IN-WASH® WITH IN-TANK®, a cisternless toilet for the smart bathroom

Take a close look at the cisternless smart toilet that combines the WC and bidet functionality

As well as customisable functions and easy to use technology, Roca’s In-Wash® smart toilet is available with In-Tank® innovation for the ultimate smart bathroom. Cistern-free, In-Wash® with In-Tank® is even easier to install and clean. Learn more about the benefits of In-Wash with In-Tank® technology below.

There are two In-Wash® models with In-Tank® technology; wall-hung ang back-to-wall. Both are cisternless, as the In-Tank® technology integrates the water tank into the bowl.

Also, as it doesn’t require a frame, the In-Wash® with In-Tank® increases the installation possibilities of the WC and allows users to save space because, without the cistern, the WC takes up between 10 and 20cm less space.

Its Rimless Vortex design generates a powerful flush with a 360° water flow that covers the entire bowl providing an optimum flush with the minimum amount of water. Additionally, this smart toilet incorporates the Supraglaze® coating, which prevents the buildup of dirt and allows any residue to slide right off. An additional layer over the traditional glaze results in a waterproof, shiny and extremely smooth surface, which is very easy to clean.


Customisation is one of the most outstanding features of this smart toilet. Combining a WC with the functionality of a bidet, the In-Wash® cleaning nozzle can be adjusted to five different positions according to your preference, guaranteeing full intimate hygiene. The pressure of the water flow has three intensity levels and the temperature can be set to 33ºC, 36ºC or 39ºC. Finally, In-Wash® includes a hot air drying function, which can also be adjusted to three levels.


In-Wash® can be activated using the side panel at the rear of the WC, or the remote control which can be magnetically attached to a wall bracket. Simple and intuitive, the side panel has three buttons for simplicity. The remote control, on the other hand, allows users to customize the positions of the nozzle, the water temperature and pressure.

Roca’s smart toilet features an infrared sensor that activates when it detects a presence on the seat, ensuring that the washing and drying functions only start up when necessary. The smart toilet also has LED lights, which can be adjusted to stay on for 8 hours and in 4 different modes, ensuring safety and comfort at night in your smart bathroom.


Installing an In-Wash® with In-Tank® cisternless toilet is much easier than you might imagine. It only requires a conventional power supply and a water outlet. Compact and minimalistic, you can install the In-Wash® floorstanding and wall-hung models in no time.
