Newbie to the forum here

Im installing a curbless shower entry for our bathroom. As per the instructions i have the recessed subfloor done. However there is a 1/2" difference to the bathroom (outside the shower) floor.

I have a few questions.

1) Should I raise the level to flush by putting 1/2 ply over recessed subfloor? or
2) Is a 1/2" recess for shower area ok?
2a) if the recess is ok? how do i waterproof the lip?

If I do raise it, how do i put the 1/2 ply over?
1) Glue it?
2) Mortar?
3) Screw ply to thw sub floor every 12"?

Now for a wedi ligno pan question. I nees to bring it down to 32" from 36".
1) Can i cut the Wedi board 1" on one side and 3" on the other?

Hi Vignesh, :)

Use 1/2 in. plywood to raise the floor drive screws 8 in. apart in both directions into the layer below. Try to avoid the joists.

I have never installed a Wedi floor and will let someone else answer that question. :)

Hi Vignesh,

Add 1/2 in. plywood. Drive screws 8 in. apart in both directions. Try to avoid the joists and screw only into the layer below.

I have never installed a Wedi floor. :)

Re cutting wedi down, don't exceed 6 inches on either side as more weakens the board structure.

You'll be fine.

I think what you are saying is that the subfloor is only recessed 1/2 inch? I don't understand why that would be. Is your subfloor 5/8 inch thick plywood or 3/4 inch thick OSB?
