Adhesive

Not a 'contact' adhesive, so will need holding in place whilst it sets, but StixAll is awesome.

 

As you've raised the shower tray, you may want to keep the UPVC trim removable in the future for maintenance access

In this case, silicon will do the job, nice bead between trim and shower tray, bend into position and use bricks, paint tins, etc, to hold trim in place whilst sili cures

You might want to add a few timber blocks on the floor to help support the trim (again sili between blocks and trim)

Any future waste problems, flexible blade to cut sili and you have access and trim is reusable

Just my suggestion

 

Frame out underneath and use screws with plastic caps so the panel is removable for future access then a bead of silicone on the top edge where it meets the tray

 

Yeah stixall is the dogs danglies shame screwfix dont sell it (hint hint)

 

To get you started, once cut to length(sounds like you've done that already), take it outside(unless you have a bath to use), bend it just past the radius you require(couple of metres of string to tie it there) and pour boiling water all over the inside(back edge).
Let it cool or give it a while and use cold water. Remove the string and it'll stay like that for a long time.
Also consider having something fixed at the wall/s to keeps the ends in. And that way it can pop in and be self-holding even without gluing.
You can then glue with confidence.

Mr. HandyAndy - Really

 

A slight refinement to this method which I have used is to use a hot air gun where the bend is required. I used this on PVC panels in our bathroom for the corners. Didn't need to fit the corner strips supplied and the whole thing looks a lot neater without them. Warning: Practice on a scrap bit first!

 

Hi gordy1 -sorry over the delay getting back - been travelling. Well the PVC panels I had, had a kind of honeycomb backing with a continuous decorative front surface. I had to first slit down the backing honeycomb at the point of the required bend. I then applied the hot air gun to the front surface (kept it moving fairly slowly but on medium heat) and gradually bent the panel at a right angle for both internal and external corners. On cooling, the bend remained. It took a bit of practice to get the timing right and each bend was about 1.7m long. With your project it should be much easier with a small width of PVC and you could get the required angle permanently set before gluing! But - have a good practice first!!
