"it should be 150mm for centre of hot and cold outlets as the tap mixer or shower mixer on the market are almost all made in this size..
for basin, it is up to you. but you could keep them at leat 100mm away in order to do the installation or maintenance job easier."

"Bath: usually 180 mm centres for standard deck-mounted bath taps or bath mixer, but check the tap.
Basin: often around 200 mm centres for two separate taps, but can vary. For mixer taps with flexi tails, the pipe centres are not critical; keep the supplies accessible and within reach, commonly 150–200 mm apart.
Best practice is to measure the actual tap or sanitaryware before first fixing. Do not tile or box in pipework based only on a “standard” measurement unless the tap or basin specification has been confirmed."
