Hi, bought a jacuzzi shower bath of ebay. Has an L-shaped shower panel
which has a thermostatic shower and extra body jets. I have three
questions about plumbing it in to a bathroom I'm building between two
bedrooms please.

1. It came with a large 3-bar shower pump but I would like to avoid
using this if possible because of wasted water and pump noise.
I have 2.5m from the top of the cold cistern to the shower head and
about 4m to the bottom of the hot tank- not plumbed in yet so can't
measure actual pressure - will this be enough (I'm not too
concerned if body jets, which can be turned off, don't work
properly)?

2. Also, there are two inlets to the shower thermostatic valve - hot
and cold. These go to the body jets and shower head. There is an
additional hot flexible pipe from the thermostatic valve. Does this go
to the bath mixer tap (it's the only place I can see to connect it
and it is not mentioned in the instructions)?

3. Would it be ok to run a hot supply directly to the bath mixer tap
(in case I need to use the pump for the shower).

Thank you
