Bathroom Refurb

[alanrob]

I am refurbing the kids bathroom. It will have a bath with a ceiling mounted power shower head and head on a hose. So I want it to be as waterproof as possible because, well you know kids...

I am replacing all the plasterboard, which was part tiled and part painted and knackered, with 12mm Orbry Insulated board (similar to marmox I think). Including fixing to the block wall which was dry lined. This will then be tanked with BAL WP1. Then tiled with 400x315 ceramic tiles.

The bath is going to go in before tiling I think. There will be a tiled shelf needed at each end of the bath as the bath is shorter than the room. I will put a baton on the wall for the bath edge and this and the shelves will be tanked too.

The floor is t+g pine which has been mostly replaced with 18mm ply.
This will be covered by 12mm Orbry board, BAL WP1, Electric UFH, SLC, and porcelain tiles.

Am I doing this right?

Should I put the SLC and ufh or the WP1 down first?

Can I put the Orbry board and SLC and WP1 under the bath too? I am am concerned about point loading from the baths feet.

Thanks

Waterproofing should go down last.
Weight of bath feet will compress the Orbry boards so don't put them under the feet.

You could skip the WP1 as a complete "after tanking" and simply tape and waterproof the joints and fasteners? Then fix your ufh and slc and tile away.

Thanks, I thought that would be the case.

I agree with the weight of bath best trick is to spread load with solid timber so weight is disributed, ps I assume your expecting floods or your in a flat for that's expense with tanking and water proofing as it's not a wet room
