Moving a toilet: what the soil pipe really involves
The prettiest layout in the world fails if the toilet waste cannot fall towards the stack. In a terrace the stack is often in a corner you did not choose. Good design starts there.
Small move
Sliding the pan along the same wall, within the reach of the existing branch, is everyday work. The new pan might be close-coupled instead of low-level. The floor stays largely intact.
Moving it properly
Crossing the room means a new 110mm run with fall, supports, and a way back to the stack that does not create a trap you cannot clear. Boxing-in is part of the finish, not an apology. If that cost buys you nothing but a different view of the same small room, we will say so.

Quick answers
Can any toilet be moved?+
Only if the new position can connect to the soil stack with a legal fall and a route through the floor or a boxed wall. Side waste into a neighbour’s flue is not a plan.
Is it expensive?+
A small shift beside the existing stack is often modest. A move to the other side of the room is a different job: floors up, new pipe, boxing, and making good. It should be its own line on the quote.
Will you macerate a toilet to avoid the stack?+
We would rather design around a proper soil connection. Macerators have a place in some basements and distant ensuites, and they also have a reputation for being called out. We will say if we think one is a bad idea.
