Hello all,
we've been having an ongoing saga with our loft bathroom. The new stud walls were built out of square by the loft company. The corner walls are more than 90 degrees so when the shower tray is pushed into corner there is a 15mm gap between the tray and the wall on each side by the time you get to the outer edge.
We had the ply walls replaced with hardiebacker and thought the tiler would pack out the walls to make square again but he didn't.
He then cut a slot into the hardiebacker in the corner at floor level in order to slide the tray under the wall by 12mm thus closing the gap between the wall and tray at the outer edges.
Unfortunately this didn't work as the gap he cut just filled with squashed cement and the tray did not butt up under the hardiebacker in the corner.
As a result the tiles would not overlap the shower tray at the outer edges. I used a Mapie shower proofing kit to tank the walls before tiling was done, but the tape peeled off the shower tray at the outer edges because the gap was too big. apparantly it is only designed to cover a gap of 5mm or so.
We also bought a pvc quadrant by Homelux to waterproof the gap but again this is only designed to cover a small gap.
I was thinking about buying the Sealux product as they have a version that will cover a bigger gap but I was advised that this would not guarantee a water proof seal on a 15mm gap.
So I've managed to take up the shower tray and remove all cement with out damaging the tray.
My question is, should we cut into the hardiebacker some more at floor level on both sides of the corner and try to push the tray under some more?
Or is it better to rip the tiles and hardiebacker out and start again and pack the walls out to make square?
