My house was built with rough-in plumbing in the basement cement floor as are many houses in the past 25 years. The rough-in plumbing includes a 4" PVC pipe in the floor for a toilet and a 2" PVC pipe for a shower or bathtub.
I am planning to install a walk-in shower with a curb that is 15 inches from the center-line of the toilet per our county code.
The 2" PVC rough-in pipe is at one end of the rectangular shower floor area and protrudes up out of the cement about 2 inches and is capped.
I would like to install a mortar type shower floor base with a drain with a flange. However the flange would be above the concrete floor probably about 3 inches. I have a liner as well to waterproof the base.
Is it possible install the drain with flange without breaking up cement around the 2 inch pipe?
What about the toilet? Possible to install without breaking up the concrete? It would seem the builders installed the pipes so they can be used as-is. I believe all the homes in my area were built with rough-ins similar to ours around year 2005.
