CERA Chevron Concealed Cistern Set with Half Frame (B1110112) is a slim dual-flush concealed cistern supplied in a half frame — a more compact, lower-cost mounting designed for bathrooms that already have a solid wall to build into.
The difference between half and full frame is structural, and it matters. A half frame does not carry the load on its own — it transfers the weight of the pan and user into the solid brick or concrete wall behind it. That makes it the efficient choice when you have a masonry wall and can cut or build a recess into it, since you're not paying for structure the wall already provides. But it also means it is not suitable for stud partitions or drywall, where there is nothing solid to take the load. In that situation you need the full frame version (B1110111).
Everything else matches the full-frame set: a slim cistern profile designed to sit in a shallow recess, a dual-flush mechanism, and a finished result where only the pan and flush knob are visible.
Before You Order — Two Things to Check
- Your wall must be solid. A half frame relies on brick or concrete behind it to carry the pan's load. On a stud or drywall partition it is unsafe — use the full frame version, B1110111, instead
- No actuator knob is included. Choose an H, M or Q type knob separately — the cistern cannot be flushed without one
- You will also need the wall hung EWC itself, such as the CERA Carlton or Carnival Rimless
- All of it must be settled before first-fix plumbing, because the cistern and frame are built into the wall and tiled over
- Not sure what your wall is made of? Ask your contractor before ordering, or send us photos and we'll help
Key Features
- Compact half frame: Less structure and lower cost where a solid wall already carries the load
- Dual flush: Full or reduced flush selectable, reducing water use
- Slim cistern profile: Fits within a shallow masonry recess
- Discharge pipe, adapter sleeve and protection cap included
- Concealed installation: Only the pan and flush knob remain visible
- Shallower build-out: Takes less room off the bathroom than a free-standing frame

Half Frame or Full Frame?
| Frame | Cat. No. | How it carries the load | Use when |
|---|---|---|---|
| Half frame | B1110112 | Relies on a solid wall behind to take the load | Solid brick or concrete walls, where a recess can be cut |
| Full frame | B1110111 | Self-supporting — fixed to floor and wall, carries the load itself | Stud partitions, drywall, non-load-bearing walls |
Choosing wrongly here is a safety issue, not a preference. A half frame on a partition wall can fail under load. Confirm your wall construction with your plumber or contractor before ordering.
Recommended Applications
Where this fits best
- Solid brick or concrete walls: Where the wall itself can carry the load
- Independent houses: Typically built with solid masonry internal walls
- Renovations in older buildings: Where walls are solid and a recess can be cut
- Tight bathrooms: Shallower build-out than a free-standing frame
- Cost-conscious projects: Less structure where the wall already provides it
1) Does this include the flush knob?
No. This set is supplied without an actuator knob — choose H, M or Q type separately in shine finish. Without one the cistern cannot be flushed.
2) Can I use a half frame on a plasterboard or stud wall?
No, and this matters for safety. A half frame transfers the pan's load into the wall behind it, so it needs solid brick or concrete. On a stud or drywall partition, use the full frame version (B1110111), which is self-supporting.
3) Why choose half frame over full frame?
If you already have a solid wall, a half frame is more compact and lower cost because you aren't paying for structure the wall already provides. It also builds out less far into the room, which helps in a tight bathroom.
4) What else do I need for a complete installation?
A wall hung EWC (the pan) and an actuator knob, both sold separately. Together with this set, that's three purchases for one working toilet — all to be decided before your plumber starts.
5) How do I service the cistern once it's tiled in?
Through the knob opening. The actuator knob plate removes to give access to the flush valve and inlet, so routine servicing doesn't require breaking tiles. That's why the knob opening position needs to stay accessible and unobstructed.
