We have a renovated basement with no bathroom. We'd like to install a bathroom next to the furnace room, pretty close (3 ft) to the main stack.

What plumbing costs should we expect?

First off you need to determine a layout on floor of what you want and where, assuming you are going to have a tub or shower, toilet and sink then you have three fixtures and many plumbing companies will charge per fixture for the roughin. They will need to break the concrete on your floor and dig down and find the main sewage line and then tie these new lines into that,each fixture will have to be properly vented also.

If the venting becomes complicated then expect to pay more for possible external venting to be run outside the home (this depends on your local plumbing codes what is allowed for venting and the company can advise you of your options) up a wall, you can reasonably expect to pay anywhere from 2000-3000 dollars for this plumbing roughin.

Get a professional plumbing company only, no diy job this and the company will pull a plumbing permit for inspection for you and then the job is properly inspected and you the homeowner are protected.

Sorry for the length of this reply but i thought you should have some details on this roughin.

I am assuming you are trying to make a suite in the basement? I am also going to assume that you are probably a little shy about the city inspectors rolling around your renovation.

As the previous poster mentioned, you do not want to skimp out on a plumber. Anything water related, (plumbing, envelope, roof, etc) it is worth it to pay for quality and trust. My plumbing budget for local plumbing is around 800 per point. So a toilet, sink, and shower, will be 2400. (it may end up being less, but that is what i use for a budget).

Also the previous poster mentioned that the floor may have to come up, and that is extra, and really can only be estimated after someone with experience looks at it. Because if the excavation in question is near existing plumbing, gas lines, footings, etc it may not be as simple as just cut-break-dig.

I will once again stress it is not worth it to go cheap on plumbing.

Good luck with your reno.

Hello Marie,

The above ground 3 piece basement bathroom system you wish to install is called a Macerating Toilet System. How this system works is human waste, along with toilet paper, is liquefied through means of a rotating cutting blade. When mixed with flushing water the waste is pumped out through a 3/4" or 1" waste line from your macerating system to your main stack as a fine slurry.

You can buy one of these Macerating systems at your local Hardware stores. They go for about $1,000.00. For the installation of this system I highly recommend you hire a licensed plumber. I'm sure you have a friend who knows one.

Good luck
