And what type of adhesive are you recommending with 6mm backerboard ?Tile the floor first and put the WC on top
If the floor is good you can use 6mm baker board.
Pre mixed adhesive is not suitable for those particular tiles. You need to use a powdered adhesive that is sutable for porcelain, also a flexible grout. There are many different brands to choose from but you won't go wrong if you choose BAL Single Part Flexible adhesives or the rapid set equivalent if you have some tiling skills. prices can vary widely depending on where you are and if you have independant retailers near you. For BAL SPF expect to pay around £30-35 retail I would imagine.I'm going to tile my bathroom (walls & floor) shortly with porcelain tile which are roughly 60cm x 30cm. The walls are plasterboard and the floor is wooden, which I will cover with 18mm board.
From what i've read on here i'd be far better buying bags of powder adhesive and mix myself rather that pre-mixed tubs. I've only ever used ceramic tiles before and have used pre-mixed but think bags would be better for this job, does that sound right? if so, can anyone recommend what brand/type to buy and roughly how much to expect to pay?
thanks in advance

If you are using BAL cement based adhesive, then yes you do. Some adhesive manufacturers say it is not necessary but in any case it would not hurt to do so. priming gives you protection from the possibility of Ettringite Crystalisation forming as the gypsum of the plasterboard can react with the chemicals in the cement based addy.Hi,
Doing exactly the same job as Russell, do i have to prime the plasterboard? think yes but would like to know for sure.
thanks
