Thermostatic shower mixer and diverter to bath/showerhead

[Matthew Barnard]

I am installing a new bathroom suite. Low pressure water supply and hot and cold storage tanks. For various reasons I intend to install a thermostatic shower mixer, the output of which will fill the bath. Ideally I would also like a separate shower head attachment for (low pressure) rinsing. Both of these will be entirely separate (physically and plumbing connections) from a (venturi) overhead shower.

I could use a triple thermostatic shower mixer. However my preferred model only has a double mixer (one output) and optional diverters. My question is - is it feasible to use a thermostatic mixer plus diverter on a low pressure system? The mixer is specified to be used on low pressure - and of course will only be used to fill the bath or supply a low pressure rinser. Not sure of the difference in flow rates/resistance between triple thermostatic mixer and double mixer plus diverter....

What sort of head height and pressure are you actually getting at the bathroom supplies?

The mixer you need is a dual flow one, like the type that allows you to lift a plunger on the tap body and lets water out the shower riser.

I think your making things to complicated, going by your description anyway, and an easier solution should be planned. The more you complicated the job, the more problems you'll have.
