Hello everyone,
The tiler (appointed by the developer) has given me quotes for the bathroom and guest toilet. The developer specifies a standard tile price of €25/sqm (approx. $28/sqft) for tiles up to 30x60 cm (12x24 inches), with shower walls tiled up to the ceiling.
The tiler and I agreed on a 90x90 cm (36x36 inches) tile for €60 (approx. $67), installed up to 1.20 m (4 ft). The bathroom is 7 sqm (75 sqft) with 28 sqm (301 sqft) of tiles needed, the guest toilet is 2 sqm (22 sqft) with 12 sqm (129 sqft) of tiles needed.
Additional cost just for the 7 sqm bathroom – €4,200 (approx. $4,700):
€1,680 (approx. $1,880) – floor tiles including cutting waste/reserve supplied and installed
€1,400 (approx. $1,570) – surcharge for installing floor tiles on walls including extra effort due to large format and different tile adhesive
€1,120 (approx. $1,250) – aluminum profile angles for the “baseboards” that are 1.20 m (4 ft) high on 2 walls, including miter cuts
The €1,680 (approx. $1,880) corresponds exactly to the €60 tile price for 28 sqm.
-> In my opinion, the standard €25/sqm, which should be included, has not been deducted here. The additional installation cost is already listed under the next item.
-> What do you think?
The €1,400 (approx. $1,570) surcharge for large format tiles would mean an extra €50/sqm (approx. $5/sqft) – is that reasonable or still within your expectations?
The €1,120 (approx. $1,250) for aluminum profiles for just a few meters seems absolutely excessive to me. Normally, PVC profiles are installed as standard, and these aluminum profiles don’t look like they require a 45-degree bevel on two adjoining tiles. On the internet, such aluminum profiles cost about €15/m (approx. $16/yard). Aluminum profiles without miter cuts are quoted at €580 (approx. $650), which I still find quite high. Considering how quickly several tiles can be miter cut, how unrealistically high would the hourly labor rate be?
What do you think would be a fair price for 60x60 cm (24x24 inches) tiles instead of 90x90 cm (36x36 inches)? That might still be a cost-saving option. Would the extra installation cost then drop to about €25/sqm (approx. $2.50/sqft)?
For the small guest toilet, the extra cost is even €70/sqm (approx. $7/sqft) instead of €50, which also seems odd to me.
The quote even includes extra effort charges for the standard tiles, which is definitely a mistake. So I wonder if there might be general calculation errors in the other items as well.
What are your thoughts?
Thanks!

I don’t quite understand the aluminum strips and miter cuts; I always thought it was an either-or situation?
Or does it mean miter joints everywhere except at the baseboard – where there’s an aluminum strip?
GD I was also puzzled by that. But I almost suspect they really want to miter the profiles at the corners. Other people use those extremely overpriced corner pieces that allow two aluminum profiles to butt together (or the corner piece itself) without a miter cut.
I would also question using floor tiles on the walls again. Nowadays, even in specialized suppliers, wall and floor tiles are usually distinct products. I have not seen such a strict separation in three dedicated tile specialists or retailers, nor in any hardware store. At most, I have seen wall tiles only, but rarely floor tiles alone. Are the chosen tiles really classified as floor tiles according to the catalog? Only then does the extra effort (and different construction adhesive) make sense. Dedicated floor tiles are typically non-porous and require special mortar or adhesive to properly bond on walls.
Otherwise, these are typical developer markups.
When I bought a condominium from a developer back in 2015, I had to pay almost $8,000 (gross price was even higher) for an additional walk-in shower measuring 0.9 x 0.9 x 2 meters (3 ft x 3 ft x 6.5 ft).
