What Are the Standard Shower Base Sizes Ella's Bubbles Makes?

Ella's Bubbles makes its own acrylic shower bases in three standard sizes, 30x60, 32x60 and 36x60 inches, each with a left or right drain, and it offers wheelchair accessible roll-in pans in the same three footprints along with made-to-order rectangular bases for spaces a standard size will not fit. The full lineup of bases, wall panels and surrounds is introduced in Shower Bases and Wall Panels. This page gathers the sizes, drain positions and threshold styles in one place so you can compare them with your opening before your contractor cuts the floor.

The Standard Sizes at a Glance

Every figure in this table appears on a published Ella page. Where a page does not state a figure, the cell says not listed rather than guessing.

BaseSize (inches)Drain and thresholdBest for
Standard acrylic base30x60Left or right drain in a set position; threshold not listedThe simplest choice when it fits the opening

Custom rectangular baseUp to 44x80Left, right or center drain at least 9 inches from each wall; about 3 inch threshold, or zero thresholdOpenings no standard size matches

The differences come down to two decisions. The first is footprint: the three standard sizes share a 60 inch length and differ only in width, so a 30, 32 or 36 inch deep opening is usually covered without a custom order. The second is the entry. A standard or step-in base has an edge to step over, a roll-in pan has no curb at all, and the SMC reversible base sits between them with its 1 inch profile. If your opening is not one of these sizes, or you need the drain somewhere other than the set left or right position, the custom program is the route, and its limits are described in What Is the Largest Custom Shower Base Ella's Bubbles Can Make?.

What a Shower Stall Is, in Ella Terms

A shower stall is the base on the floor plus the walls that enclose it, and Ella sells those pieces per item rather than as one bundle. You choose the base in your size, then the wall panels, and then any seat, grab bar, screen or filler piece the space needs. The base is finished acrylic and is ready to use once installed; it does not need to be tiled over. Your contractor sets the base, connects the drain and finishes the walls around it.

The wall side of the stall is just as standardized as the base. Ella shower wall panels are manufactured 98 inches high, with the back wall panel measuring 60 inches wide and side panels listed at 40 inches; the three-piece acrylic wall systems also list 36 to 38 inch side walls at 96 to 98 inches tall. Panels come in a plain white finish, a CNC routed design with light gray grout lines, and a digital print option. An 8 inch wide L-shaped plastic filler piece closes a gap between the base and an adjoining wall or fixture, and because it is plastic it can be trimmed down if the space is smaller than the piece. The wall options and the filler piece are detailed in Shower Bases, Walls, and Filler Pieces.

Standard, Roll-In or Step-In: Which Entry Fits the Bather

  • Standard acrylic base. The set left or right drain makes it the easiest to plan around existing plumbing. If one of the three standard sizes fits, it is the simplest choice.
  • Roll-in base. Built for a wheelchair, walker or shower chair to pass straight from the bathroom floor into the stall. Because there is no curb, a self-adhesive collapsible rubber dam across the entry holds the water in: it flattens under a wheel and springs back once the wheel passes. On tile floors the grout line beneath the dam must be caulked, and the base threshold must never be drilled, because drilling voids the base warranty. The 32x60 roll-in base ships in left and right versions and is ready to ship. What a roll-in stall includes is explained in What is a roll-in shower for wheelchair users?.
  • 3 inch step-in base. For a bather who does not need a flat approach and prefers a raised edge that keeps water in without a dam.
  • SMC 1 inch reversible base. A low profile you step over, offered alongside an SMC barrier-free linear-drain base that belongs to the roll-in family.

Drain Position and Threshold Details

On a standard base the drain sits in a set position for that size, left or right. Custom bases can place the drain left, right or center, but it must be at least 9 inches from each wall, so a drain only 7 inches from the threshold edge cannot be produced even on a custom pan. Custom bases are rectangular only, made for three-wall alcoves and corner installations, and the largest is 44 inches wide by 80 inches long. A 36 by 36 inch corner base has been built with the drain set 9 and 5/8 inches from each of two adjacent walls, which shows how precisely the location can be specified. The online drain-placement tool can round measurements up to the nearest inch, so confirm your exact drain location with the team at (800) 480-6850 before the base is built. The measuring steps are in Walk-In Tub and Shower Base Sizes and How to Measure for Fit.

Threshold height is the other choice. A custom base typically has a threshold of about 3 inches, and a zero threshold version sits flush with the surrounding floor instead. If the installation is on a concrete slab with no access from below, or the existing drain is in an unusual spot, open a ticket at ellasbubbles.com/support with a simple drawing showing the walls, the size you want and where the drain is, and the team confirms whether a base can be made to match.

Cultured Marble Bases

Alongside the acrylic bases, Ella presents cultured marble shower bases in three sizes. The video shows these molded solid bases with their glossy gel coat finish and ADA compliant slip resistant textured floor, and it makes one planning point clear: they are heavy and require at least two people to install, so tell your contractor which base type you are ordering. The specific cultured marble sizes are not stated in the video, so confirm them with your Ella dealer or the team at (800) 480-6850.

Common Questions

What standard shower base sizes does Ella's Bubbles make?
Ella manufactures its own acrylic shower bases in standard sizes of 30x60, 32x60 and 36x60 inches. Each is available with a left or right drain in a set position for that size. Wheelchair accessible roll-in pans come in the same three footprints.
Which shower base size works for a wheelchair?
The barrier-free roll-in base is offered in 32x60 inches in left and right configurations and is ready to ship, and ADA curb-less pans are listed in 30x60, 32x60 and 36x60 inch sizes. A collapsible rubber dam across the entry holds the water in without a curb. Never drill the base threshold, because that voids the base warranty.
Can I get a shower base in a size that is not standard?
Yes. Custom rectangular bases are made up to 44 inches wide by 80 inches long, with a left, right or center drain at least 9 inches from each wall. Angled or curved bases are not offered.
How tall is the threshold on an Ella shower base?
A custom base typically has a threshold of about 3 inches, and a 3 inch step-in threshold base is also offered. Zero threshold and roll-in bases sit flush with the floor, and the SMC reversible base has a 1 inch profile. The threshold on the three standard acrylic sizes is not listed, so confirm it with the team.
Do Ella shower bases need to be tiled over?
No. Standard and custom Ella shower pans are finished acrylic and are ready to use once installed. Your contractor sets the base, connects the drain and finishes the walls around it.
What size are the wall panels that go with the base?
Ella shower wall panels are 98 inches high, with a 60 inch back wall and side panels listed at 40 inches; the three-piece systems also list 36 to 38 inch side walls. Finishes include plain white, a CNC routed tile look with light gray grout lines, and a digital print option.
