Godalming Date: September 16, 2015

Great item, competitively 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.

Giles Asked :
Hi, Can you access the Geberit Duofix WC Frame 112cm With Sigma UP320 Cistern 12cm-111.384.00.5 from the top if needed and a push-button pneumatic flush used instead of a flush plate, e.g., Thanks, Giles

Answered By QS Team :
Unfortunately, you cannot access inside the cistern from the top on the Sigma 12cm (111.384.00.5). You can use a pneumatic button with the above Sigma 12cm cistern rather than a flush plate.

Ailsa Asked :
Can you fit this into a corner?

Answered By QS Team :
No, you can't fit into this corner, because it's not designed for it, but you may need one with corner fittings, and the manufacturing code of the product is 111.399.00.5

Zoe Asked :
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 wall-hung WC’s

Sarah Asked :
For the Geberit 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.
