Several years ago we redid our bathroom. We have a large shower/tub room with a freestanding tub. I made the mistake of not having an overflow drain put in, and where I live one is not required by code. The contractor we used did a wonderful job of putting a sloped floor in, which runs to an 8' linear drain. One night we deliberately overfilled the tub to see if the slope was enough for an overflowing tub. That is when we realized that the hole in the tile floor that the plumber used to set the tub drain is way bigger that the circumference of the pipe and a lot of water just went under the tub and through the hole to the floor below. We can buy an overflow valve attachment for the tub, but we would have to go through the tile floor, which wouldn't be a problem except that we have heated floors and it was installed on one circuit, so to speak. If the heating element is damaged when we put in the overflow attachment, then we lose the heated floor in the whole bathroom. The hole in the tile through which the tub drain runs is about 4x4 inches. How to best address this? I was thinking pull the tub up/off the waste pipe (tub is not porcelain, so not too heavy) and put some kind of flat flange, sealed onto the floor and onto the pipe? I was thinking that or take tub up, replace the tile the pipe comes through (no heating element under that particular tile) and drill a hole just big enough to get the pipe through, then seal the tile to pipe. Thoughts?

either way would work. what i feel is important is the pipe sticking thru the floor. is it a chrome pipe that slides into a fitting below the floor that tightens with a plastic nut?
i would take replace it with the thickest wall pipe available. sometimes those pipes are supplied with the tub drain and are thin and flimsey. only take a couple of minutes to do.
seal the hole between the tile and the pipe with 100% silicone caulk, not just grout..
