Drywall, or wallboard, also called plasterboard or gypsum board, is a common building material used in interiors for constructing walls and ceilings. Drywall is gypsum plaster in the middle with layers of paper or fiberglass mats on either side. Drywalls do not need mortar or plaster. The gypsum core is rigid, and the other surface is smooth.

Does this come with the loo seat and flush plate, as well as the frame and cistern, or do I need to buy those two things separately? Is there anything else I would need to add to make this all?

Richard Asked :

Can the soil pipe exit the frame to the right or left, not straight down? Is this suitable for a rimless toilet?

Answered By QS Team Answered by the QS Technical Team

Yes, the soil pipe can be rotated in the frame and locked into place to go sideways. These are fine to use with a rimless pan.

Ian Asked :

Can the Geberit Duofix 980mm frame be used to support a Roca Meridian wall-hung toilet?

Answered By QS Team Answered by the QS Technical Team

Yes, Duofix 980mm will be able to support the WC pan as the Roca Meridan wall hung has bolt-hole centres of 180mm, and the Duofix 980mm WC frame has 180 or 230mm bolt-hole centres.

Karen Asked :

I want to buy the Duravit Architec wall-mounted toilet and Geberit Sigma20 dual flush plate. Will the Geberit duo fix wall-hung 980 frame and concealed cistern be compatible?

Answered By QS Team Answered by the QS Technical Team

The Geberit Duofix you choose needs to have the Sigma cistern, so the flush plate you selected will fit. The Duravit wall-mounted toilet has the fixing holes in the right place to be attached to the Duofix frame; however, as it isn't one of Geberit's products, we cannot guarantee it, but it should all line up and fit.
