Change bathtub drain/flange without access under bath

[Adamb97912]

Hi was wondering if it was possible to change my bath drain as it has gone a little rusty but i don't have any access under the bath as the side of the bath is tiled in.
It looks as if it would just unscrew an pull out but im worried about it disturbing the rest of the drain and ending up being a big job.

Thanks Adam

in theory yes you could but theres a few things that could go wrong eg pipe dropping so you loose the plastic bit on the underside

something could snap or the screw might break / not come out etc

tbh if it was me and you havent access i would leave alone, on another point you should have access so maybe a though for the feature
