Our 10 year old house had an option to add a 2nd floor bathroom. The space in the floor plan is there in the house ready to go.

I think the getting the water sources up the the 2nd floor is no problem. The new bathroom is right above the first floor bath.

Question, how would I set up drains for sink, tub and toilet. Is this even possible.

Thanks

 

Anything is possible, especially if you are willing to throw enough money at it. But your situatio all depends on your house. Was the upstairs bathroom roughed in for the bath? If not piping will have to be run to connect to the drain lines below the first floor.

 

No plumbing roughed in. Also, there is no below the first floor, as the first floor is post tension slab concrete.

 

The pretty stuff in the new bathroom is probably what's on your mind but I'm betting the details of running the piping for the new bath will be a big driver of the cost. The drain piping is somewhere below your existing bathroom. Drain lines from a new bathroom upstairs will somehow have to tie-in. At the minimum a wall on the main/1st floor will have to be opened up to run the drain pipe. Then a connection to the existing drain piping in or below the first floor will have to be made. It can be done but how expensive will depend on where everything is located.

 

Plumbers and contractors will be more familiar with what is hidden behind the walls and under the floor so best to start with asking for estimates. You basically know what you want upstairs and they can provide some of the details for making all of the connections. This can be a DIY project but due to the time (other areas torn apart) and complexity you might just go with a good bid.

Check local codes to see what permits are required and who is allowed to do the plumbing and electrical. Requirements vary with location.
