Can you roll it like dumdum or bluetac to make a lump to fill a small space that's a bit bigger than the 3mm thick?

Yes as long as you set your hands.

Hi. How thick is the tape? Thank you.

3.5mm thick, 1 inch wide and 33 feet for roll size. The butyl tape is double sided, putty like for water and air tight seal.

Hi can I use around the bath

Not designed for a bath but there are similar products that are designed for baths

Could I use this to stop a leak in a shower from between grout, there is movement on the shower tray so I need something flexible?

I would certainly give it a try. Ive used it my windscreen where the seal has perished. works great. Not sure how easy it is to remove. Might use on my shower when the glass has broken free of the old mastic. Bought it to fix the rainscreen back into the car doors. Perfect.
