Drain for new kitchen in old bedroom on slab

[frankieb]

Old bedroom on slab floor. This room is next to a full bathroom. Wife wants to turn this bedroom into a kitchen. The original kitchen is upstairs and not sitting over this bedroom. What I figure is I need a plumber to come out and find if there is a drainpipe anywhere under this slab. Also wondering if they can hook one up to the bathroom which is the next room. Closest wall is the shower. Basically a plumber has to decide is there is a drain pipe anywhere usable. I have no idea on cost of finding this out. Also cost if possible to attach to the bathroom if thats the best way to go. I already know its a big job since its on a slab. Any ideas? Wife is set on this old bedroom turning into her new kitchen. Electrical and vents not so much a problem. Its the drain line for the water from the sink that has to go somewhere. Hot and cold can come from the shower through the wall. help???

That’s something that has to be seen in person and you would want a plumbing contractor that specializes/deals with slabs they are a different animal electrical water drains and heat are in the slab I dealt with a leak in the floor of the kitchen there was no rhyme or reason to the way any of the piping was done ....get someone experienced in slabs

what I as a plumber would do at your house
look at the floor plan
look at where the location of the sewer exit is at
then formulate in my head, Using years of experience the route the old plumbing
For additional information. I would pull a terlet and using a sensitive device determine the direction the terlet is draining in relation to the house.
then I would ask you where you want the new plumbing.
I now have the information i need to determine where to cut the slab and rough in your new kitchen.
I would then give you a price. If you agree. we would sign a contract

If I was wrong in my estimate then the extra cost would be on me
this is where experience comes into play.

Yes that sounds like the plan. I will contact a professional soon. Soon as I find one that knows what they are doing. I know the first part is to find out if its even possible to put a drain in the room. I thought they might be able to connect it to the shower drain thats just beyond the adjoining wall. Wont know anything until someone looks at it I guess. The wife wants it so I am stuck on having it done. Cant believe how fast both your replies were. I need to come here all the time.

Don’t know the age of your slab the ones I have worked on are from the 50s they were supposed to be for affordable housing for returning war vets

A plumber could run a snake with a camera and a sonde signal sender down the drains from upstairs, and down the drains in the bathroom next door.

This would give drain routes and locations and good guess at drain pipe sizes.

There is probably no good reason for existing drain lines to be found under a bedroom on slab, unless you luck out and the bedroom happens to be the best route to get from here to there when the house was built.

You might end up with the bedroom floor all tunneled up and looking like an ant farm when you are done, as long as your wife can tolerate lots of demo and maybe even some backhoe work outside.
