Signs You Should Replace Your Toilet 

In most cases, toilets don't simply break down or give out in a single day. Toilet problems usually evolve slowly, but worsen the longer you leave them unattended. Once they get bad enough, your only option is to replace them with a newer one. Here are some of the top ways to tell if you've reached this point.

Cracks Along the Base of the Toilet

One of the most obvious signs that it's time to replace your toilet is if you notice cracks along the base or tank. Cracks can start out tiny, but they tend to grow and worsen quickly. Eventually, you could have a leaky or busted toilet and a massive mess on your hands.

Frequent Clogs

While frequent clogs could be the result of a clogged sewage or drain line, it could also be the fault of the toilet. The only way to know for sure is to contact us and allow one of our licensed plumbers to perform an examination of your plumbing system. There's no sense in replacing a perfectly good toilet if your pipes are causing the problem.

A Leaky Toilet

A leaky toilet is also a cause for alarm and can happen in multiple places. The two main spots to watch out for are at the bottom of your toilet where it meets the floor, and at the back of your toilet where it connects to the tank. Either way, your best bet is typically to replace the toilet rather than try to fix it.

An Unstable Toilet

An unstable toilet that rocks back and forth or side to side is usually a precursor to a leak. Toilets aren't meant to move around once they're set in place, so make sure that you firmly fasten them to the floor.

How to Replace a Toilet

Replacing a toilet is difficult, tedious, and dirty work. However, if you think that replacing a toilet DIY-style will save you money, here's what you need to do.

Step 1: Choose a Replacement Toilet That's the Right Size

The first thing you'll want to do is take measurements of your old toilet so you can purchase a new one that's the same size.

Step 2: Turn Off the Water Supply and Flush the Tank

Once you have your replacement toilet ready, you can start with the replacement process. First, turn off the water supply at the back of the toilet and flush the toilet to get rid of the existing water in the tank. You can use a sponge or shop vac to get rid of any excess water in the tank and bowl.

Step 3: Remove the Water Line and Tank

With the tank and bowl empty of water, disconnect the water supply line, and remove the bolts connecting the tank to the toilet bowl. Once the bolts are removed, you can lift the toilet tank off the bowl and set it safely aside.

Step 4: Remove the Toilet Base and Wax Ring

Next, remove the toilet itself, as well as the wax ring underneath it. You'll need a wrench to loosen the bolts holding the toilet in place, and you may need a putty knife to remove any excess wax left behind. Once everything is loosened, set the old materials aside and make room for the replacement toilet.

Step 5: Install New Closet Bolts and Wax Ring

Before setting the toilet in place, make sure to check the toilet flange. If it's still intact, you don't need to replace it. If it appears damaged, however, make sure to replace the flange with a new one. At any rate, you'll want to install new closet bolts to hold the toilet in place if your old ones are damaged. To do that, simply remove the old ones near the flange, and set the new ones in their place.

Next, you can either attach the wax ring to the bottom of the toilet or set it in place in the middle of the flange. Either way, make sure to follow the instructions attached to your wax ring.

Step 6: Install the New Toilet

If your closet bolts and wax ring are ready, go ahead and set the new toilet in place. Make sure to set it down so that you don't have to wiggle it around as that could damage the wax ring and cause a future leak. You also want to ensure that the toilet is sitting straight so that it isn't crooked with either wall it's close to.


After the toilet is set in place, tighten the nuts on top of the closet bolts to make sure that the toilet can't move. It may take several turns on either side to fasten the toilet firmly in place, as it takes a few minutes for the wax ring to compress. During this time, you can also attach the toilet tank to the back of the toilet, install the toilet seat, and reconnect the waterline.


With everything in place and ready to go, turn the water back on. Allow the tank to refill, then perform several practice flushes to ensure there aren't any leaks in the waterline, between the tank and toilet, or between the toilet and floor.

Toilet Replacement Cost

If you replace your own toilet, you're likely looking at between $100 and $200 depending on the materials you purchase and the type of toilet you choose. Make sure to remember a wax ring, a possible wax ring extension, closet bolts, and water line accessories if necessary. Having your toilet professionally replaced usually costs around $250 and $500 when you factor labor into the equation.

Who to Call for Toilet Replacement Services

While it's possible to save a little money by replacing your own toilet, having 1-800-Plumber + Air do it for you will save you time and give you peace of mind. Toilet replacements are nasty and finicky jobs, and we have the skills, equipment, and expertise necessary to make the process go as smoothly as possible.

The Sink

After a visit to the throne, where's the next place everyone heads? The sink, of course. This fine fellow has a similar number of moving parts.

The Faucet

First up, we have the faucet lever which turns things on and off. The lever connects to a dome which houses a cartridge that connects to a spout O ring. The spout O ring is about as thick as a sheet of cardstock but is integral to a secure connection.

The spout O ring connects to the faucet spout which has another O ring. At the end of the spout, there's a little O ring that connects to an aerator which delivers a mixture of water and air. Essentially, this helps prevent too much of a splash from developing.

Going back to the other side of the spout, back at the base of the sink, there's one more O ring that connects to the escutcheon, which is a fancy word for "flat piece of metal."

The Basin

The basin is pretty straightforward. It's part of the reason why you can purchase practically any shape, style, or material for your basin. It can be glass, porcelain, marble, bronze, you name it.

Here, you have the basin and a drain. Nice and easy. But, on top of the drain, you can install a sink hole cover or a sink strainer.

A sink hole cover allows you to seal the drain and draw some water into the basin. This is, of course, great for face washing, shaving, and other daily routines.

But you can also install a sink strainer. If there are any ladies in the house, then, every time they brush their hair, there's a strong likelihood they'll brush a few strands down the drain. Over time, this creates one of those gag-worthy clogs that will need to be snaked out.

Much like a shower strainer, an ounce of prevention here will save everyone a lot of time hunched over a sink searching for lost hair (or even diamond rings).

The Shower

Onto the final component of the bathroom. The shower and bathtub are where all our cares get washed away and relaxation sets in (unless there's a faulty flange or valve).

So, let's start at the top. First, you have your shower flange, which is that silver disk that lies flat against the wall. This leads to the shower arm which connects to the shower head.

Plumbers' tape was all but made for this scenario. A little strip on both ends of the shower arm is a time-old maneuver that provides a tiny bit of peace of mind.

Then, it's down to the faucet. Within the wall, there's a valve that releases the water. This connects to a cartridge which leads to the stop tube. So, the valve, cartridge, and stop tube are the major components that control the flow of water.

At the end of the stop tube, we have another handy escutcheon (a.k.a. flat piece of metal) which leads to the handle. Of course, when it's bath time, we also need to refer to the spout at the bottom of all this.

The tub spout connects to its own valve in the wall, pretty plain and simple. The spout will come with all the working parts to allow you to pull up the drain and fill the tub to your heart's content.

The final connecting piece is the drain or drain stop. This will pull up or down as needed. But, no matter what you do, be sure to invest in a little forward thinking and place a hair catch over the drain.
