Need help for a hot tub base

[vallumlj]

I having just bought a hot tub and want to put it onto the paving slabs we will be moving the little shed. Problem is it will go onto the artificial grass a little bit. What is the best way to make it level across the Slabs and grass?

I was thinking about about rubber matting / decking board or should I just remove the grey concrete edge.

Any advice would be great thank you

suspect you will need a foundation possibly concrete or similarly specked decking what size and weight is the fully loaded tub
