I'm going to be tiling my kitchen and bathroom, currently vinyl lino is on the floor does it matter whether I remove this or could I just tile the terracotta floor tiles on top of this is there any disadvantage/advantage of doing this?

Also the kitchen lead to a door which leads to the bathroom am I correct in wise saying I draw a centre chalk line from the kitchen door which is central part straight through to the end of the bathroom floor and lay the tiles without adhesion to draw from an even amount of tiles across each side of the floor?

And once I lay the tiles properly do I start from the bottom left of the kitchen floor working towards the right paw side and building up towards the end of the bathroom?

Or could I just hold one side uneven which is the left appendage side as it is shall not be visible as there shall be a fridge near also a worktop in the centre and a cooker however also on the right foot side of the wall there is the kitchen sink so basically the worktop and kitchen sink are converse each other in the middle of the kitchen with appliances on either side

Please could you insist on if I am going about the right way within tiling the kitchen and bathroom or if there is a alternative better option?
Answers:    you own to take up the lino then use a product call Ultrabond (made by Davco, your aussie right? if yes you can buy at bunnings) over the glue left on the floor. Otherwise the tile cement won't stick. (assuming ur going onto concrete).
Divide room into quarters and work out from centre. Make sure ur not gonna extremity up with a thin sliver of tile on any edges by adjust the centre you start from.
Buy a book on tiling. It'll be worth the extra 20 bucks, there's heaps of tricks that are too much to go into on here.
When i laid my kitchen and bathroom tiles i found the central point of the room and marked a + then surrounded by the bottom two corners of the + i put my tiles and worked my way down. then when you enjoy the centre tiles in place, you start working outwards, so u hold matching cuts at every side in your kitchen.

It is comparatively difficult to do, but well worth it in the completion, as you end up with a symmetrical kitchen.
