Which Shower Curb Kit Size Do You Need?
Part of our Showers guides.
Curb kits are sold by the footprint of the sloped pan. Measure your finished shower floor (inside the curb) and pick the next size up, then trim if the kit allows.

Center or offset drain?
Tub-to-shower conversions usually have the drain near one end, so an offset kit (like the 38x60 or 60x38) avoids moving the drain. New builds can use a center drain for the simplest slope.
Curbless?
Large 60x48 and 72x72 kits are popular for walk-in showers. A truly curbless entry needs the subfloor recessed, which is structural work.
How to measure for a kit
- Measure the shower floor inside the planned curb, wall to wall.
- Subtract wall backer board and tile thickness if walls aren't built yet.
- Note the drain position relative to the walls.
- Pick a kit equal to or slightly larger, then trim if the kit allows.
Linear vs center drains
Center drains need a four-way slope, which suits small tiles. Linear drains slope the floor in one direction, allowing larger tiles and a curbless look at the entry. Check which drain type each kit supports.
Curb height
Kit curbs set a standard height for containing water. For accessible showers, choose a low curb or a curbless design, which requires the subfloor to be recessed so the pan's thickness doesn't create a step.
Kits vs mortar beds
Traditional mud beds are still used by many tile setters and can be made to any size. Kits save weight and time and give a consistent slope, which is why they're popular for DIY.

Frequently asked questions
Can I combine two curb kits?
Generally no; use one kit sized for the whole floor so the slope runs continuously to one drain.
Is EPS foam strong enough?
EPS shower pans are designed to be bonded with thinset and covered with tile, which spreads the load.
