What the AI looks for in Shower Bases & Pans
- Drain size
- 2-inch drain for showers under US plumbing codes A 1-1/2-inch drain is generally not allowed for a new shower and can pool water.
- Drain location
- Center, left, right or end drain must match your existing rough-in Moving a drain means opening the floor, which usually costs more than the base.
- Floor slope
- About 1/4 inch per foot toward the drain for tiled pans Less slope pools water, and much more feels uneven underfoot.
- Tile flange and curb
- Integral tile flange on the wall sides, and a curb height that fits your door's threshold Without a flange, water can wick behind the walls. The curb sets how the glass door seals.
- Bedding
- Set acrylic and composite bases on a mortar or setting bed if the maker calls for it An unsupported base flexes, creaks and cracks around the drain.
Brands that matter
- DreamLine: Many acrylic base sizes that coordinate with its shower doors.
- Schluter: Waterproof foam tray systems for tile showers.
- Wedi: Presloped foam bases for tile, strong for curbless builds.
- Swanstone: Solid-surface bases that resist chipping better than thin acrylic.
- American Standard: Mainstream acrylic and composite bases.
- Oatey: Pan liners and shower drains for traditional mortar-bed pans.
What to avoid
- Thin ABS bases without reinforcement
- Bases without a tile flange in a tiled alcove
- Ordering before measuring the rough opening and drain center
Questions
Shower base or tiled pan?
A prefab base is faster and nearly foolproof. A tiled pan (foam tray or mortar) gives custom sizes and curbless options but needs careful waterproofing.
