I noticed a leak under my raised bathroom in the basement. I believe I'm going to have to take a sledge hammer to the concrete raised floor. Is there any way that I could run a new drain without tearing up the cement floor? Too bad they don't make a horizontal or upflush drain for a basement shower, or do they? What would it cost to have my raised bathroom plumbing re-done? I'm talking replacing the main drain, the basement toilet drain, the piping betwen the shower drain and the main drain. All of these pipes would be under the cement. Any idea on how thick this cement would be? Maybe I could eliminate some of the costs if I take the concrete out myself.
