There is a drain fitting made for this application. The final connection
is
made from the top. You bolt the main fitting to the shower base and set
the
shower in place. Your vertical drain pipe can be in place, or it can be
measured and glued in place though the top. Then a rubber gasket and
tapered
cone get tapped into place from above, making the final connection. They
are
available at any Home Depot.

Thanks, Dennis. I'll check it out.

In the UK we call them a "top access trap"
