We needed to go for the slimmest possible solution for the en-suite we were building, and this fitted the bill perfectly. Although more expensive than other brands, it was worth spending the extra to guarantee it would fit in the CLS stud work and was straightforward to fit and plumb in. Having the cistern in the wall makes all the difference in such a small room and makes it feel bigger than it is. Overall, I’ve been really impressed with it and will definitely be fitting another one in the main bathroom when I do it up.
The duofix I installed was easy and straightforward for a first r. The instructions were clear and the product itself has a substantial and well engineered feel to it which brings price of mind as it is installed in a very expensive bathroom. Almost 2 years on, and the frame/ cistern is performing well, there have been no issues.
Great bit of kit, good quality, powerful flush! Installation instructions are difficult to interpret, and I'm a plumber. Also, the Horizontal option for the waste pipe cannot be secured using the collar provided; therefore, this item is not recommended for the DIY enthusiast.
Excellent product, cheapest on web. Works well with Duravit toilets and geberit flush plates. Easy to fit and gives a clean uncomplicated look to the bathroom.

Geberit Sigma70 Soft-Touch Dual will not go with article 111.799.00.1. You can use Article 115.627.XX.1 (XX - to be replaced with finish code). We would not be able to advise on if the pan is suitable, but please see drawings in the PDF given below.
