Unexpected Cost #2: This wasn’t going to work anymore, as the roof at the back is flat, and did not have an attic space. The solution was to run the trunk lines inside the walls between the toilet and 3rd closet where the attic starts. The changes this resulted in was not only revised drawings, but now getting a very expensive wall hung toilet. This means the toilet tank is hidden within the walls which saves about 6” of space in the washroom. The alternative was a standard toilet, but take away space from the closet which was an unacceptable solution. For added energy efficiency, we have an HRV to reduce on the cooling bills in the summer.
We were now ready to proceed, the following are some photos from this install.
