On a standard toilet in America the drain is 12 inches from the back wall to the center of the drain.

You don't have to have one, it just makes it a little easier. As long as the drain is flush with the floor, you can drill into the concrete and us anchors to hold the toilet down. The down side is that they tend to corrode over time and become stuck in the concrete. If you ever have to remove the toilet, they can break and that makes putting the toilet back harder. You can just bolt a mounting ring to the floor and use regular toilet bolts to hold the toilet. These can be easily replaced if needed.

First determine what you are going to install as the shower unit. If there is to be no shower unit and it will just drain through the concrete floor, then it will be flush with the floor. If you are installing a unit, then you need to look at the unit to determine the distance obove the concrete to place the drain.

If you reduce the soil connection to 2" and install a trap

None. It is the same as a normal toilet, 3" or 4" drain.

Probably not. There is no vent for that drain, it did not need one for a floor drain. A toilet is trying to push against the air pressure in the drain.Normally a decent plumber will install a floor drain with in 15 feet of a vented line or will vent the FD in case irt exceeds the 15 ft ruleA Floor drain can be as small as 2" diameter and thus it is undersized for a toilet and a floor drain alread has a trap and a toilet would thus be drouble trapped

A shower drain is 1 1/2 or 2 inch and a toilet needs to be either 3 or 4 inch.

You need at least a 3 in. pipe -- shower is 2 in. pipe

You dont. A tub drain is too small for a toilet drain. You need to hire a professional to find a main line 3" or bigger to tie into for a toilet drain.

No, a tub drain is too small for toilet plumbing. Toilet drains needs at least a 3" drain line and vented.

Usually toilet flange is glued down onto plastic drain pipe. There is a toilet flange that can be glued inside of plastic drain pipe also.

the sink drain is the would have to get a wall mount commode,or install drain in floor and plug drain in wallAnswerYou also need a 3 or 4 inch drainpipe.Ans 3 - You can do this if you fit a new 3" drain to the main pipe and run it to a toilet flange where the sink is.

The toilet flange sits on the floor and connects the toilet to the drain. It should connect to both.

A toilet has to be vented otherwise you are trying to force liquid against the air in the drain and it is pulling against a vacuum. It will never flush right.

If you have a drain available. You may need to chip some concrete around the drain to install the bottom half of the drain. With that in place, set the shower over it and the top piece screws into the drain to form a seal. You can build a 2x4 frame and raise the shower up enough to run a drain to a sump or a floor drain.

Yes, as long as drain line is sized properly for toilet. 3" drain line would be minimum pipe size for toilet drain line to tie into.

If you are asking how far the drain is from the wall behind the toilet, it is 12 inches from the center of the drain to the wall behind the toilet.

The gurgling in your kitchen sink drain trap is because your drain system from you upstairs toilet is not vented properly. As the flow drops down the vertical drain pipe from the upstairs it sucks the water out of your kitchen sink drain trap and causes it to gurgle. It could drain the kitchen sink trap and allow sewer gas to flow into your kitchen. The fix is to either install an Air Admittance Valve (AAV) in your kitchen sink drain plumbing or properly vent the upstairs toilet drain.

As close as possible is best, but there just has to be a vent so that the air that is in the line has somewhere to go so that the liquid isn't trying to compress it. The closer the vent is to the toilet, the better it will flush.

If you just plan on putting the toilet on top of the floor drain the answer is no. The floor drain if it leads to a septic system or city sewer would have a trap in the line which will not work with a toilet. Depending on the size of the pipe 3" minimum you could cut the floor and tie a toilet into the line. It would also have to be properly vented. I would consult a plumber on the job. Its also possible that the floor drain just goes to a dry well which could not be used. Even if it could not be used there are other ways to install a toilet below the septic or sewer line.

Change how? Move the location, you bust out the concrete and move it. Replace or repair the flange that the toilet hooks to. Cut the existing flange off flush with the floor and install a new repair flange. They can be brass or steel. You can use a PVC one that fits in the drain and seal it with a wax ring under it and screw it to the floor. If you are working with cast iron flange and the slots where the bolts are supposed to go is broken out, they make a repair piece for this. It is a 3/4 inch wide by 3-4 inch long crescent shape piece that slides under the flange and the bolt that holds the toilet fits into it. You may have to chip out a little concrete along the edge to get these under the flange.

Yes as long as the drain has a trap and is vented

The bolts that come from the drain and run to to toilet help to alaign proper drainage and seal the toilet. You do not want to do the bolts set in cement idea...

A toilet will overflow when there is a blockage in the drain.

Yes. It is how the toilet is attached to the drain line.
