Cement is a common material in construction. Having it used as a fix to a toilet may seem solid, but uninstalling it may be grueling. Also, hiring a plumber may cost you more than expected. The professional installation costs start from $224.

Cement generously whacked around a toilet can damage the bathroom floor while removing the toilet. Tiles can be cracked or scratched. The good thing about a toilet that is properly maintained and installed even on the cemented floor is less damage during removal.

Before pulling up the toilet, prepare a large trash bag about the size of the toilet to catch up on the leak while transporting it out of the house.

Here's the list of tools that should come in handy when removing the toilet:

  • bolt wrench
  • plastic scraper
  • thin and semi-large chisels
  • sponge
  • bucket
  • rag
  • large trash bag
  • small hammer
  • tape
  • vacuum

Cleaning Up After Removing The Toilet

There's no way you will leave traces of the toilet. There are more parts beneath the toilet. And before installing a new one, make sure it's clean and spot on for another installment. Here are some tips on how to clean after removing the concreted toilet to the floor, starting from the inner flange of the toilet :

  • Remove all the wax stuck on the inner flange without dropping it into the drain pipe with a plastic scraper.
  • Examine the flange for cracks or breaks. If there is, replace it.
  • Slowly remove the bolt screws remaining by turning and twisting them around.
  • Tape the open drain pipe before chiseling the remaining cement on the bathroom floor.
  • Use a medium-large chisel to scrape away the remaining cement. Be careful not to scratch the tiles.
  • Throw out the chunks of cement and vacuum to clean.
  • Dispose of the old toilet at a nearby junk shop.

Installing A Toilet to Cement Floor

Prepare the area where to put the toilet starting from the pipe. There should be 3 inches diameter drainage pipe ascending from the concrete and a water line through the nearby wall. Make sure to even the platform where you will put the toilet. Use a concrete grinder.

There are two parts to installing a toilet on the cement floor. Follow the steps below to install a toilet on the cement floor, starting from placing the floor flange:

Installing A Floor Flange

  1. Sample fit the floor flange on top of the drainage pipe to achieve a flat base.
  2. Apply glue around the tip of the drainage pipe and the floor flange.
  3. Seal it together.
  4. Install evenly and measure to check.
  5. Fasten the floor flange screws using a masonry drill.
  6. Blow out the dust in the small spaces and holes caused by the drilling with a dust blow pump.
  7. Immediately wipe the dust or block the dust from puffing with a blanket.
  8. Lock the bolts into the slots of the floor flange. It should be sticking out.

Installing The Toilet

  1. Dry fit the toilet to see if the bolts don't hobble and fit perfectly.
  2. Take off the toilet and place the wax ring on top of the floor flange.
  3. Install the toilet fitting with the wax ring and tight with the two bolts sticking out from the toilet base.
  4. Place the nuts and caps. They come with a new toilet to cover the sticking bolts.
  5. Connect a small hose at the base side to the water valve by fitting in with a wrench or with your bare hands.
  6. Open the shutoff valve to test the water line of your toilet.

Can You Put A New Toilet Flange Over An Old One?

The simple answer is no. All the more if the old toilet flange is broken or cracked. It damages the flooring of the bathroom. It also makes the toilet uneven and unstable. Thus, it is more likely to change the old flange to a new one. Clean all the wax around and unfasten the worn-out flange.

Should I Put The Wax Ring On The toilet Or The Flange?

Toilet Installation

Put the wax ring on the flange after re-checking that the bolts go through the holes of the toilet base. Place it on top of the flange and install the toilet pushing into the wax ring. Push until tight to prevent leaks. 

How Do I Know What Size Wax Ring I Need For My Toilet?

Measure the diameter of the old wax ring with a tape measure. You have a choice to measure the elbow neck of your toilet to know the old ring's dimensions. It's the base opening of your toilet. For the thickness, use an extra thick wax ring if the flange is lower than the floor level. If not, use a standard wax ring.

Is There Something Better Than A Wax Ring?

A wax ring has always been a reliable tool among plumbers for years. With upgrading bathroom floors, sometimes wax may be the best for your toilet. The wax on the ring may melt if you have a heated bathroom floor. A new opposite seal is a wax-free seal. It is reusable, unlike the wax ring.

How Often Should You Replace Toilet Seals?

A wax ring usually lasts up to 30 years. It prevents leakage and traps sewer odors inside. You will also need to replace it when re-installing or replacing your toilet. While a wax-free seal may give you a guarantee of 10 years, it doesn't have that long lifespan, unlike the wax ring.

How Tightly Do You Tighten A Toilet To The Floor?

There's not a definite way to tighten a toilet to the floor. But, the standard is to twist the fastening bolts until there's no resistance. Try to flutter from side to side after one or two twists of bolts and until the toilet seems unstable.

Why Do Toilets Leak At The Base?

A leak indicates an unstable or lousy installation or a damaged part. Find out the possible reasons why toilets leak at the base:

  1. The bolts are loose.
  2. Worn out wax rings.
  3. Detached water line.
  4. Humid room resulting in water oozing down from the bowl porcelain to the foot of the toilet.

In Closing

A toilet cemented to the floor can be a DIY project with complete tools and instructions. Wear eye protection and gloves for safety. Handle-with-care your toilet. And, it will serve you years of warmth and no leaks.
