High quality German made . We have some of these shower pipes/ air heads that are now coming up to 15yrs old . No marking or dulling of chrome , same thermostatic cartridges . You'd be lucky to get 5-10 out of a Mira or Bristan .

Don't confuse this with grohe , same family origin but big difference in quality

I've had a look at several Hansgrohe fixed overhead showers online, and those with the lowest flow rates appear to be:

Hansgrohe Croma 160. Model: 27135000
and
Hansgrohe Croma Select E 180. Model: 27256400

Both have an overhead shower rate of 16 litres/minute.

I read online in relation to the first model above that it is suitable for continuous flow water heaters, if the flow pressure at the mixer is a minimum 0,15 MPa / 12 litres / min.

My new WBosch combi boiler has a given flow rate of up to 12.3Ltr/min. Also, I'm located in a high pressure mains gas supply area which I discovered when being connected to the gas supply.

Do you think the combi would be adequate for one of the above overhead showers? Should I measure the water flow currently from the bathroom sink, would that give any additional useful info?

I've read before that sometimes a combi boiler with an overhead shower requires a 3 bar pump and 3/4" feeds, with a Hot Water circulation loop, to the H&C. Would this be required?

A combi giving 12l is more than sufficient for the linked item

The croma heads are on par with Mira , these are plastic and not solid brass like the one I linked to

You can't pump a combi, nor would you use anything other than 15mm supplies, it would take forever to come through warm

From your other posts your making a mountain out of a molehill !!

Okay, thanks.

Thanks for pointing that out. I hadn't realised that. I'd just assumed the lower price point was due to the lower flow rate.

I had been reading the following webpage, so I'd thought perhaps I would require an overhead shower which had quite a low flow rate, or a pump.

I noticed that when the brandname Hansgrohe is typed into eBay it brings up many component parts.

http://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=Hansgrohe&_pgn=2&_skc=50&rt=nc

Since the wall I'm considering installing the shower on is a cavity wall, would it be possible to purchase the individual parts for a shower and install these so that the pipework is hidden behind the cavity wall?

Is there any particular advantage in doing this as opposed to having the revealed showerpipe?

Or is it really just an aesthetic difference?

Make sure and call in to soaks on the Boucher Rod if you're going to go for Hansgrohe. See if they can do a deal.


I'm getting a new bathroom fitted next week and went for the raindance overhead. Also bought a Hansgrohe taps, hand shower and rail.


Looks good quality.

It's not just pressure you need for a shower head over 100mm . You need flow

Average combi will do 9-13 litres of hot water so you should be fine

Hansgrohe made the air system that makes it feel like your using twice the water flow , cross water use similar technology , Mira have flip handsets but nothing that compares on the larger fixed heads

Tempted for that...I'm about to start replacing my bathroom. Price seems good 1300 down to 400GBP. My last thermostatic one was less than £150 from ebay and the quality wasn't great. Thanks for posting the link!

Since the Raindance unit has a hand shower, I wonder is it still also good to have a hand shower attached to the bath taps?

Or since the showerpipe has a hand shower perhaps there would be no requirement for an additional handshower attached to the taps?

I was toying with the idea of having the handshower on the taps as well , the only reason I could come up with to have it was if you are in the bath it's easy to wash your hair without reaching up to switch shower on.

I'm having centre taps with end shower so slightly more in favour of having both, in the end I didn't bother as I wanted it less cluttered.
