I am remodeling a bathroom to add a shower and replace the old tub. The existing p-trap for the tub does not line up with the tub drain as is conventionally shown. It is offset about 12 inches. My question is can I connect the new shower pan and the new bathtub to the same (existing) p-trap. The arrangement would be shower pan, and tub tee'ed into the p-trap, then vent, and then drain to the septic tank.
The structure is concrete slab. The water level in the p-trap is about 9 inches below the current slab floor surface so both fixtures would be above the p-trap water level.
