How to Install Wall Mounted Toilets & Sinks on Dot & Dab Walls

  1. Mark required location of toilet or sink fixing holes, these are normally pre drilled or the manufacturers will supply separate fixing plates / brackets. Separate wall brackets can also be secured using Corefix. A minimum of four Corefix dot & dab wall fixings should be used per toilet and two per sink unit. Drill hole to required depth using a 10mm masonry or SDS drill bit.
  2. Ensure all debris and dust has been removed from the hole. Gently tap the Corefix plug into place until the flange contacts the wall surface.
  3. Then tap the metal core into place until it is flush with the Corefix plug flange.
  4. Offer the toilet or sink up to the wall ensuring two people support any heavy items and screw back to the wall using the supplied screws. Ensure toilet or sink are secure and that screws are ‘tightened up’ in all fixing locations.

Will Corefix Support my Wall Hung Toliet or Sink?

Corefix was developed over two years and has been specifically designed to carry extra heavy loads on dot and dab / cavity walls. The steel core in this plasterboard fixing transfers the load from the board to the solid blockwork or masonry material behind and whilst other frame fixings claim to perform the same role these can severely distort or crush the plasterboard into the void. A wall hung toilet should be supported on four fixings and Corefix has been tested to support 250kg on four fixings.
