Bathroom vanity tile

The temperature-control knob on my oven slips onto a plastic stem. The stem is broken. Is there a way to fix the stem without replacing the entire, very expensive control module? I tried to glue it, but probably made it worse by gunking up the broken ends of the stem.

[FNT="Fixedsys"]:confused: My boyfriend is tiling a very small bathroom in my house, he's a building designer, and in the process of he has run into a huge problem. We felt by putting down a diamond pattern into the floor we could hide the uneven walls. It didn't turn out as clean as desired cause the lines are way off... Can anyone recommend the best solution to a small bathroom with uneven walls when it comes to tiling? A pattern? size of tile? Any tricks to the trade? I'm willing to learn!!!! ALL ears for suggestions!!!!:alarm: Thanks, Big Time Overwhelmed:wall: [/FONT][/B][/B][/B]
