Bathroom setting out

[Paul Lewis]

Hello everyone this is my first post I'll try not to waffle.

Im in the middle of a house renovation and I'm just about to tile my bathroom.

However I have a setting out problem with regard to the height. I'm using 300x 600 tiles and 3mm grout lines.

If I set the tiles so they're almost equal cuts top and bottom of the wall the bath is positioned it leaves a 30mm slither at the bottom of the window.

If I increase the size to 100mm (see photo 3) it leaves a slither of 60mm around the top of the room (see photo 2) and a slither of 80mm above the shower tray (see photo 1)

If I lower the tile around the window further it obviously increases the slither around the top of the room but reduces the one in the shower then creates one in the bath.

Shall I stick with 100mm at the bottom of the window and accept the shower tray and top of room as these are less noticeable? Or are there any other suggestions?

Thanks in advance

Paul

Oh dear I'm an engineer haha. Is it that obvious.

I was trying to centre round the window as best I can without leaving small cuts but I think I'm going to have to compromise somewhat.

Are you over boarding the old plaster

 

[Paul Lewis]

No I was told it will be fine providing its been primed

What's going on here with the shower walls?

 

[Paul Lewis]

It's had a tanking membrane painted onto it. It will be tilled in the same tiles as the rest of the room

It was more the lumpy bumpy right hand wall or is that an optical illusion?

I would check the weight of your tiles.
600x300 porcelain tiles on skimmed plaster maybe to heavy...

We'll that's me up the creek then i told the blokes in the shop what I was tiling onto and they said nothing at all. I've installed all the plumbing and drainage so too late to overboard

I take it doesn't matter that it is skimmed on cement rather then board and its the bond strength of the plaster to the substrate which is the problem.

It's only a couple m2 that's plastered aswell the rest is boarded or cement render

That ^^^^^ is the answer.

This job gets better and better. Ever wish you never started something???

We'll overboard is out the question as I can't afford to loose the size and the plumbing has all been put in.

Returning them is out the question as I've opened loads of boxes to measure the tiles.

So my only option is try to remove the plaster from the wall to leave the cement render.

I think k I know the answer to this question but I will ask anyway. Could I drill a series of holes through the plaster into the cement?
