In response to Re: From tub/shower unit to shower unit
: We would like to replace existing one piece fiberglass tub/shower unit with multiple piece shower unit. Drain in existing unit is on right hand side where shower unit drain is in middle. The plumbing is in concrete slab. Is it OK to connect shower drain to existing tub drain as long as we have the correct slope even though the drain will be 26 inches from the p-trap drain? We may have to chip out some concrete to accomidate the elbow joint under the shower drain.

The p-trap needs to be directly under the drain. Also, tubs only require 1-1/2" drainage lines, a shower requires 2" drainage lines. You are absolutely going to have to take concrete up. How hard it is from there depends on what you have under the concrete.
