The rounded profile removes the square corner where dirt builds up, and the smooth, non-porous surface is easy to clean. Coved junctures do that job where the floor meets the wall. With the CoRound™ system, three things change on the job site. No sealant line required along the wall. Pre-formed corners, no silicone-filled field cuts. No resin or cement to cure.

Why Does a Square Corner Matter?
Square corners can trap dirt and water, and that is where bacteria can grow. A rounded profile leaves fewer of those spots and makes them easier to wash out.
FDA Food Code §6-201.13 requires floor and wall junctures to be coved and closed to no larger than 1 mm (1/32 inch) where floors are not cleaned by water flushing, and coved and sealed where they are. Check requirements with your local health department.
In particular, for kitchens, read our commercial kitchen cove base guide.
Where Do CoRound Profiles Go in a Room?
Specifically, CoRound is a system of rigid PVC profiles that rounds off the corners of a room: where the wall meets the floor, where two walls meet, and where the wall meets the ceiling.
- Wall-floor juncture: the CoR Skirt S or CoR Skirt B sanitary base.
- Wall-to-wall and wall-to-ceiling junctions: the CoR 4 cove base, which snaps onto the CoR 4 Base.
- Base of the panels: the CoR Channel, a PVC base track that the CoR Skirt snaps into.
Also, in a washdown, water runs from the ceiling down the walls to the floor. With CoRound profiles at the ceiling, in the wall corners and at the floor, it meets a curve, not a square corner, at each junction.
What Happens at the Wall-Floor Juncture?
To begin with, at the floor, the CoR Skirt sanitary base covers the wall-floor juncture. Flexible co-extruded lips press against the wall and the floor and follow small surface irregularities, closing the juncture.
Moreover, CoRound is fastened to the wall, and its flexible lip rests on the floor.
What Does “No Sealant Line Required Along the Wall” Mean?
For example, on ribbed panels, a metal base usually needs a bead of sealant along the wall: a second step, and exposed sealant can turn dark and attract dirt over time, leaving a dark line between a white wall and a white base. With CoRound, no sealant line is required along the wall.
On standard cold storage panels with mesa or wide-rib profiles, the flexible lip follows the ribs. As a result, the flexible lip minimizes gaps along the wall, with no sealant line required.
How Do Pre-Formed Corners Change the Job?
Similarly, with a metal base, each corner, column and door opening can mean a miter cut on site and silicone to close it, and the result depends on the installer’s hand. CoRound has pre-formed pieces for them: joints, 90° inside and outside corners, and end caps.
As a result, the curve comes from the factory, not from the installer’s hand: it is the same all the way around the room.
Which Materials Can Make a Coved Juncture?
For instance, a tile cove base has grout lines, and grout can hold dirt and moisture. CoRound profiles have a smooth PVC surface with no grout lines. See our quarry tile comparison.
In contrast, the CoR Skirt is a rigid PVC sanitary base. Unlike a rubber base, it can be screwed or riveted to the wall, so it doesn’t have to depend on adhesive. More in our rubber cove base comparison.
With a resin or tile cove, a repair can mean cutting out a section, redoing it and waiting for it to cure. For details, also see our resin coving comparison.
A stainless steel base can dent and rust, and the exposed silicone along it can blacken and come loose. CoRound replaces it with no welding on site, and it costs less than stainless steel. Also, metal bases and channels can rust where water sits. PVC does not rust.
When Do Installers Add Silicone?
Silicone is optional: not required for installation. For the CoR Skirt, in wet areas, installers can add a thin bead of neutral silicone to help keep water from getting behind the profile.
Why Choose Panelmart for a Sanitary Cove Base?
- No sealant line required along the wall: one less step on site and, as a result, one less cost that can recur.
- Pre-formed corners, no silicone-filled field cuts: the curve comes from the factory, not from the installer’s hand.
- No resin or cement to cure: there is nothing to mix, trowel, weld or cure.
- One system for the whole room: base track, sanitary base or heavy-duty curb, cove base for wall and ceiling junctions, pre-formed corners, end caps and corner guards, all made to fit together.

Frequently Asked Questions
Can you replace a damaged length?
A damaged length can be replaced on its own: the rest of the run stays in place.
Does a rigid PVC cove base install on tile or drywall?
Yes. Installs on insulated panels, FRP-covered walls, tile, masonry and drywall. So, if in doubt, ask for a free sample to check it on your wall.
Can I see the profiles before I order?
Yes. Free samples are available on request: email [email protected] and list the profiles you need.
