If the base of the new toilet is shorter than the distance between the rear bolt holes and the wall, it should fit. In small bathrooms where space is tight, also measure from the sides of the flange bolts to the sidewalls or other objects to assure side-to-side clearance.
Confirm that the base is stable and level by carefully rocking it from side to side and back to front before you bolt the toilet down. If it does not sit perfectly flat, it will rock and is more likely to leak over time. To correct this problem, slip toilet shims between the base and the floor to stop the rocking.
It boils down to something much simpler — size. That's right, not every toilet fits in every bathroom.
Most toilets will have a 12-inch rough-in. Toilets with a 10- or 14-inch rough-in measurement are a little less common, so you might have less of a selection of toilets of this size. If you're replacing an existing toilet, look for a replacement toilet with the same rough-in.
Most toilets have a 12-inch rough-in or hole, but some have 10- or 14-inch holes, which means that not all toilets fit all setups. Knowing how to measure the rough-in is essential, so you purchase a toilet that fits the existing drain hole.
If the base of the new toilet is shorter than the distance between the rear bolt holes and the wall, it should fit. In small bathrooms where space is tight, also measure from the sides of the flange bolts to the sidewalls or other objects to assure side-to-side clearance.
While some replacement toilet handles have a universal fit capability, others are designed specifically for toilets with front-, side-, or angle-mounting positions.
Most toilets will have a 2-inch drain or a 3-inch drain. Fluidmaster manufactures a standard or universal size of flush valves with flappers and are among the most common flush valves to be used.
While a 10-inch rough-in toilet can plausibly fit into a 12-inch rough-in (though a longer connector may be needed), the same cannot be said for using a 12-inch rough-in toilet in a 10-inch rough-in. A 12” rough-in toilet will not fit in a bathroom with a 10” rough-in size.
Standard toilet dimensions are typically between 28–30" deep, roughly 20" wide, between 27–32" high, and have a rough-in between 10–14". Now you can find the perfect toilet.
It's not too difficult to replace your old toilet, as long as you can connect it to an existing branch of the soil pipe. But if you want to add a new toilet in another part of your home, you should get a professional plumber to connect into the main soil pipe.
Another toilet shape myth that needs busting is the belief that you can't replace a round toilet with an elongated model. Again, this is false. The shape of the fixture doesn't affect its connection to the pipe.
Do all toilet seats fit the same? The simple answer is no, there are a range of different toilet seat fittings. Some are bottom fixing (fitted from beneath the fixing holes) and some are top fixing (usually required when there isn't access to the bottom of the pan, e.g. with a fully shrouded toilet).
Reasons to Caulk Around a Toilet
Moisture Prevention: Without caulk around the toilet base, external water can seep under the toilet, leading to floor and subfloor damage over time. This is especially important in bathrooms with wooden floors, as prolonged exposure to moisture can lead to rot and structural issues.
Position the new toilet wax ring on top of the toilet flange, ensuring it is centered. Want to know more about choosing the correct wax ring size, crucial installation tips, and other frequently asked questions?
It is fairly easy to tell if you have a properly sealed wax ring; your toilet will not wobble, will be stable, and will have no water leaks. A few specific things to check include the height of your toilet flange, the stability of the toilet, and whether the floor around the base of the toilet remains dry.
The standard rough-in dimensions for toilets is 12 inches. In older homes or small bathrooms, you'll sometimes see rough-in dimensions of 10 inches or 14 inches. Determine your bathroom's rough-in by measuring from the wall behind the toilet to the middle of the bolts on the base of the toilet.
Overall, selecting a 10-inch rough-in toilet offers a combination of space-saving benefits, versatility, and efficient performance, making it a smart choice for many bathroom projects.
To move the toilet more than just a couple of inches, you will have to demolish the concrete to access and relocate water and waste lines. Then you will have to rebuild the concrete foundation and replace the sub-flooring, flooring, and fixtures.
For most toilet installations, the rough-in is 12 inches. Sometimes in small baths or older homes it can be 10 to 14 inches.
To identify what size is needed measure the width of the flapper from end to end. If the flapper measures 3 inches across select a 2 inch flapper (like the 502 Fluidmaster model) if the flapper measures 4 inches across select a 3 inch flapper (like the 5403 Fluidmaster model).
There are various types of toilet handles to pick from. Firstly, remove the cistern lid and identify which type you have. If you are unsure which type you have then take a photo and contact one of our experts and we will recommend a suitable replacement.
Take off the toilet lid and set it aside so you can see the inside of the toilet tank. Find the flapper at the bottom of the tank. Check to see if the chain is connected to the flapper and handle lever. If so, you can simply pull up on the chain to lift the flapper which will flush your toilet.
