Hello, I am not sure this is the correct forum for this question, so I trust the moderator will move it as necessary. The question is "does anyone have experience with curbless showers?" I am building an addition for our daughter that includes a curbless or barrier free shower. Our permit was taken out as an ADA shower which has other than the normal 2 inch curb requirement. This all started when our daughter stayed in a motel in Oregon (where we live) that had a curbless shower. That is what she wants. No ramp, curbless. We have framed the shower floor for a 4 inch drop, and it is 4 x4 feet. My understanding of the ADA specifications is that a 3x3 (which is the absolute minimum) can have a maximum curb of 1/2 inch. If the drain is in the exact center and the slope is 1/4 inch per foot it looks like I can meet that requirement. I have reconciled that I will have to tile the shower walls and pan to achieve this as both the fiberglass units, and the cultured marble pans have a 3/4 inch curb. If we could afford it we would tile the whole bathroom and make it one big waterproof room, but that is not an option. How practical is the scenario I have described? Are we setting ourselves up for a continuously water damaged floor outside the opening? Any personal experience, and advice would be appreciated, both regarding use and construction. Thanks, Bill (Dukes)
