My son and his wife moved into a house with a second floor laundry room.

To prevent washing machine overflow from pouring onto the first floor
ceiling below, the washing machine sits in a large plastic tray which has a
raised lip around the perimeter and a floor drain connected to the bottom
which empties into a drain / waste PVC connection. The washing machine
laundry tray looks like this:

The front edge / lip of the tray has been broken, leaving no protection
against water overflow.

The obvious solution is to buy a new tray, temporarily remove the washer,
install and plumb the new tray, and then (with two muscular people) lift and
set the new washer down onto the new tray. This is a few hundred bucks using
local contractor parts and labor.

One cheaper alternative is to find a way to reconstruct the broken front lip
of the tray. Since the rest of the tray and all the drain plumbing is
intact, this seems to be a much more attractive option.

Any ideas as to how to accomplish this?

Many thanks,
