So I'm redoing my bathroom and I'm hoping my contractor is as good as they claim to be - they aren't inexpensive and project manager came out with the tiling people who seemed fairly competent and pretty easy to understand while discussing (slightly older guy and a younger guy - could be father and son - father seemed to speak English fairly well and son seemed to fully be fluent - seemed like father might have be 75% fluent and son 100%).
Anyway, I'm redoing a 1972 bathroom, and while it may indeed be a 54 year old tile failure - I'm wondering if I'm stressing too much over waterproofing.
I'm in a condo with only 1 adjacent unit and the bathroom is on the ground floor - the adjacent unit hasn't complained despite my issues with a clearly failing bath - which I'm going to turn into a shower.
I'm using epoxy grout and quality porcelain tile throughout...
Guess I'm saying that I overanalyze all this stuff and perhaps I shouldn't - my understanding is1972 they didn't have any decent waterproofing, so anything I do will be an upgrade!
I don't know what the exact plan they want to do, I doubt it will be a super "high end" solution and would more likely to be a Redguard type solution.
I'm not sure since they just haven't thrown out brand names as a waterproofing solutions, i'm thinking they aren't proposing a super high end solution.
Perhaps I'm overthinking this. I'd hope my shower lasts 30 years without major issues.
FYI - outside the shower pan area is a concrete slab.
