ADA and Handicap Shower Bases and Pans

Updated April 2026

The shower base is the foundation of an accessible bathroom. For a wheelchair user, a person recovering from surgery, or a senior aging in place, the difference between a standard shower base with a raised threshold and a barrier-free or low-threshold base is the difference between a shower they can use safely and one they cannot. At Accessible Home Store, our shower base collection is organized specifically around that distinction: 69 bases and pans across four accessibility-focused categories, from barrier-free roll-in bases to low-threshold alcove pans, in a wide range of sizes, drain configurations, and materials.

All orders ship free on orders over $99.

ADA Shower Pan and Shower Base: Understanding the Terms

Types of Shower Bases in This Collection

Shower Base Sizes and Configurations

The majority of bases in this collection, 55 of 69, are alcove-installation bases designed to fit into a three-wall recess. The remaining 13 are corner bases for a two-wall diagonal installation, with one floor-mount base.

Common alcove footprints available in this collection:

• 32x32 inches: compact square alcove base
• 32x42 and 32x48 inches: mid-depth rectangular alcove
• 36x36 inches: standard square alcove, common ADA transfer stall size
• 36x48 and 36x54 inches: medium rectangular alcove
• 36x60 and 30x60 inches: standard 5-foot alcove, the most common tub replacement size
• 60x32 and 60x36 inches: wider alcove configurations

For corner installations, square and neo-angle bases are available in 36x36, 38x38, and 40x40 inch footprints.

Drain locations available across this collection include center, left, right, corner, and linear. When selecting a base, confirm your existing or planned drain rough-in location before purchasing. Relocating a drain during installation adds significant cost and labor.

Shower Base Materials

Acrylic capped ABS is the most common material in this collection, used in 26 products. ABS (acrylonitrile butadiene styrene) is a rigid structural core with an acrylic surface finish. The combination provides a lightweight, durable base with a smooth, easy-to-clean surface. Most DreamLine bases use this construction.

Acrylic bases make up 22 products in this collection. Acrylic is lightweight, available in the widest range of sizes, retains heat reasonably well, and resists mold and mildew with regular cleaning. Standard acrylic is the most common material for residential shower bases at every price point.

Solid surface accounts for 15 products. Solid surface material is a blend of natural minerals and resins that produces a non-porous, consistent-color surface. It is more durable than acrylic, easier to repair if scratched, and available in a matte finish that reduces surface reflection. Solid surface bases are the recommended choice for primary bathrooms with heavy daily use.

AcrylX is Aquatic's proprietary reinforced acrylic construction, used in 4 products. A fiberglass backing increases rigidity and reduces flex underfoot compared to standard acrylic.

All bases in this collection are available in white. Select DreamLine and Renovative Bath models are also available in black or bisque.

Handicap Shower Pan Pricing and Shipping

Shower bases in this collection are priced from approximately $270 for entry-level alcove bases up to $900 for larger solid surface configurations. All orders over $99 ship free.

When comparing prices across retailers, keep in mind that shower bases are typically purchased separately from the shower walls, door, and drain hardware. If you are doing a full shower renovation, confirm what components you need before ordering to avoid missing pieces. Our team can help confirm sizing, drain compatibility, and what additional items you will need for a complete accessible shower installation.

What is an ADA shower pan?

An ADA shower pan is a shower base designed to meet or reference the ADA accessibility standards for threshold height and entry width. The ADA standard calls for a zero or near-zero threshold at the shower entry and a minimum 36-inch clear opening for a transfer shower. ADA shower pans are used in accessible residential bathrooms, aging-in-place renovations, and commercial accessible restroom installations.

What is the difference between a barrier-free shower base and a low-threshold shower base?

A barrier-free shower base has no curb or threshold. The floor is flush with the bathroom floor and water drains by gravity slope. A low-threshold shower base has a minimal curb, typically under two inches, that creates a slight water barrier while keeping the step-over height low. Barrier-free is the correct specification for wheelchair users and roll-in shower installations. Low-threshold is appropriate for aging-in-place renovations where some water containment is preferred and full barrier-free entry is not required.

What size shower base do I need for an ADA shower?

The ADA standard for a transfer shower stall is 36x36 inches with a 36-inch clear entry. For a roll-in shower used by wheelchair users, the clear entry must be at least 60 inches wide. If you are replacing an existing tub in a standard residential alcove, the opening is typically 60 inches wide and 30 to 36 inches deep. Measure your rough-in opening from wall to wall and floor to ceiling before selecting a base, and confirm your drain rough-in location.

What is the difference between a shower base and a shower pan?

Shower base and shower pan refer to the same product: the waterproof floor unit at the bottom of the shower enclosure that directs water toward the drain. The terms are used interchangeably across brands and retailers.

What material is best for a handicap shower base?

For heavy daily use in an accessible bathroom, solid surface is the most durable option. It is non-porous, scratch-resistant, and available in a matte finish with built-in texture for slip resistance. Acrylic and acrylic capped ABS are appropriate for most residential applications and are available in a wider range of sizes. All bases in this collection include a textured or slip-resistant floor surface regardless of material.

Can I install a shower door on a barrier-free shower base?

Yes. Frameless sliding shower doors without a bottom track are compatible with barrier-free bases because they mount to the wall at the top and sides only, leaving the floor completely unobstructed. Confirm that your barrier-free base has a finished wall return on both sides of the entry opening before ordering a door. Browse our shower doors collection for frameless and semi-frameless options sized for accessible alcove showers.

How do I choose the right drain location for a shower base?

Drain location is determined by your existing plumbing rough-in. If you are replacing an existing base, match the drain location of the current base unless you are relocating the drain, which requires additional plumbing work. Center drain bases are the most widely available and work with most bathroom layouts. Left and right drain bases are used when the plumbing rough-in is positioned toward one side of the opening. Linear drains run along one wall and are used primarily in barrier-free floor designs.
