Great item, competetitively priced and delivered fast.
Very happy with this item after 3 months of installation. Competitively priced and fast delivery. The only thing I would say with QS is to be aware that items often come from third-party suppliers, so,if there's a delay receiving an item, it can be difficult getting accurate information as to when it will be dispatched. Not so much an issue for us for this item but it was for other elements of our new bathroom.

Waste of money.
This is a good quality item but is sold with out the necessary fixing clamps which you have to buy separately or you can buy it combined together as a package for less money than having to buy it separately.

Is this frame compatible with a back to wall wc? We already have the frame installed with a wall hung wc. We are considering changing the wc as we are not confident that the frame has been installed correctly. Many thanks.

Answered By QS Team :
No Geberit frames are not compatible with Back to wall WC’s, they are compatible with only only wall hung WC’s

Was this answer helpful? Yes - No

For the gerberit duofix, is the frame strong enough to support the use of a wall hung toilet bowl, without building a wall? Thanks.

Answered By QS Team :
Thank you for your email. The frame is designed to take 300Kg in weight, but must be fixed securely to both rear wall surface and a floor surface. I am unsure what exactly you are asking or proposing to do with this frame installation

Was this answer helpful? Yes - No

Dear Sir/Madam, I am interested in your 1.12M WC FRAME & CISTERN. I am trying to figure out the minimum depth of the required box (over all dimensions from back wall to the front of the box). It seems that this would be 192mm, provided we use the smallest pipe size on the bottom (specified by the technical drawing between 9 and 13.5cm). Is that correct? Is there a way to reduce this 192mm further down? Thank you very much for your help, Theo Svoronos

Answered By QS Team :
I have attached a copy of the installation guide for the 111.384.00.5. It depicts different installation scenarios that may occur on site. The minimum install depth required for this particular frame is 135mm. I hope this helps.

Was this answer helpful? Yes - No

what is the depth of the unit, please?

Answered By QS Team :
The depth is 120mm.

Was this answer helpful? Yes - No

I'd like to buy this Geberit wc frame, could you, please, just let me know which Geberit flush plate would match this? I'm looking to have possibly a dual flush plate in a chrome finish.

Answered By QS Team :
Please search our website for UP320 Flush Plates. There is a huge choice and also price variation. You could choose QS-V19171 which is a dual flush suitable for your need.
