I didn't have a shower as such but some of the best gifts we were given were:

* Large stretchy wraps. A godsend when trying to get them off to sleep.
* Gift voucher at a baby store
* Monitor (didn't think we'd use one but I find it really handy for when I'm in the shower or just to hear when he's coming out of one sleep cycle to go in early and try and resettle him into the second one)
* Massage voucher (haven't used it yet but I need to!)
* A personalised towel (I think there's a website where you can order them)
* Body shop (or similar) gift pack - although thats a good gift for when you visit in hospital too. It's always nice to remember mum as well as bub.

Other things we weren't given but have needed and use everyday would be things like cot linen, blankets etc.
