Realistic costs for bathroom renovation in an old building

hello

who can tell me roughly how much it costs to renovate an old bathroom in an old building (built 65)?

the old bathroom would have to be removed and a new one installed.

we would like a walk-in shower and a whirlpool bath. tiled up to the ceiling. the price should be medium quality (so not a cheap bathroom, but also not top quality).

we are considering buying an old house. however, quite a bit would need to be done there (including a new bathroom).

now we want to roughly estimate the costs. everything would be done by professional companies.

best regards

My parents paid about €10,000 to €15,000 - without a whirlpool tub, but with a new wall between the shower and the sink. The room is about 9 sqm in size.

However, they did not give me the prices that precisely.

oh yes, the bathroom is 8sqm. almost forgot. ;)
