I don't recommend it. Gonna peel

Tastes change with time - and fashion promotes the latest trends so that eventually what ever you choose could look dated... It's what keeps business going - so maybe only tile where it's needed... Personally, if I were choosing for myself, I'd choose plain white in the largest tile with absolute minimum grout as I hate when the grout looks old / grubby as always happens . Then I'd add colour with towels that could be changed to give a different feel when I fancied a change if you see what I mean ! That's my taste - yours could be totally different ! There's loads of beautiful pics on Houzz - best idea is to do a bathroom search and see what appeals to you ! Then think is it practical ? Can I afford it ? Will it suit the house ! If you are doing the floor too - adding underfloor heating is a lovely way to keep an ambient temperature and- let's face it - it's kinder on bare feet too !!

If you take the wall down between the hall and front room you wont get any more furniture into it as it will still be a corridor. I say save your money here. Personally I would put a dining table in here. The back room with the stairs will make a lovely living room. I presume the upstairs is not big enough to put the bathroom up there. In the kitchen area I would put the bathroom in the sink area and then put the kitchen at the garden end so that you end up with a lighter kitchen and a bathroom with no window. Plus this way even though your kitchen will be small now you may be able to extend it later.

adding a small bathroom extension to garage. 5ft wide and 12 ft long. Wet room on the end wall, whb in the middle and toilet on the other end wall. I would like to have a slate tile on the floor and walls of the wet room section. Should I tile the entire room floor in the slate too?
