If water is leaking from beneath the toilet, you might be able to stop it by simply tightening the closet bolts that secure the toilet to the floor. Use a putty knife or slotted screwdriver to pry off the caps that are covering the bolts. Then use a wrench to alternately tighten each bolt, a little at a time.
When a toilet leaks at the base, with water pooling on your bathroom floor, it's typically due to the failure of the wax gasket that seals the toilet to the floor. This seal should make a watertight connection between the toilet and floor. A leak often means that the wax seal may need to be replaced.
In theory, the wax ring “should” last the lifetime of the toilet, or certainly 20 to 30 years. We come across situations all the time, however, where wax rings are in need of replacing well short of this scenario.
Wax-free toilet seals are made out of a heavy duty rubber, so they're flexible enough to shimmy into the flange without smearing a wax ring. Wax-free seals can also be reused. As long as they're still attached to the bowl in good condition, you can reinstall the toilet without replacing the seal.
As a result, having a local plumber replace your toilet's wax ring can be anywhere from $75-250 depending on the cost of the trip charge and whether anything else is discovered in the process that needs fixing.
The most common place for a toilet to leak is at the wax seal. Replacing a wax seal may be as cheap as $50. Other common leak points are the tank and bowl which may cost $300 or more to repair.
🚽 Caulking Prevents Water Contamination
It could be water splashing out of a bathtub, mop water, water from a shower and even misguided potty training from your young boys who seem to miss the toilet bowl every single time! Without caulk around the toilet base, water can get under there and sit for a long time.
Water pooling around the base of the toilet can indicate that the wax ring is leaking, or there could be a crack in the toilet tank. A toilet that runs frequently usually means there's a leak between the tank and the bowl.
Flex Glue can be used for an assortment of bathroom repairs. Customers often use the waterproof glue to fix toilet tanks, shower tiles, sink pipes, and other bathroom needs. Flex Glue is also mold and mildew resistant, making it perfect for bathroom repairs.
Flexseal clear aerosol sealant is fantastic. I used it on my toilet ceramic that had a small leak. I cleaned the surface first and then applied a couple of layers of flexseal and the leak stopped.
Silicone caulk is the go-to option for sealing around plumbing fixtures, such as sinks, toilets, and faucets, and for any caulk joints on the tile in wet areas.
Again, leaky water is a telltale and common sign of a bad wax ring. If you do not regularly see moisture or puddling water under your toilet, you may be fine. Leaks can, however, happen where you do not see them, under the finished floor and into the subfloor.
A damaged wax ring doesn't seal the connection between the toilet and sewer line. This causes water to leak out and pool around your toilet. If you catch this issue quickly, then it may not damage your subfloor and require additional repairs. Some leaks are constant, while others only occur when you flush the toilet.
Once water begins seeping through a compromised wax ring, it won't stop. It doesn't take standing water long to rot a subfloor. The resulting sponginess makes the toilet rock even more and worsens the leak.
The choice between wax toilet seals and wax-free toilet seals ultimately comes down to your personal preference. Many professionals stick with wax because they know it's reliable, and they're paid to deal with the mess. If you're more comfortable with the tried-and-true approach, go with a wax seal.
Place the wax ring on the closet flange, not on the toilet. Pick up the toilet and set it evenly over the closet flange, making sure the bolts come through the bolt holes in the toilet base. Fine-tune the toilet position, so it's right where you want it, then push it straight down so it smashes the wax evenly.
Caulk prevents smell
If you don't caulk a toilet to the floor, you could find yourself smelling leftover residue from smelly mop water, tub water, or even worse, the remnants of your son's potty training.
You should always consider replacing the toilet supply when replacing the wax seal. If toilet is caulked to the finished floor of the bathroom, score the caulking all the way around the toilet base with a razor knife.
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.
Replacing the wax ring is as easy as sliding the new piece onto the bolts in the floor, then sliding the toilet down to make a tight seal.
A typical price for Toilet Wax Rings & Floor Seals is $10 but can range from approximately $1.63 to $62.
