shower in old flat

[joe bloggs]

next job, my son's bathroom, a third floor 100+y old flat in Aberdeen.
rough sketch here

First off is the shower, enclosed on 3 sides by stud walls with door and fixed glass on fourth . LH and back stud walls are to be built, RH wall is stud and will have lath and plaster replaced with PB.
I've done bathrooms before (see http://www.tilersforums.com/new-members-say-hi-here/26743-trouble-ahead.html and http://www.tilersforums.com/tiling-forum/26769-att-joe-bloggs.html ) but tanking a shower is new for me.

My intention is as follows:

build stud work,
fix plumbing in walls
cover with 12mm PB . The walls sized so as to just fit in tray and tanking
use Mapei 'shower waterproofing kit' to tank from floor up 1 metre
Lower shower tray onto mortar bed (on floorboards)
fix trimlux to PB/tray (I've used this before)
tile (large, porcelein) up to ceiling using KERAFLEX , no primer.

Any advice would be welcome. Its very important that the shower doesn't leak onto the flat below.:no:

I've seen cement used under showers trays and then become loose but have seen anything from plaster to expanding foam used.

I don't like trim you speak of around the shower tray, they probably work but not one I'd use.

I'd take the tanking up to aleast 1.5 m high

new ceiling, stud work, PB. plumbing,waste all in; tanked (1.5m)enclosure with kit, will use tape and goo on tray edge when fitted, like I think Mapei intended. Planning to tile top half of wall with 600x300 porcelain (Jakarta, grey, polished ) before tray fitting.

can I cut these tiles with a score cutter? I've got a B&Q wet tile saw but was hoping to restrict its use.
and can I use my usual method of cutting large holes,(for valves, electric box) ie first a 6mm tile drill and then jigsaw?

Have to be a decent dry cutter for porcelain tiles but thats the way to go

well, I've got one like this:-

which is better described as 'cheap' than decent; it did OK for my en-suite tho' but they weren't porcelain. What are the criteria for a decent cutter?

being able to change the cutting wheel for a start, they don't last forever and that one looks fixed. You could give it a try, needs a sharp fast break though

I gave it a try, it works fine; only big enough for the 300mm direction tho', not the 600mm. I have noticed when it comes to snapping any sort of scored tiles on these machines that altho' the tile doesn't snap with an initial very hard press that giving it several hard pushes up and down the length of the score it will eventually go with a fairly moderate push. Just musing that the initial presses start some non visible interior cracking which finally weaken the tile, not what you'd expect.

i'm not sure about your method with the dry cutter:dizzy2:. You will need to cut the 600mm length so i presume you'll use the wet cutter or get a better dry cutter like Montilit 63 -p2 or similar.

I suppose I should finish my bathroom now, but as its a nice day I'll go for a ride on my bike instead.
