Description
Create a tidy back-to-wall toilet installation without a visible cistern. The Tavistock Vortex VOR790 concealed cistern has a slimline 135mm depth to help make the most of the space inside bathroom furniture. Its insulated body helps reduce condensation, while pneumatic dual flush operation offers a choice of 3 or 6 litres.
A pre-assembled design and bottom-entry inlet help simplify installation. Top and front access points allow for servicing, provided suitable access is retained in the finished furniture installation.

Installation & Compatibility
Intended for suitable back-to-wall toilet and bathroom furniture installations. Ask your installer to confirm the pan connection, internal furniture space, inlet position and flush-control requirements before ordering. The 135mm measurement is the cistern depth, not a guarantee that a finished installation will fit within a 135mm void.
Retain suitable access to the inlet and flush valves for maintenance. Match any replacement or alternative button to the pneumatic mechanism and check its connections, mounting opening and clearance before fitting. Mechanical rod-operated buttons are not interchangeable simply because they offer dual flush.
Frequently Asked Questions
Will this fit my back-to-wall toilet unit?
Check the unit's internal dimensions and the pan and pipe connections with your installer. The cistern is listed as 434mm wide and 135mm deep, but additional space is needed for connections, fitting and maintenance. Contact us with your toilet and furniture model if you need help checking suitability.
How does the dual flush work?
The pneumatic mechanism provides a 3 litre reduced flush and a 6 litre full flush, selected using a compatible pneumatic control.
Is it suitable for a low-pressure water supply?
The listed operating range is 0.2–10.0 bar. Your installer should confirm that the supply pressure and installation meet the cistern's requirements.
Does the insulation prevent all condensation?
The insulated body helps reduce condensation. Bathroom ventilation and the difference between incoming water and room temperatures also affect condensation.
Is a flush button included?
The current listing does not confirm the supplied button or actuator. Before ordering a separate control, email customerservice@bubblegumbathrooms.co.uk or call 01603 381095 so we can confirm the supplied contents and suitable options.

Yes. This non-clearance item can be ordered when out of stock, subject to supplier availability. For a current lead time, email customerservice@bubblegumbathrooms.co.uk or call 01603 381095.
