HUGE 400 X 400 RAIN SHOWER in middle of bathroom - how to drain it...

[Coastal]

Hi all,

We are making our new bathroom which overall will have interior space or 1500 w x 3300 l.

As per the picture below the bath will be along the back wall (1500 x 760) - In my picture below the brown square in the middle represents the ceiling mounted shower head, a square rain shower 400 x 400. The black line with "drain" is the proposed drain (1500mm long, 55mm wide, 20mm deep. Drain has fall to the central outlet. outlet size 36mm, to suit 40mm puddle flange.

Questions:
1/ Do you think installing shower in ceiling at a distance of 300 from where the bath ends is far enough? not far enough?
2/ Do you think the drain should then be over the centre of the shower head ? that is 500mm from bath? and we pitch towards the drain from both sides
3/ where to pitch from and too?
4/ would a 1500mm drain with the drop and the end rather than centre be better?
5/ Any good tilers out there on the central coast?

Any advise would be gratefully appreciated -

Best regards
Coastal

no desire to rain on your parade (heh) but I think this will be a fair challenge ... so much water over such a large area will likely result in everything getting soaked. Drainage is going to be a serious issue therefore a 450 to 750 long drain will probably be necessary to ensure removal of the water. Are all the fixures in place or plumbed for those positions? Where is the door? I ask because there may be a better location for the items that enable you to enjoy your 'dream bathroom' with all the goodies you want, without drenching everything each time you bathe.

BTW I had no idea a 400mm unit was available, but I have been looking at 250 and 300 mm units, in period style meaning they're not the flat type. The biggest issue I was alerted to was that the bloody things take forever to drain so you end up thinking you haven't turned the taps off sufficiently. I imagine yours is only a couple of CMs deep so it will be a lot more practical from that perspective anyway.

In the ensuite (more like a Master-Bath) I may put a big flat one in, so I will be keen to know how yours works out. How much is it by the way?

G'day,

I've stayed in resorts with similar set ups, they seem to have a stainless grate recessed into the floor which i assume extends under the tiles a bit and is then waterproofed. The pitch to the drain always seems to be greater as well, the water does just "fall" splash a lot then drain away mostly, leaving a bit of splash everywhere, but then i've never had to worry about cleaning it up...

One place even had a melamine vanity on st/st legs about 150mm height, which copped a bit of water and was starting to look ratty. I'd go a wall mounted basin, which it looks like you show in your pic.

A pro waterproofer will be your friend with this project.

Steve,


Thanks for your response.


If you look at the drawing, across from the toilet is a pocket sliding door, that will have a interior frame, so will slide inside the wall. The sink is fully ceramic so thats why we placed it near the bath - everything waterproof there and away from the door.


The drain I have chosen is almost the exact length of the bathroom is 1500 long, 55mm wide, 20mm deep - do you think that will be enough?


Being that its a rain shower there is no pressure so im hoping it wont be too messy. It acually will sit in the ceiling whichis 2400 height. it was $350.

Godzilla,

"A pro proofer" are they separate to the tilers and plumbers? or is that the tiler?

You are exactly spot on in that its a stainless steel grate, the length 1500 being the entire width of the bathroom, I am just wondering how to pitch toward drain and if the drain should then be over the centre of the shower head ? that is 500mm from bath? and we pitch towards the drain from both sides?

any help? ideas?

Fit the drain alongside the bath and have the bathtub face recess down about a inch to the drain which needs to run the full width of the room. the shower head needs to be around 500mm from the tub, the floor pitch should start at the toilet and needs to be 1:60

Apologies for not reading your post more accurately ... I was on my tablet ... now am on 70cm screen.

Don't forget that whatever is ON your vanity will get wet too. Having lived in Malaysia, where the toilet is the shower room in some places, everything getting wet can be both a pain and dangerous. But ya get used to it .... I just don't know if I'd want to force visitors to have to worry about such things....

$350 sounds like a solid touch but I guess if it gets the result it is worth it. Doubt they'd get much cheaper around the place anyway, being so unique. Are you saying that you are mounting the head directly onto or 'into' the ceiling?

[Godzilla73]

Yep, get it properly waterproofed, one of the more experienced forum members "Oldsaltz" will be along and he'll give point you in the right direction. If you're going to this much trouble you don't want to be re doing it in 12 months time because someone slapped on some goo with a paint brush...

what stops the toilet paper from getting wet?

[juan]

I just cannot feel comfortable with an open rain shower and also have all the concerns others have mentioned.

Why not put in a dedicated shower cubicle?

I think if it was my project I would put a frame-less shower where the toilet pan is opposite the entrance door and move the toilet down next to the bath on the same side as the vanity and shower. My belief is it will be more functional than mopping up water and trying to find dry towels, toilet paper and clothing.

[Oldsaltoz]

I have to agree with Juan, you will end up with a very wet, wet area, not having a screen also means the wall floor flashings will have to be doubles for 1.5 each side of the shower on both sides of the room.

Also note, many of the trough drains being sold in Oz today do meet our waterproofing standards and are being imported and dumped onto our market; steps are under way to stop this but it will some time before it stops completely.

A simple single nib wall about a metre high then glass to 2.00m would be good, you could even include a niche in the wall/s to store your shampoo etc.

Good luck, :)

Thanks for your repsonse - I was hoping i could put the head 400 or 500 from bath and then infront of that (dont know how far) but put the drain 1500 long (full length of room) infront of the bath and shower

Why do you think alongside the bath is better?

gazza the toilet is at the other end

[heavytrevy]

Alongside the bath is the easiest way to contain the water and also keeps it away from the toilet area , its also easier to screed and tile .
If it where my wet room id waterproof all wall and floor.

Btw youre drain dosent comply with standards, it needs to have a 50mm outlet
source another.

Cheers Trev for the info - i will make sure to upgrade to a 50mm - when you say drain along bath - do you think the rainshower head which will be fit into the ceiling and is 400mm x 400mm should be 400mm away from the bath? they dont have much /any pressure so there should not be much splash also where do you guys think the level should being to change in the tiles toward the drain?

[heavytrevy]

shower head centred 550/600mm from bath face(.After looking at the room measurements :wink: ) The drain should be fitted alongside the bathface one side to the other, gradient should start at beside the toilet and be 1:60 towards the drain/waste.

Hello Gents
Thanks for ALL the advise - here is how I am looking now:

87964
-Bath = 760 wide
-Grate is 1500 x 850 x x 200 deep, fitted alongside the bathface
-Rainshower installed in ceiling is 400 x 400 and set 500 from bath
-wall hung ceramic sink is 630 w x 460 d and set at end of shower head
--sink set 33 cm from cistern
-Internal sliding/pocket door = 90
-the floor pitch should start at the toilet and needs to be 1:60 toward drain/waste

Any further advise comments?
Do you think a ceramic sink would cop lots of water from the pressureless ceiling mounted rainshower?

who should mount this? builder? plumber? me?
