Installing a new shower in a concrete floor, high-rise
I just purchased a condo in a high-rise and am hoping to make some master bathroom/closet renovations. The condo layout is such that there is one large bathroom with a full shower/sink/toilet directly parallel to the master bedroom walk in closet which only has a small bathroom with a sink and toilet. My question is... Is it necessary to drill new drain holes in order to put in a second shower in the master closet or can I plum the drain to link to the next door shower drain? This would make things much much easier... If not, generally home much does installing a new drain in a high-rise condo with concrete floors generally run... ballpark? Thanks
New drain - New Location in concrete high rise construction
Moving drain lines in a condo is a very tricky thing to do. Getting permission to work from below and paying for all the changes and repairs can be costly. On one project my client offered up new painting to the entire bathroom after we dropped their ceiling. This is the only time I have been given permission to do so.
Moving showers is easier since you can leave the drain location and just make the shower where you want it. Quick Drain USA makes a side outlet linear drain that is fully cUPC approved for use in residential and commercial renovations. The drain sits about 2 1/8" off of grade and outlets out the back. Using a drain like this you can position the drain in a new location or even the next room if venting and drain lines allow for this.
Using a wall hung toilet can help you achieve new locations for toilets and if planned right the exposed plumbing can be a seat in the next room or in the bottom of a dresser.
Trying to move the pipe is a real challenge. It never hurts to ask but planning the space with the existing drain lines is always a safer bet.

If your neighbor is moving out and they have dropped ceilings in the area where you are moving pipes then it might be worth asking. They are doing you a favour by letting you do this. Maybe offer up a round of golf or spa day.
They might surprise you and say no problem - go for it.
You might also tell them you will use a premium sound proofing material. If you use Noble Company's Sound Reducing membrane under your tile they won't hear you upstairs.
Anytime you drop a stack you run the risk of falling debris clogging the line. Make sure your plumber plugs the drain line with something before he snap cuts the pipe.
Remember that you need to slip on a no-hub fitting so you will need t o factor that in to the shower floors calculations...
The drain only come in one size. I was able to make this shower larger by customizing the shower pan.
I installed the drain and ordered a larger strainer (tile insert) and used some custom 316 Stainless and Mapei's 315 to fill the open exposed membrane after the marble was installed.
You can see a finished picture of the steam shower here;
I used bags of setting materials to hold back the water. I later sett this flap done over the tub deck.
Leak Test - Flood Test (New shower drain in concrete high rise build)
Make sure any work you do in the high rise meets building codes. In Florida you are required to flood test the new shower for a minimum of 15 minutes but 24-72 hours is much better.
This shower we flood tested for I think three days.
The process is easy with an inflatable test plug and extension hose for the plug.
A 2" inflatable test plug works best.
This needs to slide in to test the connection of the drain to the plumbing line.
Fill with water and mark. Call for inspection. I printed of the IAPMO reports for the drain, the Noble Seal TS and the Aqua Defence used in this build.
Inspector left this for me....
