shower install questions - finishing basement
bought a house 1 yr ago and am working toward finishing the basement. The plumbing for a bathroom is already roughed in, and most of the basement was already framed by the previous owners (including the bathroom). The width of the bathroom is only 56" so I'm looking at installing a 48" stall/kit. Right away I am running into an issue with the rough-in drain location and the fact that all of the shower kits I'm finding having drains located in the center of the basin. Aside from busting up the concrete to relocate, what are my options? One thought would be to frame in a riser to elevate the base of the shower; giving me room to run the drain line to the center of the basin. Is there any code violations with doing this? Does anyone know of a 48" shower kit that has a drain on the left side? Most kits I see with left-side drains are minimum 60" wide.
here's a photo for reference.

Try E L Mustee. If they don't have it, I don't know who would.

Its not uncommon to have to make cuts in the concrete for drain related issues. The cuts will reside completely under the new shower base and not be an issue during the build. Cut back to accommodate your base, rough in the drain and trap, block off the new square of dirt like you have now, and fill a couple of off the shelf bags of Quickrete to fill the old hole.

Hello... Let me ask you the million dollar question? What size drain is in that pit??
It looks like it was roughed for a tub and not a shower... You cannot put a shower there is so...
( Unless you replace the line back to the branch/main....)

Lawrosa, I have posted phone #s many times to that company & others for members to get information. They were never removed. Did the policy change in 2014?

Pulpo - thanks, i'll check them out.
Czizzi - thanks for the input, I'll keep this option in mind as the more I think about it, its well within my skill set to tackle.
Lawrosa - Great question. I'll measure when I get home, but from what I remember, it looked like 2". However, even if its 1.5", why do shower's require 2" and tubs require 1.5"? If anything, I would think you would want 2" on a tub due to draining large volumes of water at one time; not the other way around. Not to mention the fact that if tubs generally are 1.5", and 95% of bath tubs these days are a tub/shower setup that are used mostly for showering purposes, wouldn't all those people be having issues? What kind of troubles would I face if using 1.5" on a shower (aside from a code violation)?
I don't mean to come off like a know-it-all...I just need help seeing the logic here.

A tub has a large apron and holds water... It flows a rate consistent to that.. A shower has a small apron and the pan does not hold a lot of water. A larger pipe is needed to drain faster so overflow does not occur..
Additionally a tub has an overflow.....
Hope this makes sense....

Checked last night - it's 2". Didn't need to measure....written right on the pipe.
So, my search continues for a left-hand drain 48" shower insert/kit. Option 2 will be to demo the floor to make room for plumbing to a center drain.

Yes I think I'll go that route. Only options I can find with left-hand drain are well over $1,000. I like sterling too; I think I'll use the identical unit that we put in my mother's place this past summer. Got it at Lowes for a pretty good price, installation could not have been much easier, and the finished product was pretty darn nice for a shower-in-a-box.
