My maid does thoroughly washing twice a week for common toilet which we bath in daily and once a week for master room toilet which we seldom use to shower.
On daily basis, my maid will do a quick wash of the shower area after her shower cos she's usually the last to shower. She'll just rinse the toilet and use a cloth to wipe clean.
We only have a small cabinet in MBR toilet which she wipes once a week. For common toilet, we avoided building anything in there.
