My First Wetroom

[b1gbrad]

Hi Folks.:wave2:

I've yet to post or introduce myself so ..."hello"! I've been working on my wetroom for a few months now and have took inspiration, ideas, advice etc. from many of threads on here, so thanks chaps! So I thought it was about time to post a few pics and progress of where I'm upto.

This was our old en suite in our recently purchased new house.


Nice isn't it! :lol:

So, it was time to rip everything out.



My plumber friend sorted the pipework for the repositioning of the sink and toilet, and the towel warmer and waste from the shower. The floor was replaced with 18mm ply. The Marmox showerstone was raised higher with more ply to accommodate the inevitable extra height of the underfloor heating, screed and the tiles.

Re: My First Wet room

Hello and thank you for introducing yourself. Will start off by saying brave brave man, a wet room is no DIY project IMO. Just be sure to come on here and get the advice you need BEFORE you do each stage, there is sooooooo much that can go wrong. Dont mean to be negative, it is just heart breaking when these projects end up costing 5 times the amount it would cost to get a pro in due to water damage.

That said, best of luck with it and be sure to keep us updated along the way

Re: My First Wet room

Hi folks. Thanks for the feedback.

I'll upload some more pics soon of my progress - I've got a lot further than just the above photos. You'll see I've took a belt and braces approach - perhaps spending more than I need on preperation. But I only want to do it once! :smilewinkgrin:

Some lights....

...on the smoothed out ceiling. I HATE artex!

Floor down

Waste for toilet moved through the bathroom wall

Hi,

Thanks for posting details of your project. What thickness Marmox board did you use on the walls? - and did you use the same thickness on the floor? How did you get on with installing the Marmox? I'm working on my own wetroom project, and am considering replacing plywood currenltly on the stud wall with Marmox (I have posted some details of my project on the same forum.


Many thanks...

Hi there,

Installing the Marmox has been pretty staight forward; their website has very good installation guides. I made sure i used plenty of their sealant in the holes I drilled for the stainless screws, around the edges of each board and then over the backer board washers. I used 10mm on the walls and, as floor height was at a premium , 6mm on the floor. I fixed the later with tile adhesive and screws + washers. I think they recommend to use 10mm minimum for both the floor and walls, but I replaced all my subflooring with new 18mm ply so I'm confident it's all strong enough.

I'm currently tiling so I can't really comment on it's longevity in use...but fingers crossed!

 

[b1gbrad]

I then mapegum all joints and proceeding to cover the whole wet area with a few coats.

Then the U/f heating went down

Ready for the screed. This was a particulalry cold night's sleep - I'd left the window open! :iamwithstupid:

Looking good Brad.
What is your next plan, tile the walls then the floors???
You're doing a great job there so i (and i reckon the other guys) would say tape the wall floor intersection again and cover in mapegum, then tile the walls. Then tank the remainder of the floor, or better still lay either Ditra matting or Dural C1 on the floor, tape the joints.
These measures will make sure the room is double tanked and the uncoupling membrane will also allow any lateral movement in the floor generated by the underfloor heating.
This will give you a really good quality, bomb proof wetroom.

Hi - thanks for the follow-up and further pics....


I can see you have applied Mapegum over the Marmox panels on the all, too. I guess this is just part of the 'belt and braces' approach?.... as far as I can see from Marmox's website, they say their panels are ready for tiling (once the edges have been sealed with silicone).

I can also see from the photos that the Marmox washers do protrude from the panel a bit. Have you found any difficulty with this now that you have started your tiling. (e.g. any problems getting an even adhesive layer & tiles flat??).



Many thanks..

Yes, they do protrude somewhat, but I've started tiling with quite a thick adhesive bed to compensate. It'll take quite a bit longer to tile, but I'm sure it'll be worth the extra effort.....hopefully!

Thanks for the advice, but it's a little too late! I've already tiled the floor and shower area (I'll post the pics up soon). Most of the shower area will be sectioned off with glass so I think the floor will be mostly protected from water, so hope the marmox, tape, sealent and mapegum I've used on it will be sufficient.

1st few floor tiles laid

Shower area

I had a few problems with the waste; it was way too high and these mosaic tiles are very shallow. I ended up cutting it down a little to get it as low as possible whilst keeping a reasonable fall in the tiles. I'm happy with the results

 

[Bolter]

Looking good!

 

[Drastik Lee]

Looking fab keep em coming :hurray:

 

[b1gbrad]

After my small disaster with bowing tiles I had to take down what I'd started

And this is what happened!

So I've had to rebuild the wall with backer board

At this point I was a little dejected so started tiling the main shower wall:

The mosaics are really tricky. I found myself putting them on as best I could, waiting for them to go off a bit and repositioning them again.....and again. And then again. Practice makes perfect!

Hope your feeling better about the project after the bent tile issue!! It looks a quality installation to me brad! Looking at your 1st tiling pic on post #17, I love seing a spirit level accross the tiles, it shows you are taking pride in your work! I also like your screeding! ...a very honest and lasting wetroom you are creating there, good luck!

Up until this point I'd been using Ultraplan flexible and extended set. The tile shop I went to recommended it, and I know no different. But I was running low and they were shut (it was a Sunday). So I went to B&Q and bought some Mapei Flexible (not extended set) adhesive. WOW! What a difference. It's like I turned into a pro overnight (well, not really). I made progress twice as quickly as using the ultraplan stuff, it's a nicer substance to work with and it grabbed the tile initially amazingly well. I won't be using anything else again!
