3 Curbless Systems
Choose the drain body that fits your project
3 Curbless Systems to Choose From
A curbless shower creates a clean, open look and removes the step-over barrier found in traditional showers. That makes it easier to access, easier to clean, and a strong fit for modern bathroom design.
Linear drains are a popular choice because they allow water to move efficiently to one side of the shower while supporting sleek tile layouts and barrier-free entries. Shop linear shower drains and see current prices.
SHOWERline Drain
Cost-effective curbless linear drain system with a PVC drain body and grouped size options.
PROLINEdrain
Commercial-grade stainless steel drain body for projects needing a more robust premium drain system.
WALLdrain
Hidden-in-wall drain body for the most seamless curbless tile shower appearance possible.
Choose Your Drain Size
Hint: Curbless linear drains are commonly placed left to right, either at the front entrance or the rear of the shower.

How to Pick the Right Drain Size
Start by measuring the shower opening from wallboard to wallboard. That one number decides your drain. The product spec sheets and installation instructions have the details for each system.
SHOWERline or PROLINEdrain
Choose the drain just smaller than your opening. Then use the trough extensions to carry it all the way from wall to wall.
WALLdrain
Choose the next size larger than your opening, then cut it to fit wallboard to wallboard.
Plan the Flow Rate
Your drain needs to keep up with the shower head. Plan for this much flow per drain:
5 GPM
Curbless shower, drain at the entry
10 GPM
Curbless shower, drain at the back wall
10 GPM
Any curbed shower
Curbless Shower Sloping Panels
Curbless shower pan sloping panels are lightweight, pre-sloped panels designed to create the proper pitch so water drains correctly toward the shower system.
These panels can help save time versus building slope manually and are installed over the subfloor before waterproofing is applied. Shop curbless pre-sloped shower pans for tile or curbless shower kits for tile.
Popular Sloping Panel Options
48" Deep Panel + 26" Extension
For showers up to 74" deep
48" Deep Panel + 52" Extension
For showers up to 100" deep
Framing the Floor for a Curbless Entry
Here’s the order we recommend for a curbless entry with a back-wall SHOWERline. See also our 4 linear drain installation tips to remember.
- Cut out the subfloor inside the shower footprint (often 3/4-inch OSB). Don’t damage the joists below.
- Add blocking between the joists so you can drop in new 3/4-inch OSB at the lower height, and fasten it.
- Joists running parallel to the drain: block about 10 inches on center to support the drain trough and the subfloor next to the drain flange.
- Joists running perpendicular to the drain: check your local building code before you modify any joist to fit the sloped trough.
- Using sloping panels? Set them tight against the drain flange so they end at the entry.
- Check your finished floor heights to see if you need extra substrate to build up.
Why So Many People Go Curbless with Tile
No Step to Catch a Foot
The bathroom floor flows right into the shower.
Easier Cleaning
Larger-format tile means fewer grout lines to scrub.
Your Choice of Finish
Nearly any tile or flooring made for showers will work.
