Carrerahill Posted July 4, 2022 Share Posted July 4, 2022 I am going to form a slightly raised shower area in the bathroom. I found a system by Schluter which is the membrane and waterproofing joints and tapes etc. Has anyone done this recently and can they give their advise and thoughts on it all, systems and products used please?

Thorfun Posted July 4, 2022 Share Posted July 4, 2022 Following with interest as this is something we might need to do as our floor joist are so close together finding a shower tray with out to fit might be hard!! Link to comment Share on other sites More sharing options...

At present I am thinking of using the Schluter system, they do a kerb, then I was going to do it the old fashioned way and use a dry pack mortar to make the base, then Schluter membrane and joint tapes etc. That is the plan for now, we will see how that pans out once others comment on options and experiences. 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted July 4, 2022 Share Posted July 4, 2022 Have done a curb previously, which was basically a row of bricks, then screed inside to the required fall, then waterproof system on top and over the curb. Link to comment Share on other sites More sharing options...

I am on a suspended timber floor, but I did see someone simply use some wood... bricks would work well if I was on concrete. I think it would just need to be solid and without flex so the tiling doesn't crack. Link to comment Share on other sites More sharing options...

Xps high density foam, or get a sheet of marmot board and cut up, or buy the shulter curb. 1 Link to comment Share on other sites More sharing options...
nod Posted July 4, 2022 Share Posted July 4, 2022 I’ve used Impey over the last few years Never any issues Probably the stickiest membrane I’ve used 1 Link to comment Share on other sites More sharing options...

I cannot actually find the kerb on sale anywhere - yet. I like the idea of cutting strips of the board. Edited July 4, 2022 by Carrerahill Link to comment Share on other sites More sharing options...
Thorfun Posted July 4, 2022 Share Posted July 4, 2022 so I've watched some videos on the Schluter system using Kerdi board and shower tray and curb etc and it all looks pretty cool. but, I'm not sure that's exactly what I'm after. I don't really want a curb to step in to our shower rather I'd like a wet room type affair albeit I might need to step up in to the wet room area. so I was thinking of building a false floor about 100mm up from the existing floor and then putting some form of waterproofing system and preformed wet room shower tray on top of that which should give me space underneath to be able to route the waste pipe to between a joist! I feel a lot of research coming my way as I've only just started thinking of this and the plumber is due to start first fix in a month so I need to get cracking! still following this subject with interest though as it's already sent me down a few research rabbit holes. 😉 Link to comment Share on other sites More sharing options...

I believe this will work but I need to do more research on the whole system and it's depths and sizes etc. I will also speak to the plumber about it all and get his take on it.

ProDave Posted July 5, 2022 Share Posted July 5, 2022 The Impey wet room shower former that I used has the waste offset in a central circular section that could be rotated, so as you rotated it, the off centre waste position changed. You would be very unlucky indeed if you could not find a position with that where the waste did not line up with one of your gaps. And if it was only slightly off, move the whole tray over slightly and fill in the gap. https://www.impeyshowers.com/Wetroom-floor-formers/Aqua-Dec-EasyFit-Wetroom-Floor-Former/ 2 Link to comment Share on other sites More sharing options...
Russell griffiths Posted July 5, 2022 Share Posted July 5, 2022 Instead of fitting a pre formed tray and filling in the edges, why not buy a tray former that is too big and trim it down to get the waste where you need it. 2 Link to comment Share on other sites More sharing options...
Thorfun Posted July 5, 2022 Share Posted July 5, 2022 both great ideas and avenues for research @ProDave and @Russell griffiths. and sorry @Carrerahill I seem to have inadvertently hijacked your thread! Link to comment Share on other sites More sharing options...

I don't mind, we will all learn! I just want to have all the stuff in stock so I can go in all guns blazing some Saturday and get it done pronto. To clarify my kerb requirement, I don't want a kerb as in step as such, what I want to create is a little raised bit - I think 50mm would work but that is more a trip hazard, so I think I must go 75mm to make it a big enough step not to be a trip hazard, I also want the raised space to create a services zone below, and I am slightly afraid of level showers in case of floods, I feel this will also enable me to create a floodzone that could take 20-30 litres in the event of a drainage issue. Maybe I am just creating a potential disaster but I think plenty of people have walk-in showers on the first floor. Link to comment Share on other sites More sharing options...
