In this third and final part of our series on replacing a toilet, we'll deal with the installation of the new unit. An essential component of both stylistic and functional DIY bathroom renovations, you're sure to be relieved when this part of the job is complete.
Bolt it down
It's time to set your closet bolts. Hopefully you've selected the solid brass variety, as they resist corrosion. In an area as wet as a bathroom, this is a pretty important point. When you're putting them in place, they need to be parallel to the wall at the rear of the bowl. In other words, one on either side of the toilet.
Make sure you have your wax ring in place. If it's cold and inflexible, letting it heat up a bit will help you get it on easily. Some installers prefer to place the wax ring on the flange and move the toilet on top of it. Whichever you find easier is fine.
At this point you need to unplug the drain hole and manoeuvre the bowl into position. Once on the bolts, press it down firmly and loosely tighten up the nuts on the closet bolts (with washers installed).
Next, it's time to pull out a measure and make sure your loo isn't on a lean. If it is, you may need to shim it. Once you're happy that everything is levelled out nicely, tighten the nuts on the closet bolts and put the bolt caps on.
Are you ready to get to the real plumbing work? Installing the tank! Before the cistern is attached, make sure the rubber gasket is installed at the base of the tank - check the instructions that came with your toilet to see how this applies to your particular model.
The bolts that secure the cistern to the bowl should be inserted from the inside of the tank. Once the cistern is in place, tighten these up, but not too much.
Lastly, you need to connect the supply line and the toilet seat - flexible supply lines are easiest to fit. Your toilet seat will differ from model to model, but essentially these are usually fastened with screws and covered with plastic hinge caps.
Before you get down to business, turn on the supply tap and ensure the flush is working properly. Some minor adjustments might need to be made at this point so make sure you don't get caught with your pants down and follow the manufacturer's instructions carefully.
