Fitting shower base

[Simon]

Hi,

Bought a house last year in need of decorating and been busy decorating the rooms including learning how to plaster and fitting new rads etc, so not scared of plumbing. My next project is in the bathroom which involves moving everything into a better place (cast iron bath is currently in the middle of the room) and installing a shower.

A mate of my dad's is coming next week to help and everything should be ok, i just have a small question about the shower base fitting.

This is the shower base and it will be placed into the corner once the toilet is moved. The problem is the skirting

Once I remove the skirting I plan to fit the base under the floor at the edges slightly and then tank the shower with a maepai tanking kit. The iussue I for see is the gap between the bottom of the wall and the top of the base. Any ideas on how to fill this? The wall is L+P

This is the underside of the base, it didnt come with feet and was planning to mortar it into position onto 18mm Marine ply (replacing the floorboards). One option could be to raise the base I guess?

Many thanks in advance
Simon

Exactly that thanks - was hoping for a reply from you.

Shower drain will be about 800mm from soil stack so should be fine for drop. Ill get the boards off tomorrow and start building up the adhesive layers in advance.

Thanks.

 

[Simon]

Yeah will be recessing slightly to help make tanking it easier. I will be tiling with 600x300 tiles. Any recommendations on adhesive. I usually go for branded stuff on things like adhesives, pastes etc

 

[Simon]

Cool thanks. The tiles are 8mm thick and weigh 3.8kg each so 5.55x is 21kg/m^2.

Will this be ok for the BAL flexible adhesive? Will be bonding direct to the tanking in the shower but in the rest of the room it will be half height on L&P which has had the paint scraped off.

 

[Simon]

I cant believe how many options there are for tile adhesives.

What about the BAL APD primer?

 

[Simon]

Hmm big gaps to fill plus the studwork for the wall

 

[Simon]

There is 25mm of plaster on wall. Could I just add a strip of 18mm ply im using on floor, leaving a gap for the tray to slide into. I would fill the 7mm depth difference with adhesive before taking and then tiling?

Just checked it and the stud you can see has a skirting spacer on

Adding the hardy would be ideal but there is a door on same wall so would have to do the whole wall really to avoid different heights.

Mapei Primer G any good for L+P walls for the the rest of the room?

Ok so I'm going to go for ADESILEX P10. Seems none of the 'sheds' stock it though including screwfix.

Keraquick or Keraflex looks my second option

 

[Simon]

OK so I've had a delay on this but should start today. It seems that tiling onto L+P is a bad idea and I should pull it down and completely board (maccapacca also is in this place I think).

So looks like a bigger job but one that is done right I guess

Thanks for the help - will let you know how it goes

 

[Simon]

In the end I pulled it all down and ordered 20 20mm marmox boards to board three of the walls. two walls are outside walls so should help keep the room warmer. The stud wall was 20mm deep so wanted to make it easier to line up with the door frame.

Re did the stud as one was warped, adding noggins for the shower frame. Room wasn't 100% square so the board on the brick wall go onto the shower, stud wall butts up to the base. Then used silicon to seal the gaps. I have a mapei tanking kit to fully waterproof it.

As it is now, wiring and feed for electric shower. 'Plural of dab'(avoiding the competitor filter) of adhesive are in position behind the wall for the shower and rail fittings so hope to have no issues fitting. I used to dot and dab method as the wall wasn't completely true.

Today ill be boarding the rest of the room -hopefully the window area will be ok. Give me chance to use a smaller window trim too

Progress. Been travelling a lot with work so been very slow

Tanked with Mapei tanking kit

Tiles. Added the mosaics due to a tile shortage. Pleased with them as also put over bath

Shower frame fitted

So finally got there. All walls are marmox 20mm

then I've tiled or plastered them. The plastering is ok but quite difficult on cement boards as I didn't want too thick a layer. The white finishing skim is repairs I've had to make but will look fine once sanded and painted.

The shower is a Mira 10kw and works very well.

Next job is getting a new ceiling and 3mm boarding the floor and finishing

 

[Simon]

Sorry. It's only over boarding 3mm panels for a vinyl floor cover. Joists aren't thick enough for tiles.

Flappy things is lathe and plaster . It's an internal wall so that's the backside of a plastered wall. The stud was screwed to existing stud simply to support the edges of the marmox. The marmox also will act as a great insulator as the other 2 walls are external. (Strangely they are cavity walls on a 1902 build )

Drilling /nibbling the mosaics around taps is on the to do list. There is chrome trim but I plan to do it like you have said. I have Mapei grey sealant to match the grout so should look neat.

Electric shower was alternative to a gravity feed pump. The boiler is 6 years old so didn't want to change it. I know its not for everyone but it works well and never have to worry about hot water.
