To steady a rocking toilet, cut plastic shims to fit and slip them underneath (you may have to remove caulk before adding shims). Then caulk around the toilet and snug down the nuts on the bolts. But don't crank them down super-tight; that can crack the toilet.

Why does my toilet wobble when I sit on it?

Toilets wobble when they aren't held securely to the floor, and if you let the wobble persist, they can leak and give you more serious problems. More often than not, the wobble is caused by loose toilet bolts, but the flange may also be responsible. It may be corroded, broken or set too high.

Why is my toilet bowl rocking?

The flange bolts are loose

One of the most common things that causes a toilet to rock back and forth are loose flange bolts. These are the bolts that hold the toilet down at an even level with the floor in your bathroom.

Should I caulk around toilet?

Caulk Keeps the Toilet Secure

Think again! Caulk keeps your toilet secure the floor, and avoids any chance of injury or toilet malfunctioning. It's actually required by the International Plumbing Code to caulk a toilet to the floor, and now knowing the reasoning behind it, why would you not want to?

Why is my toilet rocking back and forth?

Toilets usually rock because they are not resting flush against the floor. Underneath the toilet base is a round toilet flange that connects the toilet to the drain pipe. If the flange is a little higher than the surrounding flooring, the toilet becomes raised slightly in the center, allowing it to rock to either side.

How tight should the bolts on a toilet be?

Bolts Don't Have to Be Extremely Tight

In some cases, hand-tightening and a quarter-turn is all you need. It's important to keep in mind that the toilet tank is not intended to take weight and strain. The tank-to-bowl bolts are merely there to ensure the rubber seal between the tank and bowl is snug and leakproof.

Does a toilet need to be bolted down?

Closet (toilet) flanges must be 1/4" above a finished floor. This is so the wax ring seals properly to the flange and the hub on the toilet. If a proper seal is not achieved it will result in leaking. If the flange is lower than or flush with the floor they make foam rings that cover the distance for a proper seal.

Can a wobbly toilet cause a leak?

A wiggling toilet

A loose toilet can cause a leak at the sewer line, and worse, flood the bathroom floor. It can lead to rotted wood and mildew and mold problems. If neglected, the leak can destroy the floor, leading to costly repair and replacement. If you notice that your toilet is loose, call a plumber for help.

Do new toilets still use wax rings?

Wax Ring. The most basic of all toilet seals is the wax ring. This type of seal has been around for quite a while and is still a great choice under the right circumstances.

How do I know what size wax ring I need for my toilet?

To determine the correct width for your wax ring, simply turn your toilet bowl on its side, and measure the opening on the bottom of your toilet, called the “elbow neck.” Whatever width this measurement is, use that width wax ring. E.g. if the elbow neck measures 3 inches, use a 3-inch wax ring.

How do I know if my wax ring is sealed?

To test that a bad seal is the problem, grab a couple of towels and wipe up the water. Go on with your day, checking periodically to see if the water has returned. If the floor is still dry, chances are that the water wasn't coming from the toilet's base.

Why is my toilet loose from the floor?

Probably the easiest fix, your loose toilet may simply be due to your loose toilet mounting bolts needing to be tightened. Simply remove the small plastic bolt caps at the base of your toilet (they will be on each side, and can be pried off with a small screwdriver).

Is the toilet flange supposed to be flush with the floor?

For those that don't already know, the proper toilet flange height is when it's flush with the top of the finished floor. The optimum height is about ¼ inch. It's easier to get your flange flush with the floor if you lay your flooring before you install the flange.

How long do toilet wax rings last?

The wax ring is exactly what it sounds like: a ring made of sticky wax that helps form a watertight seal between the bottom of the toilet and the sewer pipe. It requires no maintenance and can last 30 or more years, often as long as the toilet itself. But sometimes wax rings can dry out, crumble, and fail prematurely.
