Watertight Bathroom Tiling

John2510 · 16 Nov 2006

Had a quote for getting my bathroom walls and floor tiled - the bathroom has a corner shower so making sure things are watertight seems important to me.

I did a little research on the net and found you can get various membranes and specialist adhesives like Ruberoid - however my builder/tiler/etc said they would simply PVA walls and floor prior to tiling.

Would this be sufficient to ensure I am watertight?

It\\\'s particularly important to me as I am in a 3rd storey flat and don\\\'t want wet neighbours

PVA will do nothing to make the job watertight and will possibly reduce the adhesion of the tiles.

Have the wall tanked with a tanking system such as BAL WP1 or Dunlop do a cheaper one.

It will cost about £60 and take an hour to apply and will ensure a watertight job.

id agree,ive recently used a bal kit to do my shower,bit expensive for what it is but you may as well do it properly first time

thanks for the advice!

It's worth getting it done right for an extra £60

Why why why why WHY do people try to ensure you they're doing a job right when in actual fact they're going to be causing you long term problems....sigh

If you have plasterboard walls you might want to consider that it may be about the same price as the kit to replace them with aquapanel.
Aquapanel would be the proper way to go if this is the case.

I bought a BAL WP1 kit, but wish i'd just ripped the plasterboard off and used aquapanel instead.
The BAL WP1 kit is there for convenience in my view.
If you want less disruption, then go for the kit or an equivalent.
Shop around though, £60 from Topps Tiles is expensive!

(You should be aware that I'm not a professional, I'm just commenting based on doing my own bathrooms at the moment)

I sometimes wonder if this whole board is run by Topps Tiles

I asked in B&Q about the waterproofing the other month and was told to use gloss paint on the wall first, before tiling, so the water wouldn't penetrate into the wall beneath the tiles.

What's worrying is that some people will take this advice...

James, the aquapanel will not stop water!

It will however not deteriorate if it comes into contact with water so it still needs to be tanked to make a watertight barrier. The tanking seals all joints and corners as well as the surface.

If I'm doing a new wall then its aquapanel and then tanked.

So will the boards let water all the way through?

Jasonb · 21 Nov 2006

Yes and especially in corners and where two sheets butt up against each other. Just try wetting a bit of AP and watch the water soak in.
