ICON RV Shower Pan Sizes & Drain Locations: Replacement Guide
A replacement RV shower pan needs more than a similar outside length and width. Match the overall footprint, pan depth, shape and the location of the drain connection underneath. ICON makes separate left-, right- and centre-side-drain versions. This guide compares specific rectangular models to help you narrow the options before buying.
Measure the space and original shower pan
Overall length and widthMeasure the full outside dimensions, including the rim and flange areas that meet the wall and shower surround. Do not use just the floor space inside the basin.
Height and clearanceMeasure the pan depth and the room under it for the waste plumbing. Taller pans can change the installation height and may interfere with adjacent cabinetry.
Molded drain positionCompare the drain's location relative to your existing plumbing and the actual manufacturer dimension drawing. Left and right labels must be checked against the pan's original orientation.

The measurements below follow ICON's manufacturer catalog and correspond to exact MPNs linked to our listings. They describe the pan's overall length, width and depth, not the required floor cutout.

Drain preparation: ICON describes these pans as having a molded drain location ready to be drilled. Do not assume the hole has already been opened or that a drain fitting is included. Check the exact pan and instructions before drilling or installing fittings.
Compare replacement shower pans by size
Each card links to the exact part number in our store. Review the current product pictures and the manufacturer dimension drawing before ordering.
Compact shower pans
For shorter bathroom footprints. These shapes and drain positions are different; a close external size is not enough to establish a replacement.
36-inch shower pans
Compare the 15240 left-drain and 15241 right-drain configurations. Both are 36 1/8 × 23 7/8 inches overall.
Long rectangular shower pans
The 15242 and 15445 have different heights, lengths and drain locations. Match the existing installation rather than resizing around the nearest option.
Wider shower pan
The 15460 pan has a wider 29 3/4-inch footprint and centre-side molded drain position.
Shower pan replacement questions
Can I replace a right-drain shower pan with a left-drain version?
Only when the plumbing, support and surrounding bathroom layout can accommodate the different molded drain location. A matching outside size alone does not prove interchangeability.
Does the shower pan come with an open drain hole?
ICON's catalog describes a molded position designed for drilling. Confirm the exact supplied pan before arranging plumbing or drilling any opening.
Can I use the overall pan size as the floor cutout measurement?
No. The overall exterior length and width are different from the required support area, drain opening and any surrounding structure. Measure your old pan and refer to the appropriate ICON installation drawing.
Shower drains and bathroom plumbing
For drain grids, strainers and matching fittings, see our shower and sink drain parts reference. The RV bathroom sink size guide covers related bathroom fixtures. Each shower pan requires the correct waste plumbing for its own drain design.
