Hi Jo, If you are ever in the market again for Black door handles, we can definitely help Here is a video of some of our selection https://www.avantgardehardware.com.au/black-door-handles/

Invest in a custom made one from your local glass and glazing specialists - it'll be made to fit the vanity top exactly and the edges of the mirror should also be sealed to prevent corrosion. (which often happens to mirrors from the hardware stores)

Hi, Mau, another option that we actually use is to purchase all the fittings and then make the ladder to the exact size you want. Try googling "Library Ladder Hardware" for a supplier close to you. It is also always good to get the type of wheel that locks when you stand on the ladder. Hope this helps, Malcolm.
