Bathroom Vanity Cost Calculator
Prices a vanity, where whether the existing plumbing lines up decides the job.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Hours times crew times rate, plus materials and the call-out. Swapping a vanity for one of similar size with the plumbing in the same place is a short job: disconnect, remove, set the new unit, connect the waste and supplies, fit the top and tap. The cost grows when the new unit's internal layout does not suit the existing rough-in, because a wall-hung vanity or one with drawers where the trap sits needs the supplies and waste moved, which means opening the wall.
What moves the number
- Whether the existing rough-in positions suit the new vanity's layout.
- Floor-standing against wall-hung, since wall-hung needs blocking and often relocated plumbing.
- Whether the top, basin and tap are included or separate.
- Wall and floor condition behind and under the old unit, which is often damaged.
Where this one goes wrong
Wall-hung vanities need solid backing in the wall to carry the load, and that means opening the wall to add blocking unless it happens to be there. Clients choosing a floating vanity for its appearance are choosing wall work they may not expect, and the plumbing usually has to move up into the wall as well so it is concealed. The other thing to check before quoting is what is behind and under the existing unit: a vanity that has had a slow leak frequently hides water damage to the floor and the wall, and that is a named variation rather than a surprise to absorb.
Before you quote
- Compare the new vanity's internal layout against the existing rough-in.
- Allow for blocking and concealed plumbing on a wall-hung unit.
- Check for water damage behind and under the old vanity before quoting.

Questions
About this calculator
Will a new vanity fit my existing plumbing?
Often, if it is a similar size and floor-standing, since the supplies and waste come through the back wall or floor into the cabinet. A vanity with drawers where the trap sits, or a wall-hung unit, frequently needs the plumbing relocated, which means opening the wall.
Why are wall-hung vanities more work?
Because they need solid blocking inside the wall to carry the weight, and the plumbing usually has to be moved up into the wall to stay concealed. Both mean opening and repairing the wall. The look is popular and it is a bigger job than swapping a floor-standing unit.
What is often found behind an old vanity?
Water damage. Slow leaks at the trap or supply connections are common and the damage is hidden by the cabinet, so rotten flooring and damaged drywall turn up when the unit comes out. Naming it as a variation in the quote is better than absorbing it.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 160 h |
| People needed | 1 |
| Labour rate charged | $88 |
| Parts and materials | $11,000 |
| Call-out or diagnostic fee | $95 |

What comes out
| Result | Value |
|---|---|
| Estimated total main result | $25,175 |
| Labour | $14,080 |
| Before tax | $25,175 |
| Sales tax | $0 |
About $25,175: $14,080 of labour, $11,000 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $44 | $18,135 |
| $66 | $21,655 |
| $88 example above | $25,175 |
| $132 | $32,215 |
| $176 | $39,255 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
