HELP-fair price/best way. no idea about tiling.

[alex1]

Hi.
I am shortly having a new bathroom fitted in my flat, The floor area of the bathroom is around 6 sq m, however after the bath, WC, vanity units etc I am only left with about 3 to 3.5 sq m floor area.

At the moment I have pretty cheap old greyish slate looking tiles, which I hate. They are secure and not loose.

I had a quote to retile this, for £125, over the top of existing tiles is this a fair price more importantly, tiling on top of tiles is this frowned upon, I want it to look level and have a nice finish as there is no point doing it if it looks naff.

Should I rip the old tiles up and lay marine ply ready for the tiler. Or maybe there is marine ply already under there. What do you advise, Im really not sure.

I'm based a few miles outside central London regarding prices.
Any help or advise would be great, I have quite high skirting boards and don't really want to remove them should i just run the tiles straight up to the skirting, Is the a way to finish the edges off nicely that I should ask for.

Or do you think it would be cheaper and just as good to marine ply over the old tiles and lay down a laminate look vinyl instead.
Any advice would be really really helpfull
Thanks a lot.

....or if I layed marine ply ontop of the tiles could the new tiles go on top of that, or should the old floor tiles be screeded????

Not good tiling over tiles. Height is an issue too.

They really should be removed first then depending of the substrate the floor needs to be prep'd, Ideally with a tile backerboard rather than ply but that all depends on what is underneath the current tiles

£125 is too cheap to do the job properly but it is also too expensive to bodge it up
