What would the recommended best option for levelling this vanity unit.
It is approx 1cm out of plumb from back to front.

Use some shims to level.
Trim the bottom to fit.
Add a tapered trim to the bottom.

Ideas welcome.

Strip of something white and water resistant under front edge, e.g.
slice out of cheap plastic chopping board. And fix the unit firmly to
the wall.

(I'm assuming it's the floor sloping?)

Or as other poster said a pair of adjustable feet at the front, fitted
to the bottom shelf (but then there will be a visible gap).
