Does toilet flange go on top of finished floor?

Last Updated: 4th March, 2020

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.

Then, 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.

One may also ask, 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 flush with the finished floor, or no more than 1/4 inch above or below the floor.

Considering this, how far off the floor should a toilet flange be?

The optimum toilet flange height is approximately ¼ inch above the floor to achieve the best seal and overall fit.

How do you raise the toilet flange after tiling the floor?

A better solution is to raise the height of the flange.

  1. Measure the distance from the top of the toilet flange to the top of the finished tile floor.
  2. Purchase a toilet flange extension ring thick enough to raise the toilet mounting surface so that it's approximately 1/4-inch above the level of the finished tile floor.

Should the toilet flange be on top of tile?

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. The spacing of the toilet exit "horn" and sealing surface is designed for this height.

Should I caulk around toilet flange?

Some people prefer to caulk all around the toilet and leave about a one-inch gap in the caulk at the back of the toilet to allow water to escape out in the event of a leak. It's already tough enough to caulk behind a toilet, so if this is what you want to do, God bless. Just don't go crazy with the caulk.

Does a toilet flange need to be screwed to the floor?

5 Answers. The bottom of the flange needs to be sitting flush with (or not more than 1/8" above) the finished floor or else the toilet will rock. The flange should be fastened to the floor. Dry fit the toilet to make sure it doesn't rock.

Does a toilet flange have to be level?

The toilet should sit on the floor over the flange and still have a little room above the flange for wax to make the seal - it must be shimmed to sit flat, if it rocks (before you install the wax ring). If the toilet sits ON the flange, you won't be able to keep it sealed properly.

Can toilet be installed without flange?

2 Answers. The flange and accompanying bolts hold the toilet firmly to the floor and keeps the seal between the toilet and the floor. Without the flange or if it is broken, he would have to attach the toilet to the subfloor with wood screws, and if the floor is rotting out, those won't last long.

What size wax ring should I use?

The wax ring should be compressed around 1/2 to 3/4 it's initial height once installed. If it will compress less, you need a taller ring. If it will compress more, consider getting one with a flange to limit wax extrusion into the drainage path. I always purchase the extra-thick ring with the flange.

Can you set a toilet on vinyl plank flooring?

If you're installing a new floor, pedestal sink, and toilet, you should install the laminate flooring first so it's under the sink and toilet. This makes it impossible for any caulking around the base of the sink and toilet to hold.

Is it OK to use two wax rings on a toilet?

You Don't Have to Use a Double Wax Ring
Plumbers have been using wax rings to seal toilets almost as long as there have been toilets because wax is waterproof, sticky and molds to any shape. It's messy, though, so manufacturers have come up with a toilet wax ring alternative made of rubber.
