I made this circuit at my home and I found that the tranistor T1 (BC557) was not pull down at the collector terminal.
Can you help me that it is working without Pull down resistor. Because when i was making that circuit without pull down that my relay was chattering (ON and OFF rapidly). After Pull down, it works properly as you mention. I put this circuit also in my bathroom and it works perfectly. Thanks for giving such an excellent circuit idea.

Yes you can use 10kΩ for R5and R6 instead of 12kΩ?
Also can use CL100 in TO-39 metal case package for transistor T2 instead of 2N2219 in TO-39.
Regards
