How to Remove Your Toilet

The old toilet must be removed before you can begin installing the new one. The old toilet needs to be taken out and its pipes and fixtures disconnected. How then do you turn off the toilet? We’ll respond to the query in this section.

All things considered, depending on the state of the toilet’s fixtures and parts, the time it takes to remove a toilet ranges from 15 to 30 minutes. The procedures you must take to thoroughly remove your old toilet from the floor and sewage pipe are listed below. But if you’re still confused, you can always ask the experienced plumbers for advice; they’ll be pleased to assist you.

Step 1. Turn Off the Water Valve and Drain the Toilet

Start by donning your rubber gloves and getting ready to go. The water valve needs to be shut off and the toilet cistern needs to be drained first. You must flush the toilet to ensure that the cistern is empty before performing the latter. The cistern lid should be removed in order to use sponges, cloths, or towels to absorb any remaining moisture or water that may still be present. When you’re prepared, move on to the following action.

Step 2. Disconnect the Water Supply

Make sure to turn off the water supply because you must work in a dry atmosphere. Find the supply valve in your house, and turn it off while you are installing and removing the toilet.

Step 3. Remove the Toilet Cistern 

The tank that holds the water used for flushing is known as the toilet cistern. Prior to separating the rest of the toilet body, you must remove it. One-piece toilets, where the cistern is physically affixed to the toilet itself, are exempt from the requirements of this stage. Therefore, it’s critical that you are informed of the type of your toilet and cistern so that you can take the appropriate action to remove it and install a new one.

The cistern lid should easily come off when lifted, so start there. If the toilet has a flush down button instead of a lever, it may be more tightly bonded to the cistern. Otherwise, it may not. The fasteners at the cistern’s base must next be unscrewed using a screwdriver. If you discover that your flushing mechanism needs to be replaced, replacing your flush button is an entirely different subject.

You can move on to the following step once you have successfully unscrewed them. Use a set of pliers or a wrench to assist you if the bolts are rusted, worn out, or tightly screwed on and making removal difficult.

Step 4. Unscrew the Mounting Nuts

The fixtures that secure your toilet to the floor are the mounting nuts on the toilet. As noted in the previous step, removing these nuts may be difficult if they are rusted or old. In this case, consider using a screwdriver or wrench to help you loosen and unscrew the nuts. As they may have been screwed on years ago and are consequently difficult to move out of place, this may need some effort on your side.

Step 5. Cut Through the Caulk and Pull the Toilet Up

Most toilet bases are secured to the bathroom floor by plumbers using silicone or caulk. Therefore, you can scrape this substance from the toilet’s foundation using a putty knife or utility knife. Once you’ve finished, clean the toilet’s base with an old cloth or rag.

The old toilet may now be removed because you have already undone the mounting nuts in the previous step, cleaned the caulk, and cut through it. Take care when lifting it because the toilet body might be pretty heavy.

Step 6. Remove the Old Wax Ring

You must unplug the toilet body from the sewage pipe before fully raising it up to remove it. The old wax ring that links the toilet to the sewer pipe and your drainage system must be taken off in order to accomplish this. Use a putty knife or utility knife to effectively and fully scrape off this pretty sticky stuff. This wax ring is a useful insulator since it stops leaks from the toilet.

Step 7. Check the Flange and Your Bowl Bolts

The toilet’s flange serves as a stabilizing floor mount. It is usually constructed from PVC, copper, steel, or brass, and it is joined to a metal or plastic ring by a bolt. A wax ring is used to seal it to the toilet’s drain in order to stop leaks.

Once the flange has been located, you can unscrew it to disconnect all of the toilet’s parts that were attached to the floor or plumbing. Your old toilet has been successfully removed and disconnected!

How to Fit a Toilet

Depending on your degree of DIY expertise, installing a toilet can take anywhere between one and four hours. Any new toilet installation requires advance planning and, in essence, working backwards from old toilet removal.

So, if you’re unsure how to install a new toilet, read on for some simple instructions.

Step 1. Install the New Mounting Bolts and Wax Ring

Keep in mind that you should still turn off your water supply while working to prevent drips and leaks that could cause a mess. You can now install your new toilet, which ought to have brand-new mounting bolts. Where the old holes are, you must fasten these to the ground there. In order to prevent water leaks, you must also place the new wax ring on the sewer pipe. It is pretty sticky, so take caution.

Step 2. Fit the Toilet and Tighten the Nuts

Make sure the bolts line up with the holes by carefully and slowly hovering the new toilet’s body over them. You must tighten the bolts with the nuts when they have emerged from the holes. We may go on to the following stage now that your new toilet is safely attached to the floor and sewage pipe.

Step 3. Install Your New Cistern

Installing your new cistern is now necessary. However, keep in mind that one-piece toilets, in which the cistern is affixed to the toilet itself, are exempt from the requirements of this stage. Using the tools and equipment mentioned above, pick up the cistern and fasten it to the toilet body.

Step 4. Connect The Water Supply

You are now prepared to turn on the water supply after securing your toilet in place. Do so while being aware that there might be leaks.

Step 5. Turn On the Water and Check for Leaks

Making ensuring that none of your labour is wasted is essential. You should therefore check for drips and leaks. To make sure that no water is dripping into the bathroom floor, flush the toilet several times.

How Long Does it Take to Replace a Toilet?

That largely depends on your level of expertise and experience, as well as the kind of toilet you have. It ought to be simple if you’ve done it previously. But if it’s your first time, it may take anywhere between one and four hours on average, depending on how complicated the task is.

How Much Does it Cost to Install a Toilet?

Don’t worry if you’re not sure that you can install a new toilet and remove an old one. You can always seek assistance from experts. On average, toilet installation services cost £98 per hour. It can take two to three hours, depending on how complicated the task is. The cost also differs according to whether the job must be done on the weekend or in the evening.

As these are not the final costs and may change, this is only a rough estimate of what you might have to spend. However, if you’re a member of the Fantastic Club, you can get a nice discount.


It doesn’t need to be a challenging or intimidating task to replace an old toilet with a new one. You’re ready to start this DIY project as long as you have the necessary tools and supplies available. In the end, all you’ll need to do is follow the instructions in order to do the task by yourself.

This will not only help you avoid a major mess, but it will also make it possible for you to complete the task more successfully.
