I’m planning a bathroom renovation, and likely will refactor the layout of the space. One proposal has the toilet moving to a different corner.
We’re all well aware that putting 3" drain pipe through 2x8 joists isn’t supported under any building code, pretty much anywhere.
However, I’m curious if the Ontario building code allows for joist reinforcing products such as this product from metwood, link below.
I’d need to cut a hole for a toilet drain through an already sistered 2x8, and could reinforce the hole with this steel offering. They claim its even stronger than before the hole was cut.
Would that be acceptable under Ontario Building Code?
many thanks for any insights!
