I have an unfinished basement that has radiant in-floor heating. I want to add a bathroom down there and there is a roughed in toilet drain and a sink drain I can hook into. How can I add a shower as well? Is there a shower that can sit above the slab that does not require breaking up the slab. I am reluctant to break up the slab to add drains because of the tubing in the floor.
There are companies like Saniflo and Liberty pumps, that make toilets that are designed for basement or below grade installations that allow for the installation of two other fixtures connected to the toilet pump, or you can get a self contained pump assembly and tie that into the roughed in toilet drain (mainline drain) Look at liberty and zoeller websites.
