Most bathroom renovations include changing out the old toilet for a new one. This is mainly because most homeowners want to keep the bathroom fixtures uniform in colour and style. For example, if the new bath tub chosen is a rose coloured, antique-style the sink and the toilet should follow in this design to maintain the continuity.

In most households replacing a two-piece toilet can be accomplished by an amateur in a few hours using a few rudimentary tools. Many varieties of toilets are available in kits with all the materials needed to complete the operation in one box.

Before Assembly


The following instructions cover the installation of a two piece toilet. Familiarize yourself with every step of the process before undertaking the installation of a toilet. And do not hesitate to call your renovation centre if you have questions.

Check to see if low-flush toilets are required in your area.

Wear kitchen gloves when sponging out the old toilet tank.

The tank and bowl are heavy so wear a back support and lift with the legs. If possible, get a helping hand.



If there is not a shut-off valve below the toilet, a competent plumber should be brought in to install one.

Call a professional if the toilet has been slowly leaking over a long period of time as the flooring may be rotted.



Before heading to the store, measure the distance from the wall (not the baseboards) to the bolts holding the bowl to the floor. This is referred to as the "footprint". The standard footprint is 12". However, it can vary depending on the age and style of the toilet. Make sure your new toilet will fit.

Remove all the packaging and inspect the toilet carefully for cracks or blemishes in the glazing that may have occurred during shipping.
