I don't know, but perhaps that the idea is for foods to cook more evenly, instead of having the edges overcooking while the middle is still "sad" (underbaked). Or maybe the idea is to compensate for baked goods that rise in the middle... think of a cake baked in a flat pan- it's taller in the middle and shorter along the edges. I've seen recipes for layer cakes that call for the baker to use a knife to slice off the "dome" in the middle of the cake so that all the layers of the cake will stack evenly. It would be interesting to bake a single-layer cake in the pan and see if the cake is more uniform in height than cakes baked in a flat cake pan... Good luck, Virginia

I'm pretty sure I know what you're talking about, and I have seen this happen before. Do you have a screw smack dab in the center of the drain cover? Without seeing pictures, and without seeing behind the tub, I'm going to "guess" and say it's a Gerber waste and over flow. I'm also going to assume you have to lift a lever in order to stop up the water in the tub correct? You can either change out the trip lever for a blank cover plate, and the drain can be changed out to a "lift and turn" style drain. All of this can be done from the front of the tub. If you know the manufacture of the waste and over flow, you can contact them to see if they have different strainer style. If you have access behind the tub and it's Brass...it's most likely a Gerber. But Gerber also make a plastic waste and over flow as well. However, if it's plastic, it could be a number of manufactures. If it were me, I would replace the trip lever with a blank face plate, and install a lift and turn. Since the lift and turn's seem to gather hair much quicker, you can leave it out until you use it for tub applications, and purchase a $2.00 screen from your hardware store to collect the hair. The hack way of doing things would be....concave the strainer yourself by pushing it in. It's very easy to do. : )

"Here I am thinking of safety etc. and he never thinks anything bad can happen" Oh Piper101, I deal with this at least once a day in my home. Didn't think anyone else had this little 'problem'. Yes, different how they think, huh? lol MsRose, Personally, I love the big mirror look in bathrooms. Maybe because I've only ever had very small bathrooms with just enough room for the itty-bitty medicine cabinets with mirror doors. Would love your mirror! If it were my mirror and I had removed it by just whacking it (using all the safety procautions possible) and it came off in pieces, I'd repair the drywall (Very simple repair since it would only be a section of wall, not a whole room) and add the nice, decorative mirrors I've been seeing all over the TV and magazines. One sink, one larger mirror. Two sinks, each would get a separate mirror. Both would be nice enough that they would practically be focal points for the bathrm. I would get that done ASAP so that I could get to the creative (read: FUN!) part I love to do and that would be to use the broken mirror pieces to create something ala mosaic. Sooo many mirrored decor pieces out now on more upscale websites I've seen and the prices could choke a horse! From mirrored night tables to lamps. So, if you are asking what to do with the mirror should it not come off in decent pieces, I'd keep the pieces and create something fab-ooo, something unique, something special for my home. Here's an idea I found on the web not too long ago (while looking for ideas to use my Bordello Bunny pieces and shatters that were once two trays).

I have one and I love it because of how they reflect and scatter the light. Right now it's up in the attic waiting for a place to go, but over the old house it was over the piano....now that I'm thinking about it, that's where it should go here too as the piano is on an inside wall and it would reflect the light from the opposite windowed wall....perfect! Thanks for reminding me!! And I'd really hate to see it painted in bright colors....they are what they are and I like them that way....
