In choosing our new bathroom taps we actually decided to choose to get mixers, instead of individual taps. Our builder actually reckons that mixers require less maintenance, last longer and generally work better than separate taps do. Tamara and I personally think that they look better as well.
Our vanity mixer looks good and is working pretty well so far. Caleb unfortunately couldn’t reach it as first, as it is a bit high, so we got hime a new bathroom stool. Now he handles it pretty well, but it was a bit of a learning curve for him as apposed to the separate taps.
We got a similar looking mixer for the bath and shower with a built in diverted for the shower.
