Concealed Cisterns and Frames

Think about the look and the space you want to free up a wall-hung frame hides the pan and clears the floor for a cleaner, minimalist look and easier cleaning, and there are 43 wall-hung compatible units in the range. Floor-standing frames suit traditional pans or where you need greater structural support, while a concealed cistern in a furniture unit gives a neat, integrated vanity finish. Frames give ultra-stability for wall-hung pans, whereas a furniture cistern is ideal in a small cloakroom where you want storage combined with the cistern. If you want a designer bathroom feel, go wall-hung; if you prefer cupboards and worktop space, pick a furniture cistern.

Frame heights vary, common options shown include 820mm, 980mm, 1090mm and 1120mm, and higher frames raise the finished pan height, which is useful if you want a taller, more accessible seat for comfort. Depth also matters some concealed cisterns and frames come in shallow 120mm depths or deeper 150mm depths, so choose 120mm if you have a slim stud wall or shallow void. An 820mm frame gives a standard WC height, while a 980mm or 1120mm frame will produce a noticeably higher seat for taller users. Match the frame height to the final pan height you prefer and the build of your wall.

Most concealed cisterns here are dual flush with 6/3 litre or 6/4 litre options, so you can use a small flush of 3 litres for liquid waste and 6 litres for solids, saving significant water compared with older single 9-litre cisterns. A 6/3 system gives the greatest saving on everyday use because the half flush is just 3 litres; 6/4 provides a slightly larger half flush that may be useful if your pan needs a stronger short flush. If water saving is a priority, choose a 6/3 dual-flush cistern; it balances performance with economy in most homes.

Some frames and cistern packs include matching dual flush plates or buttons, while others are sold as cistern-only and require you to add a plate separately. You must check the actuation type front or top actuation and whether it is pneumatic or mechanical because plates need to match that mechanism; check out the Ideal Standard ProSys offers that offers pneumatic or mechanical actuation in 120mm or 150mm depths. If you want a particular finish, there are plated options in chrome, brushed brass and black, plus round or square Alpha01 designs from Geberit. Match the plate to the frame's actuation and depth for correct function.

If you want proven reliability and extensive spare parts, the range includes well-established brands such as Geberit, Grohe and Ideal Standard, which typically sit at the mid to premium price points. Budget-friendly choices like Essentials and Wirquin offer basic concealed cisterns and buttons from around £45, whereas complete frames and designer modules from Geberit or Grohe sit from roughly £150 up to several hundred pounds, and specialist sanitary modules can be £600+. For a long-term bathroom you use every day, a reputable brand is worth the extra for build quality and parts availability; for a secondary cloakroom, a more economical option can be perfectly adequate.
