How to Install Toilet Seats

Updated June 18, 2018

If you own a home, eventually you'll have the task of replacing a toilet seat. Whether it's because the old one is broken, or just because you want a new look, a new toilet seat is bound to enter your life at one time or the other. This is one of those home repairs you don't have to call the plumber in to do it for you. You can do it yourself and save some money on the repair. You'll just need a few basic tools and, in no time, your new toilet seat will be installed.

Measure your existing toilet seat. You''ll need these dimensions when you go to purchase a new one. Since there are so many types of toilet seats on the market today, it's better to have your measurements with you so you won't pick up the wrong one.

Unscrew the mounting hardware that's attached to the old toilet seat. If you lift the hinge covers, you'll be able to see where the hardware is attached. Remove the old toilet seat and throw it away.

Clean the area where the new seat is going to be attached. Depending on how dirty it is, you might need to use a soft scrubbing cleaner to remove any old dirt and residue. You will also need to clean up the area on the bottom of the toilet where the old hardware was attached.

Place the new toilet seat in place. Make sure to lift the hinge covers while doing so. Align the mounting holes in the toilet, to the holes in the new toilet seat. Once the seat is properly aligned, insert the bolts to hold the seat in place.

Take one of the two new nuts and thread them onto each bolt, making sure the seat is properly aligned before tightening the nuts. Once this is done, you can tighten the nuts with your wrench and screwdriver, until the seat is firmly in place. Close the hinge cover and your new toilet seat is now installed.
