Re-tiling a wet room floor?

[RhysHughes78]

Hello there everyone, I just have a question that I'm hoping to get some advice on if possible. I have been to look at a job where the customer would like their wet room floor re-tiled, I stated to them that I'm not sure what damage would happen to the substrates once I lift the tiles, especially as I don't know what has been used underneath! Has anyone done anything like this that might be able to advise?

Cheers.

Rhys.

I have done this a few times. Although we can't discuss pricing, you will need to acome to an agreement with the customer to rip out and when you know what's underneath, you can then discuss time and materials needed to put the job right. Most people will understand this.

can I ask what sort of circumstances you could come across bri? cheers

For example, a shower is leaking and it's coming through the ceiling downstairs. Until the old tiles have been removed, you will have no idea how bad the damage is, what materials are needed to repair and most importantly, how much labour will be required to put it right. I've got a pic somewhere of a shower that had been leaking for years, the damage was unbelievable, you would have had no idea what was lurking underneath until everything was removed. I'll have a look for the pic now.

sound bri. so he should even be prepared to replace damaged joists? lol

Hi Bri, thanks for getting back to me, that's exactly what I said to the customer actually, they were fine with that. I was just wondering if when I pulled tiles up if it would cause any damaged to the tanking system etc? I know this is a hard question to answer as every job is different and you never know whats going to happen.

It's a possibility, here are those pics


Had to chop out a section of the stud and replace, the original tray was just a piece of ply with no tanking anywhere. Built a new frame, new former, tanked then it got tiled.

I would imagine the tanking will get damaged, it's one of those jobs that you will just have to play by ear. Strip it back and then you will have a clearer picture of what is actually required.

Ok mate, cheers. I thought so, I told customer I'd give them best and worse case scenario. Cheers again.

Consider the worst and tank the floor. also consider fitting under floor heating.

It was for the waste yes, and the existing shower door had to go back so, had to be the same size hole for it to go back into. It was an old cottage and, if I recall correctly, if the tray had been fitted flush to the floor the joists would have needed cutting and the waste pipe was cut straight through the sandstone wall and wasn't feasible to drop it down.

another example of every job not being the same! thanks for the info mate.

Just recently done this one Rhys

I told the customer that I would remove the offending tiles and charge for that procedure.

Next step was to assess what needed to be done to remedy the problem.

The problem was tiles loose, grout out of joints, broken tile, water coming back up through joints when walked on

Tanking was sound, had to just recreate falls to corner of drain and then tile with new mosaics

Did the old tiles have a mesh backing (picture 2)?

No they were 330x330 ceramics it's just the imprint from the back of the tile in the adhesive.

 

[Mr Tiler]

it really does look like mesh lol
