I have an inexpensive 'shower stall in a box' type shower in my basement that is set on a 3" concrete base. I need to install a new drain kit but the only ones I can find have around a 5" depth. I'm needing an approximate 2" in depth kit from drain cover to base. I know, it's a ridiculously small area to work with. I'm getting leaking in between the floor of the shower and the concrete base. I only have a little less than 1" of actual drain pipe coming up from the concrete base. I would like to try a Wingtite type drain kit that can be installed completely from the top of the drain but that drain kit is also too deep. Any suggestions on solutions?
