Abstract: An integrated shower base designed for improving the drainage of a tile shower is disclosed. The shower pan may be custom fabricated and molded with a depression surrounding a drainage opening for receiving a one piece floor drain. The pan and floor drain are welded together to prevent leaking. The floor drain contains weep holes so that water that seeps through the mortar on the shower floor and into the shower pan can drain properly without leaking. The floor drain also contains a reservoir for holding water that drains through the regular shower drain and also for water that seeps through the shower floor. A mortar guard is placed over the weep holes to prevent the holes from becoming clogged. A drainage mat is placed over the shower pan to help water seepage flow to the floor drain.
