fitting shower tray few questions please

[happyhero]

Hi I am fitting a shower tray and would like some advice please.

Firstly I have read that I should bed it on some mortar or silicon, silicon seems a good choice for me as I think it will be easier just to smear a layer over the whole base as I read somewhere. The bathroom has floorboards and for looks I want to keep the shower tray as low as possible so I don't really want to put ply underneath or similar, will it be ok on the floorboards with this silicon bed?

How thick should the silicon bed be?

Also it has no upstand so is there anything special I should do to prevent future problems, ie add anything or, or fit in a certain way?

If I had an upstand I understand that I should have channeled the wall a little to get the upstand level with the wall ready for tiling, so as there is no upstand do I still channel to rebate the shower a little so that the tiles overhang a bigger chunk of the tray or is this pointless now?

ie shall I just push it up against the corner?

Any help appreciated.

Could someone move this to the tiling forum for me please, thinking about it, I think that forum might be more appropriate.

Hi seco services, the house is 1930's and they are the original floorboards, which are about 6inches wides and I think probably about 18/19mm thick but have not actually measured them for thickness.

What do you think?

Or can anyone tell me how to do the mortar bed, ie what mix and how thick?

Any help would be appreciated.
