Toilet Move + Tile over base for wet room...

DublinDilbert

Looking for a little bit of advice on suppliers and options. Basically an elderly relative needs a down stairs shower/wet room has been let down by two different people who were supposed to come and do it.

The power shower and water supply is sorted so no issues there, as it will just be relocating a power shower from the bathroom up-stairs and bringing the water feed down.

The toilet in the downstairs room will need to move 1m or so to the right along an external wall. The soil pipe is currently going down into the slab then into the drain out side. I'm wondering would it just be best do core drill the wall and run a new pipe to outside and drop it down into the same sewer (which runs along side the house) rather than taking up 1m of the floor to run the waste pipe inside the house. If that's not feasible I can just take up a 1m run of the floor and bring the soil pipe over to the new location (with correct fall). I would then probably run the shower waste out separately beside the hand basin waste pipe.

The shower tray will be located close to where the existing toilet is. If i bring the new waste pipe out trough the external wall, I can use the existing 4" toilet soil pipe for the shower waste. I'm looking for recommendations for a 1x1m shower based former (sit in a base of sand and cement) which could be tiled over? Who would supply these shower bases with the drain etc?

Assuming you have the room in height terms, I would dig up floor and drop in the new pipe to go and drop into the existing drop.
Unless you want to go wall hung and then u go through wall

Two 90 degree wavin bends will take up a bit of height.

Re the shower, I take it that the WHB waste goes straight down as well?

I think it always safer to have a air break between the trap on the WHB and shower, which need two separate pipes
How much of a drop is there between FFL in bathroom and path level out side?

Rather than a shower tray, why not go wet room with no shower door

Thanks for getting back to me. Yes I was thinking that, believe I would have room for the two 90 degree bends and still be able to repair the floor screed above the new section of pipe. As far as I know the slab is insulated so I assume the main sewer is down a good bit to allow for the insulation.

The hand basin waste goes straight out through the wall on its own and goes into a drain. I would need to check the levels, but definitely wouldn't be opposed to running another small waste pipe from the shower straight out and into the same shore. Keep things nice and simple, nothing to go wrong either.

I wasn't looking for a shower tray as such, I was looking for one of the pre-formed bases (say 1m x 1m) which I could cement in place, this would have all of the falls correct. I might sink the outer edge down a little and slope some of the floor into it also, ready for tiling.

Or somehing like this http://www.ebay.co.uk/bhp/mcalpine-shower-trap
You take out the 1 meter sq floor that there already,fit and plumb gully and set height,new mortar/concrete is then used to reshape falls for shower etc

Good thinking on the shower waste.
I agree that augusta's kit is cheaper: I prefer the other one as it makes the tiling a little less complex, especially in a corner, and just gives one slope for wheel chairs or other support aids to negotiate.
Single glass pane on one side and you drive in and reverse out:)

Just think about what additional rigs ur elderly aunt might require: eg fixed folding seat, decent grab rails, call buttons...

The gully calahonda recommended is class,pity they are so expensive,if you have room to make the shower area 1000 x 1200 or 1000 x 1300 it would be a way better shower, just a glass panel on one side

Does anyone know where would sell this sort of kit (or similar)?

Yes expensive, I just showed that one as an idea, you would buy a lot of driveway gully for that price

There are different ones with the outlet at one end so in an external corner they work well, straight out the wall.

Wetrooms are easy enough to do down stairs but a lot of the installers change arm and a leg, with expensive tiles and fittings: 10k is, as Tom Jones would say, not unusual!!

OP: look here at the images for ideas http://www.wetroommaterials.co.uk/
The website says trade only and no show rooms but the trade only bit can be circumvented

tub and tiles do it i think,very expensive too,It most CERTAINLY is not something you need!,you have a concrete floor.Its as simple as setting your gully at the required height for the falls required,and make shower tray with sand and cement,you can then float it with a floating trowel as good as the marmox board.Leave it dry and then put on tanking kit

thanks guys, Its just something i've never done before so was looking for an off the shelf solution which would get all the levels correct. If i'm mixing up sand and cement for to set the other tray into, it wouldn't be much more work to float it.

On the mc-alpine drain you showed earlier, I assume the white plastic bit just get set at the correct level and cemented in place then everything runs into it. The waste pipe gets cemented in place too as your creating the fall into it.

There is alot of different types of gullys.Best call to your local plumbing merchants and see what they have.I would worry too much about the white plastic bit in the picture i showed you.
If tiling the rest of the floor and putting mosaics in shower,
what i would do,
set the top of gully down 5/8 inch from floor level
connect waste pipe
set the base of gully in mortar
square top of gully to the two walls
leave mortar set for a day or two [why..,its had to put in a mortar base when the gully is moving]

a day or two later
scribe a line around the two walls the same height as floor [this is the finish height of base
the finish height of mortar base below the gully is the tile thickness plus 1 or 2 mm.
install the 3 inch mortar base to the heights you have set,use a dry mix,pack down well,the final finish is got using a trowel float

Look at impey level deck
Neptune floor formers
They are both company's that make the inset type shower tray with preformed falls in tray.
I get them through DPL
