What is a zero threshold shower?
A zero-threshold shower is just that — zero threshold. It means you don’t have to step into a tub or basin. You don’t even have to lift your leg over a threshold of a few inches. With no barrier between the shower floor and the bathroom floor, you can simply walk right in and take your daily shower.
What is the minimum pitch for a shower drain?
about 4 percent
To efficiently drain, the recommended minimum slope for a shower floor is about 4 percent, or a 1/2 inch drop per every 12 inches from the shower walls to the drain. In traditional tile shower construction, this slope is established in the mortar pre-pan.
Where do drains go in a curbless shower?
“For curbless, we recommend placing the drain either across the whole entrance wall—not just the doorway—or across the whole wall opposite the entrance,” Van Landingham says. A drain that’s too narrow, or one that only spans the doorway, will cause water to pool or flood beside walls and in corners.
Why are Curbless showers so expensive?
With concrete slabs, cutting into the floor and moving plumbing are more complicated and labor-intensive. Because of this, installing a curbless shower on a concrete slab is typically more expensive than on a floor built with wood joists.
How do you slope a curbless shower?
Slope of the shower floor Sometimes less slope is specified in a curbless shower, such as 1/8” per foot. In some jurisdictions, a slope of 3/16” per foot or 1/8” per foot could be allowed for a roll-in shower designed to comply with the Americans With Disabilities Act (ADA).
How do you slope a shower floor?
Measure from the drain opening to the furthest wall, then round up to the nearest foot. Calculate the slope by multiplying the measurement by 1/4 inch. For instance, if the drain opening measures 2-foot 8-inches from the furthest wall, then the shower floor should slope 3/4 inch from that wall to the drain.
