# Where the budget goes: a quote for 90 m²

We broke a real finishing quote down line by line. The tiles turned out not to be the most expensive item.

A 90 m² flat in the Eixample: two bedrooms, two bathrooms, a kitchen-living room and a dressing room. Finishes and fittings only — no building work, and no furniture the client brought in themselves. Figures rounded to the hundred, shares calculated against the total.

## Four lines that eat two thirds

People arrive with a budget for tiles and leave understanding that tiles are a quarter of it.

- 01 Surfaces Porcelain for the floors, the bathroom walls and the splashback — €21,400. Plus trimming and cutting: €2,900 on a line of its own, which is the one people forget.
- 02 Bathroom fittings Taps, sanitaryware, shower systems and concealed cisterns — €18,700. Half of it went on two taps and one shower column in the master bathroom.
- 03 Doors and partitions Eight flush leaves with frames and hardware — €16,200. More than all the bathroom furniture put together.
- 04 Lighting Thirty-four downlights, four pendants and a track system in the living room — €11,500. The pendants alone were a third of the line.

Cutting and trimming are a separate line. On large formats that is up to 15% of the price of the slab.

## Where a quote usually lies

Three items almost always surface later. Delivery to a floor without a lift — from €300 to carry large-format slabs up by hand. Back boxes and boxes for flush doors: the electrician allows for them, the client buys them. And consumables — adhesive for large formats costs three times as much as the ordinary kind, and you need three times more of it.

> A quote adds up right until the day the first 3200×1600 slab turns up on site.

## The quote line by line

| Line | Amount | Share | What’s included |
| --- | --- | --- | --- |
| Surfaces | €24,300 | 27% | slabs, cutting, adhesive |
| Bathroom fittings | €18,700 | 21% | taps, sanitaryware |
| Doors | €16,200 | 18% | leaves, frames, handles |
| Lighting | €11,500 | 13% | downlights, pendants, track |

The master bathroom took 34% of the fittings line on 9% of the floor area.

## How to use this

Proportions are steadier than sums. If surfaces come to 40% of your budget and lighting to 4%, the odds are the slab was chosen above the class of the project and the lighting was never costed at all. That is not a mistake, but it is better known before the order than after.
