shower stall replacement

[ed4344]

I am replacing a shower stall that was installed over 30 years ago. The
problem i am having is disconnecting the drain. The drain connection is not treaded it has a rubber caket between the floor and the pcv pipe. I can only see the connection from the top (looking down the drain). I cut
the floor base out, except for the drain and soundrounding areas (about a foot).

While there are some variations primarily shower stall drains are one of two styles.

When it is accessible from underneath they often use a drain basket assembly that has a rubber gasket and locknut on the underside of the shower pan.

In a situation where the underside will not be accessble we use a shower drain assembly that will slip over the end of a PVC pipe and be glued in place. The finished drain basket is screwed down from the top to lock it all in place in the same manner as a Tub Drain.
