Are your Showerlay Wiper shower trays suitable for a Vinyl Floor finish?
Only Showerlay Wiper Invisible are suitable for vinyl floor covering. Other shower trays have vertical frame of 15 mm, so you would need to accomodate that space (best with tile backer boards) to bring it to the frame level, so vinyl sheet is flushed with the drain. If you are able to do this, then you can use any Showerlay, if not, only Showerlays with Invisible drain will be suitable for you.
