Marcio,
Glad to hear you've got it all sorted out safely now.
A neighbor has been refurbishing his house and I wired the new electric shower in a few weeks ago. While the bathroom was out of commission he was using a friend's bathroom just around the corner. His friend had done a lot of his own wiring (no proper grounding, bonding etc.) and he said he was glad to get his bathroom wiring done as he felt safe getting under the shower again!
