Shower Screens/Doors?
Remember when ordering any shower door and/or shower screen, measure the opening after the walls have been tiled and allow for seal depth and hinge depth. OR choose "Tight Size" on the "Made to Measure Shower Screens" ordering page.
Once the glass has been processed and toughened it cannot be cut or trimmed down more than a couple of mm at most on the edge polishing machines.
This would be an expensive mistake as we cannot except any responsibility for errors of this kind on your part.
