Shower seat with ufh

[Geoff Thacker]

Hi everybody, Iv been a member for 3-4 years now but more of a watcher than a contributor. Now I need a bit of advise so apologies, I’m about to start a large bathroom with a walk in shower, I’ll be doing this with sheeting the walls with backer board and fully tanking the full room as I always do, advise from you would be grateful when it comes to the UFH the client has purchased enough for the seat that’s being fitted in the shower/steam room (it’s a backer board type with the rounded edges and back) it’s then being tiled with mosaics, I would like to screed over the uhf on the seat to give me a better surface to fit the mosaic what product would you advise. This is the first time in 20 odd years Iv been asked to tile on of these seat with UFH and would just like to hear your methods.... many thanks Geoff

Firstly when you say got enough ufh to do the seat is that going to be part of a larger cable / Matt system as I think you will find the ufh companies don't changing planes with their product, ie running ufh on the floor then up a wall , they would recommend 2 separate mats for this , I presume this is because of movement between 2 different surfaces could stress the cable, Secondly you are not doing that without skimming it over as otherwise you're trying to put mosaics on an uneven surface , absolute recipe for disaster , I would skim it a few times with rapid set until I was happy I had a nice smooth surface

Apologies for not explaining myself correctly (that’s why I don’t post much) There will be two mats supplied by prowarm one for seat and one for the floor.. my main question in the original post should have just said what would you use to scrim/screed over the seat once the mat had been fitted as Iv never fitted a mat on anything apart from a floor? thanks for your replies on using rapid as that’s what I was thinking but wasn’t sure if that could cause it’s own problems.... thanks G

I would use a loose wire ufh and screed over with rapid set.
