Replacing a hotel tub costs roughly $3,000–$5,000 per room once you include plumbing, tile, disposal and finish carpentry — plus 3–7 days of downtime per room.
Refinishing runs $475–$875 per room and returns the room to inventory the next morning.
Across a 100-room property, that’s roughly $250,000–$400,000 in savings on a single refresh cycle.
ADR (average daily rate) can hold or increase because rooms photograph like new. Bad-bathroom reviews decline sharply.
