Cost for replacing main bath + 2 pc en-suite with 2 full bath

We are looking to buy a new house, but most houses on the market in our target area only have a 2 pc en-suites and 40-50 yrs old bathrooms.

Based on the blueprints generally the 2 pc en-suit share a wall with the main bath. If the wall between the bathroom moved, and closets that cut into the space given up, there is enough space to have 2 full bathrooms. How much that would cost us?

I know the price can vary a lot based on tile, vanity, fixture. We do not want fancy, just want 2 bathrooms. We may not even keen of having a tub, just shower.

We are in Edmonton if that matters.
