Can I build a corner shower pan out of concrete?

Yes, a corner shower pan can be built out of concrete, although they are not the most visually appealing type shower pan. When creating your concrete corner shower pan, make sure that it slants towards the drain. You do not want to feel like you are showering on a hill, but a slight decline in the direction of the drain ensures that you are not left with standing water. Also, rather than using water to mix the cement, use a strength enhancing latex additive due to the thinness of the base. Finally, make sure you test the shower pan for leakages by plugging the drain and filling the shower base and checking to see if the water level drops.
