I thought I would buy a greenhouse for the space at bathtub but it isnt going anywhere. So I gaveup and thinking about making a coldframe which can sit and snug on top of this tub.
I am drained of ideas to make a coldframe.

I need some ideas please  . I havent got a clue where to start.

I have got another idea of stuffing with felt on all sides and padding it which will make it look like a box planter rather than obvious bathtub (seperate project or combine it with cold frame)

Groovy bathtub - I can see why you want to convert it to a cold frame - chilly for bathing in the winter...
How about just getting some bits of pallet wood or somesuch and stapling plastic to it to make a cover? You'd nee bit about 2" wide standing on end to clear the wiggly bits on top of your bath but that should work.
Although I must admit for a back garden I'd scrap the bath or take it up the plot.
