Vanity units come in a variety of styles and sizes. If you’re renovating a bathroom you might find it cheaper to place the vanity near the existing waste outlet for the basin. This could save you additional plumbing costs.
Many vanities come with a special acrylic coating to protect against splashing, but you should avoid placing the vanity in an area where regular or consistent exposure to water will occur i.e next to the bath where toddlers may splash.
Vanities come in single or double bowl styles and you should stipulate whether you require one tap hole (if you are using a basin mixer tap) or three tap holes (for the traditional hot and cold water tap with spout in the middle).
