Replacement for Triton Biarritz Shower

Ash_Pole

My shower unit (Triton Biarritz) is old and now obsolete. I'm trying to work out what a direct replacement unit is with cables and plumbing in from the back, but Google is failing me.

Bit of a longshot but can anyone help?

I thought most Triton showers were backwards compatible

According to Triton, this one should be a direct replacement - https://www.tritonshowers.co.uk/t80si-electric-shower

I fitted a Triton T80Z Thermostatic shower a few years back when an old (not Triton) stopped working. At the time, I considered the thermostatic control to be well worth the money. But the price have gone up considerably (think I paid about £150).
