How to Replace a Toilet Seat
Pry open the bolt caps.
Use a screwdriver to pop open the bolt caps.
Hold the nut on the underside of the seat bolt.
Use the adjustable wrench to hold the nut located on the underside of the seat bolt.
Remove the seat bolts and lift off the seat.
Turn the seat bolts with the screwdriver. After you remove the nuts, lift off the seat.
Push the anchor bolts of the new seat through the holes and hand tighten the nuts.
Align the bolt holes of the new seat with the holes of the toilet base. Push the anchor bolts through the holes, and then screw on the nuts from the underside of the bolts until they’re hand-tight. Center the seat and then tighten the nuts.
Once the seat is centered, use the adjustable wrench to tighten the nuts. Don’t over tighten the nuts — just beyond snug is good enough.
