Need some Tile advice.

[Alphacowboy]

I need some advice from you experianced tile setters! I do alot of tile work, and regular shower pans, but have my first "curbless" one coming up next week.



Here is the job info... The house only has 2x8 joists, 16" OC, so cutting them even slightly to make a recessed pan is out of the question. I did plan on scabbing on the sides of the joists, and then recessing the plywood floor to be flush with the top of the joists, to gain 3/4". The main floor in the bathroom consists of 3/4" OSB, and will be covered with 1/2" HardiBacker. So, basicly, I will be starting with the main floor in the bathroom 1-1/4" higher than the base of the starting point of the shower. From this point, i am kind of confused as to what to do with the liner and curb area. I know I do need to slightly ramp it up from the outside of the shower and in, and planned on a ~12" wide area, ~1" high, that I would have to hand trowel out.



Kinda of like this...

Is this for wheel chair access?. I've seen a rubber strip that a wheel chair can ride over (it collapses) on Holmes on Holmes. Google handicap access showers there should be plenty of ideas / ways

I don't want you to get upset with me, but the use of OSB floor sheathing for the bath tile floor is a big no no. OSB floor sheathing is prone to moisture absorption. Plywood floor sheathing will preform much better and prevent future floor tile problems.

I agree with the no OSB, but I didn't want to get yelled at either#@$%!

Oh, I agree on the OSB deal, but I am not the Contractor for the construction, just the tile guy Trust me, if it was me, it would be 3/4" T/G plywood. At least he replaced the 1x8 pine lat that was the sub floor! But, I havent had any issues with it when I have used Hardibacker over the top in the past.



I would like to have sloped the entire floor toward the drain, but there is two doors that enter the room, both with existing finished wood floors, and they wanted to keep the new tile floor as close to the same height as possible. I am already most likely a little higher than I wanted. And, now I have another issue... Put down the backer today, (first time actually out on the job with time to really look it over) and if I do a ramped curb around the front of the shower, when you enter the room, its so narrow, that to fit between the shower and vanity, one wheel of a wheel chair would be on the curb, and the other not. Sometimes I really wish some people wouldnt try to be draftsmen, stick to contracting please! So, now I am not quite sure as to what I am going to do.

Alphacowboy do you have a plot plan? Maybe you can hump the floor by the shower. A ramp on both sides to a platform at the shower entrance. May also give you more slope to the shower and a level entrance to the shower.
