How much tile and adhesive is needed for this?

[snowjim]

Hello,

We are planning to tile a corner in a small toilet.

Wall 1: 110x66 cm = 0.726 / m2
Wall 2: 110x50 cm = 0.55 / m2
----------------------------------------------------
Total 1.276 m2

We are considering a grout of 0.5 cm which is not included above, so with grout, it will be 110x66.5 and 110x51.

The tiles are 10x20 cm and we have 2 packages left from before with 0.8 m2 / box.

I assume you account for some waste too, so how does this look? Will it be enough or should I buy other tiles?

Sounds like there are 40 tiles per package? That should be enough to tile 44+33 tiles with horizontal orientation of the tiles, but you must do it right all the time.

That's correct, 40 tiles per box.

So, if you calculate it, it looks like this:

Wall 1: 3x20 cm + 1x10 cm (adjusting to a half tile) = 11 rows X 4 1/2 = 49.5 tiles
Wall 2: 2x20 cm + 1x10 cm = 11 rows X 3 1/2 = 38.5 tiles
--------------------------------------------------------------------------------------------------------------------------
A total of 88 tiles, which means that 2 boxes are not enough.

Wall 2: 2x20 cm + 1x10 cm = 11 rows x 3 1/2 = 38.5 tiles
--------------------------------------------------------------------------------------------------------------------------
Total 88 tiles, which means that 2 boxes are not enough.

There's a mistake in the calculation there:
Wall 1: 11 rows x 3.5 (not 4.5)
Wall 2: 11 rows x 2.5 (not 3.5)

Thanks for the correction! :

Wall 1: 11 rows x 3.5 columns = 38.5
Wall 2: 11 rows x 2.5 columns = 27.5
--------------------------------------------------------
Total : 66

So then it will be 80 - 66 = 14 tiles left over, that should be enough even if some are done wrong.

I usually account for 10-15% waste, so you have a safety margin
