I would put a masonry blade on a circular saw and cut through the slab first. This keeps a defined area to break up the concrete. Once you get the area open to where you tie into the main sewage line, you'll need to go down probably close to a foot.
When I am installing a shower on the ground or below ground level, I like to include a 1 way valve in the line so water can't back up into the shower. Just a safety feature that you'll appreciate if the drain gets slow or there is a problem with the sewage lines. ----- Original Message ----- From: Shane Hecker To: [email protected] Sent: Thursday, July 09, 2009 10:40 PM Subject: [BlindHandyMan] plumbing question I've got a bathroom which has a sink and toilet. We're ading a shower and tub unit. What are the steps to install the drainage? The building is on a concrete slab, so I know concrete wil need to be broken up. How deep in the concrete does the p-trap need to be? Shane [Non-text portions of this message have been removed]
