View Full Version : Roman tub replacement.

Done the ensuite (Thanks for all the help CX, Davy, Wolfgang, Jim, Dan, and Kevin, to name a few!). Time to tackle the main upstairs bathroom, with a disgusting old tub I've been using as a construction washup area.

I've been looking at inserts to replace the tub, but it seems there are tubs meant for showers, where the tile goes over the tub on two or three of the sides, and then tubs with a lip all the way around that don't look like they are meant to be in a shower, just used as a tub. Since my tub doesn't have one full open wall, I don't know that a shower tub will fit properly? I hope I'm making some kind of sense here.. hopefully the photo will help explain. With one end of the tub extending passed the wall, being covered on all sides, I don't know if I could make a proper tile to tub transition?

Hi Jesse,

Tear it out. Redo it as a roman tub or put a floor in and make a conventional shower out of it. Don't mess with inserts.

Thanks for the response John. I'll look into doing another Roman tub but I'm not sure I want to go that route from what I've seen people here saying about them (seems quite difficult).

Would like to still have a tub though, rather than converting to a shower.

Just found this product, anybody have experience with this or something similar? Seems like it would solve my problem, I could get a regular 72" drop in tub and then just install the tile flange where I need it.

I would tear it all out and try to find a tub that has a flange already made on the tub.

I don't think any tub will have a built in flange to go around all three sides on the one end of the tub sunken into the wall though.

How does that Home Depot flange seal to the tub surface I don't understand this? What's in that little pop out feature next to that tub that's causing this problem?

What Jessie said, something will have to be done about the third wall. May even have to fur out the wall to fit the tub.

I've never installed one, Teddy but I believe epoxy is used to bond it.

I'd probably try to use a drop in, then fur all the walls out above the rim so that the tile is held back from the inner edge of the rim by a minimal amount, no more than 1/4". Since the rim will probably be at least an inch wide, probably more, it should give you enough space to bond Kerdi to it to create a seal.

Will require some very accurate measuring and framing, and probably some compromises in adjoining wall surfaces.
