Going to have problems with the drainage at some stage with the flexible pipe fitted as it is running down then up which will silt up. Very lazy plumbing.
Stripped. Replasterboarded (moisture resistant preferably) pipework sorted so plasterboaed is touching floor. Tanked retiled with trim on outside edge. Then fit door.. If its not done like this no way will it stay leak free. 👍 Just my opinion btw.
