If you have unusually shaped taps - for example, one with a flow adjuster or one that extends - then you will need to source your own tap connector. I only carry tap connectors for "bog standard" taps.
You may also choose to get a large floor covering to protect against water splashes. I would suggest waterproof tablecloth off the roll from somewhere like Dunelm, placed upside down. Dustsheets are another option, but shower curtains are not ideal as they are often only water-resistent, not completely water-proof.
I am working on a Deluxe package which will include everything you may need except for towels.
