well, if you average out the load the shower draws over a period of time, a 6 amp MCB would be plenty sufficientsecurespark said:Who taught you that diversity can be applied to a fixed load?

35 or so Amps of Current - and Lots of Spraying Water = Potential Risk of Shock.
Fit your MCB to the RCD side of your consumer unit (if it has one), failing that, add a 40A 30mA RCBO (if you can get one that fits!) - or if not then fit a seperate shower CU by taking a 40A feed from your current CU , or if you can't do that then split the tails before your consumer unit and add the shower unit using Henley service blocks!
The bathroom is a special location - do you know this work should be notified to the council and also any work should be checked & tested.
Are you up to the job?? Are you also aware that if you don't have it tested then peoples lives are at risk , can you live with yourself knowing somebody electrocute themselves because your setup (FUSES!!!!) may not disconnect from the supply within the times specified by BS 7671 (0.4 seconds or 5 seconds!! - equipment dependent.
Why not get a spark in, ask him if you can run the cabling etc (under his supervision/guidance) - then get him to do the final connections and issue you with your test certs etc!
Would be worth it in my mind! But its up to you - your house!
