Narrowboat refurb - Back to the bathroom...

Just need it square so the door and panels fit to it. In a house I'd use a level but here I can't. Looks to me that there's more structure towards the drain so that side won't sink into the mortar so much. If it had a flat base as many do I wouldn't worry.
I'm temped to put dollops at each corner and the centre as it looks like you could fit legs to raise it up.

 

Maybe I could fill it with mortar then when it's gone off turn it over onto a thin bed of mortar.
It looks flimsy to me and if it cracks I'll be cheesed off.

 

That would indeed get it level. The base and sides are all square at the moment.

 

Yep, and the tray, I have stuff for that - SBR Bond.
I keep telling myself I'll do it tomorrow, I've been saying that since Tuesday.

 

Timber would probably be my preferred option with a timber floor.

Our shower cracked and you can get repair kits, but it certainly isn’t an invisible fix…. White was more grey!

Ours was installed on the adjustable pedestals which is just pointless when most of the weight of a person showering is in the middle of the tray… asking for trouble.

I’ve since put a bit of timber reinforcement under the tray but I’m waiting for the electric shower to give up the ghost so I have a reason to refit the whole shower properly with a decent timber frame under the tray!

 

I've got 18mm ply floor + another 18mm ply on top of that. if that cobweb pattern was level with the outer rim I'd just fit it dry TBH but it's recessed average 10mm and as wonky as a wonky thing.

 

Will you have the waste plumbing all above the floor or does it go through into the bowels of the boat?

If it’s the latter, why not just use a sheet of 9mm or 12mm ply, or better still Marmox or cement board cut to shape below the tray?

 

Drain is under the floor but the bottom of the tray is all over the place, not possible to support the centre with anything prefabricated. The drain bottom and the perimeter are the same level but the rest...

 

Would inverting the tray, filling it level with the sides, then fitting work?

 

Just what I was considering a few posts up^.
I think it would probably be a daft idea though I can't put my finger on exactly why I think that.

 

Bits od sqaure wood - that's theight I want, So I'm thinking dob mortar here and shuffle it down onto the wood.
Anyone see a Problem? I can - Mortar getting between my wood and the tray, stopping me getting it level.
Maybe I cut the wood shorter or perhaps have 4 short pieces away form the corners and any mortar. Yep Think I'll do that.


Here's the crappy tray again...

 

What do you mean "bring the mortar away"
The correct amount seems impossible to judge as the edges and corners are quite a bit deeper than the middle. I'll take some pics BRB.

 

It's truly a crappy tray, but they don't ever show pictures of the back do they?
