John here are two closeups. The first picture shows the corners of the grates and the rolled edges. The cover is actually level to the edge. In the second picture you can see the top edge of the trough part of the drain is a finished edge, as you can step on this edge you wouldn't want to cut it down. The gap between the cover and the trough is predetermined in manufacturing. What probably should have been done to make sure it drained even better is for our first row of tile to be set at a slightly steeper angle. Then each row set after that would have continued on the upward slope. It's almost flat to the drain so the water can pool/collect just a little at this edge after the shower is shut off. The entire shower is sloped though so it drains really well while you're using the shower. I just use a squeegee and push the little pooling into the drain. You can see a bit of water marks in the bottom picture, typically I rub a bit of Turtle Wax on the grate covers when I clean them, buff them off, to prevent build up - also spray after each shower with a daily shower cleaner.

seems like it could be a tough one since smell is subjective (although there's probably something out there that can measure smell) plus if more than 1 of u can smell it that'll help. I'm just thinking ahead if u need to file a complain with the licensing board. How long has it been since u texted him? was a good with texts before? i hope he's getting in touch with who he will and then get back to u but would be nice if he let u know he got your msg and will deal with it. I have a very sensitive nose so this problem would be a big one for me. I just got a bunch of air purifiers and have been learning more about pure air. your nose is telling u something. glad u r listening to your body

We just built a shower with almost those exact dimensions, and I want to strongly encourage you to consider a 6" shower curb entry for water control. We, too, wanted to lower the threshold as is so popular with modern showers, but what happened to us and can happen in any situation, is that the floor itself that is to be tiled may need some leveling work before the slope can even be considered. This can quickly eat away at your necessary lippage to keep water out. At least be prepared going into the build that this could be a possibility and that you may need to adjust mid-construction. Even following the proper dimensions for slope, it's a long way for that water to drain, so kicking up the slope a little wouldn't hurt. It doesn't look weird at all. It's totally necessary to get that slope in there so the water won't be sitting over the long surface. Also, at only 80", I think you're going to need some sort of curtain or door to keep water from spraying out the end where your entry is. There are specifications on that somewhere that I've bookmarked, so let me know if you haven't planned a door or curtain into your design, and I'll look it up and link it for you so you can confirm if needed. We used a unique metal coil shower curtain for ours and love it, from Cascade Coil. For our build, we used the Schulter pre-formed shower drain pain and curb forms. The shower drain pain was the longest commercially available, then our tile setters had to build out extra slope to get the full length. If you haven't considered Schluter, please look into it. It's an excellent waterproofing system, and putting this much into a shower renovation, you'll want to be sure it won't ever need to be repaired due to leakage. I believe they have systems to accommodate the linear drains as well. Ours was a re-design of an existing shower into a post-tensioned slab foundation, so we couldn't upgrade to the linear drain but would have if our foundation had allowed for it easily. Also, please look into some version of pre-sealed grout like Mapei. Our tile setters used a standard non-sealed grout, and with that much tile, cleaning is already a problem. We're needing to apply some sort of sealant going forward to help our grout situation. It's a lot of tile to keep clean, but you'll enjoy the space!

You should really re think your plan. Start at the hiring process , get less lost on the internet and uninvolve yourself with drain selections. Make a smart tile hiring decision You want the tile crew that Cites TCNA, ANSI standards , already knows the plumbing requirements locally, and insists and i mean insists on supplying all materials including the drain. Youll not save anything by getting overly involved technically, Make a smart 1 time hiring choice. Did you want any help in that field? how to hire an actual tile pro?
