A rocking toilet can be the source of water leaks and odor problems in your
bathroom. A rocking toilet could simply be caused by the toilet mounting bolts
not adequately tighten. It could also be due to an uneven bathroom floor
underneath the toilet or a damaged toilet flange. No matter what the cause,
rocking toilet repair is essential. If left unchecked the toilet bowl could
eventually crack, water leaks could occur, and a subtle odor may become
The simplest and easiest rocking toilet repair that you can attempt is to
gently tighten up the toilet mounting bolts.
However, be very careful to not
over-tighten them as you could cause the toilet bowl to crack.
If you are convinced the toilet mounting bolts are snug with the toilet bowl
surface, try placing small wooden shims underneath the edge of the rocking
toilet. Use a utility knife to remove any excess shim material, and use a hammer
and common screwdriver to gently tap the shim so that it sits slightly recessed
underneath the bottom of the toilet bowl. Then apply a bead of bathroom silicone
caulk around the base of the toilet bowl.
If the toilet rocking is significant, e.g. more than 1/8th inch of play, then I
would highly suggest removing the toilet and inspecting the area underneath the
toilet and around the toilet flange. When removing a toilet, make sure to first
turn off water to the toilet and fully drain the toilet tank and bowl. Then
remove the toilet mounting bolts, and lift the entire toilet assembly carefully
up and out of the way. A second pair of hands can be very useful during this
Set the toilet aside and inspect
the area underneath the toilet area to make sure it is level. Also make sure
the toilet flange is not damaged in any way.
|Assuming the floor is level and the toilet flange is fine, install a new toilet
wax ring to the base of the toilet bowl and re-install the toilet. Make sure
when re-installing the toilet that you slightly twist the toilet back and forth
onto the toilet flange and press it firmly into place. Then fasten the toilet
down with the toilet mounting bolts. If there is still a bit of rocking toilet
“syndrome” going on, then use the shim and caulk rocking toilet repair method to
resolve the problem.
