I've been installing them for over 20 years. I never mount them on top of the sub floor I've always cut a beveled hole that allows the bottom piece to be flush with the sub-floor so it's not raised. I also do not screw them down. I use and adhesive under them and then build a bridge with 2x4 over it and then screw the drain up until it's tight. Once the adhesive sets up I remove it or allow the tile guy/gal to remove it. This prevents possible tears on the old school rubber membranes by the screws.

Schluter make a great system for shower pan setups.

I don't know if you recall that we are building everything alone. We aren't at the shower yet, but my husband did the rough plumbing, and he had the same issue with the shower drain, leaving more space under. Great video!!!!

Looking good!😊

Definitely would have done foam pan or full fiberglass enclosure. Not worth the hassle of tile and mortar for a cabin 😊

My next project, perfect timing. Thank you for sharing!

I'm so glad to see another video.

The video I watched on building a shower pan on the MR Post Frame | Marshall Remodel channel was useful. It's titled "Self Build Home | Custom Tile Shower Pt 1 | Mad County Build". Around the 14 minute mark He shows using angled strips of 1/2" plywood to achieve the slope.

i speak french too. LOL

That drill saw blade looked really dangerous. Was it really supposed to go on the end of a drill? It does say "internal PVC cutter" but really seems like a solution looking for a problem. There are so many better ways of getting a clean cut of a PVC pipe that doesn't involve harming yourself with an uncontrollable tool. On the pre-slope things, you found the construction version of the 5-pack hot dogs, 6-pack hot dog buns (or whatever mismatched multiples, because it's a globally universal scam).

Theres a brown sand mix from quick crete that would have worked much better it's more of a sand and polymer type of thing
