Are you wanting to only replace the shower or re-design the entire bathroom? To replace the shower, the toilet and radiator are too close to appreciate having a walk-in shower without the floor getting very wet. If you don't mind the radiator getting wet, then you could potentially replace the shower tray with a rectangle one and have a wet shower panel on the side where the toilet is and walk in from the radiator side. However, a plumber will be able to determine the extent of the work to make it possible.
You have another radiator next to toilet? Is it possible to remove the towel radiator? and add electric underfloor heating if the other radiator doesn't give off enough heat?
