How to pitch L-shaped half-wall for shower?

I have an L shaped half-wall to form the end of my shower enclosure. I want to pitch the top plate of the wall to the inside of the shower to allow water to run off. However, the wall has a short return L at one end. I want to put a piece of granite on this wall but I'm not sure how to pitch the L. A 2% grade would be over a quarter inch in 14 in which might be obvious. I assume that the channel for the shower glass can absorb a certain amount of pitch but not sure how much. I don't really want to miter the granite and bevel it at the 90 corner but would rather have it in one piece.

Ron is correct, slope the granite not the top plate of the wall. This way the glass rail will sit properly and the packing will work as it should. If I understand you correctly the granite makes an "L" shower side. Probably the best way to do that is to cut the granite at a 45 and slope both pieces toward the shower.:) It doesn't require much slope in this case and 1/4" may be too much.:)

Thanks

The granite will sit on the L and overlap both sides of the wall. The shower glass will sit on the granite. The L shape is what complicates things, for me at least, since it requires either cutting the granite at a 45 to get it to slope inwards on both legs, or running a long pitch down the L leg. I was just wondering if there was a usual and customary way to do it. Sounds easier to take care of it with thinset than planing the top plate regardless of how I cut it.
Thanks for the responses!

I think you may be right. It will be wet regardless but I would like to have a little runoff so I don't have stagnant pools growing mold along the glass seal. Someone suggested a squeegee blade after every shower, but that's not me and I don't have a maid so I thought I would put gravity to work for me.

I understand your concerns but I'm thinking a little water standing isn't a big deal. The water will evaporate and of course that evaporation is what causes water spots but if you don't care to use a squeegee or towel dry surfaces after every shower-use, then what?

Ventilation and air flow is as important as anything else. If you create some air flow and allow it to operate for a time after each shower use, it will go a long way in deterring mold and mildew growth and it is a hands-free method.

As far as "stagnant pools" I'm not seeing that happening if all is built correctly.:)

Thanks Bud.
"Stagnant pools" was a bit of an overstatement to be sure. I think I have reached a point where I may have been obsessing on too many details and forgetting the big picture. I put the top plate on flat and will pitch the granite a little and let the water fall where it may.
