drainage in shower is slow

[Unregistered]

I have a Sulby disabled shower tray and the water drains really slow, the the water builds up while having shower. I have tried drain unlocked and also tried a snake which does bring up hair etc, the shower will drain well for about two days and then the starts to be slow again. Could there be a blockage further down the pipe or could it be the waste pipes are to small.

Any help would be appreciated and
