Toilets can be fragile and sometimes be awkward as the way they are built can be confusing.

Therefore, if you are looking at installing it yourself, you need to know what you are doing as you don't want to break it and need to replace your new toilet straight away.

This article will also help you know what to do if you are doing a toilet installation on a budget, as the price of having to install it can sometimes be expensive, so if you want a cheap toilet installation, this article will give you all the information you need to do so!

What Is Toilet Installation?

Toilet installation is when you need to put a brand-new toilet in your home. This could be because you have broken your old toilet and need to replace it with a new one, you have just moved into your brand-new home and a toilet is not installed, or it's part of a full bathroom installation.

As toilets are important for humans and every household has a toilet, knowing how to install or where to go to get a new toilet is very important because you will need a new toilet at some point in your life.

Knowing when to get a new toilet can be stressful as toilet repairs can happen a lot. However, multiple signs tell you that you should get a new toilet.

If your toilet keeps blocking, check whether wipes or other bathroom waste are being flushed before deciding to replace it.

Or if it begins to wobble, then it could just be a case of loose screws. Tightening the bolts and making sure everything is in the right place is simple for a plumber.

However, wobbling can indicate a more serious condition. It's possible that the floor beneath the toilet is deteriorating or water damaged, meaning it's time for a new toilet.

The ceramic toilet can remain in good condition for many years, while worn parts inside the cistern can often be replaced without changing the whole toilet.

Toilet installation is also popular because most toilets end up having problems such as leaks, not flushing properly, flush handles breaking, and weird smells. Therefore, in some cases, people just decide to buy a new toilet and install it themselves rather than ringing a plumber to solve the problem.

Types of Toilets

Here are the different types of toilet available to choose from:

Dual-Flush Toilets

dual flush toilet

These toilets have a half flush and a full flush option on the flush button, which is where the name comes from. We use the half flush for liquid waste and the full flush for solid waste.

Pros

  • ✔ Use less water.
  • ✔ Can reduce water bills if your home has a water meter.
  • ✔ Better at cleaning the bowl per flush.
  • ✔ Eco-friendly.

Cons

  • ✖ Wrong button can get pressed, or both at the same time.
  • ✖ Repairs can be trickier with a dual flush valve.

Back-to-Wall Toilets

Back-to-wall toilets are a fashionable option. They save space, are pleasing to the eye, and are easy to clean and maintain.

The toilet bowl sits on the floor against the wall, while the cistern is concealed behind a piece of furniture or within the wall.

These toilets are cheaper and easier to install than wall-hung toilets.

Pros

  • ✔ Pipework and cistern are hidden.
  • ✔ Easier to clean around the outside.
  • ✔ Flushing noise can be slightly muffled.
  • ✔ Bathroom looks less cluttered.

Cons

  • ✖ Installation can be more expensive.
  • ✖ Repairs are through an access panel.
  • ✖ Needs more planning.

Wall-Hung Toilets

These toilets are mounted on the wall and are elegant and trendy. In addition, because the cistern is built into the wall, they conserve room. These toilets can be costly and time-consuming to install.

To complete the job, you'll need to employ a qualified plumber and possibly a handyman.

The total cost of the wall-hung toilet rises as a result. It's quite simple to sterilise the unit, and it does have certain benefits.

Although they are expensive, there is a variety of them and they are very aesthetically pleasing.

Pros

  • ✔ Modern and contemporary look.
  • ✔ Easier to clean the floor.
  • ✔ Can make small bathrooms look bigger.
  • ✔ Good for accessibility, as height can be set to suit you.
  • ✔ Hides pipework.

Cons

  • ✖ More expensive and difficult to install.
  • ✖ Repairs are more awkward.

Close-Coupled Toilets

close coupled toilet

Close-coupled toilets have the cistern linked to the toilet bowl, resulting in a single, streamlined unit that incorporates both vital components.

Many close-coupled models conceal the pipework, and compact designs are available for smaller bathrooms. These toilets are often the standard budget options. They are very good quality, and they can last for a long time.

Pros

  • ✔ Lots of choice and styles.
  • ✔ Budget options available.
  • ✔ Simple installation.
  • ✔ Good for small bathrooms.
  • ✔ Easy to repair.

Cons

  • ✖ More to clean around.
  • ✖ Pipework remains visible on some models.

High-Level Toilets

High-level toilets can provide a lovely traditional touch to your bathroom. They have a high-up on-the-wall cistern that must be strong or secured to avoid any problems.

High-level toilets have a long chrome flush pipe with a long pull chain flush for an elegant design.

Pros

  • ✔ Great for a traditional, heritage look.
  • ✔ Strong flush.
  • ✔ Good for tall ceilings.

Cons

  • ✖ Noisier flush.
  • ✖ Needs the right wall and ceiling height.

Low-Level Toilets

low level toilet

They give your bathroom a more vintage look, like the high-level toilet. Because the cistern is installed at a lower level, the flush pipe is shorter. A traditional lever controls the flush mechanism.

Pros

  • ✔ Looks traditional.
  • ✔ Strong flush.
  • ✔ Good for awkward layouts.

Cons

  • ✖ More to clean around.
  • ✖ Trickier installation.

Advantages and Disadvantages of Installing a New Toilet

When installing a new toilet, the idea seems like a long and expensive process. However, with every task comes advantages and disadvantages.

This section of the article will outline the positives of replacing your old toilet and the negative aspects.

Toilets aren't built to last forever, and they'll eventually need to be replaced when a single significant problem or a series of minor issues necessitate repairs that aren't worth the money the plumbing work will cost.

So, when your toilet constantly needs repairs, it is probably time to install a new one. However, do your research and find the best toilet for you!

Pros

  • Replacing an older toilet with a water-efficient model can reduce the amount of water your household uses.
  • Modern toilets use no more than 6 litres for a full flush, while older models may use considerably more.
  • Dual-flush toilets let you use a smaller flush when a full one is not needed.
  • If you have a water meter, using less water can also help reduce your water bills.
  • Clogs and leaks can build up in terms of maintenance costs. Problems like a damaged cistern can leave a toilet completely worthless, needing replacement to restore the operation and prevent water damage to your property.
  • So, rather than wasting time and money on a broken toilet, changing the fixture is a long-term solution with a one-time expense that ensures your toilet is tailored to your needs and will perform properly for years to come.
  • Choosing a toilet that complements the style of your bathroom may transform the space, improving its appearance.
  • If you have an older toilet, you may be more likely to have a flood. Of course, you could be taking good care of your "bowl," but with time, portions may disintegrate, resulting in one of the most unsettling experiences you'll ever experience.
  • Toilets nowadays are more water-conscious but will also be equipped with the most cutting-edge plumbing technology. This will not only provide you peace of mind, but it will also keep your home dry and plumbing in good working order!

Cons

  • The price of installing a new toilet is a factor because toilets are not cheap.
  • When moving and installing your toilet, use caution. Almost all are made of vitreous china or porcelain, and if dropped, they will split or shatter.
  • A toilet has been destroyed by more than one DIYer after it was dropped by mistake. Therefore, make sure you are aware of what you are doing.
  • When removing the toilet, you can cause damage to yourself as they are heavy and awkward to pick up. Therefore, if you are doing it yourself, you will need a helper there if you need help carrying the heavy toilet.

How Much Does It Cost to Install a New Toilet?

installing toilet

Installing a new toilet is a common home remodelling project that can improve your comfort and make your bathroom look more appealing.

There are several factors to consider when considering the cost of toilet installation, such as the type of toilet you are installing, the current plumbing in your bathroom, the type of cistern you are using, and the significance of preparations.

It's crucial to talk to a few different tradespeople while completing your research to ensure you're getting fair and competitive prices. You can get multiple toilet installation quotes from local plumbers using MyJobQuote, that are fast, free, with no obligation to go ahead.

It's also a good idea to request a complete breakdown of all prices, including labour and supplies, so you can compare them and see where costs differ.

How to Install a Toilet

Before the Job

  • Get to Know the Parts — The first step when installing a toilet is to know the different parts of the toilet and which ones connect. This makes it easier, so you know which part comes with each step.

During the Job

These steps cover fitting a standard close-coupled toilet after the old toilet has been removed. Check the instructions supplied with your model before starting.

  • Turn Off the Water — Make sure the water supply is turned off before you begin. The cistern must also have an isolating valve so the toilet can be turned off separately if needed.
  • Block Sewer Gas — Temporarily plug the open soil pipe with a rag to reduce sewer smells and stop small parts falling inside.
  • Position the Cistern — Place the sealing washer between the cistern and toilet pan, then secure the cistern using the fixings supplied. Tighten the fittings carefully without overtightening them.
  • Position the Toilet — Put the toilet in place and check that the pan connector lines up correctly with the soil pipe. Mark the fixing points once you are happy with the position.
  • Drill the Fixing Holes — Move the toilet out of the way and check for hidden pipes or cables before drilling. Use suitable plugs and fixings for the floor and wall.
  • Secure the Toilet — Remove the rag from the soil pipe and fit the pan connector, then position and secure the toilet. Tighten the fixings carefully to avoid damaging the ceramic.
  • Reconnect the Water — Connect the water supply to the cistern and fit the flush button or handle following the manufacturer's instructions.

After the Job

  • Final Checks and Flush Test — Turn the water back on, open the isolating valve, and let the cistern fill. Check the water reaches the marked level in the cistern, adjusting the fill valve if needed. Then, flush the toilet and inspect all connections for any leaks. Once any surrounding tiling or finishing work is complete, fit the toilet seat.

Then your toilet is installed! There are quite a few steps to follow. However, DIY can be done when installing a toilet if you follow them easily. If it is too hard or putting you at risk, you can hire a tradesperson to help.

How Long Does It Take to Install a Toilet?

Whether you will DIY or hire a tradesperson to install your new toilet, the timescale varies. A simple procedure like replacing an existing toilet with an identical (or extremely comparable) new unit can take a plumber or tradesperson anywhere from 2 to 4 hours.

However, if you are trying to do it yourself, the timescale will extend as experience and knowledge make the job quicker. So, if you have never installed a toilet, then the process might be longer as you are also learning.

The different types of toilets influence the timescale as some are easier to install and others include different parts. The job will take longer if replacing the pan connector or repairing the soil pipe involves lifting tiles or opening up the ceiling below. Removing the old toilet will take more time as you have to unscrew and clean out the old screws.

Before installation, two-piece toilets must be constructed. It usually takes less than 15 minutes, but there's always the chance that a gasket between the bowl and the cistern, or cistern bolt gaskets, will fail to keep the water in and cause leaks. It takes longer to replace defective gaskets.

Type of Toilet Average Time
One-Piece Toilet 1.5 to 2 hours
Wall-Hung Toilet 2 to 2.5 hours
Low-Level Toilet 2 to 3 hours
High-Level Toilet 3 to 4 hours
Close-Coupled Toilet 30 to 40 minutes

Building Regulations & Planning Permission for Toilet Installations

Building regulations and, where required, planning permission approval, are extremely important as you don't want to get in trouble with your council.

They are also important because if there are building regulations, then that means there are hidden risks when installing a toilet.

You don't want to damage anything or harm yourself when you can just follow regulations and, where needed, get permission to install a new toilet.

installing toilet

In England and Wales, replacing a toilet in the same position will not usually need building control approval if the drainage stays unchanged and the new toilet uses no more water than the old one. However, the installation must still meet building regulations.

If you are moving the toilet, adding another one, or altering the drainage, arrange building control approval before work starts or use a plumber registered with a competent person scheme that covers the work.

Scotland and Northern Ireland have separate requirements, so check with your council before starting.

As for planning permission, fitting or replacing a toilet inside your home will not need it. However, if your home is listed, check with the council whether the work needs listed building consent before you begin.

How to Clean and Maintain a Toilet

Cleaning toilets is a chore that few people enjoy. Therefore, although it is a job you hate, it is also essential.

Regular toilet cleaning removes hazardous bacteria as well as unsightly mineral or soil accumulation. Keeping your toilet clean will help prevent issues if you keep it in a brand-new condition!

However, like with most household chores, cleaning your toilet regularly will make the job go more smoothly the following time.

To keep these items apart from the rest of your cleaning products, put them in a bucket. Cleaning the sink with the toilet sponge or washing dishes with the same rubber gloves is not a smart idea.

To start your cleaning process, include all of these items in your cleaning journey:

  • Rubber gloves.
  • Scrub sponge.
  • Toilet cleaner (vinegar also works!)
  • Toilet brush.
  • Disinfectant spray.
  • Cloth.
  • Paper towels.
  • Pumice stone.

The best way to clean your toilet comes in five simple steps. It is the easiest method and keeps your toilet spotless every time. It is also a popular way to clean your toilet as none of the items needed is expensive.

  1. Begin by scrubbing the toilet bowl with a toilet cleaner and allowing it to soak. Pour a cup of vinegar into the toilet bowl if you're not using toilet cleaner. Swish the cleaner about the bowl with a brush as quickly as possible to scrub the bacteria off.
  2. If the toilet is very filthy, wipe it down with paper towels before tossing them in the bin. This will allow the outside of your toilet to look brand new! Spray an all-purpose disinfectant over the toilet's outside as the cleaning solution soaks in.
  3. After that, wipe the toilet's outside using a cleaning sponge. While you're there, pay attention to the toilet's base and floor. Remove the seat and clean it separately if you have a modern toilet with a quick-disconnect toilet seat.
  4. After cleaning the exterior, clean the toilet bowl with a toilet brush. Use a pumice stone to get rid of any hard water rings or stains.
  5. Do you know where the water rushes out beneath the rim? Many people overlook this since it is out of sight. Don't overlook this location! Clean the bottom of the rim with your brush or sponge.

Using this method allows every part of your toilet to be cleaned and looking brand new, which is why it is the best.

There are other methods to clean your toilet that you can see on TikTok as many people have created a cleaning account to show ways to clean your home, including your toilet.

Questions to Ask When Hiring a Toilet Installation Specialist

1. What Are Their Average Costs to Install a Toilet?

This will allow you to know how much you are going to be spending just to install the toilet. If you do your research and ask a few toilet specialists, you will be given an estimate of what you are paying.

2. Do They Have Any Previous Employment References?

If you discover a toilet specialist who is prepared to show you examples of their previous work, take the time to look at their previous work images if they have them.

It also reduces the chances of being scammed as they show you their past jobs and reduces worry because you know the job will be done correctly.

3. What Kind of Guarantee Do They Offer for Their Work?

Make sure you receive a formal guarantee of work or examine their usual guarantee. It's even better if their guarantee is backed by insurance, as you'll be protected if the tradesman goes out of business.

It's critical to review the promises because you don't want to discover an issue a few weeks after your normal guarantee period has expired, and it will cover the costs if the damage comes up again.

FAQs

How Long Do You Need to Wait to Use the Toilet After Installation?

If silicone has been used around the base of the toilet, allow it to fully cure before using it. This is usually around 24 hours, although drying times vary, so check the sealant manufacturer's instructions.

Which Toilet Is the Best?

The best toilet for your home depends on your bathroom layout and the style you prefer. Close-coupled toilets are the most common choice in the UK, while compact wall-hung or back-to-wall models can work well in smaller bathrooms.

What Are the Signs That You Need a New Toilet?

Here are six different signs that could mean you need a new toilet:

  1. Constant repairs.
  2. Cracks in the bowl or cistern.
  3. Constant running.
  4. The trouble with flushing, clogging, or overflowing.
  5. Wobbling toilet.
  6. High water bill.

What Is a Close-Coupled Toilet Installation?

Close-coupled toilets link the cistern and the toilet bowl, and many also conceal the pipework.

Is DIY Possible?

While a toilet installation might be a do-it-yourself effort for competent homeowners, keep in mind that mistakes can be costly. Errors can result in floor damage, leaks, and other issues that may necessitate the services of a plumber. It's a good idea to hire a plumbing specialist in your region just to be safe.
