Hi,
I am in the middle of a 1/2 bath remodel which consists of replacing a fiberglass shower surround with backer and tile and a mud pan. After demoing the old surround, I found that the original construction method was to leave a 12" x 15" opening in the poured slab for the P-trap and drain riser (see the attached pic).
Since I'm going to be installing a mud pan, should I just encase everything in the hole in concrete before I start? Should I fill gravel in the hole up to the bottom of the existing slab, or does it even matter....should I replace the old trap while I have the opportunity? The house is almost 40 years old and in San Diego (no frost etc).
Thanks for any advice!
