Coverting Tub Drain To Shower on Concrete Slab
We took out a bathtub and want to build a doorless shower in it's place. We have a concrete slab. We are wondering if it is best to move the drain to the center rather than leaving it close to the wall where it was placed for the tub. What parts are necessary to make the change? My DH is thinking of using a skill saw with a concrete blade to cut the concrete. Is there a standard placement required by code for the drain?
He plans to make the concrete floor sloped and do a tile floor. Will this require a membrane or can we skip it? DH is out of work right now so we need to do the work as inexpensively as possible. Any help would be much appreciated.
