I intend to order a Showerlay Wiper 1000 x 1000 mm Line Pure (plus kit) next Tuesday. I am awaiting the plumber's decision as to the thickness required. If I order the tray by midday on Tuesday, will you be able to get it to me on Wednesday?
I can confirm that this product is available with next day delivery, therefore if you order it on Tuesday before 3 o'clock, we will ship it same day and it will be delivered on Wednesday.
Regarding thicknesses - basically biggest difference between each thickness is the slope - thicker shower tray is steeper. For timber flooring, we recommend 20 mm thick board, as the floor boards usually are 20 mm thick, and by fitting shower tray of the same thickness you can avoid increasing total height of the rest of the floor.
I am happy to assist if you have any questions.
