We have a bathroom in the basement which has a tile shower. The shower started leaking and rotted away the wood around it, so I removed the shower completely (all you see are the studs on the wall and the drain pipe in the ground). It used to be a 36" shower stall, but there is additional space in the bathroom and I want to be able to install a 46" shower. Of course, the obvious problem is that the drain from the 46" shower will not match up to the drain in the ground. This is a 1960s house with a metal drain and concrete surrounding it.

Question 1: Is there any way to put a 46" shower when the drain is centered for a 36" shower?

Question 2: I've heard that I would have to break the concrete and "move the drain" to the new center of the shower. Is this true? And if so, how would I go about doing that with a concrete floor?

Any help is appreciated.

If you don't like the options Tom gives you under question 1, breaking ut the concrete isn't that bad. At least limit how much breaks up by sawing as deeply as you can. The bigger and heavier saw the better, but you may be able to score it enough with a masonry blade in an average 7 1/2'' saw. Break it up, move the drain, and pour new concrete. A bag of Sac-rete or other brand of premixed concrete doesn't go as far as it looks like it should. Buy more than you should need, and take the extra back.
