Drop-in Tub tiling- lip on frame or on tile?

Hi there,

I may have screwed up. I hope its not the end of the world if I did.

My plumber assured me that I could set my drop-in tub directly on the frame platform, then tile up to the lip of the tub. So I did exactly that.

However, I see in a few different places (youtube etc), the tub is dropped onto the final tiles.

Are there a definitive "right way" and "wrong way" to do it?

Thank you for your insight.

Jamie.

Far more likely to leak if you try tiling up to the tub.

Pictures would speak volumes since we can't see what you see.

Pics would be great. But if I assume what your mean then your plumber is correct. Your backer board sits on the top of the tub flange. You tile over that flange onto the tub ledge. Then caulk after grouting to seal it.

Likewise, waiting on pix... Don' plan on sitting your tub on tile. They will crack. Make sure you support the tub at the floor level as well. It cannot hang from your flange frame.

You are fine. There is no shower associated with this, is there? If so, you hopefully have splash considered.

Thank you!

I appreciate the feedback very, very much.
I shall carry on!

(there is no shower associated with this installation; the mixing valve is going)

Thank you again,
Jamie.

Hi Jamie & all,

For those wondering what Norm in #4 was thinking when he thought the plumber was correct. I'm thinking Norm misunderstood the situation. He thought it was a standard tub installation with backer board on the walls only.

I say the plumber just wanted to install the tub and get out of there. He did you a dis service. The deck should have been tiled first, then the tub installed.

* Did you set the DensShield on the deck into fresh thin set mortar?
* What's the plan for Redgard, Where will you be applying it?
* Be sure to use the mesh tape on all seams and all corners, inside and out.
* That is not gonna be a waterproof install, but since there's no shower it'l probably be fine.
* What specific adhesive will you be using?

To answer your questions Jaz

* Did you set the DensShield on the deck into fresh thin set mortar?
> Just set it straight on the 2x4 frame.

* What's the plan for Redgard, Where will you be applying it?
> I had orginally intended on applying it everywhere! But turns out I have more than enough Kerdi left over from the adjacent shower installation. I will use Kerdi everywhere.

* Be sure to use the mesh tape on all seams and all corners, inside and out.
> I dont think this applies anymore considering the Kerdi membrane plan. I am going to use this everywhere. Please correct me if I am wrong.

* That is not gonna be a waterproof install, but since there's no shower it'l probably be fine.
> I hope so.

* What specific adhesive will you be using?
> Its Custom Premium Plus Standard (unmodified) thinset. Used this because of the Kerdi membrane.

I'll have to agree/disagree slightly with Jaz on points. Yes, the plumber should have completed the "plumbing" part of the install, instead of leaving the original valve in that position. Now, you have to wait before you can do the head wall. I never allow a tub to sit on tile, although the finish lines will be smoother. Too much flexing and irregular weight distribution can cause problems with tiles and grout lines possibly cracking or becoming dislodged. I know, in a perfect situation it will work, but seldom do we run across that.

James,

That's wrong. You should spread thin set under the DenSheild. In addition your install is a little different than in most other cases. Usually you'd have plywood or OSB over those 2x4. But since the purpose isn't to bond the DenS to the framing, I think you'l be ok with just thin set.

What's the plan for Redgard, Where will you be applying it?

That's wrong too. You should not apply Redgard, Kerdi or any other membrane over DenSheild which already has a plastic surface.

Be sure to use the mesh tape on all seams and all corners, inside and out.

Ok, I did above. No Kerdi for you. The best thing to do now is to mesh tape and thin set all the seams & where the fasteners punctured the surface etc. Then apply 2 nice coats of Redgard ONLY on these taped/thin set areas.

What specific adhesive will you be using?

Aha..... You're in Canada? That wouldn't be my first choice but at least they still sell Premium Plus there. Down here it's not available and the only unmod they carry is Custom Blend. Most of us think it's just a small step above dirt.
