Shower tray recommendations

So, I'm a little confused. Ben Gee. I do have to raise the tray, so I was originally going to place some OSB3 on top of some new 4" X 2" joists. I was then going to sit the tray on a bed of mortar on top of the OSB3. However, I thought that the legs would be much easier, especially with such a heavy tray, in a very confined space. But then started thinking on a 1200 X 800 tray, how do yo get to the rear legs to adjust them accurately? The last time a set up a pulley, fastened to the joists above to carefully drop the tray in under control

The standard kitchen legs are rubbish stick with your method

Put a level on the floor and shim it up level. If it’s say 3mm out left to right, then have the left leg 3mm longer than the right.
I set the four corners and purposely have the intermediate legs a fraction too short so they don’t interfere levelling it by the corners. Then wind the intermediate legs down to touch the floor.
The legs can be adjusted by sticking a long slotted screwdriver Into the ribs and turning them around. Bear in mind if you have done accurate initial measuring they adjustment needed will be zero or very little.
If necesssary I use timber blocks and windbags to take the weight of the tray off the legs to make adjustments easier.
Even if you don’t use this method you have to get yourself at least a pair of hedgehog air wedges - they are so useful for many tasks!
