Showering with hickman line

I had a Hickman line fitted 3 weeks ago and have now had both stitches removed. The nurse has just put 2 strips of tape on the tubing but I don’t have any dressings on. I forgot to ask whether I need a waterproof dressing on when I take a shower or whether it’s ok to just leave it as it is. 

Has anyone else got a line and can tell me what they do please.

I had a PICC not a Hickman and had a waterproof sleeve to put on my arm.

 

I did have a quick Google about it and everyone seems to have a bath and not let the site sit in the water!
