We are looking at purchasing an older house and wish to add a stall corner shower to the existing bathroom along an exterior wall

Is it it possible to pour an additional slab where we would like the shower stall to be, to allow for the drain, then run the drain through the exterior wall to tie in with the tub drain?

Basically we would have an 8-10" step up to get into the shower, in order to allow the drain pipe to run through the new slab, without busting through the existing slab.

The tub drain ia approximately 8ft away. Note: The tub could also be elevated to equal heighth with new shower and the existing tub drain be run under the new slab, out the exterior wall, then to the shower drain??

We just don't know if it is possible to drain through an exterior all, then tie back in to the existing drain lines.

In this bath, there is also a water heater. We are assuming it was placed in the bathroom to get hot water to the jacuzzi faster, as we can see where it was originally in the garage on the other end of the house.

Is it possible to use the water lines from the water heater, run through the wall, into the attic then back down for the new shower?

We are only thinking about this option as it would seem less expensive than to actually start tearing into the slab. Are we way off base here?

Aside from the bathroom issue, this house is pretty much what we have been looking for, but the bathroom could be the deal breaker.

ANY thoughts and idea on how this could be accomplished would be greatly appreciated. I am obviously a person with little knowledge but much creativity! :eek:

Thank you!

Platforming a shower makes for a unsightly job. Let me give you some options. Click on: Shower Floor Pans
And scroll down to the 60 by 32" shower bases. They are designed for tub to shower conversions you use the same trap and raiser and don't have to break up the slab.
"Is it possible to use the water lines from the water heater, run through the wall, into the attic then back down for the new shower?"
Yes, you may come off the supplies to the "kicker heater" and pipe to your shower valve.
Let me know what you think about the shower base. Regards, Tom

Perhaps I wasn't very clear in my description of what we are trying to accomplish. We want to keep the tub, and ADD a shower in the same bathroom. I asked about making it a step up so the drain could go through and out the exterior wall for tie in, as opposed to drilling the slab.

Sorry for the confusion.
