Frequently asked questions
Do I need the concealed body?
Yes, for a new installation it is mandatory. Choose “Complete set with concealed body”. The “External part only” option is only for those who already have the Treemme concealed body installed in the wall.
Which handle should I choose?
In the Handle menu, you can choose the Piccadilly metal lever or the lever with a white ceramic handle, which is more classic. The ceramic handle has a small additional cost, already included in the price. For the brushed brass finish, the ceramic handle is not available.
How is it installed?
Installation is carried out by a plumber. For concealed models, the body is built into the wall before tiling, and the external part is installed at the end.
