General Tile Discussion

I am trying to determine proper slope for large curbless shower. (Mudbed and Kerdi membrane on top.) Shower is 43" x 95" with center drain 24" from one end.

With 1/4"/ft slope, the drain is 1.5" down from long end. This leads to a 3/4" slope from the short sides to the drain.

Is the 3/4" slope too steep?

Is it ever good idea for mudbed top edge to not be level all around?

I have a window in the shower, and two niches.

I will be using 5/8 engineered quartz as solid surface shelfs.

Should I lay the tile and install the sill after? or cut the tile for the sill to sit into?

For the shelf, I obviously have to set it into the tile. sides and back.

I am a DIYer working on two new construction showers where the contractors did the framing of the shower and used Glasroc as the substrate. I plan on using hydroban liquid membrane as the primary waterproofing as well as their antifracture membrane in the corners/changes of plane then screeting the walls to get everything square and plumb.

I have some concerns about the layering of hyrdroban (antifracture fabric) > thin set(screeting layer) > hydroban (waterproofing the field) > thin set> tile. I assume its better to have fewer layers of different materials binding to one another. My question is whether I should hydroban the whole shower(for waterproofing the field) before screeting or after.

Lastly, thanks so much for the videos, information and forum to help DIYers get this work accomplished. I really appreciate how Isaac explains the nuance of tile setting and his values around helping people. It’s obvious he…

my knee wall tile ends just below the top. This is based on a full tile just under the window. I have these 3/4 tiles that I could install. but it messes up the top of the kneewall which will have a granit (or equiv) slab. There will be glass block on top of the knee wall all the way to the cieling.

you can see in the window pictures that the tile will stop just above the window. 3/4 tile around the window and a slab at the bottom again. jollybead around the niches.

3rd.. I am trying to figure where I want the black line around the shower walls. I will have white tiles on floor with black design and black sanitary cove. same with the main area.
