Water supply

The direction of flow water supply provided in the installation. There are many constructs that allow for multiple variants at once - for example, above and rearToilet. The toilet bowl is usually a hanging bowl. Provided for in the relevant models (cf. above). The advantage of this configuration is obvious: the «native» toilet by definition is optimal for installation, it does not need to be searched and selected separately. On the other hand, the complete bowl may not be suitable in shape or any features, so its characteristics do not hurt to clarify before buying.

Tank. Own tank, optimally sized and shaped for this installation. May have various special functions (cf. «Rinse»), they should be specified separately.

Bidet. The fixed module is initially equipped with a bidet. The main advantage of pre-installed bidet installations is the absence of the need to select the plumbing separately - in this case, the standard bidet is ideal for installation in terms of size, weight and functionality.

Flush button. Its own flush button is provided only in models originally equipped with a tank (see above). The flush is designed in accordance with the design. The design of this part corresponds to the functions of the tank: for example, in models with two-mode flush, the control key is usually also double. Recall that the flush button is located outside, so before you buy it is worth making sure that it...fits into the design of the bathroom.

Soundproof pad. A special gasket placed between the installation and the bulkhead covering it to muffle the sound - first of all the noise of the water collected in the drain tank.

Drain tank volume

The volume of the drain tank provided in the installation.

The larger volume, on the one hand, allows for better flushing, on the other - affects the water consumption and tank dimensions. In addition, with relatively small bowls, it does not require much water. Most installations use tanks of 6 to 10 liters - these indicators are considered optimal in the light of the described features.
