinge assembly to the seat

Following the manufacturer’s instructions. Connect the seat to the pan by securing through the holes at the back, using the screws supplied. Then adjust it to sit in the correct position.
