The basic rod is 157.4 cm long. Between the edge of the bath and the ceiling I had 180 cm, which was quite feasible. However, I can't tell you whether it will also work in your case, where it only needs an extension of 10 cm including the suspension. In any case, the Simplehuman shower caddy is the best, most stable and elegant shower rail we have ever used. We can absolutely recommend it. The price-performance ratio is right.

In the Quick Start Guide, simple human writes the mount is possible from 183 up to 211 cm.

I didn't measure it myself, but my pole also stands on the edge of the bathtub and the installation went without a hitch.
