Questions & Answers

I have a friend from school who is a contractor and is very knowledgeable with tile work and after picking his brain for months, watching tile coach videos (recommended by my buddy) for months I finally got enough courage to demo our shower and start the process. I'm a DIY'er, an aircraft mechanic by trade, so I enjoy learning and doing things myself. I take pride in my work and have trust issues with shade tree "professionals" doing work for me. I'd like to just get some insight from some of the pros on here on my build strategy.

The basics:

Oddly shaped shower for a beginner, first floor slab shower, previously fully tiled, I have a builtwithfoam custom Neo angle pan, putting in a schluter curb with that (forgot to order the builtwithfoam curb), FloFX drain, Durock walls with hydroban waterproofing brush on membrane. 12x24 porcelain walls with 2x2 porcelain mosaic floor.

Work completed:

demo'd, busted the concrete out around the drain and cut it out, installed coupler and filled with pea gravel then re cemented. Removed door frame to widen and raise (built temp frame to support because it was a header), installed new header and frame. Raised/installed moisture drywall ceiling to 9ft (to upstairs floor joist), installed a few halo lights in that. Removed shower valve and sweated in new valve while raising shower head (pressure tested valve and shower head), leveled the floor with levelquik, shimmed my studs using shims/sister studding and installed most Durock except for lower level which I'll finish after the pan install this week. I didn't want to step all over/ladder use on the pan as much as possible while cement boarding so I did most of it first even tho maybe a little out of typical order. I also didn't want to use Durock but was advised to do that's what I went with. I feel backer board would have been easier to deal with but it's working out pretty good.

Questions:

1. Waterproofing my corners in the foam pan? I bought laticrete inside and outside corners and planned on installing those possibly with laticrete bans as added corner waterproofing on floor and curb then painting hydroban over everythint. My friend says just tape/thinset all corners except curb (use prefab corners) then paint waterproofing. The built with foam pan doesn't have any waterproofing on it, straight white foam. I wanted to do membrane but the size is too big for the nominal membrane size, you would need to use 2 pieces creating a seam. Spoke to laticrete tech support and they advised to just use waterproofing.

2. Please advise if there is something I need to consider or do differently in my plans. The pan is going in this week. This is a slow project because of work, kids and life but that's ok with me, we have other showers, my main concern is doing it right the first time.
