How to install Villaboard for bathroom shower reno?

[Danne]

Hi all.

I just starting on a shower Reno, installing larger shower base, re-doing walls (going from wall liner to tiles) using a Wet Area Solutions solid surface shower base. I'm sure I will quite a few questions as I work through however first one is around the wall cladding. At the moment the walls are Aquachek, I'm wanting to change the shower area to Villaboard. First problems was Villaboard is 6mm or 9mm and Aquachek is 10mm so joining will require packers on the studs. As I am working within a 1m x 1m shower base (it's a corner shower so 2 walls to do) should the Villaboard be installed Horizontally or Vertically? Second question is how do I join the Villaboard to the exciting Aquachek (taping etc) and should the water proofing extend over that join?

That's a lot to ask..

Thank you 

Danny

Hi @Danne,

If you needed to add screed to support the shower base, then it should say so in the installation instructions. If it is the one I looked at, then it doesn't appear to need it, but I would confirm this with the supplier to ensure it is installed correctly.

Let me know if there is anything else I can assist with, and keep us updated as your project progresses.

Hi @MitchellMc, different question for the same topic. I'm putting Villaboards on the bathroom wall... is there any concerns if I want to use different sheet sizes (but same thickness 6mm)  for different wall within the bathroom? i.e.: 2 walls will use the 1800x1200 sheets and the other 2 walls will use the 2700 x 1200mm. (this is to reduce the number of cuts and joints)

Is there any reason why I should keep the same length/width on sheets in every wall?

Thanks,

Martin

That’s absolutely fine @MartinM, and in fact it’s generally considered best practice.

There’s no requirement to use the same sheet length on every wall, as long as the sheets are the same thickness and are installed in accordance with the manufacturer’s fixing and jointing requirements. Using larger sheets where possible to minimise cuts and joints is actually a good approach, as fewer joints mean less potential for movement, cracking and waterproofing risk in a bathroom.

As long as each wall is framed and sheeted correctly, the edges are supported, and all joints are treated appropriately, mixing 1800 × 1200 mm and 2700 × 1200 mm Villaboard sheets within the same bathroom is not an issue at all. It won’t affect performance, waterproofing or compliance.

So yes, it sounds like you’re on the right track and thinking about it the right way.

Please let me know if you have any questions.
