Need help changing a bathroom drain plug in a rental

I'm renting a house in Ireland and need a reliable handyman to replace a worn-out bathroom drain plug. The current plug is loose and sometimes leaks, and I’d like a proper, secure fit with a quick, tidy finish. This job involves removing the existing plug, inspecting the drain setup, selecting a compatible replacement, and ensuring no leaks after installation. I’d prefer someone with experience in bathroom plumbing basics and the ability to test the seal. If possible, please include a quick ETA for when you could come and what materials you’d need from me. Thanks!
