Recess shower door & tray query

[BollyR]

I have bought a replacement 1200 shower door & 1200 x 900 tray, ready for a refurb starting soon.

The current door & tray is in a recess, which measures 1200 x 900, but these measurements include the current tiles, which will be replaced. I now see that the new door has a tolerance of 1150-1190 & am concerned it won't be wide enough. I am also concerned the shower tray won't be either, for the tiles to sit on top. I naively thought a 1200 door would be at least 1200 wide, with reduced width tolerances for wonky walls.

I am wondering if it would be easier to look for a door with a minimum 1200 width, rather than packing out walls or sourcing extension profiles, but then what about the tray?

Any input appreciated.

Put a layer of 10mm wedi board on each wall. Will give you the required width and will likely be a better waterproof finish
