Quick Answer: How To Install A Toilet Flange

Should toilet flange be flush with floor?

The toilet flange needs to be on top of the finished floor. Meaning the bottom edge of the flange needs to be on the same plane as the toilet. So if your toilet sits on the tile, the flange needs to be on top of the tile too.

Does toilet flange go inside or outside pipe?

This toilet flange is designed to glue on the inside of the pipe or expand inside the pipe. Leave the old toilet flange right in place and glue on the new one at the right elevation for the floor, if it’s plastic. The flange should be sitting with the bottom edge flush with the top of the floor.

Should toilet flange be flush with tile?

The bottom of the flange must be flush with the tile, no gaps, or it could end up too high. You don’t want a large wax depth from having it too low and if it is too high, the toilet will rock. The seal is engineered to work best with the flange on top of the finished floor.

How far should toilet flange be above finished floor?

Check the Flange Height With the toilet removed, you can see the toilet flange and measure its height above the floor. The optimum flange height to aim for is 1/4 inch above the finished floor. This typically allows for almost any type of wax ring to be used and still ensure a good seal.

How far should a toilet flange be from the wall?

Standard drywall is 1/2 inch thick, so the plumber should set the toilet flange at least 15-1/2 inches from the center of the flange to the wall framing. The standard distance from the back wall is 12 inches, or 12-1/2 inches from the center of the flange to the wall framing.

Can toilet flange be lower than floor?

In a typical toilet installation, the floor flange that sits inside the drain opening below the toilet should be positioned so that its bottom surface rests flush against the finished floor or no more than 1/4 inch above or below the floor.

Does a toilet flange fit inside 3 inch pipe?

This toilet flange is designed to fit INSIDE a 3″ HUB, not inside a 3″ PIPE. (3″ pipe has a 3.5″ OD and 3″ ID).

Do you tile before installing toilet?

The bathroom fitters are unanimous—if you’re looking for a high quality finish, with a better seal against water damage, then always tile the floor first. The floor will be sealed a lot better with the tiles being laid under the toilet.

Can a toilet flange be too high?

When your toilet flange is too high, your toilet may leak water and rock back and forth when used. Both the leaking and the rocking can warp or break the floor. A leaking flange can also rot the subfloor and lead to the accumulation of mildew and mold.

Should I caulk around toilet flange?

Caulk prevents a fouling area. If mop water, bathtub water, or a less pleasant “bathroom liquid” gets underneath the toilet, there is no way to clean it up. Caulking around the base of the toilet will prevent this from happening.

Does vinyl plank go under toilet?

You can put vinyl plank flooring under the vanity, under the toilet, and around the bathtub. Vinyl planks must go under the toilet to offer support and vinyl planks can be installed around the bathtub with caulking.

What is the rough in distance for a toilet?

The toilet rough-in refers to the distance from the finished wall to the center of the toilet’s floor drain or waste outlet. Most toilets have a rough-in of 12 inches, although it’s not uncommon for older homes to have an unusual size such as 10″ or 14″.

How is toilet rough in distance measured?

The rough-in measurement of a toilet refers to the span between the wall behind the toilet and the center of the waste pipe. To measure the rough-in for your toilet, measure from the wall behind the toilet to the middle of the bolt caps (the caps holding your toilet to the floor).

What is the difference between a 10 and 12 rough in toilet?

When a toilet with a 10-inch rough-in is placed in a 12-inch rough-in space there will be 2 inches of open space between the tank and wall. However, the extra inches will cause the tank to be further away from the shutoff valve on the wall, so a longer connector may be needed to reach effectively.

Does a toilet have to be perfectly level?

2 Answers. There are purists out there that may say it must be level, but if it looks good setting there, I would let it set on the floor with no shims. It should not affect the operation of the flapper or valve that flushes the toilet.

Does a toilet flange need to be screwed down?

The flange should be fastened to the floor. Dry fit the toilet to make sure it doesn’t rock. If it does rock, use shims to prevent rocking – just tightening the bolts probably will not stop the rocking but will risk cracking the toilet or breaking the flange.

Is 3 inch pipe OK for toilet?

In new construction, 4-inch drains can be installed from every toilet, or you can run a 3-inch drain line from a toilet to the home’s main 4-inch drain pipe — the line running from the house to the sewer or septic system. Older homes may have only 3-inch drains, so that’s what you have to work with.

What fits inside 3 PVC?

What is the diameter of a toilet flange?
