We would like to add a new bathroom on the second floor of the house. This will be beside the main bath, and will be ensuite for one of the bedrooms.

Is this is possible, how much would be the approximate cost of the project be?

Probably looking at around $10,000 plus tax. This is considering that the structure already exists and very minimal re-structuring required.

Hi. I think a good price would be 7000, materials included.

The cost depends on many variable. It is impossible to say without looking. Depending on on existing plumbing and the structure of the house. Plumbing has to be connected to the new area. When you are dealing with a new area of the house with no existing plumbing or electrical you can expect to pay more. The project could go way above 10 thousand. That is if it is done properly. You need a good licensed plumber. Make sure you do Schlutter or any new technology water proofing for bathroom by contractor. If you go cheap you will have a dangerous scenario. Good luck!

Your costs depends on many different things and with out seeing the project it is impossible to give a price.

There are many details that will effect the price.

Location and distance to existing drain lines, vent lines and of course hot and cold water supply. You have mentioned it will be beside an existing bathroom. But is the shared wall the one with all of the above listed runs in it?

We also need access to electrical. Preferably off a G.F.I breaker on your panel.

We always at a G.F.I. receptacle, but the breaker is additional safety.

Then the fixtures and finishes drastically effect the price. A bathtub ranges from 380.00 to over 3,200.00. A toilet from 148.00 to over 500.00. A faucet, from 42.00 to 210.00, the list goes on and on. Your tile choice, prefab shower base or custom built.

The range will run from about 7,000.00 to over 11,000.00.

I have a client that is adding a steam shower in the basement now, and the construction of the space as well as the unit and plumbing is over 6,000.00 for that alone.

Hope this helps.

Yes everything is possible! The ballpark for such job would cost $10k.

Thank you all for the quick response.

To give you more details, this will be a new house that is being built. We've asked the builder if he can add extra bathroom to the layout they have designed.

Their initial response wasn't very positive and said they will have to check with their architect and get back to us.

But this gives me a good ideal of ball park estimates and possibility of adding one at a later date, if the builder says no.

Thanks again.

It sounds possible as there is existing plumbing on the second floor but absolutely you need it to be looked at. Get any quotes in writing and always read the fine print!!
