I flew back from BOM this morning in CW.
I asked for an Infinity Bath at the arrivals lounge and a not so nice lady looked at me as if it was an annoying question, then said "but there is only a bath in there, no shower". Eventually she went to check if any of the cabanas were free and she gave me number 2. She didn't offer to fill the tub the tub for me, neither she made me feel welcome. I may report this to BA, hoping in some sort of Avios compensation. :-)
I used the tub for a shower rather than a bath, and I have to say that the cabana was lovely. I made a video I may post.
It was my first time in CW and I wasn't aware of the ironing service in the cabana. If I'd know I would've tried that as well!
