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.
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.
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.
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
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
the sink drain is prob.in the wall.you 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.
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.
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.
