That's the plan. I mentioned the "gap" but I guess I didn't elaborate that it would get filled with silicone. When I started the discussion I didn't plan for filling in all the little details about what I was building...I was just asking a question verifying that thinset would work and that the dude who said it wouldn't was wrong. But lots of curious people on here! Which is good because the forum would be boring without all the discussion. I appreciate everyone who contributes their thoughts and ideas.


By the way, I'm using Laticrete 317 since I'm also using the kerdi membrane. When I tile and move beyond the kerdi to the rest of the walls in the bathroom then I'll switch to a modified thinset. The 317 will only be used in the shower area wherever there is kerdi.

The wedi would work fine like that.

What would you use?

A 1" x 1/2" deep trough is a lot of silicone. I figure one bead would work, especially since it's on a vertical surface. Was this air gap the part you thought you damaged so now want to do a flood test?

dax, part of my asking questions is to find out what your plan is and I'll admit I'm struggling to figure it out. If you did a liner, there's no reason for 'kerdi' on the top of your curb. Just one of many examples.

Seeing as you've been doing this shower for weeks, I assume it's your personal shower?

I'm sorry you're struggling to understand. You've made some incorrect assumptions but hopefully you'll forgive me if I don't address all your questions. I'd have to lay everything out and I don't want to write that much.

Nothing. I'd have to think of some scenario where I'd do something like that and off the top of my head, can't come up with one. Maybe a sick relative, but if that's the case I'd just have them demo it, I'd give them a new one and expense it.
Sometimes people put tile on tile, but not a fan of that either. Or tile on vinyl. Know that people put tile right on plywood and seems to work for them. Sometimes just strange things out there but doesn't mean I'll partake.

The seat gets put into the corner with thinset on the verticals on the back sides of the seat. Since the floor slopes at a 1/4" per foot the front bottom of the seat would have a gap due to the floor dropping off. So you set it in some thinset and trowel it off flush so nothing sticks out past the base of the seat. All it does is provide some support to the bottom of the seat much like if you set a tub in a mud bed.

Your floor tile goes up to the bottom base of the seat. Then you tile the vertical on the seat and it will cover the joint where the floor tile butts up to the seat. Then tile the top of the seat, covering the vertical edges of the tile on the verticals.

Does that help?

The alternative to setting the seat in mud is to grind the bottom to match the angle of the shower floor. But the seat looks to have a waterproofing that I don't want to disturb.

Yes, I know the top of the seat will need to slope into the shower for water drainage.
I like where my bench meets the shower floor to be straight. On a 4' bench there would be a pretty good slope at the bottom of the bench is that right?

Do you account for the bench when you center your drain?

Thanks

Mike

Hi Mike,

I would call mine a corner seat rather than a bench.

The drain position in relation to the seat was considered. The shower is 62 inches long. The seat is 16 inches.
