Cost to Built a Toilet in Bathroom

Good evening bargain hunters.

We are looking to buy this house that has only one bathroom and a separate toilet. We really want to have another toilet due to more family members joining us soon.

The existing toilet is to the right side of this bathroom. We want to build another toilet where the cabinet is behind the shower. This bathroom has no bathtub.

How much cost are we potentially looking at for that? Properties with 2 toilets in that location are 100k more and our budget is not that high. Any help is appreciated.

  • You’ll be looking at one day, two handymen and materials. $800 to $1000 plus the toilet.

      If the other toilet is behind it you are probably close but there could be issues with pipe size

      • That’s what core drills are for.

    • Yep. Definitely an entire day job. Your estimate is my best guess too.

    A shovel

    Dig a hole, do it the old fashioned way! It's the retro thing to do

    TOTALLY depends on where the waste from the existing toilet is.

    You'll likely have to connect to that waste.

    If you have to rip up the floor of the existing bathroom, you're looking at $10k. If you can get under the floor and connect that way, $1k.

      yep, the toilet is the cheap part.
      As oscargamer mentions the big cost is in connecting to the waste pipe and plumbing in the water. have you thought about calling a plumber?

      This. As oscargamer said the waste Will inevitably be your main concern and expense. Putting the floor plan would've been more helpful. I'm assuming this bathroom is on concrete slab on the ground floor? Moreover there doesn't seem to be enough space between the basin and shower to meet code but depends on what state you're in. Also what's the reason behind that step up? Are there services running under there already and what kind? If that is a concrete slab then they'll have to dig down quite a lot for the waste considering they may run it under the step to the existing toilet or take it outside the window wall depending what's there.
      Get a few licensed plumbers to look at it and quote. Do not use handymen and strange airtaskers for such a job please.

        Also the space where you're looking to place the toilet is tiny. If those floor tiles are 200x200 then that's a 600x700ish space. Not enough clearance in either direction to meet code unless it's a much larger space. Moreover the feet may be dangling off the step while toilet in use as most standard toilets are 650-700 long unless plumbed hidden into the wall and need specific clearance all around. If those tiles are 250x250 then the space seems around 800x900ish but even then the step down would be a trip hazard. Doesn't seem feasible to get it done to code unless you change the entire layout of that bathroom.

        • That is one of my concerns too. You reckon 25k+ to do the whole bathroom? Pretty confident that it could be sitting on top of concrete.

      • I am in QLD and definitely not using an airtasker or handyman. This seems like a big job by the look of it. I would love to do the entire bathroom with a new toilet but that would probably be a 25k+ job.

    • These are some nice toilet designs :D

    i'd guess that as the shower is elevated then the outlet pipe runs under that step.

    check if council or plumbing approval required

  • Throw the cabinet away and go straight through the wall.
