ᐅ Surcharges for Additional Effort in Tile Installation

Hello,

We finally have to deal with our least favorite trade, tiling!

Our contract with the general contractor includes tiles and installation at a size of 60 x 30 cm (24 x 12 inches) and a price of 30 €/sqm (3 €/sqft). The tiles we have now chosen cost 38 €/sqm (3.53 €/sqft), which means an extra 8 €/sqm (0.74 €/sqft) for about 50 sqm (538 sq ft). Okay, that’s fine.

But now the tiler suddenly wants 20 €/sqm (1.86 €/sqft) plus VAT, so a total of 24 €/sqm (2.23 €/sqft) extra because the tiles are longer—they are sized 90 x 22 cm (35 x 9 inches).

I find that quite excessive. I understand that there is a bit more effort involved with installing larger tiles and that he wants a little more money, but is it really 20 to 30 minutes extra work per square meter?

Could that be right? It seems quite high to me...

I am seriously considering replacing the tiles in the kitchen and pantry with parquet flooring instead...

Best regards,

Andreas

That is common. For sizes larger than 30x60 cm (12x24 inches), the installation effort is significantly higher in order to lay the large tiles evenly. With smaller formats, the tiles are simply laid and gently tapped level. This method is only partially effective for larger tiles. In these cases, much more work is needed on the substrate, adhesive, etc.

We pay about 20€ more per square meter here.

But the additional price list for the tilers is even longer:

Floor tiles and wall tiles: +XX Euro/sqm
Tiles with rectified edges: +XX Euro/sqm
....

This is also the statement from my tiler.

Up to 30x60cm (12x24 inches) he installs everything alone; beyond that, only with a second person. We have 60x120cm (24x48 inches)...

With tiles twice as large, it makes sense that it might take twice as long, since the same amount of time is needed per unit area. Waste and cutting losses are basically always irrelevant because the tiles are often supplied by the construction company, which usually includes a generous allowance for waste. Calculating for rooms with unusual shapes is naturally more complicated. I consider the pricing for installing large-format tiles to be opportunistic in terms of cost. Sure, it takes longer per tile, but you also have to install significantly fewer tiles overall. The edges are probably more challenging since much more trimming is needed with large tiles. Also, large tiles result in more edge tiles overall.

We have a 120x60cm (47x24 inches) kitchen backsplash. The tiler really groaned about that.

30x60 to 60x120 is not actually twice the size.

However, the material cost per square meter is higher because you need to use that material in the first place.

Hi,

well, for 20 € more per sqm (square meter) they must take at least 20-30 minutes longer per sqm. And I seriously doubt it’s that much.

For smaller formats, you just lay and gently tap them into place. That only works to a limited extent with large tiles. Much more effort is needed for the substrate, adhesive, etc. We are paying about 20 € more per sqm.

But the price surcharge list from the tilers is even longer:

Floor tiles and wall tiles: +XX Euro/sqm
Tiles with rectified edges: + XX Euro/sqm
....

I just checked tile adhesives for fun; the cheapest are about 0.80 € per kg (at 1-2 kg per sqm, that’s 0.8-1.6 €), and the expensive ones a bit over 2 € per kg, so max 4 € per sqm. So you can reasonably explain a 3-4 € per sqm surcharge for porcelain stoneware, but definitely not 12.5 € per sqm.

Silly question: is porcelain stoneware always rectified? I just noticed that here they only want a surcharge for rectified wall tiles. For floor tiles (which are rectified porcelain stoneware here), it seems not to matter?!

I’m curious; we’ll meet with the tile people again on Saturday. In the end, we might completely redo the tile planning…

Table with additional prices for laying porcelain stoneware tiles and edge surcharges.


Tiles are just annoying, it’s a pity you can’t lay wood flooring in the bathroom!

Best regards,
