Bathroom Floor with 330 mm tiles

[juan]

Michael sorry for all the silly questions but tiling is a mystery to me.

Does the inverted pyramid work out ok with a shower like the one I have planned with a set down area about 1125mm x 875mm ?

Sorry Juan, the method only works in a square cubicle. That will be a tough one with big tiles.

Cheers

Hi Juan - heh heh ! yep now it gets complicated - you really need to know what tiles you are using, what exact shower screen size you want, and then be able to lay them out on site to locate exactly where the waste go.

It might be worth putting the plumber back while you work all this out or at least maybe get him to do other stuff on his visit.

I would be inclined to go with a tilted up border all around with maybe just a very slight slope to the floor waste 5mm and to set the entire shower area floor level but 20 mm lower than the rest of the bathroom. That way the shower waste can go anywhere.

The floor waste needs calculating by laying out tiles - but you could put it roughly where you think the tiles will go and hope! Lol Using border tiles you can actually cheat the pattern of the floor eg move tiles 20 mm or so to one side so they come together around a waste.

Woo Hoo - I just learnt how to scribble and draw on other peoples pics! Now I can really cuase mischief LOL!

Thanks Doogie / Michael

I will go with the idea of centreing the waste in the main floor and using a border tile around the whole floor. Michael has pointed out that the inverted pyramid would not work with large tiles in the rectangular shower set down so maybe I will look at using one of those MIZU floor grates across the shower inside the set down and just slope the shower floor (1100 x 875) to the grate.

What do you think about that idea or would it look crappy?

I will be laying the new concrete floor myself so I have a few days to use my limited plumbing skills do some minor adjustments to the position of the floor waste outlet after the plumber has gone. That will give me time to select the actual floor tiles and lay them out and exactly position the waste in a diagonal tile joint.

Do you think if the whole floor is waterproofed with care that a 5mm fall to the waste is OK?

Hi juan - a with a 5mm fall to the floor waste , puddles will still form and hang around ( or be sucked up by a bathmat) - but if you get a lot of water on the floor 5mm is enough to move it toward the waste.

You may want to consider using narrow grout lines and even using special silicone for the grout.

the whole theory behind floor wastes ,as I understand it, is that water should not sit on tiled surfaces for very long and /or that, in an overflow situation, water doesnt run from the wet area out the door to some other area.

I have been told that cement based grouts are designed to suck up small amounts of water but I'm not sure that is the best practise.

In Europe a lot of people have flat tiled floors in bathrooms and use a special sqeegee to rake the water into a waste.

The strip shower waste looks ok - in the shower. Not sure about in the floor though. The 900mm looks better me thinx. I've got a similiar thing in my shower - damn stainless steel needs cleaning after every shower though!

Hello Juan, I have attached a pic of a shower floor I'm working on. (This was taken before this ensuite was completed so it is lacking grout, silicone, etc, but you'll the idea).

I didn't use the diagonal tiling technique that was exhibited in Mic-D's shower photos, because the rest of the floor does not have diagonal tiles. However, the cuts follow the `inverted pyramid' that I created when I did the sand and cement mortar base, as described by Mic-D. It looks fantastic now that it's finished, I need to take some more photos. I made things a lot easier too by using a square shower grate. I was going to buy one of Mizu shower channels, but they're so expensive! The small one is really pricey, and I also thought the only way it would look good would be to get one long enough to do the entire width of the shower (900mm). The 900mm one was I think well over $600, it's been a while since I did the shopping around. All I remember is it was WAY too much to consider!

I have actually made the aluminium angle sit above the height of the tiles by about 20mm, as you can see in the photo. It is a very confined ensuite, and the shower is very close to the doorway. In my experience of stepless showers, water gets all over the bathroom floor and I find it annoying, and I don't have a floor waste in the ensuite either. I'm very happy with the sleek appearance of the small aluminium hob and it will prevent any puddles in the shower from finding their way into the rest of the ensuite.
