curbless shower questions

Hey Everyone,

Long time reader first time poster have a quick question.

We are attempting to build a 4' x 6' curbless shower into a bathroom remodel, we do not have the luxury of reframing the floorjoists sadly so unable to create a larger floor joist drop that would normally be used for curbless.

The floor joists are 2x8's and span around 15', we will be building up the bathroom tile floor with scratch coat, heated floor wiring, another scratch over that, thinset and tile I would expect it to be almost 1 inch after all said and done.

Can anyone recommend a good way to complete a slope to a linear drain along the back wall without cutting floor joists?

Are you sure about the 2x8 and 15' span? That would make for a VERY bouncy floor wholly inadequate for tile.

As for the curbless shower without cutting joists, I would be looking at either Finpan's Clearpath Shower kit or Wedi.

I agree with Nate. Double check that joist span. At best, it should be no more than 10-11 feet.

Your linear drain placement is going to be dependent on the joist direction and dimensions of the shower. I would look at the two that Nate mentioned, and contact their customer support directly with your plan.

If the shower is 6' from front to back, I don't know how you'll get your required minimum 1/4" per foot slope without having a bump at the opening, or building up the floor in the rest of the room. A centered linear drain might be more feasible.

The top ten reasons to procrastinate:
