Product Description

Roca Duplo One Compact Depth Concealed Cistern – A8900702A0

The Roca Duplo One Compact Depth Concealed Cistern offers a slim solution for back-to-wall toilet installations. With a depth of only 80mm, it can help save space inside a service wall, bathroom unit or suitable concealed void.

Roca designed this cistern for compatible floor-standing back-to-wall toilets. Once installed, the cistern sits out of sight behind the finished wall or furniture. As a result, the bathroom gains a clean and modern appearance.

The cistern supports several flush settings, including 4/2, 4.5/3 and 6/3 litres. Therefore, the installer can select a suitable setting during installation. It also has a front-operated flush plate position for easy use and future servicing.

Please note: This product does not include a toilet pan or operating flush plate. You will need to choose a compatible Roca Duplo One flush plate separately.

Where Can You Use This Compact Concealed Cistern?

The Roca Duplo One compact cistern may suit bathrooms, en suites, cloakrooms and other areas where space is limited. Its slim 80mm depth can also help when installing a back-to-wall toilet within a bathroom unit or shallow service wall.

This model suits compatible floor-standing back-to-wall toilets. Therefore, it does not act as a support frame for a wall-hung pan.

However, each bathroom layout differs. For this reason, ask your installer to check the toilet, flush plate and installation space before you order.

Why Choose a Compact Concealed Cistern?

A compact concealed cistern hides the main flushing system behind a wall or bathroom unit. As a result, the bathroom gains a simple and tidy appearance.

First, the 80mm depth helps save valuable installation space. Next, the dual-flush system offers a choice of water volumes. Finally, the front flush plate opening gives access to the cistern for future servicing.

A concealed cistern can also work well with fitted bathroom furniture. However, the installer must leave enough access for maintenance and follow Roca’s latest fitting instructions.

Why Choose the Roca Duplo One Cistern?

Roca is a well-known maker of bathroom products and installation systems. The Duplo One range offers a choice of compatible cisterns and operating plates for modern bathroom projects.

This compact model measures only 80mm deep. Therefore, it can provide a useful option where a standard concealed cistern may take up too much space.

In addition, the installer can choose from several flush settings. This choice helps match the cistern to a suitable toilet pan and installation.

Installation Advice

A skilled bathroom installer or plumber should fit the concealed cistern. They must secure it correctly, connect the water supply and test the complete flush system.

Before closing the wall or bathroom unit, the installer should test all connections and check for leaks. In addition, they must keep the service opening clear so the cistern remains accessible through the flush plate.
