Thank you all who responded to my earlier question regarding radiant floor heating. Here’s one for any of you tile gurus. I have repoured the basement floor in our house, concrete placed on top of two inch rigid insulation, with Pex piping throughout. I left open the approx. 3 foot by 5 foot shower area. My intention is to tile the bathroom floor and shower, with no step between the floor and shower, so that the shower drain will also act as a floor drain if necessary. I got the idea from a shower I saw in a motel that was wheelchair accessible. I left the shower area as my last pour, with the intent of finishing the concrete so that it slopes from all four corners toward the drain, the subsequent tile to be continuous from the flat bathroom floor, then break downward at the edge of the shower opening, to the drain. I originally was going to just have the shower base begin level with the edge of the existing concrete, at the shower opening, and slope it on down from there, but I got to wondering if I should hold the concrete down a bit from the existing edge, possibly a quarter inch or so, then sloping it down. Any suggestions? I want to make the tiling job as simple as possible. I do have a little wiggle room in adjusting the elevation of the drain, but not much.
Thanks, Norsky
