Vibration from a pumped digital shower

[newboy99]

Hi Guys
I'm installing a pumped digital shower unit (Mira) and because of space restrictions, need to locate the actual mixer / pump unit under the bath.
I know from experience that these can be fairly noisy and cause vibration.
Any suggestions as to what I could sit it on to reduce both ?
A thick piece of rubber sounds as though it would do the trick but where could I get a piece ??
Or is there something better and more easily obtained ?
Any ideas appreciated !
Many thanks for your help.

Go for the 55-grade memory foam, it's got better energy absorption properties. 1" thick will probably be OK but if you've got the space go for the 2" just to be sure. 99p delivered for a 12" square piece of either, which will be the perfect size for most shower pumps
