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

Are all of them the same size....

 

[Paul Lewis]

Surely there can't be that much variation in size or it would be impossible to to get straight grout lines?

Also I don't have to measure every tile do I?

There can be a considerable difference in tile size. +/- 2mm is not unusual so if you have one that's 2mm bigger and one 2mm smaller, well you get the idea!
Open random boxes and check a few, you should do it anyway especially if you're trying to preplan to the mm.

I'll have a look when im home later. It's turning into a bit of a mare haha.

So what are the general rules for setting out?

General rules about setting out? Don't let an engineer do it!!

You normally aim for whatever is aesthetically pleasing, be it centering a window or wall to allow even cuts. There's usually going to be a compromise somewhere though so generally you try to put that where it's less visible, behind the door for example.

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
