installing toilet in basement
I am trying to install a toilet on concrete basement floor. My question is how do you attach the toilet to the floor? On my upstair toilet there are studs coming out of the floor.
Thanks,
Jason

The toilet doesn't directly attach to the floor. It attaches to a toilet flange, which itself is attached to the floor.
This flange is shaped like a wide ring, with various slots and holes around it, and the middle fits into (or sometimes around) the drain pipe. The type of drain pipe you have will determine the flange to use. The flange top will be a little (1/4" about) higher than the floor, and needs to be well supported by the floor *not the pipe*. Ideally, you'd use a brass flange bedded in mortar - rock solid and lasts forever. More commonly plastic flanges join to plastic pipe with solvent-cement. All flanges have slots like long keyholes, which the toilet bolts trap into - the toilet with wax seal is lowered over these bolts and then nuts draw it all together.
In any case the flange needs some kind of non-corroding screws (stainless) securing it to the floor. Masonry drill for lead plug anchors, I guess. Best would be to chip out some concrete and really bed the flange on there as well.

If the pipe is PVC, you need to check the size. If it is 4" pipe you could use a Closet Flange that glues to the inside of the pipe. If it is 3" you should cut around the concrete outside of the pipe and use a flange that glues to the outside of the pipe. If not, you will have problems with blockages later. I always use Tapcon screws to hold down the flange to the concrete. There are holes in the flange provided for these screws. When glueing the flange in place, face the wall that the back of the toilet will be on. Make sure the long slots on the flange are on the right and left side of the hole. These are what the Closet bolts hook into to hold the toilet down onto the wax seal. Some flanges have 2 sets of slots so it's harder to make a mistake but most have only two slots and if you install it out of line, you will have to cut the flange back out. (NOT a fun job). Good luck and reply back with any further questions.
