I've removed the old tub and want to build a shower pan on the slab foundation. I want to connect the new shower drain to the existing tub drain. The old drain is 1.5 inches and the p-trap is below ground level (there's a square cut out of the slab at the drain location). My question is since old drain is 1.5 inches and showers use 2.0 inch pipe, how can I do this without excavating the earth all along the pipe to reach a 2.0 line? I know reducing 2.0 to 1.5 is not a good idea but I'm at a loss now for ideas. thanks!
