Do I need a separate WC compartment?

Optional — in compact en-suites it wastes space. In larger en-suites (8m²+) a 1,200×900mm enclosed WC compartment provides privacy when two adults use the bathroom simultaneously. Solid-core door with quiet closure; ventilation extract independent. Common in luxury master suites; valued by valuers.

Bath or shower in the master en-suite?

Both ideally in 8m²+ space — shower is daily use, bath is weekly indulgence. If only one: shower wins for adult-only households and households that already have a family bath elsewhere. Bath wins only if the master en-suite is the sole bath in the house, or the user has strong bathing preference.

How do I avoid a 'hotel bathroom' look?

Hotel-bathroom = generic shiny tile, undifferentiated brassware, no character. Avoid by: (1) introducing one warm material (timber vanity, wool rug, basket storage), (2) custom artwork or framed prints, (3) coloured grout or tile in feature zone, (4) bespoke joinery vanity instead of off-shelf, (5) authentic finishes (real marble, real brass — patina over time), not mass-market porcelain copies.
