Connecting 2.5 twin earth to shower 10mm

Hi, I would just like to clarify if I have figured this out correctly. So, we have removed our old electric shower, as we don't want it. This has left the connection available — it's a 10mm cable that goes back to the CU and is protected by a 40-amp breaker. I am thinking of installing a smart toilet and a Bluetooth speaker. So, could I just connect the shower 10mm cable to a connector block, and then connect some 2.5mm twin and earth to the block? I would then run the 2.5mm twin and earth wire up the wall behind the plasterboard, where it will go into the loft. From there, I plan to install a 13-amp fused switch socket, and then from that socket run 2.5mm cable to a plug socket that will power the toilet and the speakers — thus removing the need for me to replace the 10mm wire or mess with the fuse board. Thanks in advance, Steve
