Looking for reliable experienced contractors. The door position cannot be shifted based on personal preferences.
I am forwarding a layout of the bathroom. Appreciate any comments/recommendations

Currently, the shower is near the door and floor trap near WC, meaning whole toilet floor will be wet...beside door (before exit) and also wet at WC (if using it after shower).
Ideally separate dry from wet, which for small toilet is harder to do.
So shifting shower deeper inside toilet is good idea, with dedicated floor trap, kerb or sunken shower floor, and shower screen/curtain (option).
May have another floor trap between basin & repositioned WC.
What's the room width? If orientate WC that way, need at least 1m for knee/leg space for average sized person, or more if bigger sized.
Door position, ideally don't face WC but basin.
If this toilet is on ground floor you will have to hack more of the floor slab to lay the sewer pipe, so might as well do more improvement.
The exhaust fan is good, not only for extracting smell but also moisture (prevent molding and paint wear)
