WC Pan Compatibility — What to Check Before Ordering

A concealed cistern frame must be dimensionally compatible with the WC pan it supports. The critical compatibility parameters are:

Pan fixing bolt centres: The two horizontal bolts that project from the frame front face (onto which the WC pan slides) must match the fixing holes in the pan. The most common standard is 180mm centre-to-centre between the two bolts — used by Geberit, Grohe, Vitra, and most universal-format pans. Some manufacturer-specific frames use 230mm fixing centres. Confirm the G35's bolt fixing centres against your chosen WC pan's fixing hole spacing before purchasing.
Waste outlet height: The WC pan's P-trap or S-trap waste outlet connects to the soil pipe at a set height from the finished floor. The G35 frame's waste connection height must align with your wall's soil pipe entry point. Standard concealed frame waste outlet heights are typically 180–230mm from the finished floor level — confirm this matches your soil pipe centre during the planning stage.
Frame height adjustability: The G35 offers adjustable installation height, allowing the finished WC pan seat height to be set between approximately 390mm and 430mm from finished floor level — compliant with the UK Building Regulations Approved Document M range of 400–450mm for accessible WC provision.

Tool-Free Water Connections — What This Means in Practice

The G35's "tool-free" connection feature refers specifically to the push-fit or hand-tight connection points for the water supply inlet and the inspection shaft access cover — not to the entire installation process.

In practice this means:

The water supply inlet valve connects to the mains supply pipe using a push-fit or compression fitting that does not require spanners or specialist tools that reduce the risk of over-tightening and cracking the HDPE inlet port
The inspection shaft (the access point through which the cistern's internal components include float valve, flush valve, dual flush mechanism , can be reached after wall boarding is complete) opens and closes without tools, allowing future maintenance access without disturbing the wall finish

What still requires tools: The steel frame floor and wall anchors require drilling and torquing to specification. The flush plate fixing to the wall board requires screws. The soil pipe connection requires standard plumbing tools. "Tool-free" applies to the cistern water connections only — not to the structural installation.

Why the inspection shaft matters: Once the frame is installed and the wall is boarded and tiled, the cistern's internal mechanisms must be serviceable without demolishing the wall. The inspection shaft provides a pre-formed access route through the wall finish — typically a 150–200mm square opening behind the flush plate — through which the float valve, flush mechanism, and overflow can be inspected, adjusted, or replaced. All quality concealed cistern frames include this feature; confirm shaft dimensions with Durovin to ensure access tools fit.

Key advantage of the G35: The flush plate is included in the package — with Geberit and Grohe, the flush plate (the visible button/panel on the wall) is sold separately, typically adding £30–£150 to the total cost. The G35’s all-in-one package reduces overall procurement cost for standard residential installations.

Key consideration: The 350kg load rating is lower than the 400kg standard of Geberit and Grohe systems , relevant for commercial or high-traffic environments, but fully adequate for typical residential use.

Wall Void & Structural Requirements — G35 Frame

Wall void depth:

The G35 frame body is 118mm deep — one of the slimmest concealed frame profiles available
Adding wall board (12.5mm plasterboard) and wall tiles (8–12mm tile + 3–5mm adhesive) brings the total wall build-up to approximately 145–150mm
Minimum stud wall or false wall void required: 150mm internal clear depth
For solid masonry walls, a false (studwork) partition wall must be constructed in front of the masonry to house the frame — standard practice for concealed cistern installations

Floor fixing (critical):

The frame’s two floor anchor feet must be fixed into solid concrete slab or dense screed
Do not fix into floating floor boards, timber joists, or unsupported screed — the 350kg dynamic load requires a rigid anchor
Use supplied floor fixing bolts or M10 stainless steel anchor bolts into concrete

Wall fixing:

The frame’s upper support arm fixes to the wall structure (stud, noggin, or masonry) to provide lateral stability
This fixing does not carry primary load — load is transferred through the floor anchors
Ensure the fixing point hits a solid structure — not plasterboard alone

Soil pipe alignment:

The waste outlet must align with the centre of the soil pipe in the wall
Typical wall-hung soil pipe centre height: 180–230mm from finished floor level
Set frame position accordingly before final fixing

Estimated installation time:

2–4 hours for frame, cistern, and rough plumbing connections by a qualified installer. Wall boarding, tiling, and flush plate installation are separate stages and timescales.
