Let me start by saying that I have already read the other threads on this subject... my situation is slightly different because I can't just drill into the floor, much as I'd like to. And yeah maybe with a bit of forethought this situation may have been avoided but it is what it is now....
We had to have builders in to completely renovate the basement because the waterproof tanking appeared to have failed (or was badly fitted by the previous owners more likely). New tanking membrane, (wet) underfloor heating and porcelain tiles fitted and the builders have departed leaving me with the "easy" bits to finish. Which was when I realized that re-fitting the toilet was going to be a problem.
Can't drill holes to fix it down without penetrating the waterproofing. Wall hung toilet won't work either, for various reasons.
Quite a bit of discussion on here about simply using sealant but also at least one comment that suggests it'd "walk" over time and someone else suggesting that if you did too good a job at fixing it down then replacing the pan in the future could be difficult.
I had one alternative idea but I'm not sure how practical it is....
The tiles are 8mm in depth. It "may" be possible to very carefully drill down just 8mm and chemically bond a short bolt into the tile thereby allowing the standard toilet brackets could be used. This could be enough to prevent the lateral movement whilst sealant around the edge (and possibly more sealant underneath) would further lock the toilet into place. The bolts wouldn't be expected to prevent any concerted effort to pull the pan off the ground.
Or is that never going to work?
Is sealant my only realistic option?
Thanks in advance
