are there different types of HDPE pipes that I need to take note of? I only know the ones with blue stripe. By the way, how many mm are the pipes supposed to be? 15mm?

considering to get this, inclusive delivery and tax from Amazon DE it's EUR 900, this should be all I need other than the piping works right? local Grohe dealer selling at RM7,888 no discount

My bad. I actually used PP-R (suitable for hot water) that usually greyish colour with blue/red stripe. i think the stripes is to differentiate the cold (blue) and hot (red) line. Get those good grade with SIRIM approval. And installer also playing an important role. Get an experienced plumber for the job. Once the lines done, close all the points and do leak test with your pump on. i cannot remember the diameter of the pipe but i think there are some cut-out portion and i am keeping. Later i check and let you know.
HDPE is those black pipe with blue stripe. Sorry that i made you confuse.

The picture you showed is actually conceal type and installation will need to hack off the wall with sufficient thickness in order to cover the whole internal unit.
Very nice to see but if there is problem with the conceal unit arise then you will need to hack the tile and do rectification. If you really want this type, get a reputable and decent one and good one usually expensive. All my bathroom and toilet parts bought locally and thus I am not familiar of getting from Amazon. Anyway RM7888 can get a whole bathroom renovated complete with everything.

This looks really nice.. Posting to get notified of future discussions.. Looking forward to seeing your final result. Good info shared thus far.

will definitely try to get a plumber to do PP-R! Very hard to find plumbers willing to do PP-R I feel (even when I wanted to install pump)

based on my understanding for the conceal type.. need to hack if pipe inside leaking.. which should be unlikely.. if mixer failure then perhaps can find back the same parts.. coz aesthetics wise conceal is so much nicer

a LYNer pointed out to me that this has no volume control only on/off which is making me hold back a bit, Grohe has volume control but that brand slave in me is telling me to get the fancier hansgrohe hahahaha

I had to rewatch the video again to be sure.. Initially, I simply assumed it would have volume control.. As in, why not.. who doesn’t need volume control in a shower set? Unless they expect a separate control knob to be built alongside?



From the SS above, she pushes the lever on the bottom first before adjusting.. Guess I wrongly assumed it is some pull/push mechanism to control the water volume..hmm. Also, I can relate to the fancier bit.. haha

The button is to disengage the temperature limiter which in this case set at 40oC. She was taking shower at temperature more than 40oC which is scalding hot

Newer hansgrohe model with thermostat control, volume control and 3 select switches.....(if ur rain shower got 2 spray modes, lesser switch lower the price)

P/S: the price is just only the thermostat unit, u still need to add on a hand shower n a rain shower unit.......

Difference of switch and those turning knob is that turning knob can onli turn on 1 shower each time, but select switch, u can click all n on all...... of coz water pressure will affect the water power.... mostly for u to play wif multifunction/multi spray type rain shower.....

That's the fancier hansgrohe.....
