Possible to move WC for landed unit, but not for high rise unit.

Use shower curtain instead of permanent screen. The railing can be made to any shape to fit the space and not necessary straight so that there is more room space.

You didnt answer post #2, so we all assumed is highrise and the answer is no

there is a concept of placing a wash basin outside the bathroom (depending on the room layout). then you'll get bigger space for the wc and shower.

U can already use the water now right? If u think the water is not filing fast enough then u will need a pump. U can check with the shop by telling them how many toilets and kitchen. They will propose u the pump size.

This is the rain water tank right. Mayb u can check with the agent. Press them to giv u the answer

Like another member mentioned, the WC is probably there so the door can clear when open/close. Change it to a folding door. I did that for my small bathroom and it “felt” more spacious cause it makes getting in and out feel easier.

Just curious do you have the measurements for your bathroom? Really does look small.

haiz, my WC just done reno, and shift the toilet bowl (sit type) to side, i noticed that the water orientation is slow flowing, poop cant be flush like usual, like i have to flush 2 time for a clean look,  now the toilet got jammed, poop that flushed away got flowed back , and the toilet bowl filled with shitty water    

call the reno guy and he said he will arrange someone to help us, hope he dont bluff us ,
i see you did mention the offset flange, i doubt if they ever use that 

we didnt suka hati wanna move the toilet, the reno guy say, can ah, can move, then we planned to shift, now BIG and smelly problems occurs
