I've used a Tile Redi pan one time, and won't use it again. Aside from the problems I've heard from others about it flexing way too much and popping tiles, My problem is that in order for it to be used properly, you almost need to put it in place, and THEN plumb it and frame around it. If the plumbing's just a little bit off, or if the framing's just a bit too wide (even so little as a 1/4- 1/2") you're going to have a nightmare making this base work.

Kerdi makes a tray/slope that's made to fit in a standard tub opening.

Wow, thanks for the quick response. Since this is a remodel, it sounds like a "no" for lots of reasons.

DH ordered a Tile Redi a few years ago for our total master reno and I was so stressed looking at the thing. We got it before stumbling onto this wonderful place. It was the whole thing, the material, the preparation, the flange, the screw... just made me cringe.

After much debate, I begged and pleaded for us to just chalk it up to a loss and go with the kerdi pan (which I thought when I had initially looked at it a few years back only came in set sizes which is why we didn't get it, but then upon further research the following year, found it to be customizable!)

Our tile redi pan was only partially coated with redguard which was a big red flag to me that something just wasn't right, also I couldn't see how we would easily continue the flange up the wall without a whole lot of extra shimming or recessing... just wasn't worth it.

Unless you design the shower floor around the drain, like a mud pan, you will likely need to adjust the plumbing anyway. I DIY'd the Kerdi tray and it was really fine. One or two little bumps, but nothing unmanageable.

Wedi also makes a system that is good, but pricey... although it is probably the easiest of them all from what I could tell from my research, but never got to see one up close and personal.

Umm, the Kerdi tray is specifically made to remodel a tub to a shower. Or you could use Kerdi with a mud bed to further customize it.

I just saw one made by Kohler - it was beautiful. But, my builder said his plumber can putin a great shower floor for a lot less money. I think it was a little over $500.00. It comes in a few colors and it looks like glass...

It shouldn't be more than about another hundred dollars over that for tile.

Oh yeah-- that price would include a 4.00 a foot allowance for tile.

terriks, I was responding to Bill, we cross-posted. I'll have to investigate the Kerdi tray.

Designers Marble in Woodinville can make a custom pan to fit what you describe.Very sturdy,and available in lots of colors.
