Oh dear, thats what I thought, Honky tonk - I mistakenly ordered bath taps instead of basin taps, and even though they will still look great on the basin, I guessed the pipework may not match.
As long as the taps can fit in the basin tapholes. It could work. You'd just need to change the 15mm tap connectors to 22m.
Basins vary, but I doubt if they would fit.
