Shower tray problem

[Gentleman Jim]

Hi folks - another question.
I'm starting a shower room on Monday and everything seems fine; flat walls, good tiles, nice customer etc. One little thing is that the plumber isn't going to fit the shower tray until after I've tiled AND it is a little too narrow for the tanking tape to reach. My thought is that I just prime and tank from ceiling to floor, tile the same and leave the final sealing to the plumber.
Any comments?
Cheers chaps!
Regards
Jim

if the tray has a flat side to it then no probs it will look ok but most trays have a slight chamfer to the side so will leave a large gap against the tiles..if this is the case get the plumber to get his finger out and fix the tray in-situ.......dave..
