BUILDING NEW SHOWER CURB
Shower curbs are not supposed to be level from inside to outside. The shower curb should be tilted toward the inside of the shower. This allows water to run back into the shower instead of out onto the bathroom floor. A typical curb will be sloped atleast 1/8"- 1/4", which represents about a half a bubble on the level. You can use tile on top of the curb or a solid piece of granite or marble. A solid piece marble, granite or silestone for the top of the curb, half-wall or shower bench, provides better protection against water intrusion.
Frameless shower enclosures are not guaranteed to be leakproof. While you should not have problems around fixed panels, as they are sealed with a high-quality, mildew-resistant silicone, but around actual door (and transom in case if you have steam shower enclosure) they can leak with a direct spray of water.
Frameless shower doors do have small gaps at the hinges and hinge side along the wall, therefore its crucial to have the top of the curb sloped inward, so the dripping water is flowing back into the shower.
Make sure you install the tiles on the outside of the curb in the same manner as the inside. Level and align the tiles, keeping them parallel with the inside tiles. Remember that the outside tiles should be approximately 1/8"- 1/4" (half a bubble) taller than the inside row to give the top "proper pitch".
