Self contained shower cubicle - how to lift into place

[LianneB1]

I have a self contained shower cubicle, which is very heavy once constructed - it has to be constructed away from the wall with enough room to walk round for fixing together. My question is, does anyone have any good ideas how to manoeuvre this into position once it is built?

The tray is made from acrylic, with a cross member / metal frame underneath and four small adjustable rubber feet - the level of the floor was checked with the tray prior to building to ensure the feet were all at the required height. It needs to move approx 12" into the corner; ha anyone any ideas of the best way to go about this?

Many thanks in advance for any ideas.

Many hands make light work.

So I basically need a few assistants to assist with the lifting, I thought there must be some other way of doing, this as you can only lift the two corners of the quadrant once you have got it within about six inches of the wall.
