I was referring to their
shower system products like the Kerdi membrane, Kerdi-Board, and shower pan kits. I rebuilt my shower the old fashioned way: built-up curb, deck mud pre-slope, PVC liner, deck mud over that, Hardiebacker on the walls for tile, etc. I schlepped a
lot of heavy stuff up those stairs, lemme tell ya. The Kerdi products would have lightened the load considerably and made things go much faster. They're pricier than traditional products but it would have been well worth it to me.
I have used their
Ditra floor tile underlayment on the floors for our master suite remodel, rather than Hardiebacker. It's lightweight, cuts with a utility knife, and you don't have to have drive a million cement board screws. You put it down with thin set. It was a real back and knee saver when I tiled the master bedroom:
That's almost 320 ft² of floor. If I had lugged that much backer board upstairs and screwed it down, I think I'd be crippled now.
I've also used their transition profiles and edge trim...and if I had to do it over again, I'd take hard look at the in-floor heating system.
