July 6, 20215 yr I’m told that Grohe’s new Rapid SLX concealed framed cistern is the quietest cistern on the market now so it seems very appealing. Has anyone had one? Is there a difference in quietness or is it a bit of a sales gimmick? And this may be a silly question but is this cistern compatible with any wall hung WC that is attached to it? Or does any brand WC like RAK or Duravit fit onto this new Grohe concealed cistern?
July 7, 20215 yr Sounds like a bit of a sales gimmick Theres such a small amount of water in the concealed systems Ours have refilled before I’ve finished washing my hands
July 7, 20215 yr Grohe Wc frames take most makes of wall hung pan and I have found company below very good to order from!! https://www.plumbingforless.co.uk/bathrooms/toilets/toilet-frames-sets/grohe-rapid-sl-3-in-1-wc-set-incl.-1.13m-concealed-frame-and-cistern-38772-001
July 7, 20215 yr Author Thank you @JOE187 That’s only the SL model though. I’m looking at the SLX model. It’s been given an official Quiet Mark Approval seal so must have met certain criteria to pass that.
