What size shower do you have , if its 9kw or bigger , then it should be wired in 10mm cable , it is quite common for the pull switches to burn out , it is good practice to switch them off when not in use , as it reduces the chance of them arching out .
Rather than use a standard 30A junction box , get a 150mm by 150mm plastic adaptable box from an electrical wholesaler , and get 50A rated terminal blocks , just make sure the junction box is accessible for future inspection , i would preferably use through crimps if you have a suitable crimping tool .
