Anyone running the Grohe shower mixer set, how's the control feel?

[Thomas Martinez]

Apparently found a walkthrough of someone testing out their Grohe mixer and hand shower set. I'm curious how these fare for people who has one in their home.
The main point of sale for Grohe mixers is supposedly the smooth operation of the handle for switching settings. They use high quality cartridges that supposedly maintain the same feel, as opposed to others who may develop a gritty feel after a year or two of use. The hand showers are somewhat straightforward, but the pressure between the two heads supposedly remains stable with Grohe versus others that may drop the pressure when switching between the two heads.
I installed a Grohe mixer myself, so does the feel last? Does anyone with one have the same experience as me where the cheapness of the materials show after a period of time? Or does it feel as good when it come time to service as when it was new when first installed? Would the cartridges be difficult to replace if they were ever damaged or worn down? I'm not about to purchase one yet but I'd like to know the experiences with these products before I can recommend to others.

had a grohtherm 1000 in my last flat for like 6 years, never touched the cartridge once. Feel was the same day i moved out as day i moved in. Hard water area too.

Cartridges are dead simple to swap tbh. 46048 or 47439 depending on which one you've got, both available everywhere, not proprietary in the nightmare sense. You can get them on amazon or any plumbing supply for like 30-40 quid.

whats the difference between the grohtherm and the grohmaster line? are the cartridges interchangeable or no?

Grohe is overpriced for what it is. Hansgrohe blows it out of the water at similar price point and the ceramic discs last longer in my experience. Fight me.

Different cartridges, not interchangeable. Grohtherm is the thermostatic line, the standard mixers use a regular cart. Don't mix them up when ordering or you'll be sending it back.

installed dozens of these. The smooth feel does last but only if you actually flush the line before commissioning. So many people skip that and then wonder why there cartridge feels gritty after 8 months of use. It's the debris from the pipework when they installed it.

lmao no. Hansgrohe and grohe are literally the same parent... Wait nvm they split in the 80s. Still though, hansgrohe better.

mine started dripping after about 4 years, swapped the cartridge in like 15 mins with a basic allen key set. Wouldnt call it a nightmare at all

what about the silverflex hoses, do those hold up or do they kink up after a while?

The pressure between the two heads is one of the better aspects of these mixers. I had one from a cheap brand in China that would halve the pressure on whichever head I used. Grohe has a much more better build quality for the diverter which is what causes the pressure difference. I’ve had mine for 3 years in hard water and it's still in great nick. I wipe it down every once in a while with a cloth soaked in vinegar.

silverflex are decent, mine never kinked but i did have to replace one after the inner liner started flaking. Like 12 quid replacement, no big deal
